post burn contracture neck scar release reconstruction

This clinical photograph shows a front-view of a patient's neck and upper torso one year after a secondary burn scar reconstruction. Centered on the anterior neck is a large, well-integrated pre-expanded Anterolateral Thigh (ALT) free flap used to release a sternomental contracture. The flap displays a uniform, slightly meshed texture and is paler than the surrounding skin, with clearly defined surgical margins and healed suture lines at its perimeter. Below and adjacent to the flap, the upper chest and right shoulder area exhibit significant post-burn sequelae, characterized by extensive mottled scarring, hypertrophic changes, and irregular patches of hyperpigmentation and hypopigmentation. The image illustrates the successful surgical management of complex burn-related neck contractures through microsurgical flap transfer, demonstrating improved range of motion and aesthetic outcome in reconstructive plastic surgery.

Post-Burn Contracture: A Comprehensive Essay with Recent Advances

1. Introduction

Burn injuries remain a major global health burden, with an estimated 11 million people seeking medical care for burns annually. Among the most debilitating long-term sequelae is the post-burn contracture (PBC) - a pathological shortening of scar tissue across a joint or mobile surface that limits function and causes aesthetic deformity. Nearly one-third of all burn patients develop contractures at some point in their recovery, and the economic and psychosocial burden is immense. The upper extremity (particularly the hand) and the neck are the two most commonly affected regions. Managing PBC demands a thorough understanding of its pathophysiology, a systematic classification approach, and access to a wide reconstructive armamentarium - from simple Z-plasties to free microvascular tissue transfer.

2. Pathophysiology of Post-Burn Contracture

The development of PBC involves a complex, time-dependent series of wound healing events:

2.1 Phases of Scar Formation

  • Inflammatory phase (0-3 days): Cytokine release (TGF-β1, PDGF, IL-1, IL-6) recruits fibroblasts and myofibroblasts to the wound site.
  • Proliferative phase (3 days - 3 weeks): Fibroblasts lay down disorganized Type III collagen. Myofibroblasts - smooth muscle actin-expressing cells - generate the contractile force that progressively shortens the scar. This is the principal cellular driver of contracture.
  • Remodeling phase (3 weeks - 2 years): Type III collagen is replaced by Type I collagen with cross-linking. In hypertrophic scars the remodeling is dysregulated, resulting in persistent scar thickening and contracture.

2.2 Key Molecular Mediators

  • TGF-β1/β2: The dominant pro-fibrotic cytokines. They promote myofibroblast differentiation, collagen synthesis, and inhibit matrix metalloproteinases (MMPs) responsible for collagen degradation.
  • TGF-β3: Counter-regulatory; promotes scar-free healing and is a target for pharmacological intervention.
  • CTGF (connective tissue growth factor): Downstream mediator of TGF-β-driven fibrosis.
  • MicroRNA regulation: Emerging evidence highlights miR-21, miR-29, and miR-200 as key post-transcriptional regulators of the fibrotic cascade. miR-29 suppresses collagen genes and its downregulation in burns promotes fibrosis. Gene-miRNA crosstalk is an active frontier of research.

2.3 Biomechanical Factors

Full-thickness burns destroy the dermis, eliminating the mechanical resistance it provides to myofibroblast contraction. Even with early excision and grafting, split-thickness skin grafts (STSGs) undergo secondary contraction of 20-40%, while full-thickness skin grafts (FTSGs) contract considerably less (~5%). Skin grafts also lack elastin, contributing to long-term stiffness. Immobility, edema, and joint positioning in the acute phase further accelerate contracture development.

3. Classification of Post-Burn Contracture

Several classification systems are in use:

3.1 By Location

  • Cervical contracture (anterior neck - chin to sternum, most common site in developing countries)
  • Axillary contracture
  • Antecubital (elbow) contracture
  • Wrist and hand contracture (most common in industrialized nations)
  • Popliteal (knee) contracture
  • Perioral contracture
  • Eyelid contracture (ectropion)

3.2 By Depth/Type

TypeDescription
Linear/cord-likeBand of scar tissue across a joint
Sheet-like (planar)Diffuse scar involving a large area
Web contractureTypically seen in axilla and first web space of hand
Severe/complexInvolvement of deep structures (tendon, joint capsule, bone)

3.3 Severity Grading (Neck - Aydın's classification)

  • Grade I: Neck mobility partially restricted; platysma visible
  • Grade II: Neck mobility severely restricted; chin-sternum distance decreased
  • Grade III: Neck mobility completely absent; chin fused to chest

3.4 Functional Grading (Hand - Kurtzman classification)

  • Grade 0: Normal
  • Grade I: Mild functional deficit
  • Grade II: Moderate functional deficit (occupational therapy alone insufficient)
  • Grade III: Severe functional deficit requiring reconstruction

4. Prevention

Prevention begins at the moment of injury and continues through the entire rehabilitation phase - "Prediction, prevention, and treatment of potential functional and aesthetic morbidity now starts at the time of initial resuscitation." (Current Surgical Therapy, 14e)

4.1 Acute Phase Measures

  • Splinting and positioning: Joints should be splinted in the anti-contracture position from day one. For the hand: MCPs at 70-90° flexion, IPs in full extension, wrist 15-30° extension, thumb in abduction. For the neck: extension with a cervical collar or pillow positioning.
  • Early excision and grafting: Excising full-thickness wounds within 48-72 hours and covering with skin grafts reduces contracture risk by shortening the inflammatory phase and preventing prolonged wound contraction.
  • Judicious fluid resuscitation: Avoiding over-resuscitation reduces edema, which contributes to tissue stiffness and poor joint range of motion.

4.2 Rehabilitation Phase Measures

  • Compression garments: Custom-fitted pressure garments (>25 mmHg) worn 23 hours/day for 6-24 months remain the standard of care for hypertrophic scar prophylaxis. They act via local ischemia, reduced collagen synthesis, and altered cytokine milieu.
  • Silicone gel sheeting: Used alone or under pressure garments; reduces scar vascularity and thickness, likely via local hydration and temperature effects.
  • Physiotherapy and occupational therapy: Active and passive range-of-motion exercises, splinting during sleep, and task-specific activities are cornerstones of preventing joint stiffness.
  • Massage therapy: Improves scar pliability and reduces pruritus. A 2024 systematic review confirmed massage, laser, and shockwave therapy all improve pain and pruritus after burns (Santuzzi et al., J Physiother 2024).

5. Timing of Surgical Reconstruction

The classical teaching is to wait for scar maturation (12-18 months) before reconstruction. However, this principle has been modified:
  • Emergency reconstruction: Ectropion causing corneal exposure, severe microstomia, severe neck contracture threatening airway, or tourniquet-like constriction require urgent or semi-urgent intervention regardless of scar maturity.
  • Early reconstruction (within 6 months): Growing children at risk of developmental deformity (e.g., hand contractures limiting prehension), or cases with rapidly developing joint contracture not responding to therapy.
  • Elective reconstruction (12+ months): Once scar is pale, flat, and soft (mature), predictable surgical outcomes are achievable.
A key principle from Current Surgical Therapy 14e is that the acute care, rehabilitation, and reconstruction are integrated from the beginning: "The primary goals of burn reconstruction are restoration of function and form via the prevention and treatment of contractures and hypertrophic scarring."

6. Surgical Management

The reconstructive ladder - from simple to complex - guides surgical decision-making.

6.1 Local Tissue Rearrangement

Z-Plasty is the workhorse of local scar release. It involves transposing two triangularly based flaps to lengthen a linear scar. Classic Z-plasty with 60° limb angles yields a theoretical 75% lengthening and a 25% increase in overall scar length. Multiple Z-plasties ("running" or "jumping man") distribute tension across longer scars. A 2024 review by Donelan and Buta in Clinical Plastic Surgery highlights Z-plasty and its variants - W-plasty, compound Z-plasties, and the "jumping man" - as highly effective for band-like contractures across concave surfaces (PMID 38789143).
Y-V and V-Y plasties are used for smaller localized scar bands, particularly in web spaces.
Four-flap and five-flap Z-plasties provide greater lengthening and are used for first web space contractures.

6.2 Skin Grafting

  • Split-thickness skin grafts (STSG): Harvested from donor sites (thigh, back) at 0.012-0.018 inches thick. Sheet grafts (unmeshed) are preferred on the face, hands, and neck for superior aesthetic and functional outcomes. Sheet grafts contract less than meshed grafts. STSGs are the most commonly used technique for burn reconstruction (n=89 in the Raborn & Janis 2024 scoping review of 327 publications; PMID 38250207).
  • Full-thickness skin grafts (FTSG): Harvested from groin, post-auricular, supraclavicular, or antecubital areas. Undergo minimal secondary contraction and are preferred for the hand (palmar surface, fingers), eyelids, and face. Donor site must be primarily closed.
  • Composite grafts: Include dermis + epidermis + occasionally fat; used in smaller areas such as the alar base, eyelids, and fingertip.

6.3 Tissue Expansion

Tissue expanders inserted subcutaneously adjacent to the scar allow generation of large amounts of local tissue with similar color, texture, and thickness. The expanded skin is then used to resurface the contracture release defect. Particularly useful for scalp, neck, and facial reconstruction. Complications include expander extrusion, infection, and implant failure, but with careful planning, tissue expansion delivers excellent donor-recipient color match.

6.4 Flap-Based Reconstruction

Flaps are the most commonly reported technique in burn contracture management and are favored for large contractures, exposed deep structures, joint contractures, and recurrent contractures after prior grafting.
Pedicled flaps:
  • Rotational, advancement, and transposition flaps using adjacent unburned skin
  • Perforator-based flaps: e.g., thoracodorsal artery perforator (TDAP) flap for axillary contracture; medial sural artery perforator (MSAP) flap for popliteal contracture
  • Reverse radial forearm flap: For dorsal hand contractures
  • Latissimus dorsi flap: For large shoulder/axillary/elbow contractures (as illustrated in clinical images above)
Free flaps (microsurgical reconstruction):
  • Indicated when local tissue is unavailable, contractures are severe/recurrent, or joints are involved
  • Anterolateral thigh (ALT) free flap: The most versatile workhorse - thin, pliable, and can be harvested as fascio-cutaneous, muscle, or chimeric flap. Widely used for neck and elbow contractures
  • Radial forearm free flap: Thin and pliable for hand and face
  • Gracilis muscle flap: With skin paddle for complex defects
A landmark 2025 systematic review and meta-analysis by Elemosho et al. (Microsurgery, 2025; PMID 40817644) analyzed 27 studies with 830 joint contractures and found:
  • Contracture resolution: 98.9% for pedicled flaps and 90.1% for free flaps
  • Recurrence rate: 1.8% (pedicled) and 0.6% (free flap)
  • Total flap loss was low: 1.5% (pedicled) and 2.9% (free flap)
  • No significant difference in outcomes between pedicled and free flap types (p=0.50)
This strongly supports flap-based reconstruction as the gold standard for joint contracture, with both pedicled and free techniques being highly effective.

6.5 Hand Contracture Reconstruction

The hand deserves special mention due to the complexity of its functional anatomy. Post-burn hand deformities include:
  • Dorsal skin contracture with MCP hyperextension and IP flexion ("claw hand")
  • First web space contracture (thumb adduction contracture)
  • Palmar contracture with finger flexion
  • Boutonnière and swan-neck deformities
A stepwise approach (Vosinakis et al., Burns, 2024; PMID 39423713) in their systematic review of 1,310 patients found that no single reconstruction technique is superior. Meticulous preoperative planning and intensive rehabilitation are essential. Key techniques include:
  • FTSG for dorsal hand (superior to STSG)
  • Perforator flaps and pedicled groin flap for larger defects
  • Fasciocutaneous free flaps (ALT, radial forearm) for complex joint contractures
  • Tenolysis, capsulotomy, and arthrolysis for underlying joint stiffness

7. Non-Surgical Adjunct Treatments

7.1 Intralesional Injections

  • Triamcinolone acetonide (10-40 mg/mL): Suppresses fibroblast activity, reduces collagen synthesis, and softens hypertrophic scars. Often used in series (every 4-6 weeks). Risk of skin atrophy and telangiectasia.
  • 5-Fluorouracil (5-FU): Anti-proliferative; used alone or in combination with steroids for resistant scars.
  • Bleomycin: Anti-fibrotic; intralesional injection disrupts collagen cross-linking.
  • Botulinum toxin A: Inhibits myofibroblast activity via reduction of mechanical tension; emerging role in preventing and treating hypertrophic scars.

7.2 Laser Therapy

Laser therapy has become central to scar management. Two main technologies dominate:
  • Fractional CO₂ laser (ablative, 10,600 nm): Creates microscopic ablation columns surrounded by coagulation zones. Stimulates collagen remodeling, elastin neogenesis, and soft-tissue relaxation. Improves scar thickness, pliability, range of motion, and symptoms (pain, pruritus). The fractional approach allows rapid re-epithelialization within 48 hours from adjacent untreated tissue (Current Surgical Therapy 14e). This is now considered the "workhorse" for mature thick contracted burn scars.
  • Pulsed-dye laser (PDL, 585/595 nm): Targets oxyhemoglobin in scar vasculature; reduces erythema and thickness of early hypertrophic scars. Less effective for contracture than ablative lasers.
  • Non-ablative fractional lasers (1540/1550 nm Erbium): Produce columns of dermal coagulation without surface ablation; useful in pigmented skin or areas requiring minimal downtime.
A 2023 systematic review (PMID 36749436) confirmed fractional CO₂ and Er:YAG lasers outperform microneedling for hypertrophic scar improvement.

8. Recent Advances (2022-2026)

8.1 Dermal Substitutes

Dermal substitutes aim to replace lost dermis, improving scar quality by providing a scaffold for dermal regeneration. A 2024 systematic review and meta-analysis (van den Bosch et al., Wound Repair Regen; PMID 39435560) of 31 comparative trials found:
  • Collagen-elastin matrix caused a delay in re-epithelialization (-7.3%) compared to STSG in acute burns
  • Acellular dermal matrix (ADM) significantly improved subjective scar quality at 6 months compared to STSG alone (-1.95 on standardized scales; p<0.01)
  • Dermal substitutes hold promise for enhancing scar quality, though their use requires staged procedures
Current dermal substitutes in use:
  • Integra (bovine collagen + glycosaminoglycan matrix): Two-stage - first layer provides dermal regeneration, then STSG placed at 3-4 weeks
  • Matriderm (collagen-elastin matrix): Single-stage with STSG
  • AlloDerm (acellular human dermis): Available for immediate single-stage reconstruction

8.2 Fat Grafting

Autologous fat grafting (lipofilling) has emerged as a powerful adjunct for burn scar reconstruction. Harvested from the abdomen/thighs via liposuction, the fat (rich in adipose-derived stem cells, ADSCs) is injected into and around hypertrophic scars and contractures. Mechanisms of benefit include:
  • Paracrine effects of ADSCs reducing local fibrosis (downregulation of TGF-β1)
  • Improved scar pliability and reduction of contracture tightness
  • Improved skin quality (texture, color, elasticity)
  • Pain relief in post-burn neuropathic areas
Fat grafting is now used both as a standalone treatment and as an enhancer prior to laser or surgical intervention. Multiple sessions may be required.

8.3 Tissue Engineering and Bioengineered Skin

Next-generation wound coverage products represent the forefront of burn care:
  • Cultured autologous keratinocyte sheets (CEA - Epicel): Used for massive burns; however, fragile and susceptible to contracture
  • 3D bioprinted skin constructs: Using bio-inks containing fibroblasts, keratinocytes, and endothelial cells to fabricate skin-like structures with dermal architecture. Currently transitioning from experimental to early clinical use (2024-2025)
  • Composite skin substitutes (StrataGraft, etc.): Bi-layered constructs combining allogenic cells on a scaffold; approved for clinical use in some centers for deep partial-thickness burns to reduce scarring
  • 3D-printed splints: Custom-manufactured for axillary and other complex contractures - an innovation presented at the 2025 ISBI Regional Conference, offering improved compliance and fit over traditional thermoplastic splints

8.4 Gene Therapy and Molecular Targets

Emerging research targets the molecular drivers of fibrosis:
  • TGF-β pathway inhibition: Anti-sense oligonucleotides and siRNA targeting TGF-β1 have shown efficacy in animal models; clinical trials pending
  • MicroRNA therapeutics: miR-29 mimics and anti-miR-21 agents reduce collagen deposition in preclinical burn models (MDPI Int J Mol Sci, 2025)
  • Gene editing (CRISPR-Cas9): Targeting fibrosis genes in myofibroblasts; still experimental
  • Stem cell therapy: Bone marrow-derived MSCs and ADSCs reduce scar formation via paracrine anti-inflammatory and anti-fibrotic mechanisms

8.5 Neuromodulation

A 2026 Nature Communications Medicine paper highlights neuromodulation strategies in post-burn rehabilitation including transcutaneous electrical nerve stimulation (TENS), transcranial magnetic stimulation, and wireless microcurrent stimulation - targeting both scar remodeling and neuropathic pain, which commonly co-exist with contracture.

8.6 Perforator Flap Innovations

Refinements in perforator flap anatomy and the advent of color duplex ultrasonography and CT angiography for preoperative perforator mapping have greatly expanded the reconstructive toolkit:
  • Super-thin and supra-fascial flaps reduce donor-site morbidity
  • Pre-expanded free perforator flaps (combined tissue expansion + free flap) allow coverage of very large burn contracture areas (neck, chest) with minimal donor scarring
  • Chimeric flaps (combining two or more distinct flap territories on a single pedicle) allow reconstruction of three-dimensional defects in a single stage

8.7 Microsurgical Outcomes - Level 1 Evidence

The 2025 Elemosho et al. meta-analysis (PMID 40817644) provides the highest-quality evidence to date for microsurgical reconstruction, showing that flap-based techniques achieve contracture resolution in >90-99% of cases with low recurrence, firmly establishing flap reconstruction over grafting alone for joint contractures.

9. Special Situations

9.1 Pediatric Burn Contracture

Children present unique challenges because scar tissue does not grow with the child, leading to progressive deformity as skeletal growth occurs. Earlier intervention thresholds are warranted. Facial and hand contractures in children may cause secondary skeletal changes (mandibular dystrophy, short metacarpals). Airway management in pediatric patients with facial/neck contractures requires special consideration - a 2022 systematic review (PMID 35137105) found that video laryngoscopy and awake fiberoptic intubation are the safest techniques.

9.2 Neck Contracture

Cervical contracture is particularly significant because it may compromise the airway, cause chin-to-chest fusion, restrict shoulder motion, and produce lower lip ectropion. Management follows a spectrum from Z-plasty (mild linear bands) to FTSG (moderate, with good recipient bed) to free ALT flap (severe/recurrent/large area). The pre-expanded ALT free flap has been described as the optimal solution for large anterior neck contractures (shown in clinical images above), providing large, pliable, skin-matched tissue in one or two stages.

9.3 Axillary Contracture

Often presents as web-type scar restricting shoulder abduction. The five-flap Z-plasty (jumping man) is ideal for mild-to-moderate axillary bands. For severe contractures, the TDAP or LD flap provides reliable coverage. 3D-printed airplane splints have been reported for postoperative positioning (ISBI 2025).

10. Post-Operative Care

  • Immobilization: Splinting in the position of maximum correction for 5-7 days, followed by early mobilization
  • Rehabilitation: Active and passive ROM exercises initiated within 5-7 days of surgery
  • Pressure garments: Recommended for 6-18 months post-grafting to prevent recurrence
  • Silicone gel sheeting: Applied once wounds are healed
  • Scar monitoring: Monthly assessments with validated tools (Vancouver Scar Scale, POSAS)
  • Laser therapy: Fractional CO₂ laser sessions commenced from 3-6 months post-op to improve scar quality and prevent recurrence

11. Prognosis and Outcomes

  • Contracture recurrence remains the most common complication, especially with skin grafting alone (higher rates with STSG than FTSG)
  • Flap-based reconstruction offers the lowest recurrence rates (0.6-1.8% with microsurgical flaps per Elemosho 2025 meta-analysis)
  • Hand contractures have the most complex rehabilitation trajectory and functional recovery depends on adherence to therapy
  • Psychosocial impact is significant; body image disturbance, depression, and occupational disability are common; multidisciplinary care incorporating psychology is essential

post burn neck contracture grade severity classification clinical photograph

Clinical photograph of a patient in a supine position, demonstrating severe post-burn sequelae affecting the lower face, neck, and upper chest. Key clinical findings include extensive hypertrophic scarring and contracture bands extending from the submental region to the infraclavicular area. The neck contracture has resulted in a fixed flexion deformity at the atlanto-occipital joint, severely restricting cervical extension. Facial involvement is marked by microstomia (restricted mouth opening) and eversion of the lower lip (ectropion) with exposed mucosa. The skin exhibits multi-chromatic dyspigmentation, including areas of hypopigmentation, erythema, and hyperpigmented scarring, along with possible crusting or eschar near the base of the neck. The patient is shown in a perioperative or critical care setting, indicated by the surgical cap, head support, and gloved medical personnel, likely preparing for airway management or reconstructive surgery. This image serves as a significant clinical example of complex burn contractures and the associated challenges in managing difficult airways and physical rehabilitation.

Clinical photograph of a pediatric patient (approximately 5 years old) presenting with a severe, recurrent post-burn contracture (PBC) of the neck and upper chest. The affected area exhibits extensive hypertrophic scarring and keloid-like tissue formation, characterized by irregular, raised textures and varying hyperpigmentation ranging from pink to deep reddish-brown. The contracture significantly affects the cervicomental angle and sternomental distance, causing a downward traction on the lower facial structures. Visually, this is manifested as an eversion or pulling down of the lower lip (ectropion of the lip), resulting in a partially open mouth and blunting of the mandibular definition on the affected side. The image illustrates the complex secondary deformities associated with severe burn sequelae in the head and neck region, specifically the functional and aesthetic impact of scar contracture on facial symmetry and range of motion. It serves as an educational example for plastic and reconstructive surgery planning, highlighting the challenges of managing recurrent scarring in pediatric burn patients.

This composite clinical photograph series (A, B, C) demonstrates severe post-burn neck contracture in a pediatric patient. Frontal and lateral views reveal extensive hypertrophic scar tissue involving the anterior neck and extending inferiorly to the chest wall and superiorly toward the clavicles. The scar presents as a dense, irregular, and raised band of tissue with mixed hyper- and hypopigmentation. Key clinical findings include severe obliteration of the cervicomental angle (B), a permanent 'bowed down' head posture indicative of significant restriction in neck extension and flexion (C), and lower lip incompetence characterized by traction-induced ectropion where the lip is pulled inferiorly away from the gingiva (A). These visual features are consistent with Onah type 3c severe anterior neck contracture, illustrating the functional and aesthetic morbidity associated with unmanaged thermal injury, including restricted range of motion and facial secondary deformities.

This clinical photograph displays a frontal view of a patient’s face and neck, illustrating the long-term sequelae of severe burn injuries. The image captures extensive, diffuse post-burn scarring across the lower face and neck, characterized by a mixture of hypopigmented and hyperpigmented areas and irregular, hypertrophic texture. A significant vertical scar contracture is visible on the neck, which is actively pulling down the mandible. This mechanical tension has resulted in a marked mandibular deformity and secondary dental malocclusion. The patient's mouth is open, revealing an asymmetrical, V-shaped dental arch in the lower jaw where the teeth are misaligned and tilted anteriorly due to the chronic traction from the neck contracture. The image serves as a clinical example of how unreleased soft tissue contractures can lead to permanent skeletal and occlusal changes, necessitating combined plastic surgical release and orthodontic or orthognathic intervention.

This clinical photograph displays severe, chronic post-burn complications in a pediatric or adolescent patient. The image shows extensive hypertrophic scarring and tissue contracture affecting the face, neck, and upper torso. Notable features include a severe neck contracture that has pulled the chin downward toward the chest, resulting in a marked mandibular deformity and persistent open-mouth posture (ectropion of the lower lip). The oral cavity exhibits significant distortion with dental malocclusion and a protruding tongue, likely exacerbated by soft tissue traction. The skin across the anterior chest and neck is characterized by irregular texture, areas of both hyperpigmentation and hypopigmentation (depigmentation), and dense fibrous bands. A web-like contracture is also visible in the left axillary and antecubital region, significantly restricting the range of motion. This image illustrates the long-term sequelae of inadequately managed severe burns, highlighting the critical need for early anti-contracture positioning, splinting, and surgical reconstruction in burn rehabilitation.

Clinical photograph of an 8-year-old female patient demonstrating a severe recurrent post-burn contracture of the neck. The image reveals extensive hypertrophic scarring extending from the lower face and perioral region down to the upper chest. Key findings include prominent longitudinal bands of scarred, thickened skin (cicatricial bands) that pull the chin toward the sternum, resulting in a distorted cervicomental angle and restricted neck extension. The skin exhibits significant dyspigmentation, characterized by a mosaic pattern of hyperpigmented dark brown patches and hypopigmented (depigmented) areas on the chest and neck. The lower lip appears slightly retracted due to the tension from the cervical contracture, and the normal anatomical contours of the neck are obliterated by tight, inelastic scar tissue. This case illustrates the functional and aesthetic impairment common in pediatric burn survivors with recurrent contractures following previous skin grafting.

post burn hand contracture grades severity clinical photo

Clinical photograph of a young patient's hand and forearm demonstrating severe post-burn contractures, specifically following an electrical injury. The image shows extensive hypertrophic scarring and tissue fibrosis spanning the forearm and hand. There is a prominent mottled skin appearance with areas of hypopigmentation (leukoderma) centrally along the forearm and palm, surrounded by hyperpigmentation. The hand is fixed in a non-functional, clenched posture characterized by severe flexion contractures of the fingers and adduction of the thumb. These findings indicate a significant loss of range of motion and functional impairment, including inability to perform basic grasping or manipulation. The clinical presentation is characteristic of poorly managed or chronic severe burn wounds, where contracting scar tissue leads to permanent orthopedic and soft tissue deformities. This visual is used to teach the consequences of delayed plastic surgical intervention, such as contracture release and skin grafting, in resource-limited settings.

Left: A 32-year-old female presents with severe post-burn sequelae on the bilateral upper extremities. The skin demonstrates diffuse, mottled dyspigmentation and textural irregularities consistent with extensive scarring and previous split-thickness skin grafting (STSG). A rigid 90-degree flexion contracture of the elbow is evident. Middle: Intra-operative view showing a large soft tissue defect at the elbow following release of the burn scar and lacertus fascia, and lengthening of the biceps tendon. The surgical field reveals exposed deeper tissues prepared for reconstruction. Right: Post-reconstruction view showcasing a successful free Anterolateral Thigh (ALT) flap used to cover the 12x12 cm defect. The flap is secured with visible circumferential sutures at the elbow joint, and the limb is shown in improved extension. The case illustrates advanced plastic surgery techniques including contracture release and microsurgical free flap reconstruction for complex burn injuries.

A composite of four clinical photographs demonstrating the preoperative state and surgical planning for a post-burn elbow contracture. The top panels show the affected arm with extensive scarring, hyperpigmentation, and hypopigmentation, illustrating an unstable scar and significant flexion contracture of the elbow joint. The bottom-left panel details the preoperative surgical markings for a trilobed perforator flap. The markings define three adjacent skin flaps labeled 'a', 'b', and 'c' in descending order of size (indicated by the notation 'a>b>c'), designed to be rotated to release the contracture. The bottom-right panel displays the area after initial surgical steps or secondary healing, with labels corresponding to the planned flap locations. This sequence illustrates the reconstructive plastic surgery approach using a specialized perforator flap technique to restore joint mobility and skin integrity in a patient with severe thermal injury sequelae.

Here is a comprehensive clinical image gallery organized by anatomical site and grade of post-burn contracture:

Clinical Images: Grades of Post-Burn Contracture

NECK CONTRACTURE (Aydin's / Onah Classification)

Grade II - Severe restriction, decreased chin-sternum distance

Grade II neck contracture - hypertrophic scarring with severely restricted cervical extension and lower lip ectropion
Grade II neck contracture in an 8-year-old female. Extensive hypertrophic scarring with longitudinal cicatricial bands pulling the chin toward the sternum, obliterated cervicomental angle, restricted neck extension, and dyspigmentation (hyper + hypopigmented mosaic). The lower lip shows traction-induced retraction. Previous skin grafting visible.

Grade III - Complete fusion, chin-to-chest (Onah Type 3c)

Grade III neck contracture - complete cervical fusion with chin-to-chest deformity, ectropion, and axillary web contracture
Grade III (most severe) neck contracture. Chin pulled completely down to chest, severe mandibular deformity, persistent open-mouth posture with lower lip ectropion, dental malocclusion, and protruding tongue from soft tissue traction. Note the co-existing left axillary web contracture. This represents the consequences of inadequately managed severe burns.

Grade III with secondary skeletal deformity

Severe neck contracture with chin-to-chest posture and mandibular deformity from chronic scar traction
Grade III neck contracture with secondary skeletal involvement. The vertical scar band actively pulls the mandible downward, resulting in mandibular deformity and dental malocclusion (V-shaped lower arch with anterior tilt of teeth). Demonstrates how unreleased contractures cause permanent skeletal change over time.

Severe neck contracture - perioperative setting

Severe cervical contracture causing fixed atlanto-occipital flexion and microstomia, perioperative airway management
Grade III neck contracture - perioperative view. Fixed atlanto-occipital flexion deformity with severe restriction of cervical extension, microstomia, and lower lip ectropion. Patient is being prepared for airway management - demonstrating why these cases require anticipated difficult airway protocols. Multi-chromatic dyspigmentation and dense contracture bands visible from submentum to infraclavicular region.

Pediatric recurrent neck contracture (post-grafting)

Pediatric recurrent post-burn neck contracture with keloid-like scarring and lower lip traction
Recurrent Grade III pediatric neck contracture (~5 years old) following prior reconstruction. Keloid-like raised tissue, mixed hyperpigmentation (deep reddish-brown to pink), cervicomental obliteration, and lower lip ectropion from downward traction. Highlights the challenge of contracture recurrence in children as the skeleton grows.

AXILLARY CONTRACTURE

Type 1a - Anterior axillary fold contracture (mild-moderate)

Type 1a axillary post-burn contracture with preop markings for square flap and 1-year result with full shoulder abduction
Type 1a axillary contracture - right anterior axillary fold, pediatric patient. Hypertrophic scarring with skin tethering causing limited shoulder abduction. Treated with square flap + transposition flaps. One-year follow-up shows full 180° shoulder abduction - demonstrating excellent outcome with local tissue rearrangement for early-grade axillary contracture.

Type II - Severe axillary contracture (shoulder abduction 45°)

Type II left axillary post-burn contracture in 29-year-old male, treated with modified propeller flap, 3-year follow-up showing full abduction
Type II axillary contracture in a 29-year-old male. Severe anterior chest wall scarring with shoulder abduction limited to 45°. Treated with modified propeller flap (zig-zag design, 90° rotation). Three-year follow-up shows complete restoration of overhead abduction with good scar remodeling.

HAND CONTRACTURE

First web space contracture

Severe first web space thumb adduction contracture with thumb in fixed adducted position, pre and post posterior interosseous flap repair
First web space contracture - pediatric patient. (a) Fixed thumb adduction contracture with hypertrophic scarring, hyperpigmentation, and finger flexion deformities. (b) After surgical release using a posterior interosseous flap - significant improvement in thumb abduction and functional position restored.
First web space contracture intraoperative defect after release showing exposed tissue bed, thumb extended manually
First web space contracture - intraoperative. Following contracture release, the open defect between thumb and index finger is seen with exposed deep tissue. Thumb is being manually extended to demonstrate the restored web space - the defect now requires flap or graft coverage.

Second web space contracture (with intraoperative planning)

Second web space contracture pre and post ulnar-sided index finger transposition flap repair
Second web space contracture in a 32-year-old male. Preoperative markings showing the planned contracture release. Postoperative result after ulnar-sided index finger transposition flap with FTSG to donor site - successfully widening the web space and restoring thumb-index pinch function.

Digital flexion contracture (ring and little fingers)

Post burn ring and little finger contracture with STSG grafts showing restricted extension and skin graft pigmentation changes
Digital flexion contracture affecting the 4th and 5th digits. Inward pulling and restricted extension. Split-thickness skin graft (STSG) patches visible - hypopigmented, different texture to surrounding skin. Demonstrates the limitation of STSG in preventing recurrent digital contracture compared to FTSG.

Severe hand and forearm contracture (Grade III / complete functional loss)

Severe post-burn hand contracture with claw deformity, fixed finger flexion, thumb adduction, and electrical injury
Grade III / Kurtzman Grade III hand contracture following electrical burn. Complete non-functional claw-hand posture with severe finger flexion contractures, thumb adduction, and loss of all grasping function. Extensive hypertrophic scarring with mottled hypo/hyperpigmentation over forearm and palm. This is the end-stage of inadequately managed hand burns - requiring complex multi-stage reconstruction.

ELBOW CONTRACTURE

Moderate elbow flexion contracture

Post-burn elbow flexion contracture with antecubital hypertrophic scarring and mosaic skin texture
Moderate elbow flexion contracture. Antecubital fossa with thickened, pebbled/mosaic hypertrophic scar tissue and hyperpigmentation over the upper arm and forearm. A prior reconstructive scar is visible. Restricted elbow extension is evident from the posture of the limb.

Severe elbow contracture with perforator flap planning

Severe elbow contracture with trilobed perforator flap markings for contracture release
Severe elbow contracture with unstable scar and significant flexion deformity. Surgical markings for a trilobed perforator flap (three adjacent flaps labeled a > b > c) designed to release the contracture with rotation of local perforator-based tissue - an example of modern perforator flap planning for joint contracture.

Severe (90°) elbow contracture requiring free flap

Rigid 90-degree elbow flexion contracture before and after ALT free flap microsurgical reconstruction
Severe Grade III elbow contracture - fixed 90° flexion deformity (left image). After surgical release of scar, lacertus fibrosus, and biceps tendon lengthening, a 12x12 cm defect remains (center). Covered with a free ALT flap with limb shown in improved extension (right). This case illustrates the highest-grade joint contracture requiring microsurgical reconstruction.
