This diagnostic image is an anteroposterior (AP) X-ray of the thoracolumbar spine showing significant scoliotic deformity. The visual content demonstrates an automated Cobb angle measurement performed by clinical software. Green rectangular boxes are overlaid on individual vertebral bodies from the upper thoracic to the lower lumbar region, mapping their anatomical margins. A red polyline follows the central spinal midline, highlighting lateral curvature. Two sets of intersecting red tangent lines are visible: one in the upper thoracic region measuring an angle of 36.61 degrees, and another in the lumbar region measuring 23.26 degrees. These measurements identify a double-curve pattern consistent with combined thoracic and lumbar scoliosis. The vertebral bodies show visible rotation and tilting, particularly at the apex of the curves. The software tools illustrated are used for objective spinal deformity assessment and classification in orthopedic and radiological settings.

Anteroposterior (AP) X-ray radiograph of the thoracolumbar spine demonstrating a scoliotic curve with superimposed digital measurement aids. The image shows the spinal segment from T10 to S1, with each vertebral body explicitly labeled. A central blue vertical line indicates the coronal midline. Green solid lines are placed at the superior endplate of T11 and the inferior endplate of L5 to define the vertebrae for Cobb angle calculation. A dashed green line traces the lateral spinal curvature on the right side (dextroscoliosis), with a calculated Cobb angle of 33.8 degrees. Additional pink solid and dashed lines provide further alignment references at the T12 level. The image serves as a clinical evaluation of spinal deformity and demonstrates a potential technical outlier where the inferior endplate marker (green line) shows slight misalignment with the S1/L5 junction, highlighting the importance of precise vertebral endplate identification in automated software for scoliosis assessment.

This diagnostic image is a weight-bearing anteroposterior (AP) full-spine radiograph, commonly used for scoliosis evaluation. The X-ray demonstrates a long-segment scoliotic curvature of the spine with a dextroconvex (right-sided) orientation. Anatomical landmarks indicate the curve originates in the upper thoracic spine (T2) and extends through the thoracolumbar junction to the upper lumbar region (L2). Digital annotations show a Cobb angle measurement of 28.8 degrees for this primary curve. Additional quantitative markers include a 90.0-degree angle measurement at the pelvic/lower lumbar interface, evaluating coronal balance or pelvic tilt. The image is critical for diagnosing spinal deformities, assessing vertebral alignment, and monitoring progression in pediatric or adult orthopedic patients. It highlights the absence of significant pedicle rotation at the apex, which is a key clinical indicator in distinguishing between structural and compensatory or non-structural scoliotic curves secondary to conditions like spondylolisthesis.

This diagnostic imaging set consists of 15 anterior-posterior (AP) X-ray images of the human spine, showcasing various degrees of spinal curvature consistent with Adolescent Idiopathic Scoliosis (AIS). Each image features an automated Cobb angle measurement overlay generated by a convolutional neural network (CNN). The individual vertebrae from the thoracic to the lumbar region are demarcated by green bounding boxes. The Cobb angle is visually represented by two intersecting blue lines tangential to the superior and inferior endplates of the most tilted vertebrae in a curve, with the calculated angle displayed in red text. The images demonstrate diverse spinal morphologies, ranging from mild postural deviations to significant lateral curvatures. At the bottom left and right of each panel, numerical values represent independent evaluations from two human observers for clinical comparison. The collection illustrates the application of deep learning algorithms in orthopedic radiology for the automated detection, landmark localization, and quantification of spinal deformities.

This lateral lumbar spine X-ray demonstrates advanced degenerative changes and scoliotic deformity in a 56-year-old patient. Key findings include significant multilevel intervertebral disc space narrowing, particularly prominent in the mid-to-lower lumbar segments, indicating chronic disc degeneration. Extensive anterior and lateral osteophyte formation is visible along the margins of the vertebral bodies. There is evidence of facet joint arthropathy characterized by sclerosis and hypertrophy of the posterior elements. The spinal alignment shows a loss of normal lumbar lordosis and malalignment suggestive of degenerative scoliosis, with vertebral body rotation and tilting. The combined findings are consistent with multilevel central canal and neuroforaminal stenosis, typical of complex adult spinal deformity secondary to degenerative joint and disc disease. This imaging serves as an educational example of progressive spondylosis and its impact on sagittal spinal balance.

The image consists of two diagnostic views of the spine. Figure A is a posterior-anterior full-spine radiograph demonstrating severe degenerative scoliosis. A double curve pattern is visible, with a primary thoracic curvature quantified by a Cobb angle of 60 degrees (marked with red lines). A dashed white line across the shoulders indicates a significant shoulder and pelvic tilt, highlighting postural imbalance. Figure B is a sagittal T2-weighted MRI of the lumbar spine. It reveals multilevel degenerative disc disease and spondylolisthesis. At the L4-5 level, a white arrow points to a posterior disc bulge and ligamentum flavum hypertrophy, resulting in mild indentation of the thecal sac. Facet joint degeneration and osteophyte formation are also evident at the L2-3 level, contributing to mild spinal stenosis. The combined images illustrate the correlation between macroscopic spinal deformity (scoliosis) and localized structural pathology (spondylolisthesis and disc herniation) in a clinical context of chronic back pain.

A multi-modal radiological composite demonstrating multilevel lumbar disc degeneration (LDD) and spinal instability in a 58-year-old patient. The image series includes: (a) posteroanterior X-ray showing lumbar alignment; (b) lateral neutral X-ray; (c) hyperextension and (d) hyperflexion lateral X-rays illustrating dynamic instability at the L4/5 level through vertebral translation and angular changes. (e) Sagittal T2-weighted MRI highlights degenerative disc changes across L3/4, L4/5, and L5/S1, characterized by reduced disc height and signal intensity loss (desiccation). (f) Axial MRI provides detailed visualization of central canal stenosis and potential neural foraminal narrowing. (g) Axial CT scan emphasizes bony anatomy, revealing facet joint hypertrophy and osteophyte formation. The collection serves as an educational example of how different imaging modalities contribute to diagnosing complex spinal pathology, specifically highlighting the utility of dynamic X-rays for instability, MRI for soft tissue/disc assessment, and CT for osseous changes in the context of degenerative spine disease.

The images demonstrate three-dimensional postural corrections using specific therapeutic equipment. (a-f, h) utilize Swedish wall bars and poles for elongation and shoulder counter-traction. (b, c, i) show side-lying and prone positions on mats with supportive cushions for muscle cylinder and rotational respiration training. (g, j) demonstrate sitting and standing exercises using a Swiss ball to challenge core stability and pelvic alignment. Key anatomical focuses visible include the correction of thoracic and lumbar spinal asymmetry, pelvic tilt adjustment, and paraspinal muscle engagement. These exercises aim to treat idiopathic scoliosis by promoting spinal elongation, derotation, and lateral correction through specialized breathing and isometric tension techniques. The series illustrates the clinical application of Schroth principles including rotational respiration, sail exercises, sideways hangs, and gait training in a rehabilitative setting.

A clinical photograph in a physical therapy setting demonstrating the 'New Power Schroth' exercise for scoliosis management. The image shows a female patient in a kneeling or squatting position facing a wall bar apparatus. Her right arm is elevated and gripping a high bar to facilitate thoracic derotation and redression of a rib hump on the convex side of the spinal curve. A therapist is positioned behind the patient, using tactile cues with his hands on her lumbar region and lower back to monitor postural synergy and alignment. The patient is wearing a dark sports bra with a white measuring tape or band secured around the lower rib cage/waistline to monitor thoracic expansion or spinal correction. This illustration highlights the application of the Schroth method, a specialized physiotherapy approach used to improve pulmonary function, reduce pain, and halt curve progression in adolescent or adult idiopathic scoliosis through three-dimensional spinal correction.

Two clinical photographs demonstrating corrective physical therapy exercises for scoliosis management, specifically within the Schroth Best Practice approach. (a) Muscle Cylinder Exercise: A patient is shown in a standing position with the torso rotated. One leg is extended laterally toward a stall bar (wall ladder), and one hand is placed on the lumbar region to provide tactile feedback or support. This exercise aims to activate intrinsic back musculature and achieve multi-planar spinal correction (frontal, sagittal, and horizontal). (b) Hanging Exercise: The patient is seen from the posterior view, suspended from a stall bar with arms extended overhead. The knees are flexed and the body is aligned vertically. This modality focuses on spinal elongation and mobilization, particularly relevant for severe scoliotic curves where thoracic gibbosity is present. Both images serve as educational demonstrations of rehabilitation techniques used to modify the Angle of Trunk Rotation (ATR) and manage spinal curvature in orthopedic and physical therapy contexts.

Clinical photograph (posterior view) demonstrating a female patient with scoliosis performing the Schroth '50 x Pezziball' exercise. The image is split into two panels, (a) and (b), illustrating the principle of active 3D auto self-correction. In panel (a), the patient is seated in a neutral, relaxed position on a green Swiss ball (Pezziball) in front of a mirror and wall bar. Visible spinal asymmetry is present, with a right thoracic prominence and left lumbar indentation. In panel (b), the patient performs the corrective exercise by reaching upward and outward to grasp the horizontal rungs of the wall bar. This active engagement facilitates spinal elongation and derotation, aimed at shifting the trunk's convexities inward and expanding the concavities. The patient is wearing athletic attire and gloves for grip. This exercise is a key component of Physiotherapeutic Scoliosis-Specific Exercises (PSSE) designed to stabilize the spine and counter the 'vicious cycle' of curve progression through postural awareness and muscular activation.

A clinical photograph illustrating a patient performing spinal stabilization exercises according to the Lyon method for scoliosis management. The image shows a female patient in a side-lying posture on a blue exercise mat. She is supported by her right forearm and left hand, with her torso partially elevated to engage core and paraspinal musculature. Her hips and knees are flexed in a stable, stacked arrangement. A physical therapist is positioned behind the patient, providing supervision and tactile guidance to ensure correct spinal alignment and trunk positioning. The exercise focuses on active stabilization, proprioception, and the correction of scoliotic curves through muscle activation and postural awareness. The background features a plain wall and an inset image showing tree-like architectural structures, which likely serves as a visual aid or context for the Lyon school's setting. This material is designed for physical therapy education, specifically demonstrating Conservative Management of Spinal Deformities (CMSD) through Physiotherapy Scoliosis-Specific Exercises (PSSE).

Clinical photograph of a patient performing the 'Muscle-cylinder' exercise, a specialized physiotherapy technique for scoliosis correction. The patient is positioned in a side-lying posture on a yoga mat, resting on the lumbar convex side. A small support (rice bag) is placed under the lumbar convexity to assist horizontal spinal alignment. The upper leg is abducted and supported by a small stool, while the upper arm rests on a chair seat with the elbow flexed. Overlaid graphical elements illustrate biomechanical forces: light blue arrows indicate cranial and caudal trunk elongation; green half-moons mark concave areas targeted for expansion; red arrows denote muscle activation directing convexities toward the midline; and a dark blue arrow at the right elbow signifies lateral isometric shoulder traction with a fixed scapula. This therapeutic position is designed to promote 3D postural correction, segmental mobilization, and core stabilization specifically for major lumbar scoliosis curves.

A multi-panel clinical photograph series documenting postural adaptations and therapeutic management in adolescent idiopathic scoliosis (AIS). The images illustrate patients in various positions relevant to activities of daily living (ADLs), including standing, side-lying (supine/prone variants), and sitting. Visible clinical features of scoliosis include lateral spinal curvature, uneven shoulder height, and waistline asymmetry. Several frames demonstrate the use of asymmetric rigid spinal braces (such as the ARTbrace or Rigo-Chêneau type), highlighting how the orthosis provides external corrective forces to improve truncal alignment and thoracic symmetry during rest and activity. Lower panels specifically depict ergonomic modifications for ADLs: carrying a bag with proper weight distribution (highlighted with blue ellipses for pelvic/waist alignment) and performing tasks like bending, lifting, and reaching. The content emphasizes the integration of Physiotherapy Scoliosis-Specific Exercises (PSSE), such as the BSPTS or Schroth methods, aiming to correct 3D spinal deformities through active self-correction and postural awareness training.

This clinical photograph demonstrates a specific therapeutic positioning technique in the supine position for curve-specific correction, typically used in physical therapy for scoliosis or pelvic obliquity. The patient is lying supine on a padded examination couch. To address transverse and sagittal plane pelvic asymmetries, the left leg is crossed over the straight right leg, with the left hip and knee flexed and the left foot placed beside the right knee. This configuration aims to bring a posteriorly rotated left pelvis forward. The patient's upper body is stabilized with arms extended laterally; the right hand holds a cylindrical wooden dowel, likely used to facilitate thoracic stabilization or derotation during corrective exercises. This posture leverages the lower extremities as a lever arm to assist in lumbar and pelvic realignment. The image serves as an educational example of conservative rehabilitative management for spinal deformities and pelvic malalignment.

A clinical photograph depicting a manual therapy session in a rehabilitation or physiotherapy clinic. A patient is lying supine on a white adjustable treatment table while a therapist performs active myofascial relaxation. The therapist is positioned at the patient's side, manipulating the right lower extremity; the hip is flexed and the knee is extended, with the patient's foot resting near the therapist's shoulder to achieve a deep stretch. This technique is specifically targeted at the hamstrings and erector spinae muscles as part of a scoliosis treatment protocol. The clinical setting includes a large wall mirror reflecting similar therapeutic activities, suggesting a specialized facility for spinal correction and motor balance training. The educational focus is on normalizing tension along the Superficial Back Line (SBL) to address spinal deformities in the sagittal plane, such as flattened thoracic kyphosis or lumbar lordosis adjustments associated with adolescent idiopathic scoliosis.

A composite of six clinical photographs (a–f) demonstrating various Physiotherapeutic Scoliosis-Specific Exercises (PSSE) performed by a female patient with adolescent idiopathic scoliosis.

(c) Therapist-assisted rotary breathing training in a squatting position using a wall bar (ladder). (d) Active 3D correction while seated on a bench, utilizing a blue wedge pad under the left hemipelvis and an elastic resistance band held with abducted/externally rotated arms in front of a mirror. (e) Seated correction using two vertical wooden rods for stabilization, viewed from the rear. (f) Side profile of the seated correction holding a single vertical rod. The series illustrates core PSSE principles: 3D autocorrection, breathing techniques, and the use of corrective aids like wedges and poles to stabilize spinal curvature in the coronal, sagittal, and horizontal planes.

This composite educational graphic illustrates the design and biomechanical principles of a 3D corrective brace (based on Rigo principles) for early-onset single thoracic scoliosis. The left panel shows a clinical photograph of a pediatric patient wearing a rigid thoracic-lumbar-sacral orthosis (TLSO). The brace features specific expansion voids and pressure areas, including a regional derotation zone (marked with a red circle) and counter-rotation points (marked with yellow circles). The right panel provides a corresponding biomechanical diagram of the vertebral column with a left-convex thoracic curve. Large red arrows indicate the primary regional derotation mechanism acting at the apical region of the main curve, while yellow arrows demonstrate cranial (superior) and caudal (inferior) counter-rotation forces. The diagram highlights lateral, dorsal, and ventral contacts designed to optimize frontal and sagittal plane alignment. This visual demonstrates the multi-planar corrective strategy used in orthotic management to achieve spinal balance and prevent the progression of compensatory curvatures in scoliosis patients.

This composite educational graphic illustrates post-surgical lateral decompensation in Adolescent Idiopathic Scoliosis (AIS). On the left, a posterior-anterior (PA) diagnostic X-ray of the spine shows a lumbar curve stabilization using spinal fusion instrumentation, consisting of a longitudinal metal rod and multiple pedicle screws. Despite the lumbar fusion, a significant compensatory thoracic curve is visible, resulting in coronal imbalance. On the right, a corresponding posterior trunk surface topography diagram (line drawing) maps the external cosmetic deformity. The topographic lines demonstrate clear asymmetry: the right side of the upper torso is more prominent, while the left side of the lower torso projects further outward. This side-by-side comparison demonstrates the lack of correlation between internal radiographic correction of a single curve and the overall clinical/cosmetic balance of the trunk, highlighting the phenomenon where progression of an unfused curve leads to patient dissatisfaction due to persistent postural imbalance.

This set of three standing posteroanterior (PA) spinal radiographs demonstrates the surgical management and longitudinal follow-up of adolescent idiopathic scoliosis (AIS). Panel A (preoperative) shows a primary right-convex thoracic curve and a secondary left-convex lumbar curve, resulting in significant coronal imbalance and shoulder asymmetry. Panel B (immediate postoperative) shows the result of posterior spinal fusion using bilateral pedicle screw (PS) constructs extending from the upper thoracic to the lower thoracic/upper lumbar vertebrae. A horizontal line across the clavicles highlights the postoperative improvement in shoulder balance, although some residual tilt persists. Panel C (two-year follow-up) illustrates the long-term stability of the hardware and correction. A white arrow points to the 'distal adding-on' phenomenon, where a new curve develops immediately below the lowest instrumented vertebra (LIV). This compensatory mechanism is shown in relation to the achievement of a level shoulder balance, represented by the horizontal line being parallel to the top of the frame. These images serve as an educational example of thoracic curve correction, postoperative postural adaptation, and common radiographic phenomena following spinal instrumentation.

This lateral view X-ray radiography shows a pre-operative sagittal profile of the cervical, thoracic, and lumbar spine. The image reveals a significant thoracolumbar kyphosis, particularly pronounced at the high lumbar region. The normal lumbar lordosis is absent, replaced by a forward angulation of the spine. The vertebral bodies in the affected lumbar and thoracic segments demonstrate dysplastic changes characteristic of dysostosis multiplex, including anterior beaking and wedging, where the anterior height is significantly reduced compared to the posterior height. This structural abnormality leads to narrowed and irregular intervertebral spacing and global spinal malalignment. The bone density appears heterogenous with areas of radiolucency. This radiograph is a classic clinical example of spinal manifestations associated with Mucopolysaccharidosis Type 1 (MPS 1), illustrating the severe skeletal deformities that require orthopedic intervention to prevent neurological compromise and improve functional gait outcomes.

Full-body EOS imaging and corresponding 3D digital reconstructions of a 16-year-old female patient diagnosed with Adolescent Idiopathic Scoliosis (AIS). The image set includes coronal (anterior-posterior) and sagittal (lateral) views. The coronal view demonstrates a significant 'S'-shaped lateral spinal curvature characterized by a 67-degree Cobb angle. The primary thoracic curve exhibits a rightward convexity, while the lumbar region shows a compensatory leftward convexity, classified as Lenke 1AN. The 3D models highlight vertebral rotation, specifically shifting the spinous processes toward the concavity of the curves. In the sagittal view, there is a visible reduction in normal thoracic kyphosis and an altered lumbar lordosis, accompanied by a posterior pelvic tilt. These diagnostic images illustrate the complex three-dimensional deformity of the spine, showing the relationship between coronal malalignment, sagittal profile changes, and pelvic compensation in scoliosis management.

This medical illustration presents a three-dimensional anatomical diagram of the human spine demonstrating scoliosis across three standard orthogonal planes: coronal, sagittal, and axial. In the coronal plane, the spine shows a significant lateral 'S-shaped' curvature, deviating from the normal vertical midline. The sagittal plane view displays the anterior-posterior profile, illustrating alterations in the natural thoracic kyphosis and lumbar lordosis associated with the deformity. The axial plane view highlights the critical rotational component of scoliosis, where vertebral bodies and spinous processes are twisted relative to the longitudinal axis. This visualization serves as an educational tool for orthopedic and radiological study, emphasizing that scoliosis is a complex 3D deformity involving lateral displacement, rotation, and sagittal plane changes. The blue-colored 3D model facilitates the identification of vertebral alignment and the morphological changes used to calculate the Cobb angle for determining clinical severity.

Diagnostic sagittal Magnetic Resonance Imaging (MRI) of the spine, presented in three views (A, B, and C) highlighting degenerative and structural pathologies. Panel A shows a lateral view of the lumbar and sacral spine, demonstrating significant kyphosis and loss of normal lumbar lordosis. Red ovals in panels A and B delineate regions of multi-level vertebral body wedging, irregular endplates, and prominent osteophyte formation characteristic of Scheuermann disease. Panel C provides a focused view of the lower lumbar region where a red arrow points to significant spinal canal stenosis. Visible features include reduced intervertebral disc height, disc bulging, and ligamentous hypertrophy contributing to the narrowing of the neural canal. The imaging captures extensive degenerative disc disease across multiple vertebral levels, demonstrating the clinical progression of juvenile osteochondrosis into adult spinal deformity.

This composite image illustrates the conservative management of Scheuermann's kyphosis using a specialized spinal orthosis. The left panel consists of two lateral X-ray radiographs of the thoracic spine. The first X-ray demonstrates rigid thoracic kyphosis with characteristic vertebral wedging and increased sagittal curvature. The second X-ray shows the patient in a Kyphologic™ brace, exhibiting significant in-brace correction of the curvature (>20°) and improved vertebral alignment. The right panel contains two clinical photographs (posterolateral and posterior views) of a patient wearing the low-profile Kyphologic™ brace over a white T-shirt. The brace is a rigid thoracolumbosacral orthosis (TLSO) featuring a colorful geometric pattern, significant posterior cutouts for comfort and ventilation, and a side-closure mechanism using straps. The design employs a 3-point pressure system to redress thoracic hyperkyphosis while minimizing material bulk to improve patient compliance and quality of life.

Comparison of two lateral diagnostic X-ray images of the thoracic spine demonstrating significant hyperkyphosis. The left image shows a more severe sagittal plane deformity with a Cobb angle measurement of 94°, indicating a pronounced thoracic curvature. The right image shows a slightly improved but still abnormal kyphotic curvature measured at 80°. Both images utilize white anatomical landmarks and intersecting lines to illustrate the measurement of the thoracic kyphosis angle. The radiographs display the vertebral bodies of the thoracic and upper lumbar regions, highlighting the degree of anterior wedging or postural deviation contributing to the deformity. Clinically, such images are used in orthopedics and neurosurgery to assess the severity of spinal conditions like Scheuermann's disease, neuromuscular kyphosis, or compensatory changes related to spinal lesions or cysts. The visual comparison serves as an educational tool for monitoring disease progression or postoperative correction in pediatric or adolescent patients.

**Imaging Modality:** Lateral plain film radiograph (X-ray). **Anatomical Region:** Thoracolumbar spine, focusing on multiple contiguous vertebral bodies. **Observed Pathology:** The image demonstrates classic radiologic features of Scheuermann’s kyphosis. Key findings include: * **Vertebral Wedging:** Anterior shortening of the vertebral bodies, contributing to an increased thoracic kyphotic curvature. * **End-plate Irregularities:** Undulating and fragmented superior and inferior vertebral end-plates, indicated by the black arrow. * **Schmorl’s Nodes:** Intravertebral disc herniations visible as focal radiolucent indentations into the vertebral end-plates. * **Disc Space Narrowing:** Reduced intervertebral disc height in the affected segments. **Characteristic Visual Features:** The vertebrae exhibit a loss of the normal rectangular profile in favor of a wedged morphology. There is evidence of subchondral sclerosis adjacent to the irregular end-plates. **Clinical Context:** These structural changes are diagnostic of juvenile osteochondrosis of the spine (Scheuermann's disease), characterized by fixed hyperkyphosis and secondary degenerative changes of the spinal column.

This clinical photograph provides a lateral view of a male patient demonstrating severe sagittal plane spinal deformity characteristic of Scheuermann's disease (juvenile kyphosis). The image illustrates a pronounced, fixed angular thoracic kyphosis centered in the mid-to-upper back. Visible compensatory mechanisms include an exaggerated lumbar lordosis (increased inward curvature of the lower spine) and increased cervical lordosis. The patient's posture is marked by a forward head protrusion, often referred to as 'gooseneck' posture, where the head is positioned anterior to the vertical axis of the shoulders. The shoulders themselves appear rounded and anteriorly displaced. This visual representation serves as an educational example of significant spinal imbalance and the characteristic morphological changes associated with structural hyperkyphosis in the thoracic region. This content is relevant for orthopedic and physical therapy studies focusing on spinal pathology, postural assessment, and sagittal alignment disorders.

Diagnostic sagittal Magnetic Resonance Imaging (MRI) of the spine, presented in three views (A, B, and C) highlighting degenerative and structural pathologies. Panel A shows a lateral view of the lumbar and sacral spine, demonstrating significant kyphosis and loss of normal lumbar lordosis. Red ovals in panels A and B delineate regions of multi-level vertebral body wedging, irregular endplates, and prominent osteophyte formation characteristic of Scheuermann disease. Panel C provides a focused view of the lower lumbar region where a red arrow points to significant spinal canal stenosis. Visible features include reduced intervertebral disc height, disc bulging, and ligamentous hypertrophy contributing to the narrowing of the neural canal. The imaging captures extensive degenerative disc disease across multiple vertebral levels, demonstrating the clinical progression of juvenile osteochondrosis into adult spinal deformity.

This lateral-view spinal skiagram (X-ray) comparison demonstrates the preoperative and postoperative states of a severe thoracolumbar kyphotic deformity. (a) Preoperative image: Shows a high-grade, acute angular kyphosis of the dorsal spine. A wedge-shaped 'internal gibbus' is visible, formed by the anterior collapse and subsequent posterior protrusion of vertebral remnants into the spinal canal, leading to mechanical spinal stenosis. (b) Postoperative image: Displays the result of anterior decompression via gibbus excision. The sharp curvature is noticeably corrected, and an autogenous iliac bone graft is seen bridging the intervertebral gap to provide structural stability and promote arthrodesis. The alignment of the vertebral column is significantly improved compared to the preoperative state. The images illustrate surgical management for paraplegia resulting from healed spinal tuberculosis (Pott's disease) with secondary kyphosis.

Lateral view X-ray of the thoracolumbar spine demonstrating a severe reversal of physiological spinal curvature. The thoracic region exhibits an atypical inward concavity (lordosis), while the lumbar region shows a pronounced outward convexity (kyphosis), creating a large gibbus deformity in the lumbosacral junction. The vertebral bodies appear crowded and irregular, with visible loss of intervertebral disc space in the affected segments. These structural findings are clinically consistent with sequelae of spinal tuberculosis (Pott's disease), resulting in a 'kyphotic pelvis' and significant skeletal remodeling. The image illustrates advanced orthopedic pathology and its impact on sagittal alignment, often leading to restricted pulmonary function and obstetric complications such as obstructed labor.
