Clinical course: Stable. Wound healing satisfactorily. Neurovascular status of the left foot intact. No complications identified to date.

13. Further Treatment

a. Treatment Plan

Continue analgesia (oral and/or IV as needed)
Continue broad-spectrum antibiotics (given open/contaminated joint injury)
Continue proton pump inhibitor (for known GERD and NSAID use)
Wound care: daily dressing changes; suture removal when appropriate
Immobilization: maintain short-leg cast for 4-6 weeks
Physiotherapy/rehabilitation once cast is removed
Ongoing orthopaedic outpatient follow-up with repeat X-rays

b. Specific Treatment

Analgesia:

Paracetamol 1000 mg (10 mg/mL x 100 mL), IV infusion, three times daily (08:00, 16:00, 23:00)
Celecoxib (Beroxib) 200 mg, 1 tablet orally once daily (08:00)
Meloxicam (Brosiral) 10 mg/mL 1.5 mL, intramuscular injection, as required for breakthrough pain

Antibiotics:

Ceftazidime (Tenamyd) 1 g, IV, every 8 hours (08:00, 16:00, 23:00) - covering gram-negative organisms including Pseudomonas
Levofloxacin 500 mg/100 mL, IV infusion at 30 drops/min, once daily (08:00) - extended gram-negative and atypical coverage for open joint infection prophylaxis

Gastric Protection:

Esomeprazole 40 mg, 1 tablet orally once daily (08:00) - indicated for GERD comorbidity and NSAID gastroprotection

Wound Care:

Daily wound dressing changes with aseptic technique
Suture removal planned (wound length < 15 cm protocol)

Immobilization:

Short-leg cast to remain in place; non-weight-bearing left lower limb

Rationale for Treatment Selection: The use of dual antibiotic coverage (Ceftazidime + Levofloxacin) is justified by the open joint nature of the injury with intraoperative contamination risk - a single antibiotic would not provide adequate breadth of coverage for a penetrating joint wound. Surgical intervention (open reduction, debridement, ligament repair) was mandatory given the open dislocation with joint penetration; closed treatment alone would not eliminate contamination or address the structural ligamentous instability. Esomeprazole is continued given both a documented GERD history and concurrent NSAID use, which significantly increases the risk of gastrointestinal complications.

14. Prognosis

Short-term:

Risk of surgical site infection or septic arthritis is elevated given the open/penetrating nature of the joint injury and the intraoperative finding of capsular tear - the dual antibiotic regimen mitigates but does not eliminate this risk
Risk of wound dehiscence or delayed healing is low given the patient is otherwise healthy (no diabetes, no immunosuppression, normal BMI)
Ankle instability post-repair may persist until full ligamentous healing (6-12 weeks); re-dislocation risk while in cast is low
Neurovascular recovery: Left dorsalis pedis pulse was absent on admission but returned after reduction, suggesting transient vascular spasm rather than vessel transection - prognosis for full vascular recovery is good
The patient is expected to be independently ambulatory with crutches (non-weight-bearing) by discharge

Long-term:

With anatomical delta ligament repair and appropriate rehabilitation, restoration of ankle stability and function is expected in the majority of cases
Risk of post-traumatic ankle osteoarthritis exists given articular cartilage contusion identified intraoperatively; this may manifest as pain and stiffness over 5-10 years
Risk of chronic ankle instability if ligament repair stretches or fails during the healing period
Full return to physical/construction work activities is expected at approximately 3-6 months post-injury, subject to rehabilitation progress

15. Preventive Measures

Based on the above prognosis:

Infection prevention: Continue dual-antibiotic prophylaxis for the full prescribed course; perform strict aseptic wound dressing daily; monitor for signs of septic arthritis (increasing pain, warmth, fever, elevated CRP/ESR) - early washout and re-debridement if infection develops
Cast care and neurovascular monitoring: Daily assessment of left toe perfusion, sensation, and movement to detect early compartment syndrome or cast pressure sores; patient educated to report any increasing pain, numbness, or coldness in the left foot
Thromboprophylaxis: The patient is immobilized and has undergone lower limb surgery - consider low-molecular-weight heparin (LMWH) prophylaxis for DVT prevention during the immobilization period, particularly once transferred to a step-down setting
Rehabilitation planning: Early physiotherapy consultation for upper limb strengthening, non-weight-bearing mobilization, and ankle range-of-motion exercises to begin after cast removal to prevent stiffness and muscle atrophy
Post-traumatic arthritis prevention: Ensure anatomical reduction is maintained on follow-up X-rays; advise the patient on weight management and avoidance of high-impact activities during the healing phase to reduce cartilage loading
GERD management: Maintain proton pump inhibitor throughout NSAID course; avoid NSAIDs once pain is adequately controlled with paracetamol alone
Occupational safety: Advise the patient and employer regarding appropriate worksite safety measures and protective footwear to reduce the risk of repeat ankle injury upon return to construction work

16. Comments

Consistency of theoretical knowledge with the patient's actual clinical course:

Mechanism of Injury: The mechanism (entrapment/forced twisting at a construction site) is entirely consistent with the resulting ankle dislocation pattern. High-energy forced plantar flexion and rotation at the ankle produces the medial capsular tear and delta ligament rupture seen intraoperatively. This is a well-described injury pattern in occupational accidents.

Initial Management: Pre-hospital management was suboptimal in documentation - no immobilization splint was applied at the scene, and the patient was transported without a documented limb stabilization protocol. Theoretically, the injured limb should have been immobilized in a padded splint in the position found before transport to prevent additional neurovascular injury from ongoing displacement. However, in this case no worsening vascular injury resulted.

Closed Reduction Prior to Surgery: The emergency physician performed a closed reduction (traction-reduction) in the Emergency Department and achieved partial reduction with return of the dorsalis pedis pulse. This is the correct theoretical approach: vascular compromise from ankle dislocation is a time-sensitive emergency requiring urgent reduction, and an attempt at closed reduction should be made immediately without waiting for the operating theatre if vascular compromise is present.

Surgical Decision: Surgery was clearly indicated given the open joint nature of the injury (vet thuong thau khop) with confirmed capsular laceration and delta ligament rupture. Conservative management (casting alone) would be inadequate because: (1) the joint was contaminated and required irrigation and debridement; (2) the structural instability from complete delta ligament rupture required operative repair to restore joint stability and prevent chronic instability. The surgical approach taken is consistent with the standard management of open ankle dislocations.

Antibiotics: The use of Ceftazidime + Levofloxacin is appropriate for an open joint injury with potential polymicrobial contamination (including gram-negative and atypical organisms from the construction environment). This combination is more aggressive than the typical post-surgical antibiotic prophylaxis used for closed procedures, but is justified here by the contaminated open wound.

Postoperative Course: The stable postoperative course with progressive wound healing and intact neurovascular status is the expected trajectory following successful open reduction, debridement, and anatomical ligament repair in an otherwise healthy young patient. The absence of fever, signs of septic arthritis, or wound complications to date is consistent with appropriate surgical and antibiotic management.

Viva questions asked About this patient record

Based on the patient record we just completed, here are the likely viva questions an examiner would ask, organized by section, with model answers:

VIVA QUESTIONS - NGUYEN DUC LONG (Left Open Ankle Dislocation)

SECTION 1: MECHANISM & DIAGNOSIS

Q1. What is the mechanism of injury in this patient, and how does it explain the pattern of injury found?

A: The patient was caught in a rolling metal sheet at a construction site - this produces a high-energy forced twisting/compression load on the ankle. This type of forced supination or rotation causes the talus to displace relative to the mortise, tearing the medial capsule and delta ligament. The open wound results from the bone edge or the entrapment object lacerating the skin from within or outside, creating the penetrating joint wound.

Q2. On admission, the left dorsalis pedis pulse was absent. What is the significance of this, and what did you do about it?

A: Absent pulse in an ankle dislocation indicates vascular compromise - the displaced talus is compressing or kinking the dorsalis pedis or anterior tibial artery. This is a limb-threatening emergency requiring urgent reduction. The correct management is immediate closed reduction under analgesia/sedation - you do not wait for the operating theatre. In this patient, the ED physician performed traction-reduction, which restored the pulse. If the pulse had not returned after reduction, urgent vascular surgery consult would be required to rule out arterial injury.

Q3. The X-ray showed no fracture. Does this make the injury less serious?

A: No. A dislocation without fracture can still be a serious injury because:

The ankle joint relies heavily on ligamentous integrity - a complete delta ligament rupture causes gross instability
The open wound penetrating the joint creates risk of septic arthritis, which can destroy cartilage rapidly
Absent pulse on admission indicates significant vascular compromise
Intraoperative findings showed articular cartilage contusion, which carries long-term osteoarthritis risk regardless of fracture presence

Q4. How do you classify this injury?

A: This is a Gustilo-Anderson open joint injury (open dislocation with a ~1 cm wound - Type I or II). By ICD coding: T14.3 (open dislocation), S91 (open wound of ankle). The dislocation itself can be classified by the direction of talar displacement (lateral, posterior, or medial dislocation of the talus relative to the mortise). Ligamentously, this is a complete medial collateral (delta) ligament rupture.

SECTION 2: CLINICAL EXAMINATION

Q5. What signs on clinical examination tell you this is a dislocation and not a fracture?

Gross deformity of the ankle without crepitus
The talus is palpably displaced from the mortise
X-ray confirms no bony injury but visible joint space disruption
The mechanism (high-energy rotation/entrapment) can cause either, but the clinical picture of gross instability and soft tissue signs without bony tenderness point to dislocation

However, in practice the X-ray is required to definitively exclude fracture - you cannot distinguish reliably on clinical grounds alone.

Q6. What is the delta ligament, and why is its rupture important?

A: The delta (medial collateral) ligament is a strong, fan-shaped ligament on the medial side of the ankle. It has two layers:

Superficial: spans from the medial malleolus to the calcaneus, navicular, and talus
Deep: connects medial malleolus to the talus (most important for rotational stability)

Its rupture is important because:

It is the primary restraint against lateral talar shift and external rotation of the ankle
Without repair, the ankle remains grossly unstable and prone to re-dislocation
It is rarely torn in isolation - its rupture indicates a high-energy injury

Q7. How do you assess for compartment syndrome postoperatively?

A: The 6 P's:

Pain - severe, out of proportion to injury, worsened by passive stretch of the toes
Pressure - tense, woody feel of the compartment
Paraesthesia - numbness/tingling in the foot (nerve ischaemia)
Paralysis - inability to move toes (late sign)
Pallor - pale or mottled skin
Pulselessness - late and unreliable sign

Compartment pressure measurement >30 mmHg (or within 30 mmHg of diastolic BP) is the threshold for emergency fasciotomy. In this patient, SpO2 was 100% in the toes and movements were maintained, making compartment syndrome unlikely - but monitoring must continue.

SECTION 3: INVESTIGATIONS

Q8. Why were coagulation studies (PT, APTT) ordered for this patient?

A: Coagulation studies are part of the pre-operative workup - before any surgery, you need to ensure the patient has no coagulopathy that would cause excessive intraoperative bleeding. In this patient, PT (INR 0.96) and APTT (27.2 s) were both normal, confirming he is safe to proceed to surgery without correction.

Q9. The WBC was 10.43 x 10⁹/L (mildly elevated). How do you interpret this?

A: This is a mild reactive leukocytosis consistent with the acute traumatic stress response - the body releases cortisol and catecholamines after trauma, which demarginate neutrophils from vessel walls and transiently raise the WBC. This is not diagnostic of infection at this point, as the injury just occurred. Platelets were also mildly elevated (475), which is also a reactive phenomenon. If the WBC rises further postoperatively alongside fever and worsening wound signs, infection must be considered.

Q10. What imaging would you order for this injury and why?

AP and lateral ankle X-rays - to confirm dislocation direction and exclude fracture (mandatory, done in this case)
Mortise view X-ray - dedicated 15-20° internal rotation view to assess the ankle mortise for symmetry and talar shift
CT scan of ankle (if fracture suspected or post-reduction X-ray is unclear) - better delineates osteochondral injury
Doppler USS or CT angiography - if pulse does not return after reduction (to rule out vascular injury); not needed here as pulse returned
MRI - not typically needed acutely; useful later if chronic instability or ligament assessment is required post-healing

SECTION 4: TREATMENT

Q11. Why was surgery chosen over conservative management for this patient?

A: Three absolute indications for surgery existed:

Open/penetrating joint wound - the wound communicated with the joint cavity. Conservative management cannot decontaminate the joint; irrigation and debridement must be performed surgically to prevent septic arthritis
Complete delta ligament rupture - the ankle was described as "grossly unstable" intraoperatively. Non-operative treatment of a complete medial ligament rupture in an open dislocation carries high risk of chronic instability and re-dislocation
Capsular laceration - required direct repair to restore joint integrity

Conservative management (casting alone) would only be appropriate for a closed, stable, isolated dislocation that reduces anatomically and has no neurovascular compromise.

Q12. Why was a tourniquet used during surgery?

A: A left thigh tourniquet at 250 mmHg was applied to create a bloodless operative field. This allows better visualization of the joint structures (capsule, ligaments, cartilage, neurovascular anatomy), reduces operative time, and decreases blood loss. The tourniquet pressure used (250 mmHg) is appropriate - standard practice is approximately 100 mmHg above systolic BP or a fixed pressure of 250-300 mmHg for lower limb surgery.

Q13. Explain the choice of antibiotics - why two agents?

A: This was an open joint injury from a construction worksite - the contaminating organisms are likely to include:

Gram-positive cocci (Staphylococcus, Streptococcus) - from skin and environment
Gram-negative bacilli (E. coli, Klebsiella, Pseudomonas) - from soil and construction debris
Anaerobes - possible in crush/devitalized tissue

Ceftazidime (3rd-generation cephalosporin) covers gram-negative organisms including Pseudomonas aeruginosa, which is common in soil-contaminated wounds. Levofloxacin provides additional broad-spectrum gram-negative and atypical coverage, penetrates well into joint tissue, and provides complementary cover.

Single-agent therapy (e.g., first-generation cephalosporin alone) would be inadequate for a contaminated open joint from an outdoor/industrial setting.

Q14. How long should the ankle be immobilized in the cast?

A: For a ligamentous repair (no bony fixation):

Cast immobilization: 4-6 weeks non-weight-bearing to allow ligament healing (delta ligament heals in 6-8 weeks)
After cast removal: progressive weight-bearing with physiotherapy
Brace/ankle support for a further 6-12 weeks during rehabilitation
Return to sport/heavy work: 3-6 months depending on functional recovery
Full ligamentous maturation takes up to 12 months

SECTION 5: PROGNOSIS & COMPLICATIONS

Q15. What are the potential complications of this injury?

Early complications:

Septic arthritis (highest risk given open joint contamination)
Wound infection / dehiscence
Neurovascular compromise / compartment syndrome
Re-dislocation (before ligament healing)
DVT/PE (immobilized patient post-surgery)

Late complications:

Post-traumatic ankle osteoarthritis (from articular cartilage contusion)
Chronic ankle instability (if ligament repair fails or stretches)
Avascular necrosis of the talus (rare but serious - blood supply to talus may be disrupted by dislocation)
Stiffness and reduced range of motion
Malunion/subluxation of the ankle mortise

Q16. What is the most feared complication in this patient specifically, and why?

A: Septic arthritis is the most feared early complication. The joint was open and contaminated at the time of injury. Despite irrigation, debridement, and antibiotics, bacteria may establish within the joint. Septic arthritis causes rapid enzymatic destruction of articular cartilage (within 24-48 hours), leading to permanent joint damage and early severe osteoarthritis. Clinical warning signs include: fever, increasing joint pain despite cast, rising inflammatory markers (WBC, CRP, ESR), and purulent wound discharge. If suspected, urgent joint aspiration and culture followed by surgical washout is required.

Q17. What do you tell this patient about long-term outcomes?

The majority of patients with surgically repaired open ankle dislocations recover satisfactory function
He can expect to return to normal daily activities in 3-4 months
Return to construction work: approximately 4-6 months, with appropriate footwear
There is a moderate long-term risk of post-traumatic ankle arthritis given the articular cartilage injury - he may develop ankle pain and stiffness over 5-10 years
He should follow up with an orthopaedic surgeon annually after discharge
He should protect the ankle with a brace during strenuous activity for at least 12 months

QUICK-FIRE BONUS QUESTIONS

Question	Short Answer
What nerve is at risk in a medial ankle wound?	Tibial nerve (medial to tendons) and its branches
What artery supplies the talus?	Artery of tarsal canal (from posterior tibial) + dorsalis pedis branches - risk of AVN with dislocation
What is "trapping" in ankle dislocation?	Soft tissue (tendon/capsule) caught in the joint preventing reduction
What does SpO2 100% at the toes tell you?	Adequate peripheral oxygenation - no significant ischaemia at time of measurement
Why is GERD relevant here?	NSAIDs (Celecoxib) used for pain can worsen GERD - hence Esomeprazole is co-prescribed
When do you remove the cast?	4-6 weeks post-op for ligament repair; confirmed by X-ray
What rehabilitation exercises start first?	Isometric exercises and non-weight-bearing range-of-motion, then progressive weight-bearing

Good luck with your viva! The examiner will most likely focus hardest on why surgery was chosen, the absent pulse and its management, antibiotic rationale, and complication recognition.
