Differential Diagnosis Compare venous, arterial, diabetic, neuropathic, vasculitic, traumatic, infective, pressure, and malignant ulcers using detailed comparison tables. ⸻ 9. Case Presentation Provide a polished 5-minute university-style long-case presentation. ⸻ 10. Investigations Discuss: * CBC * ESR/CRP * Blood glucose/HbA1c * Wound swab (when appropriate) * Tissue culture * Biopsy * X-ray * Duplex Doppler * ABI/TBI * CT angiography * MR angiography * Digital subtraction angiography * MRI for osteomyelitis * Histopathology Include investigation algorithms and representative images. ⸻ 11. Management Provide evidence-based algorithms covering: * Initial wound assessment (TIME framework) * Debridement * Infection control * Moist wound healing * Compression therapy * Offloading * Revascularization * Antibiotic therapy * Skin grafting * Flap reconstruction * Negative Pressure Wound Therapy (NPWT) * Hyperbaric oxygen therapy (indications) * Amputation (indications and levels) * Follow-up and prevention of recurrence Compare recommendations from Bailey & Love, Sabiston, and current guidelines where relevant. ⸻ 12. Operative Discussion Discuss: * Split-thickness skin graft (SSG) * Full-thickness skin graft (FTSG) * Local flaps * Regional flaps * Debridement * Fasciotomy (where indicated) * Venous surgery * Endovascular procedures * Bypass surgery * Minor amputations * Major amputations For each procedure include: * Indications * Contraindications * Patient positioning * Operative steps * Key anatomy * Instruments * Complications * Prevention Include operative diagrams and standard textbook illustrations. ⸻ 13. Complications Discuss: * Cellulitis * Osteomyelitis * Sepsis * Hemorrhage * Gangrene * Malignant transformation (Marjolin ulcer) * Recurrence * Chronic pain * Limb loss Provide management flowcharts. ⸻ 14. Complete Viva Section Include: * 100+ examiner questions with model answers * Cross-question chains * Spot diagnosis * Instrument viva * Dressing viva * Image-based viva * Operative viva * Emergency scenarios * Ward-round discussion ⸻ 15. Image-Based Discussion Include authentic textbook or guideline images of: * Different ulcer types * CEAP staging * Wagner grading * WIfI classification * Clinical examination * Duplex Doppler * Angiography * ABI measurement * NPWT * Skin grafting * Flaps * Surgical instruments * Histopathology Do not use AI-generated images.
