Written Examination: Core Knowledge and Question Technique
What the written exam tests
The written paper rewards breadth with precision: you must move fluently between congenital, traumatic, reconstructive, aesthetic, and oncologic topics, and between anatomy, physiology, and operative planning. Anchor your revision in the concepts that recur across specialties: blood supply and angiosome-based flap design, the reconstructive ladder and its modern equivalent (reconstructive elevator), wound healing phases and the factors that arrest them, soft-tissue biomechanics and suture selection, and the classification systems examiners love (burn depth, nerve injury, fracture patterns, breast ptosis, cleft anatomy).
Traps that cost marks
Questions are usually written so that one distractor is almost right. Watch for:
- Absolute words ("always", "never") in options - usually wrong in surgery.
- Timing questions: when to debride, when to graft, when to remove drains, when to allow return to sport.
- Units and thresholds: resuscitation volumes, transfusion triggers, antibiotic durations, compartment pressures.
- Anatomy distractors: pedicle origin versus destination, nerve root versus peripheral nerve, dominant versus minor supply.
- Next-best-step questions: the answer is often the safest stabilizing step, not the definitive operation.
Worked rule of thumb
For any reconstructive scenario, first define the defect (size, depth, exposed vital structures, contamination, irradiated bed), then the patient (comorbidity, donor site availability, goals), then the option that satisfies both with the lowest aggregate morbidity. If an option requires a free flap in an unstable patient, it is usually the wrong answer even if technically elegant.
Exam technique
Answer every question; flag uncertain items and return. Read the stem twice for negatives. Use elimination on mechanistic grounds rather than memory alone - if you understand why a distractor fails physiologically, you rarely need to recall the exact fact.
