Question

The first structure to be fixed after amputation (during replantation) is?

• A. Bone fixing
• B. Arterial repair
• C. Venous repair
• D. Nerve repair

Hint:

You need a stable, correctly-lengthened scaffold before any microsurgical repair.

Answer 1

The Correct Option is A

Step 1: Recall the goal of replantation after a traumatic amputation. The aim is restoration of useful function, not merely re-establishing blood flow.
Step 2: Recall the fixed sequence of replantation. Once a part is deemed replantable, the procedure follows a set order so that the stable framework is created before the delicate microvascular work.
Step 3: The very first step is bone fixation (osteosynthesis). The bone is shortened and stabilised, most commonly with K-wires. This provides a rigid, length-matched scaffold on which all the soft tissues can be repaired.
Step 4: Follow the rest of the order: after bone fixation, the extensor and flexor tendons are repaired, then the microsurgical repair of the artery, followed by nerve repair, then vein repair, and finally skin closure and splinting.
Step 5: Because bone gives the structural foundation and correct length needed before vessels, nerves, and tendons can be repaired under tension-free conditions, bone fixation must come first.
Answer: Bone fixing (option A). This matches the printed key.
