Question 1

In digital replantation, what is the recommended sequence for structural repair?

Accepted Answer

Bone fixation → Tendons → Arteries → Veins → Nerves

Answer

The standard replantation sequence is bone shortening/fixation, extensor then flexor tendon repair, arterial anastomosis, venous anastomosis, nerve repair, and skin closure to minimize ischemia time and allow stable structural repair before revascularization.
