A 28-year-old labourer has bilateral transradial amputations following an electrical burn injury and is also blind. Which surgical option is specifically designed to give him a sensate prehensile 'pincer' using his own residual forearm bones?
- A Boyd amputation
- B Gritti-Stokes amputation
- C Krukenberg procedure ✓
- D Syme amputation
Correct answer: C. Krukenberg procedure
Explanation
The Krukenberg procedure separates the radius and ulna into two mobile rays covered by skin and muscle, creating a sensate forceps-like pincer. Because it preserves tactile feedback between the rays, it is classically indicated in blind patients with bilateral transradial amputations who cannot rely on vision to position a conventional prosthesis. The other options are lower-limb amputation levels and are irrelevant here.
