The Krukenberg procedure is an amputation-related reconstructive option performed on the forearm. Its main indication and benefit are best described as:
- A Lengthening a short below-elbow stump to improve cosmetic appearance
- B Restoring pronation and supination in a stiff elbow
- C Creating a sensate pincer between radius and ulna sides, useful in blind bilateral amputees ✓
- D Improving the fit of a myoelectric prosthetic terminal device
Correct answer: C. Creating a sensate pincer between radius and ulna sides, useful in blind bilateral amputees
Explanation
The Krukenberg operation separates the forearm into radial and ulnar rays that act as a forceps with intact tactile sensation. It is classically indicated in blind patients with bilateral below-elbow amputations, because vision cannot substitute for lost touch in using a conventional prosthesis. Cosmesis is actually poor, which rules out option A, and the elbow itself is left undisturbed.
