What is the technique for proximal forearm amputation for ulnar neuropathy?
What is the optimal site for wound healing after forearm amputation?
- A good compromise between adequate functional length and adequate wound healing appears to be at the junction of the distal and middle third of the forearm. Despite resection of the distal radioulnar joint, some degree of pronation and supination is preserved in persons with forearm amputations.
What is the Order of disarticulation in amputation?
- In ascending order, there is trans-phalangeal, trans-metacarpal, trans-carpal, wrist disarticulation, trans-radial, elbow disarticulation, trans-humeral, shoulder disarticulation, and forequarter amputation. Trans-phalangeal accounts for 78% of all upper extremity amputations.
Why are wrist disarticulation prostheses not used for transcarpal amputation?
- Because of their length, conventional wrist units are not used, and myoelectric fitting is problematic, as in persons with transcarpal amputations. However, current wrist disarticulation prostheses can be fashioned with thin wrist units that minimize the length discrepancy between upper extremities.
