Transradial Amputations
Optimally performed at the junction of mid and distal thirds of the shaft as amputations through distal 1/3 are less likely to heal if the circulation is compromised in any way due to the thin skin and limited subcutaneous tissue distally
- Amputations can be performed further distally, however, if the circulation is fully intact
Rotation and strength proportional to length retained
Retain at least 4cm of prox ulna for elbow flexion
- Can reattach biceps to proximal ulna to allow for prosthesis fitting
Utilise FDS flap over bone ends
Krukenberg Procedure
- Rarely performed
- Utilised in patients with bilateral upper limb amputations — especially those who are blind and/or in countries where patients can’t access prostheses
- Converts long forearm stump into pincer controlled from pronator teres
- Need sufficient bony length past the attachment of pronator teres and less than 70deg elbow contracture
- Success depends on strength of pronator teres, sensation of forearm and mobility of elbow and forearm at proximal radioulnar joint
- Most patients are able to perform basic functional tasks after the procedure
