Transradial Amputation With Pedicled Pronator Quadratus Interposition and Advanced Neuroma-Prevention Techniques.

Transradial amputation is a reconstructive option for upper-extremity trauma, infection, malignancy, and ischemia. The possible postoperative complications include residual radioulnar impingement and the development of a painful neuroma. In this report, a pedicled pronator quadratus flap interposition between the distal radius and ulna has been described. Additionally, various techniques to mitigate the development of symptomatic neuromas have been described.
