Carpal Realignment Using a Strip of Extensor Carpi Radialis Longus Tendon.

Abstract

Scapholunate instability can lead to posttraumatic dysfunction of the wrist. If unrecognized, it commonly leads to degenerative osteoarthritis. Numerous reparative techniques have been proposed with mixed long-term success. We present a technique that uses a distally based strip of the extensor carpi radialis longus to better maintain reduction of the scaphoid and reconstruct the volar and dorsal scapholunate ligament and the scaphotrapezium-trapezoid ligament. To illustrate the technique, we describe a clinical case with 17 months of follow-up.
