Abstract

Chronic rupture of the ulnar collateral ligament of the thumb is a complex lesion that typically results in chronic joint instability, functional limitation in pinch, and persistent pain at the metacarpophalangeal (MCP) joint of the thumb. Different surgical techniques have been proposed, including tendon graft and transpositions. In this article, we report our experience in treating chronic ulnar collateral ligament injuries using extensor pollicis brevis tendon in a Sakellarides modified technique. During the surgical procedure, we detach the extensor pollicis brevis proximally and drive the tendon through the neck of the first metacarpal and the base of the proximal phalanx to reconstruct the ligament at the ulnar side. In our experience, the surgical technique provides good MCP joint strength and stability and allows a good functional recovery with few postoperative complications. This technique provides good stability of the MCP joint using an absorbable suture and allows early mobilization of the joint with minimal stiffness.
