Extensor Tendon Centralization at the Metacarpophalangeal Joint: Surgical Technique

Pdf Summary

This document presents a surgical technique for the treatment of extensor tendon injuries at the metacarpophalangeal (MCP) joint. Extensor tendon injuries can result in instability and subluxation of the tendon, causing pain, weakness, and snapping. Surgical treatment may be necessary when conservative methods fail. Several surgical techniques have been used in the past, including tendon realignment using local tissue or nearby tendon slips and soft tissue release and imbrication. However, this technique presents a new approach that creates a bone tunnel for a graft that is sutured upon itself, effectively creating a new pulley. This technique offers the advantage of reconstruction without altering the surrounding soft tissue anatomy, potentially allowing for earlier postoperative motion. The document also provides information on the surgical anatomy of the extensor hood and the indications, contraindications, and postoperative care and rehabilitation for this surgical technique. The technique has shown effectiveness in treating extensor tendon injuries, and potential complications include failure of reconstruction, stiffness, and infection.
