Abstract
Extensor tendon rupture is well known complication following distal radius fracture after either conservative treatment or volar plating. However, there are not many reports in literature about concomitant ruptures of other extensor tendons. We report a case of delayed rupture of extensor pollicis longus (EPL), second extensor digitorum communis (EDC II), and extensor indicis proprius (EIP) tendons 4 weeks after volar plating for distal radius fracture. Due to the absence of EIP, EIP transfer was discouraged for EPL reconstruction. Thumb and index finger extension was restored by palmaris longus tendon graft for EPL and EDC II.

Axial and three-dimensional computed tomography images demonstrating a fracture of Lister’s tubercle on the right side (arrows). A bony spur created a the gap between the fragment and the main radius part and might be the cause for tear of the tendon.

Preoperative and postoperative plain radiography showed that the fracture gap of the Lister’s tubercle persisted.

After removing the bony protrusion, the surrounding soft tissue was pulled to the ulnar side and sutured to the remaining tendon sheath and periosteum of the 3rd compartment to prevent further tendon tear (solid arrow).
