Park, Huh, and Jung: Delayed Rupture of the Extensor Pollicis Longus Tendon Following Intramedullary Nailing of Radial Shaft Fracture

Abstract

Delayed rupture of the extensor pollicis longus tendon mostly occur after plate fixation of distal radius fracture. However, delayed rupture of the extensor pollcis longus tendon following intramedullary nailing of radial shaft fracture is very rare. We report one case of delayed rupture of the extensor pollicis longus tendon following intramedullary nailing, presenting abnormal signs from adhesion of the extensor pollicis longus with extensor indicis at the nail insertion site.
