Extensor Tendon Repair

Abstract

Because of their location on the dorsum of the hand, the extensor tendons are particularly vulnerable to injury. This is even more likely over the joints since the dorsal skin is particularly thin there. Injuries can occur from both sharp and blunt trauma. Untreated extensor tendon injuries can result in significant functional impairment and potential long-term permanent deformities of the hand. There are significant differences in treatment for extensor tendon injuries involving the finger zones versus the hand. This chapter will describe the most common treatment modalities for extensor tendon injuries to the hand and forearm.
