Extensor Tendon Repair and Reconstruction

Abstract

The purpose of this chapter is to review the anatomy and function of extensor tendons, the physiology of tendon healing, and general principles regarding common acute and chronic extensor tendon injuries. Acute injuries are classified according to the modified Verdan system and the presenting symptoms, physical exam findings, and treatment strategies are discussed by zone of injury. Common chronic extensor tendon injuries are discussed as they relate to the dorsal wrist's division into six discrete fibro-osseous compartments. Lastly, this chapter reviews the role of  operative vs non-operative management as well as the use of immobilization vs early protective motion in the post-operative setting. This review contains 7 figures, 1 table and 37 references. Keywords: extensor, tendon, repair, reconstruction, rehabilitation, tendonopathy, surgery, splint
