Disruptions of the extensor mechanism.

Abstract

Extensor mechanism injuries represent a challenging problem for the orthopedic surgeon. Accurate diagnosis is essential because the best results are obtained with early diagnosis and treatment. Numerous techniques have been described for both early and late repairs. The choice of repair is dependent on the location of the tear, the time interval between injury and repair, and the degree of secondary contractures. Despite these difficulties, satisfactory results can be achieved.
