[Surgical results of various injuries related to central slip in extensor tendon of the hand].

In this article the results of surgical repair in 41 cases with different degrees of the central tendon band injuries of hand were reported and the results were compared for different kinds of operation. In this series all patients with degree I injury (3 cases) achieved excellent result by direct repairing disrupted tendons. 25 cases with degree II injury were repaired using three different procedures, among which the method of splitting lateral bands with cross suture yielded better result. However, only 7 patients (47%) reached excellent and good result, The reason for that is due to attention paid insufficiently to key problems during operation. For degree III injury only 5 cases out of 13 attained excellent and good result by transplantation of free tendons. The main cause for that failure is that the operator misplaced the crossing point of the tendons.
