Ninety-five cases (154 tendons) with the digital flexor tendon laceration were treated in our clinic from 1979 to 1984. Among these cases, there were 4 cases (4 tendons) of rupture after repairing of the tendon. All cases were adult. All tendons (one was in zone I, two in zone II, and one in zone III), were lacerated sharply and were repaired by the Tsuge's method (using a looped nylon suture) within 2 days after injury.Two tendons were ruptured during the period of the early motion therapy by the Kleinert's method, one during immobilization, and one after immobilization. Active flexion of the finger during the period of immobilization (2 cases), accidental powerful grasping (1 case), and passive extension of the finger (1 case), were the proximate causes of rupture.Loss of cooperation for the therapy on the side of the patient, and unadjustable cast were also to be considered as a cause, especially in the cases of early motion therapy.
