Slip-knot flexor tendon suture in Zone II allowing immediate mobilisation.

Immediate mobilisation after flexor tendon suture produces a conflict between the muscle force and resistance of the sutures. Sutures within the tendon after repair are weak and need contrived measures (e.g. wrist and metacarpophalangeal flexion, rubber bands etc.) to prevent dehiscence, while pull-out sutures do not allow mobilisation because of their anchorage. A new technique is presented which consists of a simple slip-knot suture which transmits the tension generated by the muscle to the distal tendon stump and its bony insertion, allowing immediate mobilisation. Results in ninety eight cases repaired by this technique during nine years are presented.
