Abstract
The direct midlateral approach and the lateral enlarging procedure of the pulley system have been utilized in our service since 1972. The incision runs directly behind the neurovascular pedicle, which is left in the palmar skin flap of the anterior compartment of the finger, in order to ensure its blood supply and sensibility. The transverse digital lamina of Landsmeer’s skin anchoring system and Cleland’s ligament are preserved and are used to perform a lateral enlargement of the pulleys after tendon repair. The technique allows wide surgical exposure of the digital fibro-osseous tunnel, enlargement and reconstruction of the pulley system and tendon sheath, flexor tendon repair (using the technique of choice) and reduces postoperative impingement in zone 2.
