Abstract
In contrast to other zones of the hand, zone 1 flexor tendon injuries include laceration as well as avulsion mechanisms. Although zone 1 tendon lacerations are treated similarly to other zones, with various suture configurations and techniques, zone 1 avulsion injuries often require repair of tendon to bone. Proximity of the repair site to the distal interphalangeal joint often results in persistent flexion contracture and stiffness. Despite these differences in injury mechanism and location, zone 1 flexor tendon repairs are well tolerated and often lead to fair-high patient satisfaction.
