Flexor tendon suture: a description of two core suture techniques and the Silfverskiöld epitendinous suture.

: Flexor tendon injuries are commonly treated by orthopedic, plastic, and hand surgeons. Bunnell referred to zone 2 injuries as being in "no-man's land," plagued by poor results after surgical repair. Over the last 30 years, a better understanding of the biology of flexor tendon injuries, advanced surgical techniques, and perhaps most important, improved rehabilitation protocols, have afforded consistently good to excellent results after surgical repair at all levels of injury. Complications such as restrictive adhesions, joint contracture, and repair rupture, although less frequent, can compromise functional recovery.
