Endoscopic retrieval of retracted flexor tendons: An atraumatic technique.

Background: The repair of retracted flexor tendons is a challenging problem for hand surgeons. The tendon stump should be handled in an atraumatic manner because any microtrauma to the sheath and tendon can lead to poor functional outcomes.

Methods: Twenty-three patients with flexor zone 2 injuries and intraoperative finding of retracted tendons were randomly divided into two groups: endoscopic retrieval group and proximal incision group.
