Retrieval of the retracted flexor tendons for long fingers: New tip.

Zone II flexor tendon injuries continue to be a challenge for hand surgeons. During the injury event, the tendon ends may retract towards the palm. Retrieval of these lacerated ends can be problematic because the tendon sheath is unstretchable. This demanding surgery requires a precise repair technique where the tendon stumps are handled in an atraumatic manner. Microtrauma to the tendon sheath must be avoided as this can induce adhesions and lead to poor functional outcomes. Several retrieval methods for retracted tendon ends have been described in published studies. In this technical note, we will describe a technical variation that streamlines the surgical procedure and uses commonly available materials. This simple trick makes the procedure easier and avoids having to suture the tendon to the tubing.
