The Fang is used to hold flexor tendons during tendon repair. Some instruments used in flexor tendon repair “crush” the tendon and can lead to stimulation of the scar response and subsequent adhesion formation, while other instruments that transfix the tendon, may not adequately immobilize the tendon ends to be sutured, and make for a difficult and potential traumatic repair. The Fang transfixes the tendon close to the cut ends via two needle size teeth directed in an anterior to posterior direction.
This is done without crushing the tendon or stimulating the epitenon and allows well controlled passage of suture into the tendon end, a variety of different suture techniques can be utilized. A stop prevents the fang from closing on the tendon, and contacting the epitenon and essentially allows for a “touch-less” technique.
