Flexor Tendon Surgery

http://www.handandwristinstitute.com/... The tendons that allow you to flex your fingers are known, appropriately enough, as flexor tendons. They start in the forearm and travel through the carpal tunnel, over the palm, and into the fingers. The two flexor tendons in each finger anchor at different places, one at the middle joint, or PIP joint, and the other at the finger tip. On the way, they pass through pulleys, or tissue bands that hold them in place. The most common injury to a flexor tendon is a laceration, which can be from a knife, or due to an industrial injury. Typically, structures such as nerves and blood vessels are also affected by injuries to these tendons. Because they are held in tension, when tendons are cut, the two disconnected ends retract into their respective sheathes, and so must be fished out in order to be rejoined with surgery. Jersey finger is also a common injury to the flexor tendon, caused when the hand grasps an object such as a sports jersey, causing the tendon to tear away from the tip of the finger. The surgery to rejoin lacerated tendons is a complicated one, wherein the two edges are physically brought together and then sewn into place with an elaborate weaving stitch, referred to as the core suture because most of the body of the suture lies within the tendon itself. The joint is then strengthened with a finer suture, so that it can move easily in its sheathe after surgery. After surgery, the patient is splinted for a few days, after which a very rigorous regimen of therapy is begun. Because of the delicate nature of the injury and tendons, you must be careful to keep up with this therapy, or full mobility may not return. It will begin with passive, then active range of motion activities to ensure full function of the finger without stressing it too much. This will continue for several weeks, culminating in a full recovery period of approximately three months, or twelve weeks.
