  • Sometimes, a muscle forms improperly or shortens from remaining stationary in a contracted position for too long. If other treatments fail to solve the problem, the tenotomy is the weapon of choice in the orthopedic surgeon's arsenal.

    Purpose

    A tenotomy is a procedure designed to lengthen muscles that are improperly formed, have shortened or are resistant to stretching. This includes, but isn't limited to, hamstrings.

    Procedure

    The tendon is cut either entirely or part way through, allowing the muscle in question to stretch. Depending on the tendon to be cut, either a percutaneous tenotomy, which is performed through the skin under local anesthesia, or an open tenotomy, which surgically exposes the tendon under general anesthesia, may be performed.

    After the Procedure

    After a tenotomy, the limb receiving the surgery has a cast applied after the contracted muscle is stretched to its normal extension. The cast holds the muscle in place while the cut tendon regrows at its new, extended length. Braces or splints may also be applied as necessary and pain medication administered.

    Risks

    Tenotomy procedures have a small risk of excessive bleeding or infection. If general anesthesia is used during the procedure, all risks associated with general anesthesia apply.

    Results

    If the procedure is successful, the joint will have a better range of motion with a stretched muscle. The ability to stand, walk, stretch and perform other tasks may be improved, as well as a reduction in pain.
