Extensor Tendon Injuries

Extensor tendons are located on the back of the hand and straighten the fingers and thumbs. These tendons are attached to the forearm, are joined to the fingers by smaller tendons from the hand muscles. These all account for hand coordination. Tendons are vulnerable to injury because of their location on the back of the hands.


Most of these injuries, such as torn tendons, are treated and stabilized with a splint; however, cut tendons should be repaired surgically. A pin may be placed through the bone to serve as an internal splint. Incorrect positioning or non-compliance to doctor’s instructions can cause further problems. It is imperative to follow our Jackson, MS tendon injury treatment specialist’s directions for maximum improvement. Different things can affect outcome of extensor tendon injuries. These include nature and severity of the injury, fracture, infection and individual healing. Scar tissue may form and complicate finger bending and straightening. Therapy may resolve these type problems, or surgery may become necessary. Your Face & Body Center surgeon can determine the best method of treatment.

Flexor Tendon Injuries

Flexor tendons are located on the palmar side of the hand. Their function is to bend the fingers and wrist.

Injuries on the palm side of the wrist, hand and fingers may damage flexor tendons, connecting nerves and blood vessels. If both tendons are cut, fingers cannot bend on their own. If tendons aren’t cut through completely, fingers will still bend, but there will be pain and fingers may “catch” in motion. A cut tendon usually will not heal without surgery, but if cut ends are brought back together, healing can occur.


There are a variety of methods in tendon repair, and only a qualified hand surgeon can determine the appropriate treatment of a tendon injury. Movement may be restricted after surgery, or therapy may be started immediately. Scar tissue may affect bending and straightening or make additional surgery necessary. Following a physician’s instruction is imperative to a successful outcome.
