Tendon Transfer Treatment & Surgery

There are over forty muscles below the elbow. Each muscle has its own specific function. For example, there are nine different muscles that control the thumb. Each muscle has its own origin and tapers down from its muscle belly into a tendon. Each tendon, a strong cord, is attached to a specific place on a bone. When the muscle contracts it causes motion by moving the tendon and the bone. A tendon crossing a joint transmits muscle movement into joint movement. When the muscle is injured or paralyzed and no longer functions, tendon transfer surgery is most likely needed.

  • Conditions Treated with Tendon Transfer Surgery
  • Nerve injuries – Sometimes muscle function is lost due to a nerve injury. When a nerve is injured and incapable of functioning, it fails to send signals to certain muscles. Those muscles are therefore paralyzed and lose all functionality.
  • Ruptured or lacerated tendons or muscles – Rheumatoid arthritis and fractures are two common conditions that cause a tendon to rupture. Lacerations are caused by direct injury, such as a cut from a piece of broken glass. In this case if direct repair can not be done tendon transfer surgery becomes necessary.
  • Rheumatoid arthritis – In rheumatoid arthritis, tendons in the hand may rupture due to severe inflammation of the tendon sheath around the tendon and the rubbing of the tendon on diseased bony prominence.
  • Nervous system disorders – Certain disorders of the nervous system such as cerebral palsy, spinal muscle atrophy and traumatic brain injury can hinder muscle function by preventing normal nerve signals from being sent to the corresponding muscle. 
  • Birth defects – In some instances, babies are born without certain muscle functions. Hypoplastic (underdeveloped) thumbs and birth brachial plexopathy (nerve problems with paralysis) are examples of congenital conditions that can be repaired with tendon transfer surgery.

Tendon Transfer Surgery

Tendon Transfer Surgery is a procedure performed to restore motor skills and function in the hand. The hand surgeon replaces or connects a diseased or inactive tendon with a healthy tendon.  During tendon transfer surgery, the origin of the muscle and its own nerve and blood supply are all left in place. The tendon is detached from its bone and re-sewn onto a different area. It can either be sewn onto a different bone or onto a different tendon which need motor function. When the muscle contracts, a new action will be produced, depending on where the tendon has been inserted. Tendon transfer surgery can restore many lost functions of the hand. After the surgery, the patient should regain the ability to straighten and bend the elbow and wrist, and the ability to grip with the fingers and hand.
