How Tendon Transfers Restore Movement

Tendon transfers are a powerful orthopedic surgical technique used to restore movement and function in a joint when the original muscle or tendon responsible for that movement has been permanently damaged or paralyzed. The procedure works by rerouting a working muscle and its attached tendon to take over the job of a non-working one.

At Fox Valley Orthopedics, our dedicated orthopedic surgeons offer specialized procedures for patients with complex injuries or nerve damage. We focus on providing expert, devoted care to help you regain control and strength.

If you or a loved one is experiencing severe weakness or paralysis in a limb or if you are considering a procedure to restore movement, please schedule a consultation with our specialists. Call us today at (630) 584-1400 or request an appointment through our online form on the Contact Us page.

Understanding the Mechanics of a Tendon Transfer

To understand how a tendon transfer works, it helps to think of the body as a system of cables and levers. Muscles create movement by contracting, pulling on the attached tendons, which in turn move the bones across a joint. The need for a transfer arises when a muscle is paralyzed due to permanent nerve damage or when the tendon itself is severely or irreparably damaged by trauma or disease. When this happens, a crucial function, like lifting a wrist or straightening a finger, is lost.

The goal of the surgery is to find a healthy, working muscle—called the donor muscle—that can be spared. The donor muscle must be strong enough and able to contract sufficiently to create the full range of motion required for its new role. Additionally, losing its original function cannot create a new, significant disability.

The Surgical Steps: Rerouting for Function

The surgeon performs several careful steps to change the muscle's job:

1. Detach the Tendon: The working donor muscle's tendon is detached from its original insertion point (the bone it used to move).
2. Reroute and Attach: The tendon is meticulously rerouted—guided through surrounding tissues and across the dysfunctional joint—and then firmly reattached to a new bone insertion point. This new point is typically where the non-working tendon was initially anchored.
3. New Function: When the brain tells the donor muscle to contract (its old job), the pull is now directed to the new attachment point. This simple rerouting allows the working muscle to perform the lost movement successfully.

Recovery and Re-education: The Brain's Role

The surgery is only the first step; the second, equally crucial step is re-education, often done through physical therapy. This involves training your brain to use the transferred muscle in its new role.

First, the limb is immobilized in a cast or splint for several weeks. This protects the new tendon attachment, allowing it to heal firmly to the bone. Once healing allows, a physical therapist guides you through exercises. The main challenge is retraining your brain. When you try to lift your wrist, for example, your brain might initially send a signal meant for the muscle's original job.

Through specific exercises, repetition, and biofeedback, you gradually learn to activate the donor muscle to perform its new function consciously. This re-education process is intensive and can take several months, but it is essential for the procedure's success.
