Tendon transfer surgery is a surgery to restore the lost functions of the hand by shifting functioning tendon from its initial attachment to the new one.
During a tendon transfer surgical procedure, the muscle’s origin, its nerve supply and blood supply is kept intact but the tendon is detached from its place of insertion (attachment) on the bone and sutured back into a different bone or tendon. After the tendon is transferred, when a muscle contracts it will produce a new action depending on its place of insertion.
Usually, a tendon transfer surgery will require a period of 1-2 months to heal completely. During this time, a splint or cast will be given following which you will be taught about the new tendon function. After the tendon transfer has healed, your surgeon may recommend exercises to strengthen the muscle. It is important to take care that you do not start movements too early as it may cause rupture of the tendon transfer and at the same time do not delay the movements. Delayed movement can lead to scarring of the tendon and stiffness.
