    Tendon Transfer Surgery Can Restore Function in Hands, Wrists and Arms for People with Tetraplegia elbow flexor muscles, the brachioradialis, can be detached from one of the forearm bones, and then reattached into a thumb flexor muscle, restoring thumb pinch where there was not any before, Dr. Peljovich explains. get a book without help.

    suboptimal tendon transfer due to stiff joints selection of suboptimal or weak muscle-tendon unit for transfer incorrect vector of pull rupture of transferred tendon place the thumb into opposition with the small finger 2. Suture tendon. suture the FDS tendons to the thumb with a or braided polyester suture. The repaired tendon will usually be back to full strength after about 12 weeks, but it can take up to 6 months to regain the full range of movement. In some cases, it may never be possible to move the affected finger or thumb as much as before it was damaged. In general, most people are able to.

      An example of this is the extensor indicis proprius (EIP) transfer to restore thumb opposition in either a high or low median nerve palsy. By being transferred around the ulnar side of the wrist, the line of pull is directed to restore thumb opposition as the tendon is transferred into the abductor pollicis brevis insertion. Thumb Tendon Repair Recovery Process. In order to allow the tendon to fully recover, it will require a brief period of immobilization. This is usually followed by a carefully structured therapy program that lasts about 10 to 12 weeks in order to rehabilitate the tendon properly. It’s important to find a balance between moving too much and not.

Sincemany methods of tendon transfer have been described for the restoration of thumb opposition, all of which bring about an improvement of the grasp function, albeit to different degrees. These methods vary in the selection of the motor, the direction of pull of the tendon, the use of a fulcrum, and the mode of insertion.

[J M Ramselaar] -- In man and some of the apes, the thumb has the function of a contra­ finger. This function is made possible by a great freedom of movement of the first metacarpal and a highly developed and.

There are two commonly utilized tendon transfers to augment thumb function and strength in opposition, the Huber opposition transfer () and the flexor digitorum superficialis (FDS) opposition transfer ().

Both techniques are effective in improving thumb function and each has specific advantages. Background. There is paucity of literature on early tendon transfer in surgical rehabilitation of hands with median nerve injuries.

Since the single most important functional deficit in median nerve palsy is the loss of thumb opposition, we evaluated the results of early tendon transfer in restoration of thumb opposition. Although the use of the palmaris longus (PL) for restoring thumb opposition was first described by Bunnell, it was popularized by Camitz.

23 Although the PL transfer effectively restores palmar abduction, the pronation and flexion components of opposition are not re-established. The primary indication for performing a Camitz transfer is to. A tendon transfer is a surgery that moves a working muscle and tendon to replace a non-working muscle and tendon.

For example, after a broken wrist, the tendon to the thumb (EPL tendon) that allows you to make a “thumbs-up” can break. Often, the two ends of the tendon are very damaged and cannot be sewn back together.

Methods and material To effectively study the concept of tendon transfers to restore thumb opposition, three interrelated experi­ments were performed: (1) anatomic study of the me­chanical function of thumb muscles, (2) quantitative measurement of hand and forearm muscle volume, mean fiber length, and cross-sectional area, and (3.

For a useful grasp function of the hand it must be possible for the thumb to be placed opposite the middle finger with an abduction distance (page 15) of at least cm.

In about 30 per cent of the isolated lesions of the median nerve this position is not reached, and an opposition reconstruction should be considered (Kirklin and Thomas, ).

Many tendon transfers have been shown to restore opposition to the thumb and provide thumb and finger flexion. In order to have optimal results the individual needs to follow the following principles of tendon transfer: normal tissue equilibrium, movable joints, and a scar-free bed.

Doctors perform tendon repair surgery to fix a tendon injury. Tendons are tough, stretchy tissues that join muscles to bone. Their job is to allow the body to move and to transfer. restore thumb opposition.1,2 In term of longevity, it is the longest performed opposition tendon transfer.

The primary indication for the procedure is congenital absence of the thenar muscles because in addition to restoring opposition, it adds bulk to the thenar eminence, thereby improving the aesthetic appearance of the. The flexor digitorum sublimis tendon to the ring finger has been used to restore thumb opposition using either a tendon loop of the flexor carpi ulnaris as a pulley at the wrist crease or a window.

Tendon transfers for opposition of the thumb were anatomically and biomechanically studied to help determine the optimal criteria for selecting the best motor unit for a transfer.

A large number of tendon transfers have been described that restore opposition to the thumb and provide thumb and finger flexion. To provide optimal results following tendon transfers, one needs to follow the principles of tendon transfer: normal tissue equilibrium, movable joints, and a scar-free bed.

The most prominent tendons in the hands join muscles extending from the arms to the fingers and thumb, or pollux. According to the American Academy of Orthopaedic Surgeons (AAOS), when tendons in the hand are accidentally cut or tear, it may make bending or straightening the fingers challenging, and surgery is usually required this outpatient surgery is performed, recovery involves.

Bone and Joint Surg. 29, –. Tendon repair is done to bring back normal movement to a joint. Tendon injury may occur anywhere in the body where there are tendons. The joints that are most commonly affected by tendon injuries.The EIP tendon is then re-directed and sewn into the thumb bone or thumb tendon (EPL).

After this type of surgery, a splint or cast is used for one month, after which supervised therapy may be started to re-learn how to use the transferred tendon to extend the thumb.Thumb opposition and grasp are separate stages. Opposition does not require a strong muscle/tendon transfer.

Any tendon capable of moving a passively mobile thumb has sufficient force to be an effective opposition tendon transfer. Only when the force of grasp is impaired is a strong tendon transfer required.
