Tenodesis grasp

A surgical procedure involving the fixation of a tendon to a bone

Overview

Tenodesis is a surgical procedure that involves the fixation of a tendon to a bone. This procedure is often used to restore function or stability to a joint by altering the mechanics of the tendons and muscles involved. Tenodesis can be performed in various parts of the body, including the wrist, shoulder, and ankle.

Indications

Tenodesis is indicated in cases where there is a need to stabilize a joint or restore function due to tendon injury or dysfunction. Common indications include:

• Rotator cuff tears
• Biceps tendon injuries
• Achilles tendon ruptures
• Wrist drop

Procedure

The tenodesis procedure involves the surgical attachment of a tendon to a bone. This can be achieved through various techniques, including:

• Suture anchors: Small anchors are inserted into the bone, and the tendon is sutured to these anchors.
• Bone tunnels: Holes are drilled into the bone, and the tendon is passed through these tunnels and secured.
• Screws: Special screws are used to attach the tendon directly to the bone.

In the wrist, tenodesis is often used to treat conditions such as wrist drop, where the extensor tendons are not functioning properly. The procedure involves attaching the tendons of the wrist extensors to the bones of the wrist to restore extension.

Shoulder Tenodesis

In the shoulder, tenodesis is commonly performed for biceps tendon injuries. The long head of the biceps tendon is detached from its original attachment and reattached to the humerus, relieving pain and restoring function.

Recovery

Recovery from tenodesis surgery varies depending on the location and extent of the procedure. Generally, patients can expect:

• Immobilization of the joint for a period of time to allow healing
• Physical therapy to restore range of motion and strength
• Gradual return to normal activities over several weeks to months

Complications

As with any surgical procedure, tenodesis carries risks of complications, including:

• Infection
• Nerve damage
• Failure of the tendon to heal properly
• Loss of range of motion
