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:

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.

Wrist Tenodesis

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

-'''Tenodesis grasp''' is a functional grasp pattern that is often used by individuals with [[spinal cord injury]] at the C6 or C7 level. This grasp pattern is achieved through the use of wrist extension to create finger flexion and wrist flexion to create finger extension.

-== Mechanism ==
+==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]].
-The tenodesis grasp works on the principle of [[tenodesis]] action. When the wrist is extended, the fingers and thumb flex (close) due to the increased tension on the finger flexor tendons. Conversely, when the wrist is flexed, the fingers and thumb extend (open) due to the decreased tension on the finger flexor tendons. This action allows individuals with certain types of spinal cord injuries to grasp and release objects.
+==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:
-== Use in Rehabilitation ==
+* [[Rotator cuff]] tears
+* [[Biceps tendon]] injuries
+* [[Achilles tendon]] ruptures
+* [[Wrist drop]]
-In [[rehabilitation]], the tenodesis grasp is often used to improve functional independence in individuals with spinal cord injuries. Occupational therapists may train patients to use this grasp pattern to perform activities of daily living, such as eating, dressing, and writing.
+==Procedure==
+The tenodesis procedure involves the surgical attachment of a tendon to a bone. This can be achieved through various techniques, including:
-== Limitations ==
+* '''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.
-While the tenodesis grasp can improve functional independence, it has some limitations. The strength of the grasp is limited by the strength of the wrist extensors. Additionally, the grasp is less precise than a normal hand grasp and may not be suitable for all tasks.
