OVERVIEW

A tendon transfer is a surgical procedure designed to address the functional deficits resulting from chronic nerve injuries. When nerves are damaged or severed, the signals between the brain and muscles are disrupted, leading to muscle weakness, loss of sensation, and impaired motor function. A tendon transfer involves relocating a healthy tendon to replace the function of a damaged or paralysed tendon, restoring movement and function to the affected area.

Types of tendon transfer for chronic nerve injury

Chronic nerve injuries can result from various causes, leading to a range of conditions that affect the peripheral nervous system. The types of chronic nerve injuries are often classified based on the nature of the injury and the specific nerves involved. Here are some common types:

1. Brachial Plexus Injury: The brachial plexus is a delicate network of nerves that controls movement and sensation in the shoulder, arm, and hand. Injuries to the brachial plexus can occur during childbirth, trauma, or accidents, leading to weakness or paralysis in the affected arm.
2. Ulnar Nerve Injury: The ulnar nerve runs from the neck down the arm and into the hand. Injuries to the ulnar nerve can result in symptoms such as tingling in the ring and little fingers, weakness in the hand, and difficulty with fine motor skills.
3. Radial Nerve Injury: The radial nerve controls the muscles in the forearm and hand. Injuries to the radial nerve can occur due to trauma or compression, leading to symptoms such as wrist drop, weakness, and numbness.

Tendon transfer indications:

A tendon transfer is often recommended when traditional treatments, such as physical therapy and medications, prove insufficient in restoring normal function following a chronic nerve injury. Common causes include:

1. Trauma: Accidents or injuries resulting in nerve damage, such as fractures or dislocations.
2. Compression injuries: Prolonged compression or pressure on nerves, leading to chronic damage.
