Tetrahand surgery focuses on restoring hand and arm function for people living with spinal cord injury and other neurological conditions. The goal is to improve independence in everyday activities, such as holding a cup, using a phone,
or feeding oneself

The two main techniques used are nerve transfer  and tendon transfer surgery:

Involves taking a healthy nerve that controls a working muscle (a donor nerve), cutting it, and reattaching it to the nerve of a paralyzed muscle (a recipient nerve). This allows the paralyzed muscle to be “re-animated” and regain function.

Repositions tendons from stronger muscles to replace the function of weaker or paralyzed muscles, improving grip, reach, and limb positioning.

In some cases, these procedures are combined with tendon lengthening, intramuscular Botulinum toxin, splinting, and strengthening therapy to maximize outcomes.

While our primary focus is on spinal cord injury, Tetrahand surgery has also helped people living with stroke, acquired brain injury, cerebral palsy, multiple sclerosis, and peripheral nerve injury.

At its core, Tetrahand is about restoring movement, independence, and quality of life—giving patients back the ability to do the things that matter most.
