Care at Mayo Clinic Our caring team of Mayo Clinic experts can help you with your peripheral nerve injuries-related health concerns Start Here. Peripheral nerve graft Open pop-up dialog box Close. Peripheral nerve graft To repair a damaged nerve, your surgeon removes a small part of the sural nerve in your leg and implants this nerve at the site of the repair.
Nerve transfer Open pop-up dialog box Close. Nerve transfer Your surgeon can bypass a damaged section of nerve by reconnecting a healthy nerve to restore function. Request an Appointment at Mayo Clinic.

Azar FM, et al. Peripheral nerve injuries. In: Campbell's Operative Orthopaedics. There are over different types of nerve damage. These numbers increase as we enter middle age and beyond. Here are some of the possible causes of nerve damage:. Call Today. View More. Nerves are composed of many fibers, called axons. Axons are separated into bundles within the nerve. A ring of tissue provides a kind of insulation and protection around the nerve.
While spinal cord nerves cannot heal themselves, peripheral nerves have the ability to regenerate. If both the nerve and the outer insulation are cut, the nerve will need to be fixed to regain function.
Otherwise, it will for a painful nerve scar, called a neuroma. Sometimes fibers inside the nerve break, but the outer insulation remains intact and healthy. These nerves can heal. The end furthest from the brain will die, but the end closer to the brain will not.
New nerve fibers may then grow to replace those that die. When a nerve is cut, surgery is required to fix it and allow it to regenerate.
This involves sewing the insulation back together at the cut. The goal in fixing a nerve is to save the insulating cover so that new nerve fibers can grow and the nerve can regain function. If there is a gap where the nerve was severed, it may be necessary to place a nerve graft to fill the gap.
This graft needs to come from a donor part of the body, and that area may then have some permanent loss of feeling. Once the insulating cover is repaired, the nerve generally begins to heal three or four weeks later.
Nerves grow about one inch per month, so it can take some time for feeling to return. A sign that the nerve is regenerating after an injury to the wrist, for instance, would be a feeling of pins and needles in the fingertips.
Seruya and the staff provided exceptional care to my son. All were very professional and friendly. I was very impressed with Dr. Seruya went out of his way to help! The function sensation and power of your nerve is initially worse and then should gradually improve — it will be like beginning recovery all over again.
The pain and discomfort you feel at the site of injury improves as recovery progresses. Sometimes a nerve is persistently tender. This is usually due to a neuroma. Wrapping a vein, fat or another substance around your nerve provides padding around the nerve and will make the area less sensitive.
After a nerve is injured, sometimes painful neuromas develop in smaller nerves of your hand. They are usually in locations that are not suitable for nerve repair such as amputated fingers.
I can cut away the neuroma and bury the nerve end deep in a muscle or bone. This prevents the nerve end from being knocked and should reduce the electric shock like pain. The area that the nerve supplied will be completely numb, and this is permanent.
You will be given antibiotics at the beginning of your procedure and occasionally after your operation. Antibiotic use is carefully monitored to reduce antibiotic resistance.
The signs of infection to look out for include increasing redness, swelling, pain and purulent discharge. Most wound infections will respond quickly to antibiotics.
Very occasionally further surgery may be required to clean out a deeper infection. Infection can lead to delayed recovery and increased stiffness. I may ask you see an expert hand therapist to provide you with a splint and complete a personalised regime of exercises to reduce stiffness. Please read more about the hand therapists that I work with. Some people have hands that are very sensitive to surgery or trauma and become very painful, stiff and swollen following surgery. This is treated with special kinds of pain relief and physiotherapy.
