How To Regenerate Nerve Damage – When a peripheral nerve is injured or damaged, it has a natural ability to regenerate and regenerate. But, according to Amy Moore, MD, professor and chair of the Department of Plastic and Reconstructive Surgery at The Ohio State University College of , the recovery time is slow: the nerves grow in the A millimeter a day, an inch a month and a foot and a half years.
For Dr. Moore, one of the few peripheral nerve surgeons in the world, is a race against time.
How To Regenerate Nerve Damage
“Muscle cells die and cannot be regenerated after 18 months to two years after injury,” said Dr. Moore. “We need rehabilitation and additional therapies, like ES, to improve regeneration and function.”

The science of delivering electrical stimulation (ES) into the body has been around since the 1980s, when medical pioneers used it in animal models and later in humans. ES was found to help the nerves to repair better and better at the neuronal level. The problem is, the device requires a series of wires, which are spread from the wound and attached to the paralyzed device. Eventually, it proved too late and useless.
“Checkpoint Surgical has already created an FDA-approved surgical device used today to scan nerves,” said Dr. Moore. “It makes sense to work with them to test its effectiveness in our research that focuses on nerve regeneration.”
Three clinical studies have confirmed that the form of ES and this mechanism improves nerve regeneration after injury.
Through these special studies, the safety of the machine has been confirmed and they have also been able to identify the best answer, which is 10 minutes. Pilot data from our clinical trials showed no adverse outcomes or side effects.

“We made a device that can be attached to a nerve and give 10 minutes of ES,” said Dr. Moore. “We don’t have to extend the length of surgery or waste time in the OR.”
A review of ES research, “The Effect of Electrical Stimulation on Nerve Regeneration Following Peripheral Nerve Damage,” was recently published in the journal Biomolecules. The Ohio State authors also contributed a sample of the ES that was used as an illustration for this publication.
This work is supported by a large grant from the US Department of Defense, which includes Walter Reed National Military Medical Center, Northwestern University, Washington University in St. Louis and the Medical College of Wisconsin. It integrates research being done at Ohio State’s Military Program.
“Military combat and wounded soldiers have a high rate of nerve injury and we need a way to help improve outcomes,” said Dr. Moore. “This is a way we are giving back to this community.” One of the biggest problems we see after surgery is nerve scarring (1). The most common symptoms of nerve damage after surgery are usually numbness, tingling, burning, muscle weakness or atrophy. Most of the time the symptoms are temporary, for example, many patients have neurological problems after surgery that only last a few weeks to months (2, 3). If they last longer than a few months, then put in permanent nerve damage and need to be treated.
Increasing Energy Supply In Injured Spinal Cord Nerves May Help Promote Axon Regrowth
Think of a nerve as a garden hose. If you limit one area, less water will come out. This is what happens when a nerve is pinched after surgery. The scar that surrounds the nerve reduces the transport of dangerous chemicals that the nerve needs to stay healthy.
A nerve can also be damaged by killing some or all of its fibers. The diagram below shows that the nervous system is made up of bundles of neurons (nerve cells) called fascicles. Parts of these fascicles make up the spinal cord (4). In addition, the nerve is surrounded by a fatty tissue (myelin) that acts as an insulator covering a wire. When this nerve becomes damaged it can also cause problems with nerve function.
Something between 0.5% and 2% of patients will have permanent nerve damage after surgery. Temporary nerve injuries are more common, especially in spinal surgery. See below for the neurological effects of some common procedures:
This is an electrical test of nerve function. One subject is very special but has a low sensitivity. This usually only results in more severe nerve damage (7).

This test can determine if multiple nerves are showing inflammation and/or compression. It works as well as neural tube scans and is less invasive (8).
Most of the nerve damage after surgery lasts for a few weeks to a few months. If they last long, then the rate of nerve regeneration is about an inch per month. Therefore, if the nerve can regenerate, a back injury may take years to regenerate the entire nerve from your back to your leg (10). However, often scarring in or around the nerve prevents recurrence (11).
How do you break down the scar tissue around the nerves? Obviously, since the scar was caused by surgery, using surgery to remove it can be problematic. However, there is a new way to help the nerves heal and eliminate the scar called ultrasound-guided nerve hydrodissection with orthobiologics. In this procedure, a nerve is seen on ultrasound. This is used to guide a small needle to inject fluid around the nerve to break up the scar tissue.
In this procedure, which builds on our published work in the treatment of spinal nerves and platelets, we inject the patient with the same growth factors that can help in the recovery of nerves through cytokines such as NGF, PDGF, and IG-1 (17, 18). To see how this works on the median nerve in the carpal tunnel, watch the following video.
Regenerating The Optic Nerve
Tanya had plastic surgery on her gluteal area and ended up with a severe infection that caused scarring to the sciatic nerve. This caused his leg to die. So when I met him he was wearing a special brace to walk and it was very tight and very painful down the leg. He could barely go up or down a flight of stairs. I did the ultrasound-guided nerve hydrodissection with orthobiologics procedure a total of four times during the year. I treated the entire length of the nerve, starting at the bottom using fluoroscopy guidance, then turned to ultrasound guided injections to treat the sciatic nerve down to the tibial and peroneal branches in the leg and the feet Where is he today? He no longer wears the bandage, has regained sensation, and is in less pain. He does 30-inch box jumps at CrossFit and plans to compete in a bodybuilding competition!
Ivy had a bad IV stick in her arm where they injured the cutaneous branch of the ulnar nerve. Sadly, she developed chronic pain syndrome (CRPS) type 2 and the pain was so severe that she couldn’t touch a hand for days. This is why it is so difficult to work with children as a nurse practitioner, because they often hold that sick hand.
I did the ultrasound-guided nerve hydrodissection with orthobiologics procedure a total of four times over about a year, injecting around all the nerves in the hand, the ulnar nerve in the wrist and elbow, and the nerves in the neck . The strength of his grip went from insignificant to normal. Now he has little pain for several days and can see the children without any problem. This is especially surprising because there are very few treatments for patients when severe CRPS occurs.
The result? Nerve damage after surgery that does not go away after several months can be devastating. However, new non-surgical nerve repair techniques may help.
