nerve damage after surgery

Can nerve damage after surgery be treated? Does this require more surgery or can it be treated without surgery? Let’s dig in.

What Happens When Your Nerves are Damaged?

nerve anataomyOne of the biggest issues we see after surgery is scarring around nerves (5). Think of a nerve as a garden hose. If you constrict one area, less water comes out the end. This is what happens when scar tissue forms around a nerve after surgery. The scar tissue constricts the nerve which reduces the transport of critical chemicals that the nerve needs to stay healthy.

A nerve can also be damaged by killing some or all of its fibers. The image to the left shows that a nerve is made up of many neurons (nerve cells) that are bundled into fascicles and then bundles of these make up the bigger nerve (6). In addition, the nerve is surrounded by a fatty sheath that acts like an insulator covering a wire (myelin) and when this gets damaged there can also be a problem with nerve function.

In summary, nerve damage is broken into neurapraxia (damage to the covering of the wire or myelin sheath), axontomeis (damage to the wire itself or the neurons), and neurontomesis (the nerve is torn or cut in half).

How Common is Nerve Damage After Surgery?

Somewhere between 1 in 200 to 1 in 50 patients will have permanent nerve damage after surgery. Temporary nerve injury is much more common, especially in spine surgeries. See below for the nerve-related side effects of several common procedures:

  • Hip replacement-0.2-0.6% (1)
  • Low back surgery-fusion (transient nerve injury lasting less than 3 months)-50-62% (2,3)
  • Shoulder replacement surgery-21% temporary nerve damage, 2% had permanent nerve damage (4)

What does Nerve Damage after Surgery Feel like? What are the Signs of Nerve Damage?

The biggest symptoms of nerve damage after surgery are usually numbness, tingling, burning, or muscle weakness or atrophy. Many times nerve issues after surgery are temporary, for example, many patients have nerve problems after surgery that only last for a few weeks to months (2,3). If they last longer than a few months, then they’re placed into the permanent nerve damage category and will likely need to be treated.

What Test Shows Nerve Damage?

There are a couple of tests to consider if you or your doctor suspect nerve damage after surgery:

  • EMG/Nerve Conduction Study-This is an electrical test of the nerve’s function. One issue is that it is highly specific, but has low sensitivity. Meaning that it will usually only pick up nerve damage that is more severe (7).
  • Ultrasound imaging of the nerve-This test can determine if the nerve size shows swelling and/or constriction. It works about as well as a nerve conduction study and is less invasive (8).
  • MR Neurography-This is a very specialized MRI scan that’s tuned to show the nerves (9).

How Long does it Take for Nerves to Repair after Surgery?

As above, most episodes of nerve damage after surgery last for a few weeks to a few months. If they last longer, then the rate of nerve regrowth is about an inch a month or faster. Hence, if the nerve is able to regrow, a nerve injury in the back could take years to regenerate the entire nerve from your back to your foot (10). However, many times scarring in or around the nerve prevents regrowth (11).

What Helps with Nerve Pain after Surgery?

Physical therapy may help. Medications that are commonly used to treat the nerve damage after surgery include:

  • Neurontin (Gabapentin) (12)
  • Lyrica (Pregabalin) (13)
  • Elavil (Amitriptyline) (14)
  • Topomax (Topiramate) (15)
  • Ultram (Tramadol) (15)

Ultrasound-Guided Nerve Hydrodissection with Orthobiologics

How can you break up scar tissue around nerves? Obviously, since the scar tissue was caused by surgery, using surgery to get rid of it can be a problem. However, there’s a new way to help nerves heal and get rid of the scar tissue which is called Ultrasound-Guided Nerve Hydrodissection with Orthobiologics. In this procedure, a nerve is visualized with ultrasound which is used to guide a small needle to inject fluid around the nerve to break up the scar tissue. In this procedure, which builds off our published work on treating spinal nerves with platelets, we inject the patient’s own platelet-derived growth factors that can assist nerve repair through cytokines like NGF, PDGF, and IG-1 (17,18). To see how this works on the median nerve in the carpal tunnel, see my video below:

Does this work? I cover two cases below.

Tanya’s Story

Tanya had a plastic surgery procedure on her gluteal area and ended up with a severe infection which caused scarring around the sciatic nerve. This basically gave her a dead leg, so when I met her she was wearing a special brace to walk, had significant numbness, and severe pain down the leg. She could barely go up or down stairs. I performed the Ultrasound-Guided Nerve Hydrodissection with Orthobiologics procedure a total of 4 times over about a year. I treated the entire length of the nerve, starting in the low back using fluoroscopy guidance and then using ultrasound-guided injections to treat the sciatic nerve down to the tibial and peroneal branches in the leg and foot. Where is she today? She no longer wears the brace, has gotten sensation back, and has limited pain. She does 30-inch box jumps in cross fit and is planning on competing in a bodybuilding competition!

Ivy’s Story

Ivy had a bad IV stick in her hand during which they injured the cutaneous branch of the ulnar nerve. Regrettably, she developed Complex Regional Pain Syndrome (CRPS) type 2 with pain so severe she couldn’t have anyone touch the hand most days. This made it very difficult to work with kids as a nurse practitioner, as they often grabbed that hypersensitive hand. I performed the Ultrasound-Guided Nerve Hydrodissection with Orthobiologics procedure a total of four times over about a year, injecting around the nerves in the hand, the ulnar nerve at the wrist and elbow, and the nerves in the neck. Her grip strength went from pitiful to normal. Today she has very little pain most days and can see kids without a problem. This is especially remarkable, as there are few treatment options for patients once severe CRPS sets in.

The upshot? Nerve damage after surgery that doesn’t go away after a few months can be devastating. However, newer non-surgical nerve repair techniques may be able to help.

  1. Robin Baumgartner

    Hi Dr. Centenno, I was wondering if this procedure would work with someone who has nerve damage due to guillain barre syndrome.

    1. Chris Centeno, MD Post author

      Possible, but we have not treated many of these patients, mostly post-surgical nerve injury or compression syndromes.

  2. Edward D Hochard

    I still have numbness in the front of my knee after total knee replacement and its hard to kneel on the knee. Any thoughts?

    1. Regenexx Team

      Hi Edward,
      This is, unfortunately, not unusual as nerve damage is one of the many risks of joint replacement.

Spine

Many spine injuries and degenerative conditions are good candidates for regenerative treatments and there are a number of studies showing promising results in treating a wide range of spine problems. Spine surgery should be a last resort for anyone, due to the cascade of negative effects it can have on the areas surrounding the surgery. And epidural steroid injections are problematic due to their long-term negative impact on bone density.

Knees

Knees are the target of many common sports injuries. Sadly, they are also the target of a number of surgeries that research has frequently shown to be ineffective or minimally effective. Knee arthritis can also be a common cause for aging athletes to abandon the sports and activities they love. Regenerative procedures can be used to treat a wide range of knee injuries and conditions. They can even be used to reduce pain and delay knee replacement for more severe arthritis.

Hip injuries and degenerative conditions become more common with age. Do to the nature of the joint, it’s not quite as easy to injure as a knee, but it can take a beating and pain often develops over time. Whether a hip condition is acute or degenerative, regenerative procedures can help reduce pain and may help heal injured tissue, without the complications of invasive surgical hip procedures.
