Over time, these feelings subside and the area should begin to feel more normal. Unfortunately, nerves never recover completely after they have been cut. I use a microscope or magnifying glasses loupes to repair your cut nerve with sutures finer than a human hair.
This type of nerve repair surgery has the best recovery rates. Whether or not I can perform direct nerve repair on your injured limb depends on the injury your nerve has suffered. Sometimes I cannot directly repair your nerve ends, for example, if there is a piece of nerve missing or a delay in repair.
With nerve grafting, I take a length of nerve from somewhere else in your body and place it as a graft. I perform this repair using a microscope, too. You will have a scar from the surgery and often a numb patch in the area I took the nerve graft from. Possible donor nerves include sensory nerves of skin of the forearm and leg. Having a numb patch on the side of your arm or foot is usually less bother than having a numb area on your hand.
As with all procedures I perform, we will have an in-depth consultation about all aspects of the surgery and recovery, including possible donor nerves, risks etc. The nerve may have been repaired, and some recovery of function may have occurred, however scar tissue around the nerve causes tethering and discomfort when you move your hand.
The scar tissue can also limit nerve cell regeneration. I can surgically release the scar tissue from around the nerve. Your nerve may fail to recover due to a neuroma link to the top of the page , or there is a persistent gap in the nerve. During the procedure, I cut back your nerve ends until I can see healthy ends, and I place a piece of nerve graft to facilitate normal re-growth of your nerve.
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. For instance, you may need to stop taking certain medications for a few days or avoid using lotions the day of the test. If possible, take along a family member or friend.
Sometimes it can be difficult to absorb all the information you're given during an appointment. Someone who accompanies you may remember something that you forgot or missed.
