Traditionally, doctors have relied on two techniques to treat jagged nerve injuries that cause gaps in nerves. One technique is called a “nerve autograft” which takes nerve tissue from one part of the patient’s body and uses it to repair the injured nerve. However, because the nerve used to repair the injured nerve is harvested from another part of the patient’s body, the harvest site experiences a “nerve deficit.” The other approach is to use a “nerve conduit,” a synthetic tube that fills the gap in the nerve. A nerve conduit may cause problems for the patient because implants can be rejected by the patent’s body or become infected.
However, a recent study conducted by Dr. Brian Ringer suggests that a new treatment known as a “nerve allograph” can repair the gap in a severed nerve without the side effects of the two traditional methods of treatment. An allograft uses an actual human nerve, taken from a cadaver, to repair the patient’s nerve injury. The study found less foreign body reactions and infections when compared to nerve conduit operations, and the technique does not leave the patient with a nerve deficit somewhere else in the body.
