The potential donor nerves for auto-grafting is
limited to cutaneous nerves of the extremities, most commonly
-
Superficial radial nerve
-
Medial cutaneous nerves of the arm and forearm,
-
Posterior and lateral cutaneous nerves of the
thigh
-
Sural nerve
-
Lateral cutaneous nerve of the forearm
-
Superficial peroneal nerve
Other sources of nerve graft that have been
reported include the intercostal nerves and the segmental motor nerves of the rectus
muscle. These are small nerves that are difficult to dissect and only used
in unusual circumstances. Recently, nerve allografting
requiring systemic immunosuppresion has been performed. This area is
controversial since immunosupression medications can increase the risk of infection
and can also lead potentially to a risk of kidney failure and cancer.
