Answer

Nerve graft complications include neuroma formation or fibrotic ingrowth along the graft, preventing proximal axon sprouting and causing failure of graft. This complication may be found in patients who received radiotherapy postoperatively or in patients in which a long and nonvascular graft was used. Another complication is morbidity of the donor site that is associated with harvesting the autologous nerve graft.
