Successful delayed reconstruction of common peroneal neuroma-in-continuity using sural nerve graft

Injuries of the common peroneal nerve (CPN) are frequent and associated with poor motor outcomes. So far, the opinion is held, that nerve reconstruction is reasonable and indicated up to 6 months after injury. We describe successful sural nerve interposition grafting in a patient with neuroma-in-continuity formation of the CPN, presenting with foot drop, 13 months after injury. Due to this positive result, we think nerve grafting in neuroma-in-continuity lesions of the CPN should be contemplated in patients with foot drop even more than one year after injury.
