Abstract
We reviewed eight patients who sustained superficial peroneal nerve neuralgia after an inversion ankle sprain. Surgical exploration found anatomic abnormalities that tethered the nerve from movement during plantarflexion and inversion of the ankle. Most patients' pain improved dramatically after release and anterior transposition of the nerve. Seven joints also underwent arthroscopy, which showed intra-articular disease that was consistent with the original trauma. Five patients had reflex sympathetic dystrophy, three of which resolved after nerve release. Nerve conduction studies were not helpful. Careful physical examination and local nerve blocks were most important in making the diagnosis and prescribing treatment. All conservative measures should be exhausted before surgery is considered.
