[Peroneal nerve palsy due to rare reasons: a report of three cases]

Peroneal nerve entrapment was diagnosed in three patients (2 males, 1 female) by clinical and electrophysiological studies. Of these, one patient had postural bilateral involvement due to prolonged squatting, while two patients had mechanically-induced entrapment. Initially, all the patients were treated conservatively with a drop-foot splint and vitamin B. One patient responded to treatment; in one patient with bilateral involvement, right-sided peroneal nerve palsy improved. Upon detection of no clinical and electrophysiological improvement after three months of conservative treatment, surgical decompression was performed in two patients, which resulted in a successful outcome in the patient with bilateral palsy. Incomplete recovery was obtained in the other patient with diabetic polyneuropathy.
