A peroneal nerve palsy is one of the most common peripheral nerve injuries. A retrospective analysis of 275 peroneal nerve palsies was carried out from 11 years experience (since 1972 to 1982) in the Department of Rehabilitation Medicine, Yonsei University College of Medicine.

The third decade was involved most frequently and the females were more prevalant than the males with the ratio of 3.3:1. The most frequent site of the lesions was the common peroneal nerve(51.8%). For the cause of lesions, the fracture was most common(32.2%). A complete and an incomplete lesions were 47.9% and 52.1% of all cases respectively.
