Peroneal paralysis due to exostosis of the fibula. Report of 2 cases.

Exostoses in certain situations such as the armpit or the popliteal region, can cause vascular or neurological compression syndromes. Exostoses of the neck of the fibula can in this way produce late paralysis of the peroneal nerve. Two such cases are presented in young patients, in whom the neurological damage was produced by increased growth distally of the neoplasm.
