Entrapment of the superficial peroneal nerve. Diagnosis and results of decompression.J Bone Joint Surg Br. 1989 Jan; 71(1):131-5.JB
Entrapment of the superficial peroneal nerve was treated in 24 legs of 21 patients by fasciotomy and neurolysis; 19 of the patients were reviewed after a mean period of 37 months. Nine were satisfied with the result, another six were improved but not satisfied because of residual limitation of athletic activity, three were unchanged and one was worse. Conduction velocity in the superficial peroneal nerve had increased after operation, but the change was not significant. In five patients the nerve had an anomalous course and in 11 there were fascial defects over the lateral compartment. Chronic lateral compartment syndrome is an unusual cause of nerve entrapment. Operative decompression produces cure or improvement in three-quarters of the cases, but is less effective in athletes.
