Answer

Common peroneal nerve decompression is a useful procedure to improve sensation and strength as well as to decrease pain. [5]

A retrospective study evaluated electrodiagnostic prognostic factors after peroneal nerve injury in 39 subjects. Outcome was associated with compound muscle action potential responses from extensor digitorum brevis and tibialis anterior: 81% of subjects with any tibialis anterior response and 94% with any extensor digitorum brevis response had a good outcome (at least 4 of 5 ankle dorsiflexion strength) compared with those with absent responses (46% and 52%, respectively). In addition, all patients with nontraumatic compression had a good outcome. [6]
