Right Common Peroneal Neuropathy after Vaginal Delivery

Postpartum common peroneal neuropathy is rare. Causes of peroneal neuropathy include prolonged external knee compression like lithotomy position or knee hyperflexion and epidural analgesia. We report a case of right common peroneal neuropathy after vaginal delivery. A 20yearold nulliparous woman complained of weakness and abnormal sensation of right foot after vaginal delivery. Lumbar magnetic resonance imaging results are normal, but needle electromyography reveals abnormal spontaneous activities in right tibialis anterior and right extensor hallucis longus. These findings are suggestive of right common peroneal neuropathy with mild axonotmesis. The patient had fully recovered at 6 weeks after the delivery with conservative management include stretching and range of motion exercise. Peroneal neuropathy is rare, but understanding of the risk factor and preventive measure for peroneal neuropathy is important for delivery team.
