Foot reanimation via nerve transfer to the peroneal nerve using the nerve branch to the lateral gastrocnemius: Case report

Injury to the peroneal nerve can be devastating to a patient's daily function. By paralyzing the ankle dorsiflexors, peroneal neuropathy results in foot drop. Gait difficulties and other functional limitations impede these patients on a daily basis. Knee and ankle injuries, lacerations, and compression are only a few of many etiologies which make peroneal nerve palsy the most common neuropathy of the lower limb. We present a case of peroneal nerve palsy secondary to an ACL and lateral collateral ligament tears. This 18 year old male underwent foot reanimation via nerve transfer to the peroneal nerve using the branch from the lateral gastrocenus to tibalias anterior muscle branch. The patient was followed and assessed for function during the subsequent two years. This case reports provides a synopsis of this patient's surgical treatment, as well as a glance into the literature surrounding peroneal nerve transfer.
