Neurologic deficit has been implicated as a possible etiology for clubfoot and a cause for recurrent deformity in patients who have undergone clubfoot surgery. In the study reported here, we wanted to determine if clubfoot patients with peroneal weakness had any neurologic deficits on electromyography nerve conduction velocity (EMG-NCV) studies before surgery and if there was any association between neurologic deficit and clubfoot recurrence. We reviewed the EMG-NCV studies of 36 patients involving 57 cases of idiopathic clubfoot and recurrence of the deformity or muscle weakness. In the clubfoot patients with weak peroneal muscle and no prior surgical history, 45% of the studies were interpreted as normal, 20% as neuropathic, 15% as mixed myopathic and neuropathic, 10% as radicular, and 10% as myopathic. In the clubfoot patients with recurrence after clubfoot repair surgeries, 57% had abnormal EMG-NCV studies. Specifically, peroneal mononeuropathy was the most common disorder (41% of clubfoot patients treated surgically). Awareness of a significant incidence of neurologic deficit may help in preoperative planning by indicating that ultimately a tendon transfer may be necessary to obtain a plantigrade foot.
