Endoscopic Decompression of the First Branch of the Lateral Plantar Nerve and Release of the Plantar Aponeurosis for Chronic Heel Pain.

Entrapment of the first branch of the lateral plantar nerve is a commonly missed cause of recalcitrant plantar heel pain. The diagnosis is made on a clinical ground with maximal tenderness at the site of nerve entrapment. Treatment of the nerve entrapment is similar to that for plantar fasciitis, with rest, activity modification, nonsteroidal anti-inflammatory drugs, stretching exercise, and local steroid injection. Surgical release of the deep abductor hallucis fascia is indicated when conservative treatment failed. Endoscopic release of the nerve through the dorsal and plantar portals, as well as endoscopic plantar aponeurosis release, is a feasible approach.
