Morton's metatarsalgia. Clinical, electrophysiological and histological observations.
In an attempt to improve the accuracy of diagnosis, 16 patients suffering from Morton's metatarsalgia were investigated clinically and electrophysiologically. The histological findings were related to these observations. The precise aetiology of Morton's metatarsalgia remains obscure, but the findings are compatible with an entrapment syndrome. Nerve conduction studies have a place in the investigation of patients with atypical presentation of pain in the foot. Further refinement of the electrophysiological technique should be possible.
