観血的治療により完治したモルトン氏病の２例

Abstract

Morton's metatarsalgia presents characteristic pain in the forefoot where the common plantar nerve forms tumorous lesion under the deep transverse matatarsal ligament. In this paper we reported two cases of Morton's metatarsalgia treated with surgical management.In case 1 operated specimen formed asymmetrical spindle-like lesion of the nerve between the third and the fourth metatarsus, and in case 2 the nerve didn't form tumorous lesion but was partly changed in color. The asymmetrical lesion in case 1 is an interesting view etiologically.Histologically, in addition to the characteristics of Morton's metatarsalgia both cases showed bleeding spots in the nerve. We consider this bleeding to be the evidence of minor trauma or direct stimulus from the deep transverse metatarsal ligament.In case that conservative therapy is ineffective, operation should be scheduled. Resection of the nerve by dorsal skin incision meets with good results.
