Abstract

Intermetatarsal coalition (IC) is very rare; although few cases have been reported in foreign orthopedic journals, these have not originated in our country. We report the case of a 20-year-old man who complained of pain in the left forefoot only during long distance running (3 km). On examination, his foot shape, skin appearance, and gait were normal, with no plantar keratosis; however, the radiograph revealed coalition between the fourth and fifth metatarsals. Surgical excision was performed. In the histopathologic study, fibrous coalition was confirmed. This paper reports an uncommon case involving surgical excision of IC in the military service, involving active sport activity.
