There are some diseases which the main symptom is pain under the first metatarsal head. We have studied on roentgenograms of the first metatarsal sesamoid of 27 patients whose main symptom is pain under the head of the first metatarsal, betweeen 1966 and 1973.
In these patients studied here, there found partition of the sesamoid in 16 patients and mottling of the sesamoid in 2 patients.
A 16-year-old boy complained of pain under the left first metatarsal head. The axial view of the first metatarsal sesamoid showed “mottling” and this boy was made a diagnosis of “aseptic necrosis of the lateral sesamoid of the first metatarsal”. Conservative treatment for two months was unsuccessful and excision of the involved sesamoid was performed with excellent result. The postoperative diagnosis was “aseptic necrosis of the lateral sesamoid of the first metatarsal.”
