Aseptic necrosis of the sesamoids of the first metatarsal bone is rarely reported in the past. Recently, a patient with such lesion was admitted in our hospital; A Case: A woman aged 21, without any overt trauma, found sore at the left great toe region while walking.
Clinical examinations revealed slight tenderness on lateral aspect of the distal end of the left first metatarsal bone and pain on dorsiflexion of the great toe. Urine and blood examinations showed normal data. On X-ray examination the lateral sesamoid of the first metatarsal bone was separated by antero-posterior and lateral views and stippled radioopacity by the axial view.
She was diagnosed as aseptic necrosis of the sesamoid of the left first metatarsal bone. After sesamoidectomy the pain disappeared.
