高齢者に認めたFreiberg病に対して骨軟骨移植術を施行した1例

Treatment of Freiberg Infraction in an Elderly Woman by Osteochondral Autotransplantation

　Freiberg病は10歳代の女性認めることが多い第2中足骨頭の無腐性骨壊死であるが，われわれは77歳の高齢女性に発症した比較的稀な1例を経験した．初診時のX線像では異常所見を認めず，MRIがその診断に有用であった．また圧潰した骨頭に骨軟骨移植術を用いて治療し，短期ではあるが経過は良好である．

　Freiberg infraction is aseptic necrosis of the head of the second metatarsal bone and is most common in teenage women. We report a rare case in a 77-year old woman. It was difficult to make the diagnosis, because there were no abnormal radiographic findings on her first visit. Magnetic resonance imaging was very useful in ultimately making the diagnosis. Osteochondral plugging of the head of the bone was performed and good results had been obtained 8 months after surgery.
