腓骨筋腱脱臼に対する上腓骨筋支帯の解剖学的修復術

Anatomical Repair of Superior Peroneal Retinaculum for Acute and Chronic Dislocation of Peroneal Tendons

　腓骨筋腱脱臼に対する上腓骨筋支帯修復術の術後成績を検討した．対象は腓骨筋腱脱臼に対して手術を行った14例14足（男性11足，女性3足，平均31歳）とした．経過観察期間は平均1年11カ月であった．手術所見より損傷形態を3型に分類し，解剖学的な上腓骨筋支帯修復術を行った．最終調査時，JOAスコア，AOFASスケールはいずれも平均99点であった．12例は疼痛が消失したが，スポーツ後の軽度の疼痛を2例に認めた．可動域制限や再脱臼は認めなかった．われわれの術式は新鮮および陳旧性の腓骨筋腱脱臼に有用であった．

　We reviewed the results of surgical treatment in 14 patients (14 feet；mean age of patients, 31 years) with acute or chronic dislocation of the peroneal tendons. The average follow-up was 23 months. The injury of the superior peroneal retinaculum was classified into three types according to operative findings. All patients were treated with anatomical repair of the superior peroneal retinaculum. At the final follow-up, the mean scores on the AOFAS scale and JOA score were 99 points and 99 points, respectively. Twelve feet had free from ankle pain. The remaining two feet had mild ankle pain during sports activities. There were no cases, which had postoperative limitation of the ankle motion or the recurrence of peroneal tendon dislocation. Our surgical procedure was effective method for acute and chronic peroneal tendon dislocation.
