習慣性肩関節脱臼に対するＯｕｄａｒｄ‐神中変法

Abstract

Many procedures have been devised for recurrent anterior dislocation of the shoulder. In our hospitals, the Oudard-Jinnaka has been the most frequently performed operation since 1937. The present report is that of our experience with the procedure. From 1953 to 1985, we did a total of thirty-eight Oudard-Jinnaka procedures for the anterior instability excluding the multidirectional instability and the recurrent anterior subluxation. A follow-up was undertaken of thirty patients. The age of the patients ranged from sixteen to thirty-eight years and averaged twenty-three years at the time of the operation. Twenty-three procedures were done in male patients and 7, in female. They were followed for one to thirty-two years. The average follow-up was eleven years. Five of the thirty patients redislocated their shoulders from four months to nineteen years after operation.They had no recurrences during the ensuing years. Redislocation occurred in one of twenty-three patients in whom the bone graft was longer than 3cm as indicated in the manual. In shoulders in which the bone graft was shorter than 2.5cm, the incidence of redislocation was significantly increased.
