Bankart-Bristow 変法の術後合併症について

抄録

The aim of this study was to clarify the complications of Bankart and modified Bristow procedure using a cannulated cancellous screw for recurrent anterior dislocation of the shoulder.25 shoulders who had received a Bankart and modified Bristow procedure and were able to be observed for more than a year postoperatively were investigated. We used a few suture anchors for Bankart repair, and a cannulated cancellous screw with a washer to fix the coracoid tip to the glenoid neck. There were 19 men and 6 women, whose average age at surgery was 29.1 years old(16-60 years old). We evaluated the complications about non-union of the coracoid tip, breakage of the screw, loosening of the screw and the loss of external rotation more than 20 degrees postoperatively. There were no re-dislocations or subluxations postoperatively. The complications were non-union in 4 cases, breakage of the screw in 1 case, loosening of the screw in 4 cases, and the loss of external rotation in 3 cases. Some cases overlapped. Using a cannulated cancellous screw to fix the coracoid's tip to the glenoid neck is uncertain. It is desirable that a national research about the complications of Bankart and modified Bristow procedure be performed.
