A Review of the Modified Bristow Procedure for Recurrent Anterior Shoulder Dislocation

We reviewed sixteen cases using the modified Bristow procedure for treatment of recurrent anterior shoulder dislocation. Twelve patients were male and four were female. All patients had the procedure performed laterally. Ten shoulders were on the right and eleven shoulders were on the dominant side. The follow-up period ranged from one to 11yaers and one month (mean, 5 years and 5 months).Postoperatively, one patient had subluxation on one occasion but none had redislocation. Evaluation using the shoulder evaluation sheet of the Japan Orthopedic Association resulted in an average point score of 94.4, and 15 patients were subjectively satisfied with this procedure. The mean loss of external rotation was 12.2 degrees with the arm at the side and 7.5 degrees with the arm at 90 degrees of abduction.Roentgenograms at the final follow-up did not show any problems with the screw or non-union.
