The posterior bone block procedure is a well-known treatment option for posterior shoulder instability. The goal of this retrospective multicenter study was to evaluate the clinical and radiological outcomes of this procedure.
Material and methods
The study cohort consisted of 66 patients (55 men, 11 women) with an average age of 27.8 years who were evaluated clinically and radiologically using a standardized questionnaire after posterior bone block surgery.
The Constant score significantly improved postoperatively (P<0.0001). The postoperative Walch-Duplay score was 81.5. The Rowe score was 86.5 points. The pain level (VAS) was significantly reduced after this procedure (P<0.0001). Eighty-five percent of patients were satisfied or very satisfied with the outcome.
This multicenter study of 66 patients shows that the posterior bone block procedure is an effective technique with good subjective and objective outcomes; however, the possibility of complications cannot be ignored.
