Background:
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.
Results:
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.
Conclusion:
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.
Clinical Study:
Level of evidence IV.
