Early Clinical outcomes of reconstruction of glenoid bone loss with distal clavicle autograft (DCA) bone block in patients with Recurrent Anterior Shoulder Dislocation.

Abstract Purpose: Glenoid bone loss has emerged as one of the most significant risk factors for recurrence after arthroscopic treatment of glenohumeral instability There are Many Bony augmentation procedures to reconstruct glenoid bone loss , Technical Notes and anatomic studies describing the reconstruction of glenoid bone lossusing a distal clavicle autograft (DCA) were recently published. The aim of this study is to assess the early clinical outcomes and re-dislocation rate after glenoid reconstrction by distal clavicle autograft Methods: this a case series study, included 20 patients with recurrent shoulder dislocstion with glenoid bone loss operated by distal clavicle autograft bone block betweenApril, 2023, to may, 2024. All patients were preoperatively subjected to detailed History talking; Complete Clinical examination, Full Imaging investigations with 3D- CT with glenoid enface view and MRI. and preoperative and final postoperative follow up Scoring and Full Imaging investigations with 3D- CT with glenoid enface view and MRI. ROWE, Constant, The visual analog scale for pain ( VAS) and modified patient satisfactory scores. Results: At the final follow-up, the mean and individual functional scores had significantly improved in all patients. The mean Rowe, constant, and VAS scores were 90, 94.5,87.1, and 1.2 respectively. 40% patients were very satisfied, 30% were satisfied, 20% neutral, while 10% patients were dissatisfied at the end of the study. Conclusion: In general, our results showed that distal clavicle auto graft is an effective surgical option for patients with recurrent anterior shoulder dislocation with improvement of post operative patient outcomes
