Recurrent Shoulder Instability With Glenoid Bone Loss: A Case Report on Congruent Arc Latarjet

Year: 2025

Type: article

Abstract: Recurrent shoulder instability is challenging and is linked to significant bony defects such as glenoid bone loss and Hill-Sachs lesions (HSLs). The Latarjet procedure, particularly its congruent arc modification, provides a dependable solution for complex cases with combined glenoid and humeral bone loss. We report the case of a 23-year-old wrestler with recurrent left shoulder dislocations over seven years, severely impairing his daily activities. Clinically, there was a positive apprehension test and limited external rotation. Imaging showed a large HSL and an inverted pear-shaped glenoid, indicating marked bone loss. Glenoid track (GT) analysis confirmed an off-track lesion with high engagement risk. After diagnostic arthroscopy confirmed the bone loss, an open congruent arc Latarjet (CAL) procedure was performed via a deltopectoral approach. The coracoid graft was fixed with two parallel screws, and postoperative radiology verified proper placement. At three months, the patient regained full, pain-free motion without recurrence or functional limitation. This case highlights the importance of early bone loss recognition, accurate imaging, and meticulous planning. The CAL remains an effective option for restoring stability in high-demand patients.
