Abstract

Purpose: To introduce a novel surgical technique for arthroscopic reduction and double-row bridge fixation using trans-subscapularis tendon portal for anterior glenoid fracture and to evaluate the clinical and radiological outcomes. Methods: A total of 22 patients who underwent arthroscopic reduction and double-row bridge fixation for an acute anterior glenoid fracture were retrospectively evaluated. Arthroscopic surgery was performed using four portals including a trans-subscapularis tendon portal. All patients underwent 3D-CT preoperatively and one day and one year postoperatively to evaluate the fracture fragment size, reduction status, and presence of fracture union. To evaluate the degree of fragment displacement, articular step-off and medial fracture gap were measured using 3D-CT. Clinical outcomes were assessed based on the ASES and Constant scores. Postoperative glenohumeral joint arthritis was evaluated using plain radiographs with the Samilson and Prieto classification. Results: The average preoperative fracture fragment size was 25.9 ± 5.6%. Articular step-off (preoperative: 6.0 ± 3.3 mm, postoperative one day: 1.1 ± 1.6 mm, P < 0.001) and medial fracture gap (preoperative: 5.2 ± 2.6 mm, postoperative one day: 1.9 ± 2.3 mm, P < 0.001) were improved after surgery. On the postoperative one year 3D-CT, 20 patients achieved complete fracture union, and two patients showed partial union. Postoperative glenohumeral joint arthritis was observed in four patients. At the last visit, the ASES score was 91.8 ± 7.0 and the Constant score was 91.6 ± 7.0. Conclusion: Arthroscopic reduction and double-row bridge fixation using a trans-subscapularis tendon portal for acute anterior glenoid fracture achieved satisfactory clinical outcomes and anatomical reduction as demonstrated by a low degree of articular step-off and medial fracture gap. Level of evidence: Level IV.
