ABSTRACT
Objective:To investigate the efficacy of shoulder arthroscopic balance point compaction with cross suture-bridge technique inr the treatment of avulsion fracture of the greater tuberosity of the humerus.Methods:A retrospective case series study was conducted on 14 patients with avulsion fracture of the greater tuberosity of the humerus treated in Affiliated Xinhua Hospital of Dalian University from March 2021 to March 2022, including 8 males and 6 females; aged 30-58 years [(40.2±10.5)years]. Among them, 5 patients had fracture in the left shoulder and 9 in the right shoulder. The fracture was classified as the avulsion type according to Mutch classification. All the patients were treated with shoulder arthroscopic balance point compaction with cross suture-bridge technique. The anteroposterior X-ray of the shoulder joint was taken at 1 week, 3 months, and 6 months after surgery to evaluate fracture reduction and fixation. The operative time and intraoperative blood loss were recorded. Fracture healing was evaluated by shoulder MRI at 6 months after surgery. The visual analog score (VAS), Constant shoulder joint score, American Shoulder and Elbow Surgeons (ASES) score, and shoulder range of motion (active abduction angle, active lateral external rotation angle, and active lateral internal rotation) preoperatively, at 3, 6 months after surgery and at the last follow-up were compared. The postoperative complications were observed.Results:All the patients were followed up for 12-15 months [(12.5±0.8)months]. The operative time and intraoperative blood loss were (67.0±10.5)minutes and (20.0±3.8)ml. The anteroposterior X-ray of the shoulder joint showed good reduction and fixation at 1 week, 3 months and 6 months after surgery. MRI T1 image at 6 months after surgery showed locally evenly distributed high signal, suggesting that the fracture was healed well. The values of VAS were (3.2±0.4)points, (2.5±0.5)points, and (0.7±0.3)points at 3, 6 months after surgery and at the last follow-up, which were lower than (7.2±0.6)points preoperatively; the values of Constant joint shoulder score were (53.2±5.3)points, (81.1±4.4)points, and (92.8±5.3)points, which were higher than (42.3±7.6)points preoperatively; the values of ASES score were (55.6±3.6)points, (77.1±3.2)points, and (90.8±3.5)points, which were higher than (45.8±4.2)points preoperatively; the active abduction angles were (60.5±2.5)°, (107.8±6.6)°, and (168.5±3.5)°, which were higher than (18.3±3.3)°preoperatively; the active lateral external rotation angles were (25.8±2.5)°, (30.8±2.2)°, and (63.8±2.8)°, which were higher than (15.6±3.2)°preoperatively ( P<0.05 or 0.01). The level of active internal rotation was L 5, L 1, and T 10, which was better than S 3 before surgery. The VAS, Constant shoulder joint score, ASES score, active abduction and active external rotation were significantly improved at the last follow-up compared with those at 3, 6 months after surgery (all P<0.05), with markedly improved level of active internal rotation. No major complications such as infection, instability of the shoulder joint or acromial impingement were found after surgery. Conclusion:Shoulder arthroscopic balance point compaction with cross suture-bridge technique for the treatment of avulsion fracture of the greater tuberosity of the humerus has advantages of decreased intraoperative blood loss, good reduction and healing, shoulder pain relief, early restoration of shoulder function and mobility, and few complications.
