Fracture of the anterior glenoid rim along the sites of suture anchor insertion is not rare after arthroscopic Bankart repair for traumatic anterior shoulder instability. In addition to the influence of the number, type, and size of the suture anchors, placing multiple anchors in a linear arrangement might impose excessive stress on the surrounding bone, leading to critical loss of osseous integrity and glenoid fracture. Although highly active young male collision or contact athletes are most at risk, such fractures sometimes occur after relatively minor trauma at a long interval after surgery, suggesting persistent impairment of bone quality. In patients with postoperative recurrence of instability, detailed examination using computed tomography is recommended.
关节镜下 Bankart 修复治疗外伤性肩关节前脱位后,前肩盂唇骨缝合锚钉插入处的前肩盂唇骨骨折并不少见。除了缝合锚钉的数量、类型和大小的影响外,线性排列多个锚钉可能会对周围骨骼施加过大的压力,导致骨完整性严重丧失和肩盂骨折。虽然高活动度的年轻男性碰撞或接触运动员风险最大,但此类骨折有时在手术后较长时间间隔发生轻微创伤后也会出现,提示骨质量持续受损。对于术后不稳定复发的患者,建议使用计算机断层扫描进行详细检查。
