Glenoid bone loss remains a challenge in shoulder arthroplasty. Addressing substantial bone loss is essential to ensure proper function and stability of the shoulder prosthesis and to prevent baseplate loosening and subsequent revision surgery. Current options for creating and shaping glenoid bone grafts include free-hand techniques and simple reusable cutting guides that cut the graft at a standard angle. There is currently no patient-specific device available that enables surgeons to accurately prepare the bone graft and correct glenoid deformity. We present a novel surgical technique using three-dimensional (3D)-printed cutting guides to create a patient-specific bone graft to address glenoid deformity in the setting of reverse shoulder arthroplasty.
肩胛盂骨缺损仍是肩关节置换术中的一项挑战。解决严重的骨缺损对于确保肩关节假体的正常功能和稳定性以及防止基板松动和后续翻修手术至关重要。目前用于制作和塑形肩胛盂骨移植块的方法包括徒手技术和以标准角度切割移植块的简单可重复使用的切割导向器。目前尚无针对患者的设备能够使外科医生准确制备骨移植块并矫正肩胛盂畸形。我们介绍一种新颖的手术技术，使用三维（3D）打印的切割导向器制作针对患者的骨移植块，以解决反向肩关节置换术中的肩胛盂畸形问题。
