Abstract:
While several proximal humerus fractures treated nonsurgically reach satisfactory outcomes, some become symptomatic malunions or nonunions with pain and dysfunction. When joint-preserving options such as malunion or nonunion repair are not optimal because of poor remaining bone stock or glenohumeral arthritis, shoulder arthroplasty is a good option. Because of the semiconstrained design of reverse shoulder arthroplasty, it is effective at improving function when there is notable bony deformity or a torn rotator cuff. Clinical studies have demonstrated reliable outcomes, and a classification system exists that is helpful for predicting prognosis and complications. By understanding the associated pearls and pitfalls and with careful management of the tuberosities, reverse shoulder arthroplasty is a powerful tool for managing proximal humerus fracture sequelae.
摘要:
虽然几个肱骨近端骨折非手术治疗达到满意的结果,一些患者会出现症状性的不愈合或不愈合,伴有疼痛和功能障碍。当由于剩余的骨量差或肱骨关节炎而导致诸如畸形愈合或不愈合修复等关节保留选项不是最佳选择时,肩关节成形术是一个很好的选择。由于反向肩关节置换术的半约束设计,当出现明显的骨畸形或肩袖撕裂时,可有效改善功能。临床研究已经证明了可靠的结果,并且存在有助于预测预后和并发症的分类系统。通过了解相关的珍珠和陷阱,并仔细管理结节,反向肩关节置换术是治疗肱骨近端骨折后遗症的有力工具。
