Functional results of reversed total prostheses (RTP) have-to a very limited degree-been compared with those of other shoulder prosthesis types. The aim of our study was to compare results of four different types of shoulder prostheses in terms of function, pain, and quality of life (QoL).
Questionnaires were completed by 859 patients with shoulder prostheses registered in the Norwegian Arthroplasty Register. Patients with osteoarthritis (OA), rheumatoid arthritis (RA), or fracture sequela (FS) were included. Symptoms and function were assessed using the Oxford Shoulder Score (OSS, scale 0-48), and the EuroQoL-5D (EQ-5D) was used to assess QoL.
Best functional results were obtained using conventional total prostheses (TPs) and RTPs -mean OSS improvement 18 and 16 units, respectively, vs 11 with hemiprostheses (HPs). For patients with OA, TPs performed best; for those with RA and FS, RTPs performed best; and those with HPs had the worst results in all diagnostic groups. The greatest improvement in QoL was seen in patients with TPs and RTPs.
Conventional TPs provide the best improvement in pain, function and QoL in OA patients; RTPs are superior in patients with RA and FS.
反向全髋关节假体（RTP）的功能结果-在非常有限的程度上-已经与其他肩部假体类型进行了比较。我们研究的目的是比较四种不同类型肩部假体在功能、疼痛和生活质量（QoL）方面的结果。
挪威关节置换登记处登记的 859 名肩部假体患者完成了问卷调查。包括骨关节炎（OA）、类风湿关节炎（RA）或骨折后遗症（FS）患者。使用牛津肩评分（OSS，0-48 分）评估症状和功能，使用欧洲五维健康量表（EQ-5D）评估 QoL。
常规全髋关节假体（TPs）和 RTPs 获得了最佳的功能结果-平均 OSS 改善分别为 18 和 16 个单位，而半髋关节假体（HPs）为 11 个单位。对于 OA 患者，TPs 效果最好；对于 RA 和 FS 患者，RTPs 效果最好；而 HPs 在所有诊断组中效果最差。TPs 和 RTPs 患者的 QoL 改善最大。
常规 TPs 为 OA 患者提供了疼痛、功能和 QoL 的最佳改善；RTPs 在 RA 和 FS 患者中更为优越。
