Total elbow arthroplasty (TEA) with the GSB III prosthesis was performed in 32 patients (36 elbows) with rheumatoid arthritis between 2001 and 2009. At final follow-up, 31 patients (35 TEAs) were available for clinical and radiological evaluation. The mean follow-up period was 6.3 (2.0-10.3) years, with a minimum follow-up of 2 years. The mean Mayo elbow performance score was significantly improved from 48 points preoperatively to 83 points at final follow-up. The radiographic loosening rate was 14.3% for humeral components and 5.7% for ulnar components. There were 4 cases of intraoperative fracture and 1 case of humeral shaft fracture at 4 months after surgery. The rates for loosening and fracture were relatively low when compared with those in other studies of linked TEA. There were 2 cases of ulnar nerve palsy, but there was no deep infection or triceps disruption. The clinical results of TEA using the GSB III prosthesis in patients with rheumatoid arthritis were found to be satisfactory.
2001 年至 2009 年间，32 例（36 肘）类风湿关节炎患者接受了 GSB III 假体全肘置换术。最终随访时，31 例（35 个 TEA）患者可进行临床和影像学评估。平均随访时间为 6.3（2.0-10.3）年，随访时间至少为 2 年。Mayo 肘部功能评分从术前的 48 分显著提高到最终随访时的 83 分。肱骨组件的放射松动率为 14.3%，尺骨组件的松动率为 5.7%。术中骨折 4 例，术后 4 个月肱骨干骨折 1 例。与其他相关 TEA 的研究相比，松动和骨折的发生率相对较低。有 2 例尺神经麻痹，但无深部感染或三头肌断裂。GSB III 假体在类风湿关节炎患者中的全肘置换术的临床效果令人满意。
