With a mean follow-up of 62 months, we reviewed 13 Kudo type 4 and 23 Kudo type 5 elbow prostheses implanted for non-traumatic indications in 30 patients. Clinical results were assessed with the Mayo Clinic Performance Index (MCPI) taking into account pain, mobility, stability and daily activities. Postoperatively, pain disappeared or decreased, ulnar nerve dysfunction was improved and the functional status was significantly improved. The average range of motion increased by 7.8 degrees in extension and by 11.5 degrees in flexion; pronation and supination remained unchanged. Clinically, 89% of patients scored poorly on the MCPI preoperatively, whereas 61% had excellent or good scores postoperatively. Twenty-two patients out of 30 were satisfied. There were two early prosthetic dislocations, and prosthetic instability, assessed clinically, was found in 6 cases (17%). The rate of loosening was 28% (10/36) and seven elbows were revised. Metallosis, loosening and instability were significantly correlated. The survival rate of 82% at 54 months (SD = 7) is lower than that reported for non-constrained and semi-constrained prostheses in the literature.
平均随访62个月，我们回顾了为30例患者植入的13个Kudo 4型和23个Kudo 5型肘关节假体，这些假体用于非创伤性适应症。采用梅奥诊所功能指数（MCPI）评估临床结果，该指数考虑了疼痛、活动度、稳定性和日常活动情况。术后，疼痛消失或减轻，尺神经功能障碍得到改善，功能状态显著改善。平均活动范围在伸展时增加了7.8度，在屈曲时增加了11.5度；旋前和旋后保持不变。临床上，89%的患者术前MCPI评分较差，而术后61%的患者评分优秀或良好。30例患者中有22例满意。发生了2例早期假体脱位，临床评估发现6例（17%）存在假体不稳定。松动率为28%（10/36），7个肘关节进行了翻修。金属沉着症、松动和不稳定之间存在显著相关性。54个月（标准差=7）时82%的生存率低于文献中报道的非限制性和半限制性假体的生存率。
