The Neuflex silicone metacarpophalangeal (MCP) joint replacement has previously been shown to provide improved movement, particularly flexion, when compared with the Swanson implant. In this study, we reviewed the outcome of 237 Neuflex implants in 66 patients with a follow-up of up to 7 years. Kaplan-Meier analysis using revision as the end stage revealed survival at 7 years to be 88%. If however an implant fracture, as seen radiographically, is taken as the end point, the survivorship drops to 68% at 7 years. These figures are comparable with a similar analysis for the Swanson implant. We conclude that the improved range of motion of the Neuflex implant demonstrated previously does not result in either a higher or a lower revision or implant fracture rate when compared with the Swanson implant.
与Swanson植入物相比，Neuflex硅酮掌指（MCP）关节置换术先前已被证明能改善活动度，尤其是屈曲。在本研究中，我们回顾了66例患者237个Neuflex植入物的结果，随访时间长达7年。以翻修为终点的Kaplan-Meier分析显示，7年生存率为88%。然而，如果将影像学上可见的植入物骨折作为终点，则7年生存率降至68%。这些数字与对Swanson植入物的类似分析结果相当。我们得出结论，与Swanson植入物相比，先前证明的Neuflex植入物改善的活动范围并未导致更高或更低的翻修率或植入物骨折率。
