Long-term outcomes of early hip prostheses remain relevant for understanding implant durability and biological fixation. This report describes a 62-year follow-up of a patient who underwent Vitallium mold arthroplasty of the hip, representing one of the longest known survivals of this implant type. Computed tomography demonstrates apparent biological fixation of the cup to the femoral head, offering a rare view of long-term implant-host integration. The case is analyzed in the context of broader clinical experience and literature trends. Findings from this follow-up raise important considerations regarding prosthesis longevity and the potential for lasting biological function in select implant designs.
早期髋关节假体的长期预后对于理解植入物的耐久性和生物固定仍具有重要意义。本报告描述了一名接受维塔利姆（Vitallium）髋关节模具置换术患者的62年随访情况，这是已知该种植体类型存活时间最长的病例之一。计算机断层扫描显示髋臼杯与股骨头之间存在明显的生物固定，提供了长期植入物与宿主整合的罕见景象。结合更广泛的临床经验和文献趋势对该病例进行了分析。此次随访结果引发了关于假体寿命以及特定植入物设计中持久生物功能潜力的重要思考。
