A 62-Year Follow-Up of Vitallium Cup Arthroplasty: A Case Report and Review of Longevity in Historical Context.

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.
