title: Intermediate results of a cemented femoral stem with a PMMA premantle.
abstract: This retrospective study evaluated the intermediate clinical results ot a series of 143 patients after total hip arthroplasty using the Definition PM femoral component. One hundred twenty-two patients had a mean follow-up of 5 years (range, 23-77 months), died (mean 30 months; range, 6-56 months), or were revised (mean 20 months; range, 9-40 months). The mechanical failure rate of the femoral stem was 0.8% for those patients with an average 5-year follow-up. Radiographic examination revealed that 1 (0.8%) femoral component was possihly loose, while none had evidence of dehonding. Follow-up radiographs revealed 2.50% (anteroposterior) and 5% (lateral) of the femoral components to have radiolucencies at the cement-bone interface. At a mean of 5 years. 2 of the 122 femoral romnonents imnlanted renuired revision.
