title: Endoprosthetic replacement of diaphyseal bone defects. Long-term results.
abstract: We retrospectively studied 35 patients who underwent endoprosthetic reconstruction of diaphyseal bone defects after excision of primary sarcomas. The patients were treated between February 1979 and May 1999 and had more than 5 years follow-up. There were 22 males and 13 females and the median age at diagnosis was 29 (8-75) years. The bone defect measured a mean of 19 (10-27.6) cm. There were 29 femoral reconstructions, three tibial and three humeral. Cumulative overall survival for all patients was 65% at 10 years. Cumulative overall survival for prosthetic reconstruction, using revision surgery as an end point, was 63% at 10 years. Cumulative risk of failure of reconstruction, including infection, fracture, aseptic loosening, local recurrence and amputation, was 60% at 10 years. Tibial and humeral reconstructions fared less well than femoral. Endoprosthetic replacement is a useful method of reconstructing long intercalary defects, especially if situated in the femur.
