title: Long-term results of hemipelvic allograft: Report of four cases.
abstract: Reconstruction after the excision of pelvic tumors involving the pelvic ring implies difficult problems. Restoration of the function is difficult and an allograft can be one of the possible solutions. Pelvic allograft is recommended by many authors to reconstruct the pelvic ring following extensive resections of bone tumors. Between 1988 and 1989, we performed hemipelvic resection and allograft reconstruction in 4 patients with pelvic sarcomas. The mean age was 42.3 years (range 38-48), consists of 3 male and 1 female. One case developed an infection and one case showed recurrence, both responding to surgical treatment. Outcome in those cases in which surgery was curative to the primary tumor was satisfactory at 10 years follow-up, with a mean total Enneking score of 25.3 (range 24-27) and a good functional result in Merlé D'Aubigne functional score. Despite the limited number of cases presented, our results added to the reported results in the literature led us to consider that allografts are valuable in pelvic reconstructions after en-bloc resections for bone tumors.
