title: Allograft-implant composite reconstruction following periacetabular sarcoma resection.
abstract: Ten patients with primary periacetabular sarcomas were treated with internal hemipelvectomy and allograft-implant composite reconstruction. Three patients developed local recurrences, one of which was salvaged with repeat resection. One patient underwent hemipelvectomy for infected wound recurrence. At a mean follow-up period of 25 months (range, 7-85 months; median, 18 months), six of nine patients assessed with the Musculoskeletal Tumor Society functional assessment had satisfactory results, with scores of 21 or better (of a possible 35). Although complications were frequent and functional scores were often limited by the muscle resection required for adequate tumor removal, we remain cautiously optimistic about the early results of this procedure.
