title: Outcome after pelvic sarcoma resection and reconstruction with a modular hemipelvic prostheses.
abstract: OBJECTIVE
  The aim of this study was to evaluate the early clinical outcome of reconstruction with modular hemipelvic prostheses after pelvic sarcoma resection.
  
  
  METHODS
  We retrospectively reviewed eight patients between 2004 and 2007 who had periacetabular resections and reconstruction with a modular hemipelvic prosthetic system for pelvic sarcoma with a mean follow-up of 27 (range,10~54) months. Oncology outcome was assessed with survival rate, local recurrence rate, International Society of Limb Salvage (ISOLS) score and complications. Two patients had types I and II (periacetabular and ilium) pelvic resections, three had types II and III (periacetabular and pubis) pelvic resections and three had type I , II and III (ilium, periacetabular and pubis) pelvic resections. Nobody received chemotherapy or radiotherapy.
  
  
  RESULTS
  Five patients were free of disease; three patients died of disease. The overall survival rate was 62.5%. None had local recurrence, and 37.5% had metastasis. The mean ISOLS score was 19.5. No one had deep infection or dislocation.
  
  
  CONCLUSIONS
  Reconstruction with a modular hemipelvic prosthetic system after periacetabular resection is a promising method because of the acceptable complication rate and satisfactory functional outcome.
