title: The swing procedure for pelvic ring reconstruction following tumour excision.
abstract: OBJECTIVE
  High grade periacetabular osteosarcomas extending to the sacro-iliac region present a difficult management problem. We describe our experience of the swing procedure as a method of limb salvage.
  
  
  METHODS
  The procedure was performed on three patients with stage II B osteosarcoma.
  
  
  RESULTS
  Functional outcome was poor in all three with a mean Musculoskeletal Tumor Society score of 29% (27-30) at last review. All three developed local recurrence and one developed pulmonary metastases. The mean disease free interval post-operatively was 4.7 months (4-6) and they died of their disease at a mean of 10 months (5-16).
  
  
  CONCLUSIONS
  This form of limb salvage is technically demanding and carries a high morbidity. Functional outcome is poor and the prognosis for this group of patients is not improved by surgery. Alternative treatment options are discussed.
