title: Benign bone tumours in Western Australia, 1972-1996.
abstract: OBJECTIVE
  To review the benign bone tumours accessioned by the Bone Tumour Registry (BTR) of Western Australia (WA) during the years 1972-1996 and to determine the incidence of the more common types.
  
  
  METHODS
  Information was extracted from the Registry database using 58 selected fields.
  
  
  RESULTS
  During the 25 year period, 849 benign tumours were accessioned and incidence rates have been calculated for 86 chondromas, 68 osteoid osteomas, 47 giant cell tumours, 32 chondroblastomas, 15 periosteal chondromas and 13 chondromyxoid fibromas.
  
  
  CONCLUSIONS
  The BTR provides a valuable resource for the study of primary bone tumours. This review has established reliable incidence rates for the six most common benign tumours. Such information is rarely available for benign tumours. It has also disclosed that osteoblastoma is only four times less frequent than osteosarcoma, which is five times higher than published figures from North America.
