title: [Repair of bone defect due to tumour resection with self-setting calcium phosphate cement in children].
abstract: OBJECTIVE
  To study the effect of self-setting calcium phosphate cement (CPC) on the repair of local bone defects after resection of cyst in children.
  
  
  METHODS
  From December 1998 to May 2002, 22 patients with bone defects were repaired with CPC. Their ages ranged from 4 to 10 years with an average of 8.3 years. There were 11 cases of non-ossifying fibroma, 7 cases of osteoid osteoma, 2 cases of bone cyst and 2 cases of fibrous dysplasia. The bone defects are located as the following: femur in 14 cases, tibia in 6 cases and humerus in 2 cases. CPC spongiosa granules were filled in 11 cases, injectable CPC were filled in 2 bone cyst cases. The patients were followed up for 5-48 months, averaged 23.5 months.
  
  
  RESULTS
  Bone matrix grew well and no recurrence was found.
  
  
  CONCLUSIONS
  The method with simple CPC in repairing bone defects is safe, non-toxic, economic and convenient in children.
