title: Treatment of symptomatic para-articular intraosseous cysts by percutaneous injection of bone cement.
abstract: OBJECTIVE
  To describe the technique and clinical outcome of percutaneous injection of bone cement in the treatment of symptomatic para-articular intraosseous cysts.
  
  
  METHODS
  Five patients (three men, two women; mean age 35 years) with painful para-articular intraosseous cysts were treated by percutaneous injection of bone cement under combined fluoroscopic and computed tomography (CT) guidance. The lesions were all located in weight-bearing bones, involving the acetabulum, proximal tibia, distal tibia, talus, and calcaneus, respectively.
  
  
  RESULTS
  The average amount of bone cement injected was 2.1 ml (range, 0.6-3.5 ml). Calcium phosphate cement was used in four cases and acrylic cement in one case. There were no immediate or delayed complications. Full pain relief was obtained between 1 and 4 weeks after treatment. All patients made a complete recovery and were pain-free at their last visit.
  
  
  CONCLUSIONS
  Percutaneous injection of bone cement was a safe and efficient technique in the management of symptomatic para-articular intraosseous cysts in our population.
