title: [Percutaneous vertebroplasty in the treatment of osteoporotic vertebral compression fractures: first short term results].
abstract: OBJECTIVE
  To describe the technique of percutaneous vertebroplasty and the short-term results in patients with symptomatic, osteoporotic vertebral compression fractures.
  
  
  METHODS
  Prospective follow-up study.
  
  
  METHODS
  In a pilot-study to evaluate the short-term safety and effectiveness of percutaneous vertebroplasty, 18 consecutive patients with a total of 33 osteoporotic thoracic or lumbar vertebral compression fractures were treated from October 2001 to June 2002 with a follow-up of 3-6 months. The indication for treatment was a symptomatic, therapy-resistant osteoporotic vertebral compression fracture. Percutaneous vertebroplasty was performed under radiographic control, after previous intraossal venography, using bone cement mixed with barium sulphate. Post-procedural follow-up consisted of radiological evaluation with conventional thoracolumbar X-rays and MRI scans, and interviews of the patients.
  
  
  RESULTS
  Percutaneous vertebroplasty was technically successful in 31 of 33 vertebral fractures (94%), and in 16 of 18 patients (89%). One patient with extreme venous contrast leakage could not be treated. Sixteen patients had less or no pain after treatment. One patient retained thoracolumbar back pain after inadequate cementations and refused further treatment. None of the patients reported aggravation of symptoms following the procedure. Contrast leakage was absent in 18 vertebrae. In 8 vertebrae there was contrast leakage to paravertebral veins. In three of these cases the leakage was so severe that embolisation was performed, with success in one case. In 13 vertebrae, cement leakage to intervertebral and paravertebral spaces and pedicular cement spurs were seen, without clinical consequences. Immediately after the procedure and during follow-up there were no clinically relevant complications.
  
  
  CONCLUSIONS
  Percutaneous vertebroplasty was a technically feasible treatment in these patients with symptomatic, therapy-resistant, osteoporotic vertebral fractures. The first short-term results were comparable with results in the literature. A prospective randomised intervention study will be needed to compare percutaneous vertebroplasty with optimal conservative treatment.
