title: Safety and effectiveness of percutaneous sacroplasty: a single-centre experience in 58 consecutive patients with tumours or osteoporotic insufficient fractures treated under fluoroscopic guidance.
abstract: OBJECTIVE
  To report our experience in percutaneous sacroplasty (PSP) for tumours and insufficiency fractures of the sacrum.
  
  
  METHODS
  Single-centre retrospective analysis of 58 consecutive patients who underwent 67 PSPs for intractable pain from sacral tumours (84.5 %) or from osteoporotic fractures (15.5 %). The following data were assessed: visual analogue scale (VAS) before and after the procedure for global pain; short-term (1-month) clinical follow-up using a four-grade patient satisfaction scale (worse, unchanged, mild improvement and significant improvement); modification in analgesics consumption; referred short-term walking mobility. Minor and major complications were systematically assessed.
  
  
  RESULTS
  The mean VAS score was 5.3 ± 2.0 in pre-procedure and 1.7 ± 1.8 in post-procedure. At 1-month follow-up, 34/58 (58.5 %) patients experienced a mild improvement; 15/58 (26 %) presented a significant improvement while 4/58 (7 %) and 5/58 (8.5 %) patients had unchanged or worse pain, respectively. Decreased analgesic consumption was observed in 34 % (20/58) of the patients. Eighty percent of patients with walking limitation experienced improvement, 16 % remained unchanged and 4 % were worse. We noted minor complications in 2/58 patients (3.4 %) and major complications in 2/58 patients (3.4 %).
  
  
  CONCLUSIONS
  Percutaneous sacroplasty for metastatic and osteoporotic fractures is a safe and effective technique in terms of pain relief and functional outcome.
  
  
  CONCLUSIONS
  • Percutaneous sacroplasty provides pain relief and functional improvement for insufficiency sacral fractures. • Percutaneous sacroplasty provides pain relief and function improvement for sacral tumours. • The major complication rate is acceptable (3.4 %), and is higher in sacral tumours. • Posterior wall/cortical sacral bone disruption is not statistically associated with more complications. • However, osteolytic tumours seem to be associated with higher risk of complications.
