title: Lumboiliac fixation in lumbosacral dislocation and associated injuries of the pelvis and lumbosacral junction: a long-term radiological and clinical follow-up.
abstract: BACKGROUND
  The goal of the study was to evaluate both clinical and radiological outcome of a consecutive series of 11 patients submitted to lumboiliac fixation after lumbopelvic disjunction or associated injuries of the pelvis and lumbosacral tract in mid- and long-term follow-up.
  
  
  METHODS
  The following were evaluated from clinical charts: damage control preoperative procedures, surgery, and pre-, intra- and post-operative complications; imaging was also evaluated from the preoperative assessment to the final follow-up (4 to 13.2 years; average 7.2 years).
  
  
  RESULTS
  One patient died a few days after surgery; therefore, long-term follow-up was possible in 10 patients. One of the 10 patients could be evaluated only radiologically because he was non-compliant due to severe mental illness. There were four early complications: one patient had a massive pulmonary embolism, which was fatal; one had wound dehiscence; one developed pulmonary infection and one had caecal fistula, which was repaired by the general surgeon. Late complications were as follows: three patients required hardware removal or substitution because of deep infection (after 1year), system breakage (after 9 years) and screws loosening (after 7 years). Clinical evaluation was available in nine patients and was assessed using Oswestry forms and a Visual Analogue Scale (VAS). All patients were able to walk at least 1 kilometre without external support, two patients were using pain medication regularly and three patients were classified with severe disability at final follow-up. Degenerative changes in the joints close to the fused area were observed in two patients more than 10 years after the operation, but the correlation with surgery is questionable.
  
  
  CONCLUSIONS
  Lumbopelvic disjunctions generally follow high-energy trauma often involving internal thoracic and abdominal organs; therefore, a well-trained team approach is mandatory to preserve patient life and to provide adequate treatment of skeletal injuries. Mechanical complications may occur several years after surgery, thus a long-term follow-up is mandatory.
  
  
  CONCLUSIONS
  Lumbopelvic fixation is an effective surgical technique for treatment of spinopelvic disjunction. The patient numbers in this series, and in the literature in general, are low; therefore, a multicentre study is advisable to give evidence and statistical importance to our findings.
