title: The treatment of lumbosacral instability by the Diapason system.
abstract: OBJECTIVE
  To introduce a new internal fixation system of spine and its characteristics.
  
  
  METHODS
  To review 16 patients with lumbosacral instability who were their clinical outcomes and radiographic evaluation.
  
  
  RESULTS
  Fifteen patients gained complete recovery from their preoperative symptoms. One patient who had experienced two operations before and with problems of urinary and fecal incontinence and walking difficulty still had lower limb pain, muscle weakness and urinary incontinence after operation. There is no evidence of spine glide on X-ray, implant failure, neural complication or infection during follow up.
  
  
  CONCLUSIONS
  Diapason system can achieve good early postoperative results with few complications and ease to use for lumbosacral instability.
