title: [Analysis of long-time construct failure of spinal surgery in patients with Parkinson's disease].
abstract: OBJECTIVE
  To assess the rate of complications of spine surgery and the therapeutic efficacy in the patients with Parkinson's disease (PD) and characterize the special needs of this unique population.
  
  
  METHODS
  The data of 25 PD patients undergoing the spinal surgery from January 1998 to December 2006 were analyzed. The patients not followed on a regular basis by their spine surgeons were invited for a follow-up review. The points of analysis were complications, revisions and reasons of surgery failure.
  
  
  RESULTS
  The mean follow-up period was 56.3 months. Of 25 patients, 20 (80%) required additional surgery for a total of 25 reoperations. Three patients in need of additional surgery underwent another operation at a remote spinal segment. And 17 patients had the reoperations because of segmental instability at the operated or adjacent levels.
  
  
  CONCLUSIONS
  The PD patients undergoing spine surgery have a high reoperation rate associated with technical complications. They should be appropriately counseled regarding an increased risk of operative complications. A closely follow-up is essential.
