title: Posterior Surgery Alone in the Treatment of Post-traumatic Kyphosis by Posterior Column Osteotomy, Spondylodesis, Instrumentation, and Vertebroplasty.
abstract: METHODS
  Retrospective study.
  
  
  OBJECTIVE
  To determine if posterior surgery alone can satisfactorily treat post-traumatic kyphosis (PTK).
  
  
  BACKGROUND
  One of the worst complications of vertebral fractures is PTK. The type of surgery and approach to treat a symptomatic and refractory PTK is a challenging issue in spinal surgery, and yet, there is no specific treatment algorithm.
  
  
  METHODS
  From August 2003 to September 2010, we collected 26 cases (male to female ratio, 2.25; mean age, 31.9±9.7 years and follow-up period of 42.4±8.1 months) with PTK treated by posterior column osteotomy, spondylodesis, instrumentation and cement vertebroplasty in one stage posterior surgery. PTK angle, Oswestry Disability Index (ODI), visual analogue scale (VAS), and subjective satisfaction from surgery were used to determine the results. We used a student t test for analyzing the data before and after surgery.
  
  
  RESULTS
  In our patients, T11 and L1 had the highest incidence of vertebral fractures. The results indicated that in PTK, ODI, and VAS were significantly improved this surgery. Solid fusion occurred in 96.2% of patients with 3.2°±2.1° loss of correction. A total of 84.6% of patients have satisfaction level of excellent and good.
  
  
  CONCLUSIONS
  Posterior surgery alone with posterior column osteotomy, vertebroplasty, posterior spinal fusion and instrumentation can effectively treat symptomatic PTK.
