ABSTRACT
STUDY DESIGN: Retrospective study. PURPOSE: To determine if posterior surgery alone can satisfactorily treat post-traumatic kyphosis (PTK). OVERVIEW OF LITERATURE: 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 3.2degrees+/-2.1degrees 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.
