Clinic Study Of Treatment Of Thoracolumbar Fractures (TLF)fixed With Short-segment Pedicle Instrumentation(SSPI) And Vertebroplasty With Injectable Calcium Sulfate (ICS)

Objective: To determine the medium-term efficiency of short-segment pedicle instrumentation(SSPI) and vertebroplasty with injectable calcium sulfate(ICS) in treatment of thoracolumbar fractures.Methods: From 2007.02 to 2008.08, 38 patients (Group 1) with thoracolumbar fractures were treated with SSPI and vertebroplasty with ICS, while 18 patients (Group 2) with SSPI only. The clinical and radiographic data were recorded and analyzed.Results: For at least 2 years of follow-up, the scores of VAS, Cobb angle and anterior vertebral height of patients in two groups were significantly different at the final follow-up( p<0.01). However, posterior vertebral height was no significant difference between the two groups( p=0.84).Conclusion: For medium-term follow up, fixed with SSPI and vertebroplasty with ICS is an effective treatment to patients with thoracolumbar fracture.It can achieve and maintain kyphosis correction, reduce the instrument failure rate and provide relatively good clinical function outcomes.
