Objective: Evaluation of long-term clinical effects for treatment of thoracolumbar fractures by fractured vertebral posterior pedicle bone graft molding combined four nails fixing.Methods: 56 cases of thoracolumbar fractures by surgical treatment were enrolled in our hospital since January 2004-January 2011.Comparing Indicators of vertebral body shape and Frankel score of two groups, which are group A with fractured vertebral posterior pedicle bone graft molding combined four nails for fixing and group B with the traditional four nails fixing, before surgery,after surgery and long-term removal of implants after surgery.Results: Followed-up cases of removing internal fixation in second phase and cases of implanting and before removing internal fixation in first phase of group A.The contrast between vertebral height compression rate of loss and kyphosis Cobb angle change was not statistically significant. The injured vertebral changes differences was statistically significant by contrast between group A cases of removing internal fixation in second phase and group B cases after removing the fixture in second phase.Conclusion: Long-term effects of thoracolumbar fractures by fractured vertebral posterior pedicle bone graft molding is stable in comparison with four-nails fixing.There is no case of internal fixation loose and broken. Bone strength is close to normal but not dependent on pedicle screw after fracture healing.
