Efficacy evaluation of the injured vertebra fixation combined with limited open window decompression in the treatment of thoracolumbar burst fracture

Objective:To explore the clinical effects of the injured vertebra fixation combined with limited open window decompression in the treatment of thoracolumbar burst fractures.Methods:Sixty-five patients with thoracolumbar burst fractures were divided into the observation group(33 cases) and control group(32 cases).The observation group was treated with the injured vertebral internal fixation combined with limited open window decompression,and the control group was treated with across injured vertebral bone graft fixation combined with limited open window decompression.The vertebral stability,motor dysfunction and nerve function between two groups were compared.Results:After 1 and 6 months of treatment,the Cobb angle in observation group was lower than that in control group(P<0.01),and the height of intervertebral space was higher than that in control group(P<0.05).After 1,3 and 6 months of treatment,the Oswestry score in observation group was significantly lower than that in control group(P<0.05~P<0.01).After 1 and 6 months of treatment,the levels of serum neuron specific enolase and soluble S-100 protein in observation group were lower than those in control group(P<0.05 to P<0.01).After 6 months of treatment,the Frankel classification in observation group was better than that in control group(P=0.05).Conclusions:The injured vertebra fixation combined with limited open window decompression can improve the stability of vertebra and neurological function in patients with thoracolumbar burst fracture.
