Abstract: Objective To compare the clinical result of posterior short-segment instrumentation combined with vertebral bone grafting and interbody bone grafting in the treatment of Denis type B thoracolumbar burst fractures. Methods Retrospectively analyzed 40 cases of Denis type B thoracolumbar burst fractures in our hospital. They were divided into two groups according to the different operation methods: group of vertebral bone grafting and interbody bone grafting. The data of operation time,blood loss in the two groups were recorded and preoperative, postoperative, at the time of the last follow-up Cobb angle, vertebral and superior intervertebral space height were compared and analyzed. Results All the 40 patients were followed up for 19 months for average. There was significant difference between the two groups in operation time and blood loss(P <0.05). The differences of the Cobb angle, the height of injured vertebral body and the upper intervertebral space were statistically significant before and after operation(P<0.05), there was no difference between postoperation and the end of the follow-up(P>0.05),while the average correction loss of vertebral bone graft group was greater than that of the interbody bone graft group. Conclusion The effect of posterior short-segment fixation combined with interbody bone grafting in the treatment of Denis type B thoracolumbar fracture with intervertebral disc injury is reliable, it can reconstruct the height of vertebral body, restore the support of anterior and middle column and promote the healing of fracture.
