Abstract:Objective To investigate the clinical effect of posterior interbody fusion and intervertebral foramen fusion in the treatment of degenerative lumbar spondylolisthesis with vertebral fracture. Methods From January 2011 to December 2015, in Department of Orthopedics, Dongtai People's Hospital, the clinical data of 120 patients with vertebral fracture degeneration lumbar spondy lolisthesis were analyzed retrospectively. according to the operation method they were divided into observation group and control group, 60 cases with posterior interbody fusion were as control group, and 60 cases with intervertebral foremen fusion were as observation group. The operative time, hospitalization cost and intraoperative blood loss of the two groups were compared. 1 year after operation, the JOA scores were compared, the X-ray films were regularly reviewed to observe the fusion and lumbar stability. Results The operation time, intraoperative blood loss and hospitalization cost were in the observation group lower than those in the control group, the differences were statistically significant (P < 0.05). The ODI of the observation group was lower than that of the control group, the difference was statistically significant (P <0.05). There was no significant difference of fusion rate between the two groups (P > 0.05). There was no significant difference in vertebral activity and translucent band width between the two groups (P > 0.05), but the average height of the intervertebral space of control group was lower than that of the observation group, the difference was statistically significant (P <0.05). In the control group, there were 2 cases of cerebrospinal fluid leakage, which was related to the separation of scar adhesions during operation. During the follow-up, there was no dislocation of the fusion, sinking and nail bar loosening, and the fracture occurred. No infection in both groups. Conclusion Intervertebral forumen fusion is superior to lumbar spondylolisthesis in patients with lumbar spondylolisthesis. The clinical effect is satisfactory, the stability of lumbar vertebra is good and the fusion rate is high. It is worthy of clinical application.
