Effect of Different Approach Decompression and Internal Fixation on Spinal Canal Occupying Rate and Nerve Function in Patients with Thoracic and Lumbar Spine Bursting Fracture
Objective:To compare the effect of different approach decompression and internal fixation on spinal canal occupying rate and nerve function in patients with thoracic and lumbar spine bursting fracture.Method:A total of 80 patients with thoracic and lumbar spine bursting fracture admitted to Xiamen Hospital of TCM from January 2019 to January 2023 were selected as the study objects,and were divided into posterior median group and paravertebral muscle group according to different surgical approaches,with 40 cases in each group.The posterior median group was treated with posterior median approach decompression and internal fixation,and the paravertebral muscle group was treated with transparavertebral muscle space approach decompression and internal fixation.The surgical indexes,vertebral compression ratio,kyphotic Cobb angle,activities of daily living scale(ADL)score,visual analogue scale(VAS)score,spinal canal occupying rate and spinal nerve function grade were compared between the two groups.Result:The operation time of paravertebral muscle group was shorter than that of posterior median group,and the intraoperative blood loss was less than that of posterior median group(P<0.05).There were no significant differences in hospital stay and after surgery of vertebral compression ratio,kyphotic Cobb angle,spinal canal occupying rate and spinal nerve function grade between the two groups(P>0.05).The ADL score of paravertebral muscle group after surgery was higher than that of posterior median group,and the VAS score was lower than that of the posterior median group(P<0.05).Conclusion:Both the posterior median approach and the transparavertebral muscle space approach decompression and internal fixation can effectively restore the vertebral height in patients with thoracic and lumbar spine bursting fracture,reduce the kyphotic Cobb angle and spinal canal occupying rate,and improve spinal nerve function.However,the transparavertebral muscle space approach has the advantages of short time,less intraoperative bleeding,and less postoperative pain.
