Analysis of the curative efficacy of intraspinal bone decompression by micro-sculpture facet joint transforaminal reduction through the intervertebral foramen in the treatment of thora-columbar burst fractures
Objective To investigate the clinical effect of intraspinal bone decompression by micro-sculpture facet joint trans-foraminal reduction through the intervertebral foramen in the treatment of thoracolumbar burst fractures.Methods A retrospective analysis of 64 patients with thoracolumbar burst fractures with bone mass compression resulting in neurological symptoms from February 2016 to February 2023 at the Department of Xuanhan County People's Hospital was performed.Thirty-two patients who underwent direct decompression reduction of the posterior margin of the vertebral body by micro-sculpting facet joints through paraspinal muscle approach were included in an observation group.Another 32 patients who underwent indirect decompression through laminectomy via laminar approach were involved in a control group.Intraoperative blood loss,operative duration and amount of bone amputation were compared between the two groups.Cobb angle,height ratio of the anterior margin of the injured vertebra,ODI index of dysfunction,VAS score of pain degree and spinal nerve function grade before and after 12 months of treatment were compared between the two groups.Results The amount of blood loss,operation time and bone amputation in the observation group were significantly less or shorter than those in the control group(P＜0.05).After 12 months of surgery,the Cobb angle of injured vertebra in the observation group was significantly lower than that in the control group.The height ratio of anterior margin of injured vertebra was significantly higher than that in the control group.The ODI index and the VAS score in the observation group were obviously lower than those in the control group.The spinal nerve function grade in the observation group was noticeably better than that in the control group.All differences were statistically significant(P＜0.05).Conclusions Compared with conventional laminectomy decompression,micro-sculpted facet joints are used to establish the decompression channel.Thus,it can significantly reduce the bleeding and trauma.It can also improve the vertebral stability,restore the vertebral height,relieve the dysfunction,and improve the spinal nerve function.
