Comparison of small-incision extreme lateral interbody fusion and minimally invasive transforamen interbody fusion for lumbar degenerative diseases / 中国组织工程研究

ABSTRACT

BACKGROUND: Small-incision extreme lateral interbody fusion and minimally invasive transforamen interbody fusion are widely used to treat patients with lumbar degenerative diseases because of easy operation technology and less serious complications. However, for patients with lumbar degenerative diseases who meet the indications of both surgical methods, how to choose surgical methods needs further study. OBJECTIVE: To compare the clinical outcome between small-incision extreme lateral interbody fusion and minimally invasive transforamen interbody fusion in patients with lumbar degenerative diseases. METHODS: Seventy-six patients with single-segment lumbar degenerative diseases treated from June 2016 to December 2017 were retrospectively analyzed. The patients were divided into small-incision extreme lateral interbody fusion group and minimally invasive transforamen interbody fusion group. Operation time, intraoperative blood loss, postoperative visual analogue scale, Oswestry dysfunction index, Japanese Orthopedic Association score, complications, anterior convex angle of lumbar fusion segment, intervertebral height and intervertebral displacement were compared between the two groups. RESULTS AND CONCLUSION: (1) Operation time and intraoperative blood loss were better in the small-incision extreme lateral interbody fusion group than in the minimally invasive transforamen interbody fusion group (P 0.05). (4) At the last follow-up, the anterior convex angle of fusion segment was larger in the small-incision extreme lateral interbody fusion group than in the minimally invasive transforamen interbody fusion group. The intervertebral height of fusion segment was higher in the small-incision extreme lateral interbody fusion group than in the minimally invasive transforamen interbody fusion group (P 0.05). (5) Both small-incision extreme lateral interbody fusion and minimally invasive transforamen interbody fusion can treat lumbar degenerative diseases effectively. Small-incision extreme lateral interbody fusion is superior to minimally invasive transforamen interbody fusion in terms of operation time, intraoperative blood loss and maintaining the anterior convex angle and intervertebral height of lumbar fusion segment, but incidence of complications is higher.
