The demographic and radiological data of the two groups were analyzed and compared.<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Results<\/jats:title>\n                <jats:p>A total of 64 patients were finally recruited in this study. There were no significant differences in gender, age, follow-up time, injury mechanism, injury level, AO classification, American Spinal Injury Association (ASIA) score, visual analogue scale (VAS) score, and duration of hospital stay between the two groups (<jats:italic>P<\/jats:italic>\u2009&gt;\u20090.05). After the procedures, the prevertebral height ratio (PHR), the Cobb angle, and the mid-sagittal canal diameter compression ratio (MSDCR) were significantly improved (<jats:italic>P<\/jats:italic>\u2009&lt;\u20090.05) in both groups. However, group A demonstrated less intraoperative bleeding and a greater VAS score improvement postoperatively and at the last follow-up but involved a longer operation time (<jats:italic>P<\/jats:italic>\u2009&lt;\u20090.05). The PHR and the Cobb angle in the two groups showed no significant difference postoperatively and at the last follow-up (<jats:italic>P<\/jats:italic>\u2009&gt;\u20090.05). In contrast, a significant improvement in MSDCR was observed at the last follow-up when compared with the postoperative value (<jats:italic>P<\/jats:italic>\u2009&lt;\u20090.05). However, the Cobb angle in group A was better maintained than in group B at the last follow-up (<jats:italic>P<\/jats:italic>\u2009&lt;\u20090.05), while the MSDCR in group B demonstrated a greater improvement at the last follow-up than in group A (<jats:italic>P<\/jats:italic>\u2009&lt;\u20090.05).<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Conclusions<\/jats:title>\n                <jats:p>Both the MOT and traditional open surgery are effective treatment options for AO type A3 and A4 thoracolumbar burst fractures with severe traumatic spinal stenosis. The advantages of MOT include the minimally invasive procedure, extremely fine spinal canal decompression, less intraoperative bleeding, and significant pain relief. We suggest that MOT should be preferentially performed for AO type A3 or A4 thoracolumbar burst fractures with severe traumatic spinal stenosis.<\/jats:p>\n              <\/jats:sec>","DOI":"10.1186\/s13018-022-03412-x","type":"journal-article","created":{"date-parts":[[2022,12,1]],"date-time":"2022-12-01T18:16:00Z","timestamp":1669918560000},"update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["A comparative study on efficacies of posterior microscopic mini-open and open technique for thoracolumbar burst fractures with severe traumatic spinal stenosis"],"prefix":"10.1186","volume":"17","author":[{"given":"Bin","family":"Zhang","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yanna","family":"Zhou","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hua","family":"Zou","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zimo","family":"Lu","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xin","family":"Wang","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5658-8806","authenticated-orcid":false,"given":"Jun","family":"Ao","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"297","published-online":{"date-parts":[[2022,12,1]]},"reference":[{"key":"3412_CR1","doi-asserted-by":"publisher","first-page":"532","DOI":"10.1186\/s13018-020-02075-w","volume":"15","author":"J Huang","year":"2020","unstructured":"Huang J, Zhou L, Yan Z, Zhou Z, Gou X.
