However, it presents challenges such as intraoperative disorientation, high rates of nerve damage, a steep learning curve, and prolonged surgical times, often occurring during the creation of the operative channel. Furthermore, the undefined safe operational zones under endoscopy continue to pose risks to surgical safety. We aimed to analyse the anatomical data of Kambin\u2019s triangle via CT imaging to define the parameters of the safe operating area for transforaminal posterior lumbar interbody fusion (TPLIF), providing crucial insights for clinical practice.<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Methods<\/jats:title>\n                <jats:p>We selected the L4\u2013L5 intervertebral space. Using three-dimensional (3D), we identified Kambin\u2019s triangle and the endocircle within it, and recorded the position of point \u2018J\u2019 on the adjacent facet joint as the centre \u2018O\u2019 of the circle shifts by angle \u2018\u03b2.\u2019 The diameter of the inscribed circle \u2018d,\u2019 the abduction angle \u2018\u03b2,\u2019 and the distances \u2018L1\u2019 and \u2018L2\u2019 were measured from the trephine\u2019s edge to the exiting and traversing nerve roots, respectively.<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Results<\/jats:title>\n                <jats:p>Using a trephine with a diameter of 8\u00a0mm in TPLIF has a significant safety distance. The safe operating area under the TPLIF microscope was also clarified.<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Conclusions<\/jats:title>\n                <jats:p>Through CT imaging research, combined with 3D simulation, we identified the anatomical data of the L4\u2013L5 segment Kambin\u2019s triangle, to clarify the safe operation area under TPLIF. We propose a simple and easy positioning method and provide a novel surgical technique to establish working channels faster and reduce nerve damage rates. At the same time, according to this method, the Kambin\u2019s triangle anatomical data of the patient\u2019s lumbar spine diseased segments can be measured through CT 3D reconstruction of the lumbar spine, and individualised preoperative design can be conducted to select the appropriate specifications of visible trephine and supporting tools. This may effectively reduce the learning curve, shorten the time operation time, and improve surgical safety.<\/jats:p>\n              <\/jats:sec>","DOI":"10.1186\/s13018-024-04830-9","type":"journal-article","created":{"date-parts":[[2024,6,8]],"date-time":"2024-06-08T00:01:44Z","timestamp":1717804904000},"update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":24,"title":["Transforaminal posterior lumbar interbody fusion microscopic safe operating area: a three-dimensional model study based on computed tomography imaging"],"prefix":"10.1186","volume":"19","author":[{"given":"Wei","family":"Wang","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yukai","family":"Cui","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xiaohao","family":"Sun","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Haoran","family":"Zhang","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Wen","family":"Yin","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xilong","family":"Cui","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Wei","family":"Jiao","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"297","published-online":{"date-parts":[[2024,6,8]]},"reference":[{"issue":"8","key":"4830_CR1","doi-asserted-by":"publisher","first-page":"784","DOI":"10.1177\/2192568218770769","volume":"8","author":"VM Ravindra","year":"2018","unstructured":"Ravindra VM, Senglaub SS, Rattani A, Dewan MC, H\u00e4rtl R, Bisson E, et al.
