Open\u2010door laminoplasty combined with bilateral lateral mass screw fixation (ODL\u2010BLMSF) is a relatively new surgical technique; however, its clinical effectiveness in managing MCSS\u2010TCISCI has not been well\u2010established. This study aims to assess the clinical value of ODL\u2010BLMSF against MCSS\u2010TCISCI.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>We retrospectively analyzed 20 cases of MCSS\u2010TCISCI treated with ODL\u2010BLMSF from July 2016 to June 2020. Radiographic alterations of all included patients were measured using plain radiographs, CT scans, and MRI scans. Cervical lordosis was evaluated using C2\u2010C7 Cobb angle and cervical curvature index (CCI) on lateral radiographs, and Pavlov ratio at the C5 level. Neurological functional recovery was assessed using Japanese Orthopaedic Association (JOA) scores and Nurick grade, while neck and axial symptoms were assessed using the neck disability index (NDI) and the visual analog scale (VAS).

The average Pavlov ratio at the C5 level significantly improved from 0.57\u2009\u00b1\u20090.1 preoperatively to 1.13\u2009\u00b1\u20090.1 and 1.12\u2009\u00b1\u20090.04 at 6\u2009months postoperatively and at the last follow\u2010up (<jats:italic>t<\/jats:italic>\u2009=\u200916.347, 16.536, <jats:italic>p<\/jats:italic>\u2009&lt;\u20090.001). Importantly, this approach significantly increased the JOA score from 5.0\u2009\u00b1\u20092.6 before surgery to 11.65\u2009\u00b1\u20094.3 and 12.1\u2009\u00b1\u20094.3 at 6 months postoperatively and at the last follow\u2010up (<jats:italic>t<\/jats:italic>\u2009=\u20099.6, \u22129.600, <jats:italic>p<\/jats:italic>\u2009&lt;\u20090.001), with an average JOA recovery rate of 59.1%; and the average Nurick disability score decreased from 3.0\u2009\u00b1\u20091.3 (preoperative) to 1.65\u2009\u00b1\u20091.22 and 1.5\u2009\u00b1\u20091.2 (6\u2009months postoperatively and at last follow\u2010up) (<jats:italic>t<\/jats:italic>\u2009=\u20095.111, 1.831, <jats:italic>p<\/jats:italic>\u2009&lt;\u20090.001).
