Therefore, the present study was conducted to illustrate the QoL for TOLF patients after surgery and determine its relationship with their demographic, surgery\u2010related, clinical characteristics and imaging data.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>One hundred and eighteen patients diagnosed with thoracic myelopathy because of TOLF were enrolled in this retrospective study. They all underwent posterior decompressive laminectomy from August 2010 to January 2022. The QoL was evaluated based on the EQ\u20105D\u20105L. Collecting gender, age, number of operations, compressed segments, Frankel grade, complications, body mass index (BMI), symptoms and duration, modified Japanese Orthopaedic Association (mJOA) score (preoperative), follow\u2010up time and type of ossification, increased signal on Sagittal T2\u2010weighted Images (ISST2I), occupancy rate and analyzing by Mann\u2013Whitney <jats:italic>U<\/jats:italic>\u2010test, Kruskal\u2013Wallis test, the <jats:italic>\u03c7<\/jats:italic><jats:sup>2<\/jats:sup>\u2010test, and logistic regression tests.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Average follow\u2010up 70.8\u2009months (18\u2013149), the mean age was 59.74\u2009\u00b1\u20099.81\u2009years and the mean score for the QoL based on the EQ\u20105D\u20105 L and visual analogue scale (VAS) score were 0.71\u2009\u00b1\u20090.28 and 78.88\u2009\u00b1\u200910.21 at the final follow\u2010up. Moderate and severe problems were found in the pain\/discomfort in 22.0% of the patients. These mobility and usual activities numbers were slightly higher (24.6% and 30.4%, respectively). The mean scores for QoL and VAS were significantly higher in patients with mild and moderate neurological impairment, normal BMI, &lt;60\u2009years of age, no dural tears, symptom relief at hospital discharge, unilateral and bilateral ossification on axial CT scan, \u2264\u200950% spinal canal occupancy on CT and MRI, and none or fuzzy on ISST2I.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>QoL after posterior laminectomy in TOLF patients is generally satisfactory compared to preoperative levels.

Age, spinal canal occupancy rate, ISST2I, preoperative mJOA score, BMI are significantly associated with and have predictive value for overall postoperative
