In particular, the axial torque on the spine has been studied in AIS, but not after surgical correction. Spinal axial torque was studied in AIS before and after surgery.nnMETHODS: All AIS (Lenke 1 and 3) who underwent posterior spinal fusion surgery at our center in 2019 were included retrospectively. AIS underwent frontal and sagittal biplanar radiographs in the free-standing position before surgery, 4 months after surgery, and at the last follow-up. Their spine and external envelope were reconstructed with validated methods. Spinal axial torque at the apex and the upper and lower end vertebra was calculated. Finally, the preoperative and postoperative values were compared to a previously published reference corridor for asymptomatic subjects.nnRESULTS: Twenty-nine patients were included (54 ± 11° Cobb angle, 15 ± 2 years old at surgery). The surgical procedure decreased the Cobb angle by 36° ± 11° and decreased the spinal axial torque at the upper end vertebra by 2.5 N/m (95% CI = [1.9; 3]; p < 0.001), at the apex by 0.6 N/m (95% CI = [0.4; 1]; p = 0.004), at the lower end vertebra by 2 N/m (95% CI = [1.5; 2.8]; p < 0.001). Compared to 95th percentile of torque, which was previously evaluated in asymptomatic subjects, more than 90% of patients had higher values at the upper and lower end vertebrae before surgery. Postoperatively, 62% of patients still had higher torque at the upper end vertebra than asymptomatic subjects, while only 38% patients showed abnormal values at the lower junction.nnCONCLUSION: Results of this study confirm that AIS patients show abnormally high spinal axial torque, especially at the end vertebrae, and that this parameter is normalized postoperatively for only a small number of patients.},

The included patients who underwent HGT were compared (complications rate and radiographic parameters) to patients who did not undergo traction (noHGT). For patients who underwent HGT, a spinal front X-ray at the end of the traction procedure was performed.nnRESULTS: Sixty-four in noHGT and forty-seven in HGT group were analyzed with a 31-month mean follow-up. The mean ratio of Cobb angle correction was 58.8% in noHGT and 63.6% in HGT group (p = 0.023). In HGT, this ratio reached 9% if the traction lasted longer than 30 days (p = 0.009). The complication rate was 11.7% with a rate of 6.2% in noHGT and 19.1% in HGT group (p = 0.07). In patient whose preoperative Cobb angle was greater than 90°, the mean ratio of Cobb angle correction increases to 6.7% (p = 0.035) and the complications rate increased to 14% in the no HGT group and decreased to 13% in the HGT group (p = 0.9).nnCONCLUSION: HGT preparation in the management of correction of AIS with a Cobb angle greater than 90° is a technique providing a greater frontal correction gain with similar complication rate than PSF correction alone.

The sitting posture improved in all cases. Twenty-nine patients (17%) had a postoperative infection: twenty-six were treated with local debridement and antibiotics, and three required hardware removal. Fourteen mechanical complications (8%) occurred: screw malposition ( = 6), skin prominence ( = 1), and connector failure ( = 1). This type of surgery is associated with a high risk for infection. Comorbidities, rather than the surgery itself, were the main risk factors that led to complications. The ilio-sacral screw was reliable and effective in correcting pelvic obliquity in NMS patients. The introduction of intraoperative navigation should minimize the risk of screw misplacement and facilitate revision or primary fixation.},

The prevalence of sleep apnoea syndrome was high with 6 out of 8 patients having mild-to-severe sleep apnoea. Patients with severe sleep apnoea syndrome (3 patients) were treated with upper airway surgery and/or noninvasive ventilation.nnCONCLUSION: Our findings highlight the importance of respiratory polygraphy in the management of patients with CM-ΙΙ.
