Predictors of marked improvement versus failure to improve following surgery for adult scoliosis have not been identified. Our objective was to identify factors that distinguish between patients with the best and worst outcomes following surgery for adult scoliosis. ⋯ Not all patients achieve favorable outcomes following surgery for adult scoliosis. Baseline and peri-operative factors distinguishing between patients with the best and worst outcomes were predominantly patient factors, including BMI, depression/anxiety, smoking, and pain severity; not comorbidities, severity of deformity, operative parameters, or complications.

To investigate whether rs11190870 near LBX1 correlates with the susceptibility or curve progression of adolescent idiopathic scoliosis (AIS) in a Han Chinese population. ⋯ The SNP rs11190870 near LBX1 is associated with both susceptibility and curve progression of AIS.

This study aims to investigate the use of biplanar radiography for assessing congenital scoliosis due to hemivertebra in 3D. ⋯ Biplanar radiography can be considered an interesting tool for clinical follow-up of congenital scoliosis as it overcomes some limitations of the analyses based on CT or anteroposterior X-ray: head to feet acquisition, low radiation dose and provides a set of automatically computed postural and morphological parameters in 3D.

The rotation or translation of vertebrae in adolescent idiopathic scoliosis (AIS) patients could cause the relative migrations of surrounding vital structures and lead to smaller safe zones for pedicle screw insertion. This study aimed to determine the changed relative position of trachea to spine in the proximal thoracic curve (T1-T4) and to analyze the potential risks of tracheal injuries from pedicle screw insertions in AIS patients. ⋯ This CT-based study demonstrates that the FPT curve has a smaller safe zone with respect to tracheal injury during screw insertion. Spine surgeons should choose the appropriate screw length to avoid anterior wall perforation.

Until now there have been many reports on hemivertebra resection. But there were no large series on the posterior hemivertebra resection with bisegmental fusion. This is a retrospective study to evaluate the surgical outcomes of posterior hemivertebra resection only with bisegmental fusion for congenital scoliosis caused by fully segmented non-incarcerated hemivertebra. ⋯ Posterior hemivertebra resection with bisegmental fusion allows for early intervention in very young children. Excellent correction can be obtained while the growth potential of the unaffected spine could be preserved well. However, it is not indicated for the hemivertebra between L5 and S1. The most common complication of this procedure is implant failure. Furthermore, in the very young children we noted that although solid fusion could be observed in the fusion level, implants migration may still happen during the time of adolescence, when the height of the body developed rapidly. So a close follow-up is necessary.
