To investigate the relationship between spinal cord anatomy and the risk of curve progression in mild to moderate adolescent idiopathic scoliosis (AIS). ⋯ We found significant displacement of the medulla towards the concavity of the curve in progressive AIS. This finding supports the theory of a neuro-osseous growth mismatch as a part of the etiopathophysiology of AIS and may play a predictive role in prognosis of milder cases of AIS.

Although many studies have reported clinical outcomes of spinal ependymoma (SE) patients after gross total resection (GTR), the data about the patient reported outcomes of the quality of life (PRO-QOL) was limited. ⋯ From the perspective of PRO-QOL, neurological rehabilitation should be continued for at least 6-12 months after GTR to the SE patients. For the preoperative patients with severe neurological damage, long-level intraspinal tumor and low VAS score, more cautious surgical considerations, more perioperative attention and earlier neurological intervention are necessary.

Residual back pain (RBP) is one of the complications following percutaneous vertebroplasty (PVP) in older people with osteoporotic vertebral compression fractures (OVCFs). The vertebral bone quality (VBQ) score obtained from magnetic resonance imaging (MRI) can be used to evaluate bone quality. The objective of this study aimed to explore the potential relationship between the VBQ score and RBP after PVP. ⋯ The preoperative high VBQ score was an independent risk factor associated with RBP after PVP. Moreover, other risk factors included low BMD, lumbodorsal fascia contusion, and cement distribution. The MRI-VBQ score may serve as a useful tool for assisting in evaluating patients at risk of RBP following PVP.

To evaluate the modified vertebral bone quality (VBQ) method on the magnetic resonance imaging (MRI) T1-weighted (T1w), T2-weighted (T2w), and fat suppression (FS) series in evaluating bone mineral density (BMD) for patients with degenerative lumbar disease. ⋯ Compared to the traditional VBQ score, T2 VBQCSF is a more promising tool for distinguishing poor bone quality in patients with degenerative lumbar disease. A T2 VBQCSF score > 0.607 can identify patients who require additional diagnostic evaluation.

Vertebral Hounsfield unit values on computed tomography scan (CT values) have been found to be correlated with bone density measured using dual-energy X-ray absorptiometry. We hypothesized that low preoperative CT values are risk factors for early loss of correction after percutaneous posterior spinal fixation (PPSF). This study aimed to evaluate the usefulness of measuring preoperative CT values. ⋯ CT values can predict progressive loss of correction after PPSF.
