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.

Spinal epidural arachnoid cysts (SEACs) are rare, non-neoplastic pathologies that can cause compressive myelopathy. Preoperative identification of the exact fistula location is crucial for minimally invasive management. ⋯ The "double-needle puncture myelography" technique allows for the swift acquisition of precise anteroposterior and lateral projection dynamic X-ray images during the procedure. As a valuable preoperative diagnostic tool, it accurately pinpoints the location of the fistula, thereby minimizing surgical trauma and preserving spinal stability.

Adjacent vertebral fracture (AVF) is a frequent complication following percutaneous vertebral augmentation (PVA). While radiomics is widely utilized in the field of spinal medicine, its application for assessing the risk of AVF in post-PVA patients remains limited. ⋯ Radiomics and machine learning modeling using postoperative CT images demonstrate noteworthy capability in assessing the risk of AVF following PVA.

Although idiopathic scoliosis is a common three-dimensional deformity, there is a lack of studies evaluating the associations between the aortic-vertebral distance (AVD) and spinal deformities in all planes. The study therefore aimed to evaluate how the coronal and sagittal curvature, vertebral rotation and aortic-vertebral angle (AVA) affect the AVD in idiopathic scoliosis. ⋯ The shortest distance from the aortic wall to the vertebral body wall is primarily influenced by vertebral rotation and the AVA within the thoracic curve. Thus, these factors need to be taken into consideration when planning pedicle screw placement especially in freehand techniques.

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.
