Intraoperative traction can improve deformity correction during posterior spinal fusion (PSF). This is commonly done with invasive distal femoral or pelvic pins, or traction boots. The novel technique of intraoperative skin traction (ISkinT) avoids risks associated with intraoperative skeletal traction (ISkelT) or hyperlordosis with extended hip position. We aimed to describe ISkinT and assess its safety and efficacy in PSF in non-ambulatory scoliosis. ⋯ In non-ambulatory neuromuscular pediatric scoliosis patients, ISkinT during PSF to the pelvis is a safe and effective technique for deformity correction. There were no associated complications and no difference of corrective capacity for ISkinT compared to ISkelT. ISkinT can be considered for T2-pelvis PSF for pediatric scoliosis.

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.

To study the effect of percutaneous kyphoplasty (PKP) combined with microwave ablation (MWA) on pain and clinical outcomes in patients with spinal metastases. ⋯ PKP combined with MWA elevates the height of the diseased vertebrae, alleviates the symptoms of pain and dysfunction, and promotes the quality of life and physical status in patients with spinal metastases.

To devise a mathematical model for estimating the intraoperative lowest instrumented vertebra (LIV) tilt angle using preoperative supine left side-bending (LSB) radiographs in adolescent idiopathic scoliosis (AIS) patients with Lenke type 1 and 2 (non-AR curves), and to review its clinical and radiological outcomes. ⋯ Achieving an intraoperative LIV tilt angle (β) greater than or equal to the preoperative α angle derived (β ≥ α) may help avoid the distal AO phenomenon.
