Severe rigid spine deformity with sharp curve can be effectively corrected by posterior vertebral column resection (PVCR). Meanwhile, high risk of this procedure also has been recognized generally. The aim of this study is to review and evaluate the role of preoperative skull-femoral traction prior to PVCR for extremely severe rigid spinal deformity with sharp angular curve >150°. ⋯ Preoperative skull-femoral traction effectively mitigates the neurological risks of PVCR for extremely severe rigid spinal deformity with sharp curve. During traction, scoliosis can be improved more significantly and easily than kyphosis.

We estimated the annual changes in radiographic indices of the spine in cerebral palsy (CP) patients and analyzed the factors that influence its progression rate. ⋯ The scoliosis Cobb angle, thoracic kyphosis angle, and apical vertebral translation in the GMFCS level IV-V CP patients progressed with age. These findings can predict radiographic progression of scoliosis in CP patients.

Intraoperative ultrasound (IUS) has been described in numerous papers as an effective tool for spinal tumor resection, degenerative lesions and Chiari malformation surgery, but has not been routinely adopted by spine surgeons. We herein describe our experience with routine IUS application. ⋯ IUS is safe and easy to use after a short learning curve. When used in indicated cases, it can replace cumbersome fluoroscopy, reduce the incision dimension and laminectomy levels, and demonstrate the extent of decompression. Incorporating IUS in spinal surgery education programs is warranted.

Iatrogenic injuries to paraspinal muscles during the posterior lumbar surgery (PLS) cause a reduction in their cross-sectional areas (CSAs) and contractile densities over time post-surgery. This study aims to quantify such alterations. ⋯ The total CSA of ES at lower lumbar levels shows substantial noncontractile contents in both healthy and patient populations. Biomechanical models of the spine should hence account for the noncontractile contents using only the effective contractile muscle CSAs. Postoperative variations in CSAs of paraspinal muscles may have profound effects on patterns of muscle activities, spinal loading, and stability.

The practice of giving certain authors equal credit in scientific publications has become increasingly common in some medical specialties. However, whether this trend also exists in major spine journals remains unclear. This study aimed to investigate the prevalence and characteristics of the practice of giving authors equal credit in major spine journals. ⋯ The practice of ECA in original research articles is increasingly common in major spine journals. A guideline for authors regarding when and how to designate equal credit is warranted in the future.
