Many degenerative phenomena frequently result into kyphotic lumbar and thoracic deformities or cause their progression combined with deformities on the frontal plane of the spine. In these patients, the progression of the sagittal imbalance may lead to a series of disabling functional and painful consequences. The analysis of the spinopelvic parameters biases the choice of the correction surgical strategy aimed at restoring a good tri-dimensional and sagittal balance of the spine. ⋯ In our experience, patients with sagittal imbalance and short fusion areas show a higher risk of correction loss; the arthrodesis area must include the thoracolumbar junction, and it is often necessary to include the whole thoracic spine in the arthrodesis area. This is to avoid any loss of correction, implants mobilization, and proximal hyperkyphosis.

To evaluate fracture healing, functional outcomes, complications, and mortality associated with rigid cervical collars. ⋯ Odontoid nonunion and instability are high in geriatric patients treated with a rigid cervical collar. Fracture healing and stability did not correlate with improved outcomes. Outcomes did not differ significantly from age-matched cohorts.

The purpose of this study was to assess the efficacy and accuracy of posterior screw fixation for unstable Hangman's fracture using intraoperative 3D fluoroscopy-based navigation. ⋯ This case series demonstrates that intraoperative 3D fluoroscopy-based navigation is a safe, accurate, and effective tool for screw placement in patients with unstable Hangman's fracture.

Percutaneous vertebroplasty (PVP) and percutaneous kyphoplasty (PKP) are effective procedures to alleviate pain caused by osteoporotic vertebral compression fractures (VCFs). New vertebral compression fracture (NVCF) has been noted as a potential late sequela of the procedures. The incidence of NVCFs and affecting risk factors were investigated. ⋯ The most important risk factors affecting NVCFs were osteoporosis and intervertebral discal cement leakage.

To summarise our experience treating patients with spinal malignant peripheral nerve sheath tumours (MPNSTs). ⋯ Diagnosis of spinal MPNSTs should be made with reference to clinical, radiological, and pathological findings. Surgical resection is the best available option for treating spinal MPNST; however, postoperative prognosis is poor.
