A retrospective radiographic study was carried out to analyze the effect of lumbar disc herniation on the kinetic motion of adjacent segments. ⋯ Although disc height, translational motion, and angular variation are significantly affected at the level of a disc herniation, no significant changes are apparent in adjacent segments. Our results indicate that herniated discs have no effect on range of motion at adjacent levels regardless of the degree of disc degeneration or the size of disc herniation, suggesting that the natural progression of disc degeneration and adjacent segment disease may be separate, unrelated processes within the lumbar spine.

The Oswestry Spinal Risk Index (OSRI) was recently reported as an adjunct in the management of metastatic spinal disease. Based on the tumour type and a general condition score, survivorship is predicted. We aimed to externally validate this new score. ⋯ We found that the OSRI is a simple to use scoring system. We found a strong correlation in our results with the predicted survivorship based on the OSRI. The OSRI can be used as a useful adjunct in the management of patient with metastatic disease of the spine.

To describe the effect of the C1 bursting fracture on the location of the internal carotid artery (ICA) around the atlas. ⋯ Lateral displacement of the bony structure of C1 bursting fracture changes the relative location of the ICA medially, which increase the injury risk during the bicortical C1 screw insertion. These data suggest that CT angiography or enhanced CT scans can give critical information to choose the ideal fixation technique and the proper trajectory of the screws for C1 bursting fracture.

Resection of calcified thoracic disc herniations carries significant risks of neurological worsening, particularly in case of concomitant central location. Transthoracic approaches are a first-choice option to avoid spinal cord manipulation but entail drawbacks such as postoperative pain and the risk of bronchopulmonary complications. The purpose of this report is to describe a novel approach to resect calcified herniations, even centrally located, from a posterior perspective. ⋯ The endoscope-assisted posterior approach afforded safe and complete resection of calcified discs. The technique is particularly useful for central disc herniations, where transthoracic approaches are normally deemed mandatory.

This report describes the characteristics of conservative cases with a coronally oriented vertical fracture of the posterior region of the C2 vertebral body. ⋯ The patients with a coronally oriented vertical fracture of the posterior region of the C2 vertebral body consisted were all elderly males in our study. Six of the eight patients demonstrated associated cervical spinal fractures; however, all patients acquired solid bony union, including fusion of the associated cervical spinal fractures. We suggest that a Philadelphia collar may be sufficient for conservatively treating coronally oriented vertical C2 body fractures, including associated cervical spinal fractures.
