The purpose of this study is to determine if there are any demographic and reporting differences between patients who respond and those who refuse to respond to postal questionnaires from the Danish national spine database, DaneSpine. ⋯ Missing data from 12 % of patients do not seem to bias conclusions that can be drawn from the DaneSpine database at the Center for Spine Surgery and Research at Lillebaelt Hospital.

The state of adjacent level discs and its impact on surgical outcomes following single-level lumbar discectomy have not been previously investigated. The purpose of the present study was to determine if a significant relationship exists between the degree of preoperative adjacent level disc degeneration and post-operative clinical outcomes following lumbar discectomy. ⋯ The degree of preoperative adjacent level degeneration does not significantly affect functional or pain relief outcomes following lumbar discectomy up to 1 year after surgery.

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.

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.

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.
