Case report. ⋯ The authors think that this is an effective method for reduction of these severe fractures.

Retrospective cohort study. ⋯ The FRS predicts the risk of complications after spine fusion surgery on the basis of patient and surgery characteristics. It also predicts the risk of intensive care unit admission and correlates with operative time, blood loss, and postoperative length of stay. By balancing the FRS procedure score to the individual FRS patient score, the surgeon can quantify and control perioperative risk.

Single-center retrospective study. ⋯ Extremely wide and asymmetric decompression concomitant with pre-existing C4-C5 foraminal stenosis may cause postoperative C5 palsy. Our findings should be valuable for surgeons considering anterior cervical decompression and fusion that includes the C4-C5 level. Surgeons should consider restriction of the decompression width to less than 15 mm and avoiding asymmetric decompression to reduce the incidence of C5 palsy.

Case report. ⋯ Accessory C1-C2 joints are possibly a result of genetic aberration giving rise to abnormality in segmentation of C1 sclerotome. These joints are dysmorphic and partially formed as evidenced by the absence of synovial membrane and capsule. The function of such joints remains questionable.

In vivo experimental porcine study. ⋯ Discography induced pressure increase in adjacent discs in a degenerate disc model, something not reported earlier. If present, also in human spine pressure transmission, may be a potential cause for false positive discography responses.
