Retrospective study of 55 consecutive patients with spinal metastases secondary to breast cancer who underwent surgery. ⋯ The modified Tokuhashi score assists in decision making based on reliable estimators of life expectancy in patients with spinal metastases secondary to breast cancer.
-
A retrospective cohort with cross- sectional follow-up. ⋯ Motor recovery does not occur below the zone of injury for patients with complete SCI. Varying degrees of local recovery can be expected in tetraplegic individuals.
-
A biomechanical study investigating the intradiscal mechanics of human lumbar intervertebral discs (IVDs). ⋯ Increased nucleus pulposus migration in degenerated IVDs may result in increased shifting of the IVD pivot point during bending movements as well as intradiscal anular strains, particularly in the posterolateral anulus. This phenomenon may explain the segmental instability observed in degenerated segments as well as the associated anular tears present in the posterolateral region before IVD failure.
-
Case control study. ⋯ PMMA cement might not be as bioinert as we considered. Therefore, the long-term safety of vertebroplasty should be further evaluated.
-
Retrospective clinical and intraoperative navigational data review. ⋯ Image-guided thoracoscopic spinal surgery can provide 3-dimensional orientation to a 2-dimensional imaging procedure that ultimately improves accuracy, efficiency, and safety. Future developments in combining guidance technology with standard surgical procedures will likely continue.
