-
Cross-sectional study. ⋯ Lower BMD is associated with a decreasing trend in both lumbar vertebral and disc volumes in elderly subjects but an increase in the Hm of the intervertebral discs.
-
A case report. ⋯ Delayed anterior spinal artery syndrome after aortic coarctation repair because of anterior spinal artery thrombosis can manifest even 6 months postoperatively. Careful analysis of pre- and postoperative cross-sectional imaging should provide the correct diagnosis. Spinal digital subtraction angiography is probably unnecessary and must be interpreted with caution.
-
Biomechanical cadaver investigation. ⋯ Lumbar FSUs with implanted TDR were found to be less stiff, but absorbed more energy during cyclic loading with an unconstrained pendulum system. Although the effects on clinical performance of motion-preserving devices are not fully known, these results provide further insight into the biomechanical behavior of these devices under approximated physiological loading conditions.
-
Analysis of a case series of 24 patients with Lenke 1C adolescent idiopathic scoliosis (AIS) receiving selective thoracoscopic anterior scoliosis correction. ⋯ Selective thoracoscopic anterior fusion allows spontaneous lumbar curve correction and achieves coronal balance of main thoracic and compensatory lumbar curves, good cosmesis, and patient satisfaction. Correction and balance are maintained 24 months after surgery.
-
A retrospective review of a prospectively collected database. ⋯ This study provides rates and causes of mortality associated with spine surgery for a broad range of diagnoses and includes assessments for adult and pediatric patients. These findings may prove valuable for patient counseling and efforts to improve the safety of patient care.
