Radiographic Adjacent Segment Degeneration at Five Years After L4/5 Posterior Lumbar Interbody Fusion With Pedicle Screw Instrumentation: Evaluation by Computed Tomography and Annual Screening With Magnetic Resonance Imaging.
Retrospective clinical study. ⋯ R-ASD was detected more frequently by CT and MRI than radiography. Preoperative facet joint degeneration and morphology were not always related to progressive disc degeneration or spinal stenosis. Annual MRI suggested that accelerated degeneration was due to lumbar spine fusion, rather than aging degeneration. Decompression with preservation of posterior connective components is recommended to prevent R-ASD.

Precise Bending Rod Technique a Novel Method for Precise Correction of Ankylosing Spondylitis Kyphosis.
Report of a new technique. ⋯ Precise rod bending technique is a simple, effective method for exact correction of kyphosis caused by ankylosing spondylitis. The surgical result was corresponded with the preoperative planning.

Effect of An Annular Closure Device (Barricaid) on Same Level Recurrent Disc Herniation and Disc Height Loss After Primary Lumbar Discectomy: Two-Year Results of a Multi-Center Prospective Cohort Study.
Prospective cohort study. ⋯ Implantation of a novel annular repair device was associated with greater maintenance of disc height and improved one-year leg pain, back pain, and low-back disability. Recurrent disc herniation did not occur in any patients after annular repair. Closure of annular defect after lumbar discectomy may help preserve physiologic disc function and prevent long-term disc height loss and associated back and leg pain.

Clinical TrialAnatomic relationship between superior mesenteric artery and aorta before and after surgical correction of thoracolumbar kyphosis.
A computed tomographic study. ⋯ The correlations of the surgical correction of kyphosis and the decreased aortomesenteric angle and distance in AS patients were quantitatively confirmed by our study. Spine surgeons should be aware of the potential risk for the development of superior mesenteric artery syndrome after kyphosis correction in AS patients.

Complications of correction for focal kyphosis after posterior osteotomy and the corresponding management.
A clinical retrospective study. ⋯ During the posterior osteotomy and correction of focal kyphosis, the risk of surgery increases along with the more severe deformity and the more complicated surgical procedure. However, most complications do not significantly affect the outcome if treated appropriately.
