Comparative Study Clinical Trial
Comparison of 3 fusion techniques in the treatment of the degenerative cervical spine disease. Is stand-alone autograft really the "gold standard?": prospective study with 2-year follow-up.
A prospective study. ⋯ Significantly worse radiological and clinical results after 2 years of follow-up were achieved using stand-alone autograft technique in comparison with autograft supported by anterior plating similarly as in comparison with cage implant and anterior plating. Using artificial fusion substrate together with plate and cage can offer the same clinical and radiological results such as iliac autograft and plating. Anterior plating seems to be an important factor influencing the postoperative cervical spine alignment and also the clinical outcome.

Case Reports
Paraplegia in pregnancy: a case of spinal vascular malformation with Klippel-Trenaunay syndrome.
A case report. ⋯ Pregnancy complicated by paraplegia is thought to be secondary to venous engorgement and to the resulting spinal cord ischemia in this case. Her neurological symptoms and signs gradually improved over the few days after cesarean delivery.

Comparative Study
Validity and reliability of the metric measurements in the assessment of lumbar spine motion in patients with ankylosing spondylitis.
A prospective, controlled clinical study performed in a tertiary care center. ⋯ Despite excellent intrarater reliabilities for OST, MSI, and MMST, only a weak correlation could be established between OST, MSI, and MMST and radiographical analysis. MMST was found not to reflect lumbar spine angular motions. Although MSI reflected spinal mobility better than OST, both seemed to reflect lumbar spine angular motion poorly.

Comparative Study
Can a novel rectangular footplate provide higher resistance to subsidence than circular footplates? An ex vivo biomechanical study.
Ex vivo biomechanical evaluation using cadaveric vertebral bodies. ⋯ A rectangular footplate design is more resistant to subsidence than a circular footplate design in an ex vivo biomechanical model. The new design had higher load to failure even in the presence of a central defect. These findings suggest that rectangular footplates may provide better subsidence resistance when used to reconstruct defects after thoracolumbar corpectomy.

Serial, cross-sectional, nationally representative surveys of noninstitutionalized US adults. ⋯ Although this study did not explore the relative effectiveness of different ambulatory services, recent increasing costs associated with providing medical care for back and neck conditions (particularly subspecialty care) are contributing to the growing economic burden of managing these conditions.
