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.

A prospective clinical study. ⋯ The EM can develop into remarkable structures with spondylosis and aging in patients with cervical spondylotic myelopathy, affecting surgical outcomes as well as successful decompression procedures. A sound understanding of the histomorphological features of the EM is required to obtain satisfactory surgical outcomes in the limited field afforded by minimally invasive surgery.

A population-based, prospective cohort study. ⋯ Nearly 20% of the injured workers with LBP receive early MRI, a rate similar to that reported elsewhere. Early MRI may lead to greater subsequent interventions, potentially poorer outcomes, and increased health care expenditures. On the basis of the characteristics of patients with uncomplicated occupational LBP, providers may be able to provide tailored care, and providers and policy makers may better understand the utilization of imaging and adherence to clinical guidelines.

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.
