Prospective case series with historical controls (normative data). ⋯ CLBP patients, especially men, seem to have a reduced aerobic fitness level compared with the normative population. No explanatory factor for that loss could be identified.
-
A prospective follow-up study. ⋯ In addition to neurologic deficits, cervical spondylotic myelopathy also causes sexual dysfunction. Most of these patients had an abnormal psychogenic erection and normal reflexogenic erection. Along with neurologic recovery, most patients had improvement in sexual function after surgery.

Computerized tomographic study of human cadavers undergoing traction and flexion-extension bending. ⋯ The CTJ, as a transition region between the cervical and thoracic spines, has unique kinematic characteristics. This application of kinematic CT methods is useful for quantifying unreported normative ranges of motion for the CTJ, difficult by other conventional radiologic means.

This study determined bone mineral density (BMD) of cervical, thoracic, and lumbar vertebrae in healthy asymptomatic human subjects. ⋯ The present study failed to support the hypothesis that BMD of lumbar spine vertebrae is equivalent to its cranial counterparts. The lack of differences in BMD among the three lumbar vertebral bodies confirms the appropriateness of using L2, L3, or L4 in clinical or biomechanical situations. However, significant differences were found among different regions of the vertebral column, with the cervical spine demonstrating higher trabecular densities than the thoracic and lumbar spines. In addition, the present study found statistically significant variations in densities even among neck vertebrae.

An experimental study using cadaveric vertebrae. ⋯ The new cannula may improve vertebroplasty by significantly easing cement injection. It is cost effective and can be easily integrated into the existing procedure.
