Comparative Study
A comparison of fear-avoidance beliefs in patients with lumbar spine pain and cervical spine pain.
A prospective consecutive cohort study of patients with cervical spine pain and patients with lumbar spine pain referred to an academic medical center. ⋯ The associations among fear-avoidance beliefs, pain intensity, and disability differed between patients with cervical spine pain and patients with lumbar spine pain. Fear-avoidance beliefs were significantly different in subgroups of patients.

An in vitro biomechanical investigation on human cadaveric specimens was conducted before and after nucleotomy. Endplate and vertebral body deformation patterns were measured under compression and shear loading, in addition to kinematics and disc pressure. ⋯ Nucleotomy resulted in decreased disc pressure, decreased endplate deformation, and modified loading patterns onto the inferior vertebra in compression loading. However, nucleotomy did not appreciably affect the behavior of the disc in shear loading.

Case report of severe scoliosis and associated pelvic obliquity in a 14-year-old patient with cerebral palsy. ⋯ It is concluded that scoliosis with associated severe pelvic obliquity deformities can be treated with anterior and posterior spinal fusion and instrumentation with intraoperative halo-femoral traction in the properly selected and prepared patient with cerebral palsy.

A lumbar radiculopathy model investigated pain behavioral responses after nerve root reinjury. ⋯ The bilateral responses support central modulation of radicular pain after nerve root injury. An exaggerated and more prolonged response bilaterally after reinjury suggests central sensitization after initial injury. Neuroinflammatory activation in the spinal cord further supports the hypothesis that central neuroinflammation plays an important role in chronic radicular pain.

Systematic review of prognostic studies of acute whiplash. ⋯ Scant knowledge about the prognosis of whiplash has been gained since the release of the Quebec Task Force report. However, it is becoming obvious that the insurance and compensation systems have a large impact on recovery from acute whiplash injuries. The conceptual framework used in this study demonstrates that large cohort studies investigating a wide range of prognostic factors are necessary to improve the understanding of this problem.
