Comparative Study
Cervical disc replacement-porous coated motion prosthesis: a comparative biomechanical analysis showing the key role of the posterior longitudinal ligament.
Benchtop cadaveric biomechanical comparative testing and caprine animal model in vivo implantation. ⋯ There are two basic types of total knee replacements, posterior cruciate ligament-preserving and posterior cruciate ligament-sacrificing designs. In the cervical spine, an analogous situation exists biomechanically depending on whether the posterior longitudinal ligament needs to be removed in its entirety as part of the spinal cord decompression part of the procedure--it may be helpful to conceptually differentiate between posterior longitudinal ligament-preserving and posterior longitudinal ligament-sacrificing total cervical disc replacements.

Experimental scoliosis was created in an immature goat model. ⋯ This study establishes an experimental model for scoliosis that creates progressive, structural, idiopathic-type, lordoscoliotic curves convex to the right in the thoracic spine of the immature goat with high statistical significance (P < 0.001). In addition, this method of experimental scoliosis creation avoids violation of the spinal elements throughout the maximal portion of the curve providing an ideal opportunity subsequent study of the deformity.

Comparative Study
Familial disability patterns in individuals with chronic work-related spine injury/illness.
A case control study of familial disability patterns and other potential risk factors identified in a group of individuals with work-related spine injury/illness. ⋯ These data suggest that the presence of a primary family member or spouse with a work-related spine disability may be a risk factor for the development of disability in individuals sustaining a work-related spine injury.

Review Meta Analysis
Physical conditioning programs for workers with back and neck pain: a cochrane systematic review.
To determine the effect on time lost from work of physical conditioning programs for workers with back and neck pain. DATA SOURCES Randomized trials were located by searching MEDLINE, EMBASE, CINAHL, PsycINFO, the Cochrane Controlled Trial Register, and PEDro. ⋯ Physical conditioning programs that incorporate a cognitive-behavioral approach reduce the number of sick days for workers with chronic back pain when compared to usual care.

Randomized Controlled Trial Comparative Study Clinical Trial
A randomized trial of combined manipulation, stabilizing exercises, and physician consultation compared to physician consultation alone for chronic low back pain.
A prospective randomized controlled trial. ⋯ The manipulative treatment with stabilizing exercises was more effective in reducing pain intensity and disability than the physician consultation alone. The present study showed that short, specific treatment programs with proper patient information may alter the course of chronic low back pain.
