Comparative Study
Comparison of short- and long-term outcomes for aggressive spine rehabilitation delivered two versus three times per week.
Rehabilitation services using intensive exercise for the treatment of chronic spinal pain have traditionally been scheduled at a frequency of three times per week. ⋯ Similar outcomes were obtained from aggressive spine rehabilitation occurring two versus three times per week in patients presenting with moderate levels of chronic spinal pain. Reduction in physical therapy services and therefore cost did not adversely affect clinical outcomes in the treatment of this patient population.

Comparative Study
Comparing outcomes of anterior cervical discectomy and fusion in workman's versus non-workman's compensation population.
Anterior cervical discectomy and fusion (ACDF) is an accepted surgical procedure to treat degenerative conditions, including disc herniations and spinal stenosis. The literature on lumbar spine surgery reports that patients with a workman's compensation claim have less successful clinical results. Regarding the cervical spine, however, different conclusions have been drawn. ⋯ Workman's compensation claims did not adversely affect the functional outcome of ACDF. It should be noted that a significant increase in pseudarthroses was noted with the smoking population. Patient selection is a critical factor in determining functional outcome, with 83% good to excellent results if the pathology, clinical presentation and radiographic findings correlate

Comparative Study
Measurements of lumbopelvic lordosis using the pelvic radius technique as it correlates with sagittal spinal balance and sacral translation.
Maintenance of normal lumbar lordosis is important in the treatment of spinal disorders. Many attempts have been made to quantify normal sagittal spinal alignment and lordosis using a C7 plumb line and segmental angulations of the spinal vertebrae. Little attention has been given to pelvic compensation as it correlates to lumbar lordosis and overall sagittal spinal alignment. Better methods of measuring lordosis, which correlate with sagittal spinal balance and pelvic compensation, are needed in treating patients with spinal disorders. ⋯ Sacral translation, the C7 plumb line and lumbopelvic lordosis are useful measures for sagittal spinal balance. Lumbopelvic lordosis and sacral translation can be correlated to the sagittal spinal balance. Understanding these measurements and the range of lumbopelvic compensation can be extremely helpful in treating patients with spinal pathology and in avoidance of flatback deformity. Application of these measures would be especially helpful in the treatment of patients with spinal fusion, degenerative spondylosis, disc disease, fractures, and in the prevention of sagittal malalignment.

Comparative Study
Anatomic consideration for standard and modified techniques of cervical lateral mass screw placement.
Posterior screw placement techniques have been previously described. Each technique differs with respect to starting point, lateral angulation and sagittal orientation. ⋯ The present study indicates that there are significant differences of potential neurovascular injury, which is dependent on the technique used for screw entry, the level instrumented and the angle of screw trajectory in the parasagittal plane.
