Multicenter Study
Racial differences in the use of lumbar spine radiographs: results from the Veterans Health Study.
We analyzed data from the Veterans Health Study, a longitudinal study of male patients receiving VA ambulatory care. ⋯ There was greater use of lumbar spine radiographs by nonwhite patients compared with white patients. This remained true when patients were subcategorized by severity of LBP or SLR test. However, race had no influence when multiple clinical characteristics of the patients were controlled for simultaneously. This study demonstrates the importance of careful and comprehensive case-mix adjustment when assessing apparent differences in the use of medical services.

A prospective cohort study evaluating age as a factor in treatment outcomes for chronic disabling work-related spinal disorders undergoing tertiary rehabilitation. ⋯ The present study represents the first large-scale examination of the association between age and treatment outcomes for a work-related CDSD population. Age is significantly and linearly related to pretreatment duration of disability and frequency of pretreatment surgeries. After rehabilitation treatment there is a linear decrement in both work return and work retention, so that younger patients are far more likely to return and hold work after functional restoration. Older workers who go back to work are much more likely to return to the same employer and do the same job, or to become self-employed. Calculation of odds ratios revealed that patients >55 years are 5.68 times more likely to return to the same job and employer, relative to those <25 years; those >55 years were also approximately three times more likely than those <25 years to return to the same employer, compared with those <25 years. Younger workers are far more likely to take a different job and/or seek a new employer. Older patients are also somewhat more likely to seek a new health provider to deal with perceived residual pain/disability. This trend coincides with their higher post-treatment subjective disability levels, and their lower cumulative physical scores both prerehabilitation and postrehabilitation. However, age does not affect additional surgery rates, subsequent injuries, or delays in settling financial disputes.

Comparative Study Clinical Trial
Radiofrequency medial branch neurotomy in litigant and nonlitigant patients with cervical whiplash: a prospective study.
The efficacy of radiofrequency medial branch neurotomy to treat cervical zygapophysial joint pain from whiplash was compared prospectively in litigants and nonlitigants. ⋯ These results demonstrate that the potential for secondary gain in patients who have cervical facet arthropathy as a result of a whiplash injury does not influence response to treatment. These data contradict the common notion that litigation promotes malingering. This study also confirms the efficacy of radiofrequency medial branch neurotomy in the treatment of traumatic cervical facet arthropathy.

Comparative Study
Laminoplasty versus laminectomy and fusion for multilevel cervical myelopathy: an independent matched cohort analysis.
A matched cohort clinical and radiographic retrospective analysis of laminoplasty and laminectomy with fusion for the treatment of multilevel cervical myelopathy. ⋯ The marked difference in complications and functional improvement between these matched cohorts suggests that laminoplasty may be preferable to laminectomy with fusion as a posterior procedure for multilevel cervical myelopathy.

A case report of bilateral phrenic nerve palsy as a complication of anterior decompression and fusion for cervical ossification of the posterior longitudinal ligament (OPLL). ⋯ Bilateral phrenic nerve palsy occurred after anterior decompression and fusion for cervical OPLL. Bilateral phrenic nerve palsy should be kept in mind as a serious complication of spinal surgery. It should be considered when patients unexpectedly fail to wean from the ventilator after surgery.
