Cross-sectional analysis. ⋯ A small but significant number of injured workers do not seek care for their back pain. Medical physicians treat all but a small fraction of the workers who receive care. The decision to seek care and the choice of providers is associated with injury severity, occupation, and employer actions.

Comparative Study
Non-fusion surgery for degenerative spondylolisthesis using artificial ligament stabilization: surgical indication and clinical results.
A retrospective study. ⋯ Artificial ligament stabilization did not improve the vertebral slip but maintained lordosis and preserved segmental motion in 80% of patients. This procedure is an effective alternative to spinal arthrodesis in the treatment of symptomatic degenerative spondylolisthesis (Grade I) with minimal disc space narrowing and coronal facet tropism.

Case Reports
Atlanto-occipital dislocation with traumatic pseudomeningocele formation and post-traumatic syringomyelia.
A case report of traumatic atlanto-occipital dislocation complicated by the development of anterior and posterolateral pseudomeningoceles and the late development of syringohydromyelia is presented. ⋯ Atlanto-occipital dislocation is rarely survivable, and delayed diagnosis can negatively affect long-term clinical outcome. This case illustrates how, despite early signs of improvement, post-traumatic syringomyelia may occur months or even years after spinal trauma and should always be considered in patients who experience late neurologic deterioration after atlanto-occipital dislocation.
