A randomized comparison of conventional and image-guided technology techniques for pedicle screw placement was performed. ⋯ Accuracy of pedicle screw placement in the thoracolumbosacral spine is improved with the use of image-guided methods, particularly guidance by computed tomography. This is especially relevant clinically when the anatomy is obscured or altered as a result of inflammatory spondyloarthropathy (e.g., ankylosing spondylitis in which spontaneous fusions obscure surgical landmarks for pedicle access), or when used postsurgically in the setting of a posterolateral fusion.

A literature review was conducted. ⋯ The ultimate efficacy of spinal cord stimulation remains to be determined, primarily because of limitations associated with the published literature. However, on the basis of the current evidence, it may represent a valuable treatment option, particularly for patients with chronic pain of predominantly neuropathic origin and topographical distribution involving the extremities. The potential treatment of other pain topographies and etiologies by spinal cord stimulation continues to be studied.

The literature and current research related to spinal pain mechanisms were reviewed, as well as animal models related to its study. ⋯ Areas of continued research are highlighted that may help guide the management of painful spine symptoms and syndromes.

Randomized Controlled Trial Comparative Study Clinical Trial
The effects of side-posture positioning and spinal adjusting on the lumbar Z joints: a randomized controlled trial with sixty-four subjects.
A blinded, randomized controlled trial was conducted. ⋯ Spinal adjusting produced increased separation (gapping) of the Z joints. Side-posture positioning also produced gapping, but less than that seen with lumbar side-posture adjusting. This study helps to increase understanding about the mechanism of action for spinal manipulation.

The cost of chronic benign spinal pain is large and growing. The costs of interventional treatment for spinal pain were at a minimum of $13 billion (U. S. dollars) in 1990, and the costs are growing at least 7% per year. ⋯ Cost-minimization versus cost-effectiveness approaches are described. Spinal cord stimulation and intraspinal drug infusion systems are alternatives that can be justified on a cost basis. Cost minimization analysis suggests that epidural injections under fluoroscopy may not be justified by the current literature.
