Prospective case series. ⋯ SIJ blocks with triamcinolone acetonide are beneficial for some patients with SIJ pain without spondyloarthropathy. The SIJ blocks showed a long-lasting efficacy in two-thirds of the patients; however, the duration of its efficacy was shorter in patients with a history of lumbar/lumbosacral fusion. These findings suggest the need for further studies.

Retrospective cohort. ⋯ In the elderly, adjusted rates of cervical spine fusions rose 206% from 1992 to 2005. Marked geographic variation was noted. Future studies should evaluate the efficacy and complications associated with these procedures in the elderly, and better define surgical indications and patient outcome.

A systematic review of randomized controlled trials. ⋯ There is strong evidence that insoles are not effective for the prevention of back pain. The current evidence on insoles as treatment for low back pain does not allow any conclusions.

Biomechanical evaluation of occipitocervical instrumentation techniques. ⋯ Occipital screw placement off-midline improves screw loads under lateral bending forces on occipitocervical constructs, though loads for FE and ROT are unchanged. As screws pullout, the loads may be redistributed, resulting in increased screw pullout forces above. Despite the improvement in screw loads for laterally based plates during lateral bending, overall ROM across the occipitocervical junction is unchanged.

A cross-sectional population study of magnetic resonance imaging (MRI) changes. OBJECTIVE.: To examine the pattern and prevalence of lumbar spine MRI changes within a southern Chinese population and their relationship with back pain. ⋯ LDD is common, and its incidence increases with age. In a population setting, there is a significant association of LDD on MRI with back pain.
