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 retrospective chart review of all patients who underwent posterior cervical fusion during a 1-year time period. ⋯ rhBMP can safely be used in patients undergoing posterior cervical fusion, as it does not produce complications at the rate previously seen with its use in the anterior cervical spine.

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.

Literature review. ⋯ In light of the difficulty in measuring BPD recurrence, transparent definitions and a clear understanding of the implications of using particular indicators is required. Future research should focus: on examining the capture BPD recurrence by various research instruments, improving understanding of the relationship between indicators, and gaining insight into how individuals experiencing BPD view recurrence.
