Case Reports
Partial lumbosacral transitional vertebra resection for contralateral facetogenic pain.
Case report of surgically treated mechanical low back pain from the facet joint contralateral to a unilateral anomalous lumbosacral articulation (Bertolotti's syndrome). ⋯ Clinicians should consider the possibility that mechanical low back pain may occur from a facet contralateral to a unilateral anomalous lumbosacral articulation, even in a young patient. Although reports of surgical treatment of Bertolotti's syndrome are infrequent, resection of the anomalous articulation provided excellent results in this patient, presumably because of reduced stresses on the symptomatic facet.

With a retrograde neurotracing method with Fluoro-Gold (FG; Fluorochrome, Denver, CO), the level of dorsal root ganglions (DRGs) innervating the C1-C2, C3-C4, and C5-C6 facet joints and their pathways were investigated in rats. ⋯ Sensory nerve fibers of the cervical facet joint were derived from the C1-T3 DRGs. Some sensory nerves from the cervical facet joint entered the paravertebral sympathetic trunks and reached the DRGs at multisegmental levels. The present findings regarding the multisegmental innervation to the facet joint may be of importance in the treatment of facet joint syndrome.

Randomized Controlled Trial Clinical Trial
Helping patients decide about back surgery: a randomized trial of an interactive video program.
A randomized trial of 100 patients with low back pain who were potential surgical candidates. ⋯ Both the booklet alone and the combination of videodisc and booklet improved knowledge. The combination produced greater knowledge gains than the booklet alone for the subgroup with the least knowledge at baseline. Patients preferred the combination and had a slightly lower preference for surgery if they had viewed the video presentation. For some patients, the video may enhance involvement in clinical decisions.

Repeated measures for intratester reliability were performed. ⋯ Inclinometer and lumbar rotameter measurements with the use of a pelvic restraint device are reliable for measuring lumbar spine range of motion. Use of the inclinometer technique to record lumbar lordosis also is a reliable measure.

A longitudinal study using patient questionnaires was performed. ⋯ The two specific instruments are capable of greater levels of discrimination between groups of patients, and are more responsive over time than the generic EuroQol. The Aberdeen instrument performed most satisfactorily in relation to these criteria, but the Roland instrument was more sensitive to differences between the two groups in the clinical trial. The measurement properties of these two instruments reflect their origin: The Aberdeen instrument is based on clinical questions, whereas the Roland instrument is based on the generic Sickness Impact Profile. Instrument content should be carefullyconsidered when selecting instruments for applications, including clinical trials.
