Prospective cross-sectional measurement study. ⋯ Even though ceiling effects (>20%) were not common, scores clustered near the top of the SQLI scale. The SQLI score distribution may impair the questionnaire's sensitivity to change and discriminative ability, particularly in younger subjects with lesser low or moderate curve severity, under observation or after surgery. The clinical utility of some SQLI items within each domain may be limited by high ceiling effects.

Anecdotal reports and limited data suggest that the use of spinal injections is increasing, despite equivocal evidence about efficacy. ⋯ Lumbosacral injections increased dramatically in the Medicare population from 1994 to 2001. Less than half were performed for sciatica or radiculopathy, where the greatest evidence of benefit is available. These findings suggest a lack of consensus regarding the indications for ESIs and are cause for concern given the large expenditures for these procedures.

A retrospective review. ⋯ Percutaneous vertebroplasty and kyphoplasty have been reported to be safe options for the treatment of painful osteoporotic vertebral fractures. Although complications are infrequent, there remains the potential for catastrophic neurologic injury. Physicians performing these procedures need to be aware of these potential complications and be prepared to respond in an emergent manner (surgically) if a need arises.

A case report. ⋯ This case confirms the existence and clinical relevance of the fourth column of the thoracic spine and its role in providing added spinal stability in the patient with ankylosing spondylitis. As such, it is still possible to achieve a favorable clinical outcome in a select subpopulation of patients with ankylosing spondylitis that sustain three-column flexion-distraction injuries who are neurologically intact and are not candidates for surgical stabilization.

Prospective cohort follow-up study. ⋯ A longer duration of the current episode is the worst detected prognostic factor for response to NRT, but prognostic models are inaccurate for predicting the clinical outcome of a given patient. In order to improve the success rate of this technology, these results only support earlier referral for patients complying with current indication criteria.
