Multicenter StudyOutcome predictors for sacroiliac joint (lateral branch) radiofrequency denervation.
Sacroiliac (SI) joint pain is a challenging condition characterized by limited treatment options. Recently, numerous studies have reported excellent intermediate-term outcomes after lateral-branch radiofrequency (RF) denervation, but these studies are characterized by wide variability in technique, selection criteria, and patient characteristics. The purpose of this study was to determine whether any demographic or clinical variables can be used to predict SI joint RF denervation outcome. ⋯ Whereas several factors were found to influence outcome, no single clinical variable reliably predicted treatment results. The use of more stringent selection criteria was not associated with better outcomes.

Lumbar disc prolapse, protrusion, or extrusion account for less than 5% of all low back problems, but are the most common causes of nerve root pain and surgical interventions. The primary rationale for any form of surgery for disc prolapse is to relieve nerve root irritation or compression due to herniated disc material. The primary modality of treatment continues to be either open or microdiscectomy, but several alternative techniques including nucleoplasty, automated percutaneous discectomy, and laser discectomy have been described. There is a paucity of evidence for all decompression techniques, specifically alternative techniques including nucleoplasty. ⋯ This systematic review illustrates Level II-3 evidence for mechanical lumbar percutaneous disc decompression with nucleoplasty in treatment of leg pain. However, there is no evidence available in managing axial low back pain.

Comparative Study
Patient-preference disability assessment for disabling chronic low back pain: a cross-sectional survey.
A cross sectional survey. OBJECTIVE.: To assess patient priorities in disability and restriction in participation with disabling chronic low back pain (CLBP) by use of the McMaster-Toronto Arthritis Patient Preference Disability Questionnaire (MACTAR) and to compare this questionnaire with other outcome measures widely used in this situation. ⋯ For assessing priorities in disability and participation restriction among patients with CLBP, the MACTAR has acceptable construct validity. The weak correlation between QUEBEC and MACTAR scores suggests that the latter scale adds useful information for assessing the health priorities of disabled CLBP patients.

Evaluation of responsiveness of Oswestry low back pain disability index.
To assess the response of Oswestry disability index (ODI) among patients undergoing caudal epidural steroid injections for lumbosacral radicular pain. ⋯ This study shows that ODI can detect small changes in disability over time in patients undergoing caudal epidural injections for lumbosacral radicular pain. It can also differentiate between small and large changes in the level of disability.
