Review Meta Analysis
Systematic reviews of low back pain prognosis had variable methods and results: guidance for future prognosis reviews.
Systematic reviews of prognostic factors for low back pain vary substantially in design and conduct. The objective of this study was to identify, describe, and synthesize systematic reviews of low back pain prognosis, and explore the potential impact of review methods on the conclusions. ⋯ There is an immediate need for methodological work in the area of prognosis systematic reviews. Because of methodological shortcomings in the primary and review literature, there remains uncertainty about reliability of conclusions regarding prognostic factors for low back pain.

Multicenter Study Clinical Trial
Effectiveness of a low back pain classification system.
One goal of low back pain (LBP) assessment is to direct clinicians to specific subgroups that benefit from particular treatment approaches. ⋯ LBP is a heterogeneous condition and treatment results may significantly improve when clinically relevant syndromes are determined initially to guide treatment. Classifying LBP based on pattern recognition shows promise to help clarify future clinical trials and surgical referrals.

Randomized Controlled Trial
L2 spinal nerve-block effects on acute low back pain from osteoporotic vertebral fracture.
Elderly patients with osteoporosis sometimes experience lumbar vertebral fracture and may feel diffuse nonlocalized pain in the back, the lateral portion of the trunk, and the area surrounding the iliac crest. The pattern of sensory innervation of vertebral bodies remains unclear. Some sensory nerves from the L2 and L5 vertebral bodies may enter the paravertebral sympathetic trunks and reach the L2 dorsal root ganglion. Our randomized controlled study was to clarify the effect of L2 spinal nerve block on low back pain originating from acute osteoporotic lumbar vertebral fracture. Patients with low back pain originating from acute L3 or L4 osteoporotic vertebral fractures received a spinal nerve root block (L2 block group, n = 30) or subcutaneous injection (control, n = 30). Both groups received 1.5 mL of 1% lidocaine. The visual analog scale score, Roland Morris Disability Questionnaire, and Short Form questionnaire were examined before and after treatment. In both groups, spinal nerve blocks were significantly effective in alleviating low back pain (P < .05). One hour, 1 week, and 2 weeks after treatment, the visual analog scale score improved more in the L2 block group than in the control group (P < .05). From 1 month to 4 months after treatment, there were no significant differences in the pain scores between groups (P > .05). We conclude that L2 spinal nerve block for acute L3 or L4 osteoporotic vertebral body fracture was effective for 2 weeks, but it had no long-term effects on pain and social function. ⋯ L2 spinal nerve block treatment for L3 or L4 osteoporotic vertebral body fracture was effective. This results suggest that the L2 dorsal root ganglion may innervate the L3 and L4 vertebral bodies in humans. L2 spinal nerve block for lumbar osteoporotic vertebral fracture may be a useful strategy to treat acute low back pain.

Little is known about chronic low back pain (CLBP) in combination with widespread musculoskeletal pain (WMP). ⋯ Patients with CLBP and WMP should be examined for indicated physical and psychosocial factors. Therapeutic management should consider them in the early stage of the disease. These findings also might apply to patients with fibromyalgia or myofascial pain.

Review Meta Analysis Comparative Study
Sterile water injection for labour pain: a systematic review and meta-analysis of randomised controlled trials.
Up to one-third of labouring women will experience painful 'back labour'. Sterile water injected lateral to the lumbosacral spine is a simple and well-researched approach to this pain. ⋯ We believe that a large RCT should be mounted to validate our findings regarding the impact of sterile water injections on mode of delivery.
