Clinical TrialTreatment of pain from osteoporotic vertebral collapse by percutaneous PMMA vertebroplasty.
Vertebral compression fractures are common complications in advanced osteoporosis. In general, this disease of the elderly patient is characterized by severe local back pain. Pathophysiologically, bony instability triggers local pain during body movement. Serious pain immobilizes the patients and forces them to bed rest. As a result, complications like thrombosis or pneumonia occur. Invasive treatment with surgical instrumentation for vertebral stabilization is not indicated in elderly patients especially with additional diseases. The purpose of this study was to test the hypothesis that percutaneous polymethylmethacrylate (PMMA) vertebroplasty significantly reduces pain due to vertebral collapse in osteoporotic patients and improves quality of life. ⋯ PMMA vertebroplasty is a useful and safe method of pain relief which rapidly regains quality of life for patients with osteoporotic vertebral compression.

A retrospective case series of primary care patients receiving Workers' Compensation (WC) for back pain. ⋯ Many individuals with a WC claim do not have a stable PCP relationship around the onset of their WRLBP episode. Those with PCP relationships uncommonly involve the PCP in their WRLBP, and if they do, it is usually later in the course because of persistent or recurrent symptoms. Disability outcomes appear to be similar regardless of whether a PCP was involved. However, PCP involvement is associated with greater medical costs, which may reflect confounding based on duration of symptoms rather than the nature of the care provided. Additional research is needed to understand how different patterns of care for patients with a WRLBP claim relate to outcomes and how these patients compare with individuals without such a claim, as well as the factors that lead patients to involve their PCP or not.

Review
[Visualisation of phantom- and backpain using imaging techniques. Implication for treatment].
If patients with chronic low back pain are stimulated in the painful region, an expanded representation of the back in the primary somatosensory cortex becomes visible that increases with chronicity. This "pain memory" might play an important role in the chronicity process. In patients with phantom limb pain, e.g. subsequent to the amputation of an arm or leg, a shift in the representation of neighboring areas into the deafferented area in primary somatosensory cortex has been observed. ⋯ The modulation of plasticity and phantom limb pain by anesthesiological manipulation, the use of NMDA receptor antagonists and opioids is presented. Behaviorally relevant stimulation, e.g. by the use of a myoelectric prosthesis or sensory discrimination training can also influence the cortical somatosensory pain memory. More recent studies focus also on brain areas such as the cingulate gyrus believed to be involved in the affective processing of pain.

Comparative Study
Patterns and trends in opioid use among individuals with back pain in the United States.
Secondary analysis of Medical Expenditure Panel Survey from 1996 to 1999. ⋯ The variation in overall opioid use among individuals with back pain with different sociodemographic characteristics and from different geographic regions suggested an opportunity to improve opioid prescribing patterns. The increase in the use of hydrocodone and oxycodone indicated a need to better assess the efficacy and safety associated with these drugs among individuals with back pain.

A single group design to examine reliability and validity of the Back Performance Scale. ⋯ The Back Performance Scale appears to be a reliable and valid outcome measure of activity limitation.
