Objective. This study aims to assess peripheral nerve field stimulation as a treatment option for chronic pain and test for indicators of outcome. Materials and Methods. We reviewed all patients permanently implanted with peripheral nerve field stimulators over the past 24 months. A questionnaire was used to assess outcomes. ⋯ Most patients reported decreases in analgesic use after treatment. Pain relief was significantly and highly correlated with reduced analgesic intake and patient satisfaction. Conclusion. Peripheral nerve field stimulation is a safe, reversible, and effective treatment option for patients with chronic pain, particularly those under 60 years.

Low back pain with or without lower extremity pain is the most common problem among chronic pain disorders with significant economic, societal, and health impact. Epidural injections are one of the most commonly performed interventions in the United States in managing chronic low back pain. However the evidence is highly variable among different techniques utilized - namely interlaminar, caudal, transforaminal - and for various conditions, namely - intervertebral disc herniation, spinal stenosis, and discogenic pain without disc herniation or radiculitis. ⋯ The evidence based on this systematic review is limited for blind interlaminar epidurals in managing all types of pain except for short-term relief of pain secondary to disc herniation and radiculitis. This evidence does not represent contemporary interventional pain management practices and also the evidence may not be extrapolated to fluoroscopically directed lumbar interlaminar epidural injections.

Chronic back pain is among the most common patient complaints. Its prevalence and impact have spawned a rapidly expanding range of tests and treatments. ⋯ The limited studies available suggest that these increases have not been accompanied by population-level improvements in patient outcomes or disability rates. We suggest a need for a better understanding of the basic science of pain mechanisms, more rigorous and independent trials of many treatments, a stronger regulatory stance toward approval and post-marketing surveillance of new drugs and devices for chronic pain, and a chronic disease model for managing chronic back pain.

This study examined the role of pain catastrophizing, fear of movement and depression as determinants of repetition-induced summation of activity-related pain. The sample consisted of 90 (44 women and 46 men) work-disabled individuals with chronic low back pain. Participants were asked to lift a series of 18 canisters that varied according to weight (2.9kg, 3.4kg, 3.9kg) and distance from the body. ⋯ Fear of movement, but not pain catastrophizing or depression, was associated with greater repetition-induced summation of pain. The findings point to possible neurophysiological mechanisms that could help explain why fear of pain is a robust predictor of pain-related disability. Mechanisms of repetition-induced summation of activity-related pain are discussed.

Case ReportsA complication during caudal steroid injection.
Epidural injections in the lumbar spine are provided by caudal, lumbar interlaminar or transforaminal routes. Caudal epidural steroid injections are often used for low back pain. Fluoroscopic guidance has been frequently cited as a requirement for this procedure. In this case report, we demonstrate the importance of fluoroscopic guidance during caudal epidural injection. ⋯ A careful real time fluoroscopic monitoring should be applied with the injection of opaque material to minimize the risk of vascular injection.
