Lumbar selective nerve root blocks have been performed to establish the origin of lumbar radiculopathy in clinically difficult cases. The diagnostic ability of selective nerve root blocks remains controversial because of concern over potential spread of an injectate onto adjacent structures. ⋯ Injection of 1 ml of contrast under fluoroscopic guidance does not guarantee selective spread of the contrast around L4 or L5 nerve roots only. There is also spread toward the more medial nerve root in the same spinal segment during L4 and L5 nerve root infiltration. These findings suggest that it is possible to differentiate between L4 and L5 nerve root pathology using a sequential nerve root blocks under fluoroscopic guidance.

Spinal injections are commonly used to treat lumbar radiculitis and back pain. Delivery of medication to specific targeted pathology is considered important for a successful therapeutic outcome. A variety of routes of injection have been devised for epidural injection of corticosteroid. ⋯ The radiographic findings demonstrate a difference between classic infra-pedicular versus retrodiscal transforaminal epidural contrast injection patterns, particularly at relatively low volumes. The clinical advantage of one technique versus the other should be established in randomized prospective studies.

Our study was designed to document fiscal data for emergency department admissions for acute exacerbation of chronic back pain. ⋯ Emergency department care may be a costly venue for the management of chronic back pain. Because most patients obtain only short-term relief, they are likely to continue seeking urgent care intermittently until effective long-term pain management is widely available and reimbursable on an outpatient basis.

There has been growing interest among researchers and clinicians in the role of ambivalence over emotional expression (AEE) in adjustment to chronic illness. Because of the salience of anger in chronic low back pain, this condition provides a particularly good model in which to examine the role of AEE. This study examined the relation of AEE to pain and anger in a sample of 61 patients with chronic low back pain. Patients completed standardized measures of AEE, pain, and anger. Correlational analyses showed that patients who had higher AEE scores reported higher levels of evaluative and affective pain as well as higher levels of state and trait anger and the tendency to hold in angry thoughts and feelings. Mediational analyses revealed that most of the associations between AEE and pain, and AEE and anger, were independent of one another. These findings suggest that a potentially important relationship exists between AEE and key aspects of living with persistent pain. ⋯ This preliminary study suggests that there is a relation between ambivalence over emotional expression and pain and anger in patients with chronic low back pain. Patients who report greater conflict with regard to expressing emotions may be experiencing higher pain and anger.

Randomized Controlled Trial
Total dorsal ramus block for the treatment of chronic low back pain: a preliminary study.
To evaluate the use of total dorsal ramus block, which blocks all three major branches (medial, intermediate, and lateral branches) of lumbar dorsal ramus, for chronic low back pain. ⋯ The results of this preliminary study show that the total dorsal ramus block procedure may sufficiently block all three branches of the lumbar dorsal ramus at the targeted level with significant pain reduction.
