Multicenter Study Controlled Clinical Trial
Establishing an optimal "cutoff" threshold for diagnostic lumbar facet blocks: a prospective correlational study.
Diagnostic medial branch blocks (MBB) are considered the reference standard for diagnosing facetogenic pain and selecting patients for radiofrequency (RF) denervation. Great controversy exists regarding the ideal cutoff for designating a block as positive. The purpose of this study is to determine the optimal pain relief threshold for selecting patients for RF denervation after diagnostic MBB. ⋯ Employing more stringent selection criteria for lumbar facet RF is likely to result in withholding a beneficial procedure from a substantial number of patients, without improving success rates.

In the recent years new technology has led to the development of a bewildering array of imaging procedures. Yet, conventional radiography remains one of the most used tools to diagnose and to aid procedural interventions. Fluoroscopy guidance facilitates targeted drug delivery or radiofrequency directly to the area of pathology, a benefit that has to be balanced against the risks of radiation exposure. ⋯ A correlation between weight and DAP was confirmed (r=0.230, P<0.05, Spearman's correlation coefficient). Patients with spinal pathology (n=33) had higher radiation exposure than those without (DAP median=0.85, U=978.00, P<0.005, r=-0.28, Mann-Whitney test). The DAP values obtained compare favourably with the recommended doses for radiographs and other procedures, although they generally exceed the values for a chest X-ray.

Multicenter Study
A national survey of acute hospitals in England on their current practice in the use of femoral nerve blocks when splinting femoral fractures.
Missed compartment syndrome can have devastating long-term impact on a patient's function. Femoral fracture has been reported in 52-58% of acute thigh compartment syndromes in the existing literature. Time to diagnosis of compartment syndrome is cited as a key determinant of outcome. Use of femoral nerve blocks in splinting of femoral fractures may mask signs of early compartment syndrome. We present the attitudes of emergency department and orthopaedic staff in NHS trusts in England with regard to this issue. ⋯ Femoral nerve block is an under-utilised, effective mode of analgesia following femoral fractures. There is a low risk of associated compartment syndrome, but clinicians should be especially vigilant in high-energy injuries. We recommend that all acute trusts receiving trauma should have a protocol for the use of femoral nerve blocks agreed by the emergency and orthopaedic departments.

Multicenter Study Clinical TrialSafety and acceptability of suprascapular nerve block in rheumatology patients.
Suprascapular nerve block (SSNB) is a popular treatment for shoulder pain. To date, studies undertaken mainly describe the methods of performing the technique or are trials examining its efficacy. As a result, the numbers of blocks reported are small and therefore confidence in the safety of the procedure must be limited. ⋯ Patient satisfaction with the pain relief was high, with over 80% of respondents being satisfied or very satisfied with the result. SSNB is a very safe procedure in the outpatient setting, even among frail, elderly patients. Patients rate the satisfaction with the pain relief highly.
