Modified lateral block of the suprascapular nerve: a safe approach and how much to inject? A morphological study.
This paper presents an evaluation of a modified lateral suprascapular nerve block with easy orientation, low risk of displacement of the needle, and with an assessment of 2 different volumes to propose an ideal volume for a successful block. ⋯ Based on this cadaver study, the lateral modified approach appears to be a safe technique for a suprascapular nerve block, which might be preferred as a single shot technique. A 5 mL volume appears sufficient to fill the supraspinous fossa and to reach the suprascapular nerve, which branches in this anatomical compartment.

Multicenter StudyFactors predicting success and failure for cervical facet radiofrequency denervation: a multi-center analysis.
The concept of radiofrequency denervation has recently come under question in light of several studies showing minimal to no benefit. One possibility proposed for these negative outcomes is poor selection criteria. Unlike virtually all other spine interventions, the factors associated with success and failure for cervical facet denervation have yet to be determined. The purpose of this study is to determine which demographic, clinical and treatment factors are associated with cervical facet radiofrequency denervation outcomes. ⋯ Selecting patients based on key clinical variables may increase the chance of treatment success for cervical facet radiofrequency denervation.

Randomized Controlled TrialEffect of lumbar flexion on the extent of epidural blockade.
This study examined the effect of lumbar flexion on the extent of the epidural block during lumbar epidural anesthesia. ⋯ Lumbar flexion has no clinically relevant effect on sensory spread during epidural anesthesia.

Posterior lumbar plexus block in children: a new anatomical landmark.
Posterior lumbar plexus block is a well established anesthetic technique for lower limb surgeries. Both magnetic resonance imaging and clinical prospective studies were performed to verify if a new palpable landmark could be used for lumbar plexus block in pediatric patients. ⋯ The sulcus formed by the division between the longissimus and the iliocostal muscles is a simple, direct, and easy-to-identify landmark for posterior lumbar plexus block in children.
