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.

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.

Case ReportsStimulating catheter as a tool to evaluate peripheral nerve function during hip rotationplasty.
Stimulating catheters have been introduced into clinical practice to confirm perineural localization of the catheters. The muscular twitch induced over the catheter may be used to evaluate nerve function intraoperatively. Therefore, the function of the sciatic nerve was evaluated during major cancer surgery of the femur. ⋯ The use of epidural stimulating catheters as a tool to monitor nerve function is a novel and simple procedure to monitor nerve function intraoperatively and to enable good postoperative pain control.
