Review Meta AnalysisUltrasound-Guided Interventional Procedures in Pain Medicine: A Review of Anatomy, Sonoanatomy, and Procedures. Part V: Knee Joint.
Ultrasound-guided injection in pain medicine is emerging as a popular technique for pain intervention. It can be applied to the intra-articular injection of the knee joint. The first objective of this review was to describe and summarize the anatomy and sonoanatomy of the knee and associated structures relevant for intra-articular injection. The second objective was to examine the feasibility, accuracy, and effectiveness of injections as well as injection techniques.

Development of an Ultrasound Phantom for Spinal Injections With 3-Dimensional Printing.
This report describes a method for producing anatomically detailed, low-cost ultrasound phantoms of the spine with 3-dimensional printing. An implementation that involves representing a portion of the lumbar spine and the ligamentum flavum with 2 different printing materials and the surrounding soft tissues with agar gel is presented. ⋯ Ultrasound phantoms that are derived directly from patient anatomy have strong potential as learning tools for ultrasound-guided spinal insertions, and they could be used as preprocedural planning tools in cases involving pathologies, implants, or abnormal anatomies. Three-dimensional printing is a promising method for producing low-cost phantoms with designs that can be readily shared across clinical institutions.

Randomized Controlled TrialAdherence to guidelines for the management of local anesthetic systemic toxicity is improved by an electronic decision support tool and designated "reader".
A hardcopy or paper cognitive aid has been shown to improve performance during the management of simulated local anesthetic systemic toxicity (LAST) when given to the team leader. However, there remains room for improvement to ensure a system that can achieve perfect adherence to the published guidelines for LAST management. Recent research has shown that implementing a checklist via a designated reader may be of benefit. Accordingly, we sought to investigate the effect of an electronic decision support tool (DST) and designated "Reader" role on team performance during an in situ simulation of LAST. ⋯ In a prospective, randomized single-blinded study, a designated Reader with an electronic DST improved adherence to guidelines in the management of an in situ simulation of LAST. Such tools are promising in the future of medicine, but further research is needed to ensure the best methods for implementing them in the clinical arena.

Randomized Controlled Trial Comparative StudySubparaneural Versus Circumferential Extraneural Injection at the Bifurcation Level in Ultrasound-Guided Popliteal Sciatic Nerve Blocks: A Prospective, Randomized, Double-Blind Study.
Subparaneural injection for popliteal sciatic nerve block shows faster onset and longer duration than circumferential extraneural injection.
