The comparison of spread of methylene blue after the Pericapsular Nerve Group block and a double injection selectively targeting the articular branches to the anterior hip capsule in human cadavers.
Objectives: In this study, the spread of methylene blue was compared between an ultrasound-guided Pericapsular Nerve Group (PENG) block and a double injection technique, where the approach towards the inferomedial acetabulum was added to the latter.
Methods: The two techniques were performed in 11 fresh frozen cadavers. The spread was measured after anatomical dissection in which the supplying femoral and obturator nerves were identified.
Results and conclusion: Our study demonstrates adequate staining of the iliac bone with comparable distal and medial spread in both techniques, indicating that the PENG block with a single injection is adequate in blocking the hip capsule with 10 mL local anesthetics. Staining of the femoral nerve occurred in 2/6 specimens after the PENG block, and staining of the obturator nerve in 1 specimen in each group.
期刊介绍：
Pain Practice, the official journal of the World Institute of Pain, publishes international multidisciplinary articles on pain and analgesia that provide its readership with up-to-date research, evaluation methods, and techniques for pain management. Special sections including the Consultant’s Corner, Images in Pain Practice, Case Studies from Mayo, Tutorials, and the Evidence-Based Medicine combine to give pain researchers, pain clinicians and pain fellows in training a systematic approach to continuing education in pain medicine. Prior to publication, all articles and reviews undergo peer review by at least two experts in the field.
