Randomized Controlled Trial Comparative StudyRandomized Controlled Trial of Interscalene Block Compared with Injectable Liposomal Bupivacaine in Shoulder Arthroplasty.
Shortcomings of interscalene brachial plexus blockade include technical failure and rebound pain. Bupivacaine liposome injectable suspension, a sustained release preparation, is used for surgical-site administration. The purpose of this study was to evaluate these 2 postoperative pain management strategies in patients undergoing shoulder arthroplasty. ⋯ Therapeutic Level II. See Instructions for Authors for a complete description of levels of evidence.

Randomized Controlled Trial Comparative StudyVirtual Reality Compared with Bench-Top Simulation in the Acquisition of Arthroscopic Skill: A Randomized Controlled Trial.
Work-hour restrictions as set forth by the Accreditation Council for Graduate Medical Education (ACGME) and other governing bodies have forced training programs to seek out new learning tools to accelerate acquisition of both medical skills and knowledge. As a result, competency-based training has become an important part of residency training. The purpose of this study was to directly compare arthroscopic skill acquisition in both high-fidelity and low-fidelity simulator models and to assess skill transfer from either modality to a cadaveric specimen, simulating intraoperative conditions. ⋯ Both high-fidelity and low-fidelity simulation trainings were effective in arthroscopic skill acquisition. High-fidelity virtual reality simulation was superior to bench-top simulation in the acquisition of arthroscopic skills, both in the laboratory and in vivo. Further clinical investigation is needed to interpret the importance of these results.
