Introduction
Interscalene brachial plexus blocks are a common modality utilized to provide adjunctive pain relief with shoulder replacement surgery. In 2018 the Federal Drug Administration approved the use liposomal bupivacaine (LB) for such nerve blocks. We sought to evaluate whether this formulation of bupivacaine would provide superior pain reli...
In conjunction with neurofibromas, schwannomas are the 2nd most commonly occurring intradural extramedullary tumor. They are a benign encapsulated nerve sheath tumor that are typically slow growing. They occur equally as frequently in the cervical and lumbar spine. If symptomatic, surgical resection may be warranted. In this surgical technique vide...
