Objective: The present study was performed on cadavers to evaluate the efficacy of the different supraclavicular block techniques (Vongvises, Dalens, plumb-bob and inter-SCM) by investigating the location of the needle tip on the brachial plexus and to determine the most suitable block techniques according to the site of the surgery.
Methods: The study was performed on one embalmed and nine fresh cadavers. After the dissection, the skin of the cadavers was restored in its original position.
