Unfortunately the statement in the Methods section on page 22 that 'All blocks were performed by one investigator (H. K.) using the interscalene approach described by Winnie and colleagues ' is incorrect because axillary plexus block, not interscalene block, was used in the investigation. This sentence should be replaced by 'All blocks were performed by one investigator (H. K.).' This error, for which the authors accept responsibility, is very much regretted.
