You may want a chance to look at some videos and papers on Wide Awake hand surgery before the congress.
The important papers below have links to videos.
Here is a link to free access to more WALANT papers and movies that are not included in this site http://handsurgery.org/Pre-Course.cgi
The papers are summarized in the Wide Awake hand surgery book with over 150 videos available at http://www.thieme.com/books-main/orthopaedic-surgery/product/4210-wide-awake-hand-surgery. I make no money on the book. All profits go to the AAHS lean and green effort created to decrease unnecessary garbage and cost in hand surgery.
