This work includes lectures presented at the AAOS 2006 Annual Meeting in Chicago, Illinois. This volume continues the tradition of providing current and relevant information across a broad spectrum of orthopaedic medicine and surgery. Topics include: Shoulder, Hand and Wrist, Hip, Trauma, Spine, Sports Medicine and Adult Reconstruction. A 5 year cumulative index is included. The lectures are one of the longest running and most widely recognized orthopaedic publications (published annually, with a few exceptions, since 1943), and are based on the AAOS Annual Meeting's most popular clinical offerings. Also included with the ICL 56 is a DVD supplement with video excerpts from surgical procedures described in selected chapters of the book.
