In the past five years, the techniques used in arthroscopic shoulder surgery have advanced exponentially. The basic principles are the same, but the theories, techniques, and instrumentation have dramatically improved. "The Cowboy's Companion: A Trail Guide for the Arthroscopic Shoulder Surgeon" is truly a companion book to "Burkhart's View of the Shoulder: A Cowboy's Guide to Advanced Shoulder Arthroscopy", which builds on the principles of the first book and concentrates on the new theories and techniques that have developed since the first book was written. The book is separated into two sections: The Shoulder Roundup, which will be an update on the techniques and ideas that have developed in shoulder surgery and The Shoulder Rodeo, which will be a collection of challenging cases that demonstrate unique approaches to difficult shoulder problems. The text comes with two DVDs that feature advanced interactive technology. The surgical videos will be supplemented with state-of-the-art digitally enhanced illustrations and animations, to create an entirely new 3-dimensional learning environment for the surgeon.
