The book begins with a history of RSA followed by a thorough overview of the basic science and biomechanics of the shoulder. Indications for and clinical applications of RSA in a number of surgical interventions are then described, including the revision of failed shoulder arthroplasty, setting in cases of glenoid and humeral bone loss and rotator cuff tears. A whole section is then dedicated to various commercial devices with descriptive expert analysis of the design and implementation of each. An examination of the current economic value of RSA, including cost effectiveness and expected cost outcomes, comprises the final section. Reverse Shoulder Arthroplasty can therefore be read either from start to finish, allowing orthopedic surgeons to appreciate the various perspectives offered, or by selecting specific topics of interest much like a “how-to manual” of either a particular device design or the treatment of a specific pathology.
