This masterful book from top experts provides clinical insights on reverse shoulder arthroplasty gleaned from hands-on refinement of shoulder replacement techniques. Years of significant biomechanical and clinical research yielded invaluable knowledge that led to important improvements in functional outcome and implant durability. Among these refinements were stronger polyethylene derivatives, better ingrowth technology, and improved connection devices. As the durability and longevity of implant technology increased, younger active patients became suitable candidates for this procedure. In fact, RSA has played a pivotal role in making shoulder arthroplasty the fastest growing implant technology. In the first two sections, the authors take the reader through the history and evolution of RSA, followed by step-by-step surgical techniques for specific injuries and conditions.
