Success in shoulder arthroplastic surgery is not necessarily dependent only on the principle of construction of a prosthetic device, nor on the way this device is implanted or fixed to the bony interface, but more so on the understanding and handling of the soft tissues surrounding the articulation. Based on their experience in basic anatomy and function, the editors of this book were able to develop a prosthetic device which can take into account individual anatomical variations in each patient, making a successful outcome of surgery much more predictable. This must-have for any shoulder surgeon not only informs on the current state-of-the-art, but also provides an understanding of what advances can be achieved with innovative thinking in the field of orthopaedic surgery.
