The idea of this book is very simple. Nowadays, there are many good, very comprehensive, "thick" books available on Elbow Surgery. Although they are useful to obtain discrete information about specific topics, they are too large to be a user friendly for a general orthopedic surgeon facing common elbow problems. The increasing interest among young surgeons on elbow problems is remarkable. It has been our experience throughout the years, teaching our residents and visitors, that there is a real demand for a less extensive book, easy to read, and with practical information about the most commonly encountered problems of the elbow. This text would be enough to understand the common elbow practice for a general orthopedic surgeon and a guide to learn basic elbow surgery during training. There is nothing like this available today. It will be strongly oriented to practice, and all the authors, well known internationally for their expertise on elbow surgery, will be homogeneous in their message.
