Now in a fully revised and expanded second edition, this practical text presents the current state of the art and latest advancements in the biomechanics, assessment, diagnosis and management of UCL injury in the elbow. In the years since this book initial publication, significant developments have occurred on multiple fronts relating to elbow UCL injury, including injury prevention, less invasive repair techniques, more anatomical surgical reconstructions, and improved post-injury rehabilitation protocols. Chapters are once again arranged thematically, beginning with discussion of the relevant anatomy and surgical approaches, throwing biomechanics and overload mechanisms, epidemiology, history and physical exam. After a description of the radiological approaches to assessment, both conservative and surgical strategies are outlined and discussed in detail, from repair both with and without augmentation to reconstruction both arthroscopically and with newer minimally invasive techniques. Considerations for UCL injury in special populations – the young athlete and the female athlete – and sports-specific rehabilitation, return-to-play and prevention via wearable technology round out this thorough presentation.  Enhanced with select video clips illustrating surgical techniques, Elbow Ulnar Collateral Ligament Injury, Second Edition remains a go-to resource for orthopedic surgeons, sports medicine specialists, therapists and trainers who work with athletes that suffer from these conditions.
