This book combines orthopedists and radiologists perspectives to provide a comprehensive overview of the rapidly expanding use of ultrasound in orthopedic surgery. It also highlights the growing awareness of the potential of this non-invasive and portable, real-time imaging tool, which has led to its inclusion in the minimally invasive toolkit of upper limb surgeons. The book is divided into five parts shoulder, elbow, forearm, hand and wrist and fingers. Each part focuses on a particular anatomic region or joint, carefully analyzing the sonoanatomy of its nerves, tendons and bones. For each region, experienced experts illustrate how to perform specific techniques under ultrasound control, ranging from classic procedures, like carpal tunnel release, to the treatment of less common conditions.
