This book focuses on musculoskeletal ultrasound teaching files. The concept of a general musculoskeletal ultrasound case-based book arose from work experience in musculoskeletal ultrasound and close interaction with the orthopedic colleagues over the years. The authors have selected well over 82 cases with nearly all common complaints afflicting muscles, bones, joints, soft tissues, tendons and ligaments with which a patient may walk into the clinic for diagnosis and treatment. Although, these cases may represent just a sample in the spectrum of related pathologies, they amply illustrate the importance of ultrasound as an important diagnostic tool in evaluating musculoskeletal system complaints, as also raising the bar in patient care. The case series are a celebration of how ultrasound has evolved to a position of awe and credibility in today’s highly specialized world dominated by magnetic resonance imaging (MRI) and computed tomographs (CTs). Each case begins with a clinical history followed by ultrasound images with their description, diagnosis and relevant discussion pertaining to the case. Case discussion stressed on relative anatomy and certain points that need to be incorporated within the report, so that all the relevant information is conveyed to the referring orthopedic surgeons and physicians. This book provides a pleasant experience to the readers and provides answers quickly and easily when they need them.
