Pdf Summary
Musculoskeletal (MSK) Ultrasound is the use of sound waves to identify pathology in tendons, ligaments, joints, muscle, and nerves. It is a useful tool for evaluating orthopedic disorders and offers advantages such as high spatial resolution, lower cost, no radiation exposure, real-time evaluation, and point of care use. However, it has limitations including the inability to evaluate internal joint derangements and structures obscured by bone. MSK Ultrasound is operator dependent and requires certain transducers and movements for optimal imaging. Different tissues have characteristic sonographic appearances, such as hypoechoic, hyperechoic, and anechoic, and recognition of these patterns is important for accurate interpretation. Bony and vascular landmarks can aid in locating tissues that are difficult to visualize. Soft-tissue structures have varying degrees of anisotropy, which affects the quality of the ultrasound image. Tendon pathologies commonly encountered include tendon ruptures and degenerative tendinosis. Tendinopathy is the more general term used when the nature of the tendon disorder is unknown. Tendonopathies exhibit enlargement, loss of fibrillar architecture, and increased Doppler flow. Tendon tears show atrophy, cortical irregularity of underlying bone, and sharp demarcations between tendon and anechoic space of the tear. Practitioners can use checklists and protocols to develop an efficient scanning technique. Basic structures of interest listed in the document for upper limb and lower limb examinations include tendons, nerves, joints, muscles, and ligaments. The document also includes references and guidelines for further information and resources.
