ABSTRACT
The use of ultrasound in imaging the musculoskeletal system is widespread and has a number of different applications. The most important anatomical landmark in ultrasound of the hip is the anterior recess – a ‘pocket’ between two layers of synovium at the anterior aspect of the femoral neck. The primary role of ultrasound at the hip joint is to assess for the presence of a joint effusion and to guide aspiration of any excess fluid for cytology. The role of ultrasound is primarily in assessing the superficial anterior ligaments and looking for joint effusion. The approach to ultrasound of the knee joint is similar to that of the hip joint, and getting yourself orientated is key. Patients may present with focal areas of pain, redness or swelling on and around their ankle, and ultrasound is a really useful tool to evaluate specific areas of discomfort or abnormality.
