Ultrasound has been described as the “stethoscope” of the radiologist; its ability to aid in clinical diagnosis with both static and dynamic imaging has allowed fast and accurate diagnosis. However, traditionally unlike a stethoscope, a large and bulky ultrasound machine made it difficult to use portably in a hospital environment where patients can be scattered across a hospital. With the development of innovative ultrasound technology, Point of Care Ultrasound (PoCUS) can readily be carried by a clinician to make a quick and timely diagnosis. In this review article we look at the uses of PoCUS within orthopaedic emergencies. Diagnosis in orthopaedics often requires further imaging beyond history taking, clinical examination and plain radiographs. In these cases PoCUS can be useful for ruling out occult fractures, diagnosing joint effusions and tendon ruptures. By aiding a speedy diagnosis, we can reduce unnecessary immobilisation, reduce inpatient stays, introduce early mobilisation and reduce harm to patients. With PoCUS becoming increasingly cheaper and more portable we feel this really can become the stethoscope of an orthopaedic surgeon.
