<abstract xmlns="http://www.w3.org/1999/xhtml"><p>Snapping hip syndrome is an audible or palpable snap in a hip joint during movement which may be accompanied by pain or locking. It is typically seen in young athletes performing activities requiring repeated extreme movements of the hip. It may also follow a physical trauma, intramuscular injections or surgeries. There are two main forms of snapping hip: extra- or intra-articular. Extra-articular snapping hip is elicited by an abnormal movement of specific tendons and is divided into two forms: internal and external. The internal form of snapping hip syndrome is attributed to an abrupt movement of an iliopsoas tendon against an iliopectineal eminence. Radiograph results in patients with this form of snapping tend to be normal. Dynamic ultrasound is the gold standard diagnostic technique in both forms of extra-articular snapping hip syndrome. The objective of the following text is to describe a step-by-step dynamic ultrasonography examination in internal extra-articular snapping hip syndrome in accordance to the proposed checklist protocol. To evaluate abrupt movement of an involved tendon, the patient needs to perform specific provocation tests during the examination. With its real-time imaging capabilities, dynamic ultrasonography detects the exact mechanism of the abnormal tendon friction during hip movement in a noninvasive way.
