The snapping hip has been defined as hip pain accompanied by an audible or palpable clicking or snapping during joint motion or walking. This syndrome... 

At the lateral aspect of the hip, extra-articular snapping hip can be secondary to intermittent impingement of the posterior border of the fasciae latae or the anterior portion of the gluteus maximus over the osseous prominence of the greater trochanter. The clinical appearance is nearly similar to that already described for the snapping iliopsoas tendon but with the patient referring symptoms over the lateral aspect of the hip. This condition can be painful or...

In this chapter, we focus on the traumatic injuries of tendons and ligaments in childhood. Other pathologies affecting these structures that are specific to children are addressed elsewhere in the book, including snapping hip (see Chapter 12), trigger thumb (see Chapter 11) and tenosynovitis (see Chapter 3). 

Fig. 12.33a,b. Snapping iliopsoas tendon. Schematic drawings illustrate the mechanism of the snapping iliopsoas tendon, a When the hip is flexed, externally rotated and abducted, the iliopsoas tendon (asterisk) shifts laterally relative to the iliopectineal eminence (IE), b When the hip returns to an extended position, the iliopsoas tendon (asterisk) impinges against the iliopectineal eminence until snapping over it and moving suddenly medially.
