Background
Snaping hip syndrome (SHS),
also known as coxa saltans (or dancer’s hip),
is a clinical condition characterized by an audible or palpable snap in the hip during certain movements,
which may be accompanied by pain.
Internal SHS is the most common type of snapping hip.
It affects predominantly athletes who do repetitive and extreme hip abduction and external rotation movements,
such as ballet dancers,
gymnasts and people doing martial arts. Internal SHS involves the musculotendinous iliopsoas unit.
The most frequently reported mechanism is snapping of the psoas major tendon (PT) on the superior pubic ramus after release of the medial fibers of the iliac muscle from a transient position between the PT and the superior pubic ramus. Other mechanisms: PT impingement on the anteroinferior iliac spine or on a paralabral cyst,
conflict between the components of a bifid PT.
