snapping hip syndrome

Snapping hip syndrome (also known as coxa saltans or dancer’s hip) refers to a situation where there is an audible snapping sound produced during motion of the hip.

Epidemiology

Some reports suggest that up to 10% of population may have this to some degree .

Pathology

This condition is classified into external, internal, and intra-articular types, with the external type being the most common.

Extra-articular causes

• lateral
  • iliotibial band snapping over the greater trochanter (proximal iliotibial band syndrome - not always audible)
  • gluteus maximus snapping over the greater trochanter
• medial
  • snapping iliopsoas tendon from abnormal intrinsic movement, or snapping over the iliopectineal eminence.

Intra-articular causes

• synovial osteochondromatosis
• intra-articular loose bodies
• acetabular labral tears
• osteochondral fractures
• transient subluxation of the femoral head
