Body was changed:

Hip dislocation is a relatively rare entity and may be congenital or acquired.

Epidemiology

Hip dislocations account for ~5% of all dislocations 3

Pathology

There are numerous patterns of dislocation 1:

Hip dislocation can be further classified as being simple (pure without associated fracture) or complex (dislocation associated fracture of the acetabulum or proximal femur) 6

Aetiology
Acquired

Acquired hip dislocation is normally associated with high-speed trauma, with motor vehicle collisions accounting for half of the dislocations with other causes such as falls and sports injuries, less common 1.

Hip dislocation is the second most common complication of hip joint replacements and occurs in ~5% (range 0.5-10%) of patients with ~60% of dislocations being recurrent 5

Congenital

Congenital hip dislocation is now considered part of the spectrum of developmental dysplasia of the hip (see this article for further information) 4
