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:

  • posterior hip dislocation (most common ~85%)
  • anterior hip dislocation (~10%)
    • inferior (obturator) hip dislocation (rare)
    • superior (pubic/iliac) hip dislocation
  • central hip dislocation (protursio) - always associated with acetabular fracture 2,3
Aetiology
Acquired

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

Hip dislocation is the second most commoncomplication 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 ofdevelopmental dysplasia of the hip (see article for further information) 4

Complications

avascular necrosis: particularly if reduction postponed more than 24 hours
