Dislocation of the hip
Management of
femoral head fracture by Ganz surgical dislocation of the hip. A, B Preoperative radiograph of a male 28-year-old patient with right hip dislocation and fracture of the femoral head (Pipkin type 2 fracture)
Zentrale
Hüftluxation bei einer 40-jährigen. Der Hüftkopf ist im Sinne einer Luxationsfraktur nach zentral durch das Azetabulum eingebrochen und verlagert hier die Fragmente gegen das Beckeninnere. Links Computertomographie in koronarer Rekonstruktion, rechts Volumen-Rendering-Darstellung des linken Hemipelvis mit Blick von innen.
Traumatische
hintere Hüftluxation links ohne eindeutige ossäre Verletzung des Acetabulums. Man erkennt jedoch in der sagittalen Rekonstruktion (links unten) die (geringe) Impression des hinteren Pfannenrandes in den Femurkopf (analog einer Hill-Sachs-Delle).

Hip dislocation is a relatively rare entity and may be congenital or acquired.
Epidemiology
Hip dislocations account for ~5% of all dislocations .
Pathology
There are numerous patterns of dislocation :
- posterior hip dislocation (most common ~85%)
- anterior hip dislocation (~10%)
- inferior (obturator) hip dislocation
- superior (pubic/iliac) hip dislocation (rare)
- central hip dislocation (protrusio) - always associated with acetabular fracture
Etiology
Acquired
Acquired hip dislocation is normally associated with high-speed trauma, with motor vehicle collisions account half of the dislocation with other causes such as falls and sports injuries, less common .
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 .
Congenital
Congenital hip dislocation is now considered part of the spectrum of developmental dysplasia of the hip (see the article for further information) .
Complications
- avascular necrosis: particularly if reduction postponed more than 24 hours
