Results from high-energy trauma (e.g. dashboard to flexed knee)
Can occur with dislocation:
Posterior dislocation
Affected leg appears shortened, internally rotated, adducted
Fracture of inf aspect of femoral<unk> ; concomitant sciatic nerve injury
Anterior dislocation
Affected leg appears shortened, externally rotated, abducted
Fracture of anterior femoral<unk> ; concomitant vascular injury
Associated Conditions:
Femoral neck fracture
acetabular fracture
sciatic nerve neuropraxia
ipsilateral knee ligamentous instability
