<prompt> All of the following is true about dashboard injury except:It is associated with posterior dislocation of the hipSciatic nerve may be involved leading to foot dropAvascular necrosis of the hip could be a late complicationThe point of impact is on the greater trochanter  <response>: Posterior Dislocation and Fracture-Dislocation-Dashboard injury Dashboard Injury is associated with Post. dislocation PCL avulsion Present with a shoened, internally rotated, adducted limb in slight flexion. It is associated with a fracture of the femoral head or acetabulum. The sciatic nerve lies behind the posterior wall of the acetabulum- may be damaged in a posterior dislocation of the hip resulting in foot drop and other symptom. The force is transmitted up the femoral shaft NOT the greater trochanter.
