[Posterior dislocation of the hip associated with fracture of the neck of the femur. Apropos of 3 cases].

Three patients with posterior dislocation of hip associated with fracture of neck of femur were treated by early sanguineous reduction and osteosynthesis. This therapy was very effective since necrosis did not develop either in the short or long-term follow up (1, 3 and 4 years). These findings combined with documented data are in favor of anatomic reconstruction of upper end of femur by stable and solid osteosynthesis, at least in young adults. Early operation, an irreproachable operating tactic (orthopedic table, ventral decubitus, posterior approach), an immediate stable and solid synthesis and a deferred load bearing (beyond 6 months) should reduce the risk of femoral head necrosis to a minimum.
