[A cup adjusted to cylindrical pressure: treatment of choice of idiopathic necrosis of the femoral head without arthritis (author's transl)].
68 cases of necrosis of the femoral head without arthritis were treated by Luck's prosthesis with cylindrical weight bearing which gives it great stability on the stump of the neck of the femur. This series included only 6 failures, (4 immediate failures and 2 late failures) which occurred within the first 2 years. The cup proved to be stable on the femur and did not affect the acetabulum. 4 of the failures were due to technical mistakes (neck too long, cup fitting badly) and could have been avoided. There were thus only two true failures. The length of the follow up which reached eight years for the oldest cases, permitted us to propose this treatment of necrosis of the femoral head in all cases where the head was deformed without waiting too long and discharging the patient, the onset of arthritis then modifies the problem.
