140 patients with Garden III or IV fractures of the femoral neck were randomized to receive either a short anatomical cementless stem or a conventional cementless stem. At four year follow-up, it was found that the two groups did not significantly differ in regards to Harris Hip or WOMAC scores.

The conventional group also had significantly more patients with pulmonary microemboli and intra-operative undisplaced fractures of the calcar.
