The bipolar prosthesis was developed to overcome some of the shortcomings of the unipolar fixed-head prosthesis. An additional site of motion would be expected to decrease the amount of loosening, dislocation, and head migration. Although clinical series have shown success rates for bipolar prostheses as good as those for unipolar prostheses, the intended advantages have not been clearly demonstrated.
