Total hip replacement following failed femoral hemiarthroplasty.

Total hip-replacement arthroplasty performed for failed femoral hemiarthroplasty achieved results that were as good as those of the same operation done for other conditions. In forty-one patients who underwent such a procedure and who were followed for an average of three years, there was marked improvement in pain rating and range of motion. However, there were more cases of progressive loosening of the prosthesis than occur ordinarily, and three revisions had to be done. Fixation of the femoral component with cement was complicated by the presence of the fibrous membrane and bone deficiency preoperatively.
