54 unipolar prostheses and 61 bipolar prostheses with same femoral stem were examined clinically and radiologically at an average of 34 months postoperatively. The average age of the patients in unipolar group was 74 years
and
71
years in bipolar group. all prostheses had been inserted due to femoral neck fractures. There were two cases of dislocations two cases of acetabular erosion in method in unipolar group, meanwhile open reduction was required in bipolar group.
One case of early failure was found in emented bipolar arthroplasty at post-op 2 years follow-up. Functionally, the results were excellent and good in 70.4% of unipolar groun and in 73.8% of blpolar group. There was no signifecant
difference
between unipolar and bipolar arthoplasty.
