The total hip
replacement after failure of hemiarthroplasty (unipolar or bipolar) has been
associated with very high rates complications (intra- and postoperative).
Forty patients 24
males and 16 females with a mean age of 58 years (range: 48-68)
had total hip arthroplasty (THA) revision of aseptic loosening of hip
hemiarthroplasty.
The mean duration
of the follow-up was 42 months (range: 30-72), and the cases lost in follow up
were excluded from the study. Failure was defined as revision arthroplasty or
radiographic evidence of stem loosening, indicated by an Engh fixation score ≤
10. Vertical femoral migration of >5 mm was defined as subsidence.
