Aseptic loosening of the components has been the most significant and frequent long term problems in cemented total hip arthroplasty. Recently some surgeons, such as Harris, has improved the function of the cemented total hip
prostheses by centrifuging of the cement and improvement of the techniques for cementing. Wthersurgeons, such as Engh, started to use cementless components to achieve direct bonding detween the component and surrounding bone by biological
ingrowth. In older age group(65 years of age or older), cemented total hip arthroplasty has been the gold standard and the results are excellent. However, during performing cemented total hip arthroplasty, a few serious
medical
complications, such as hypotension and rarely cardiac arrest, may occur. The anesthesia and operation time may be longer in cemented total hip arthroplasty than those of cementless ones. The purpose of this study any differences in
clinical
and radiologic results between cementless femoral stom and cemented femoral stem.
We performed total hip arthroplasties in 82 patients who were 65 years of age or older from May 1985 to December 1990. Thirty-five(39 hips) patients who could be followed more than w years were included for this study. Twenty-three patients(25
hips_
had cementless total hip arthroplasty and 12 patients(14 hips) had hybrid total hip arthroplasty.
We could not find any significant differences in results between hybrid and cementless total hip arthroplasty.
