Abstract
|
|
|
The objective was to determine if titanium(Ti) alloy was a suitable material for a
cemented titanium femoral stem. Secondary objectives were to examine the effects of stem position and offset. Two hundred and thirty-eight cases of the hip were treated with a heavy cemented Ti alloy stem. These cases have been followed for 5-8
years.
They were rated clinically with a Harris hip score and radiologically after the fashion of Gruen. Twenty-eight patients died at less than 5 years and 12 were lost to follow-up Sixty-one cases were hip revisions and were thus considered separately
as
were 27 primary cases with a smooth threaded acetabular component. Of the 129 primary cases with a cemented acetabular component, only 1 case required revision and this was for acetabular loosening only. The Harris hip rating for the others was
75.8%
excellent, 18.7% good, 2.3% fair and 3.7% poor. Radiologic rating was high grade (4 zones) in 1 bilateral case and low grade in 7.7%, mainly single zone. Varus or valgus insertion did not influence outcome, nor did plug placement or stem offset.
It
is
concluded that with appropriate stem design Ti alloy is a suitable material for cemented total hip replacement.
