ABSTRACT
PURPOSE:
The purpose of this study was to compare the two-dimensional with three-dimensional radiographic measurements of polyethylene liner wear in the Harris-Galante II acetabular cup. MATERIALS ANDMETHODS:
We measured the polyethylene liner wear amount and the wear rate of 64 hips with Harris-Galante II acetabular cup by twomethods:
Livermore's method and modified Devane's method. We evaluated the relationships between the two methods.RESULTS:
The average total amount of wear and the average wear rate are 0.86+/-1.01 mm and 0.18+/-0.20 mm/year using the two-dimensional method and 0.99+/-1.01 mm and 0.21+/-0.2 mm/year using three-dimensional method respectively. The amount of wear and the wear rate by the three-dimensional method was larger than those by the two dimensional method.CONCLUSION:
The amount of polyethylene liner wear can be measured by the two-dimensional method because it is highly correlated with the amount that is measured by the three-dimensional method, since there was no differences between the two methods.
