- Discussion:
- most useful for assessment of
loosening of
acetabular component;
- for acetabular component, contrast at the cement bone interface in all zones or in zones I and II
or II and III may be associated w/ loosening in 90% of components;
- if there is a rim of contrast material > 2 mm in any one zone about acetablar component, 95% of
components will be loose;
- for femoral component, 98% are loose, if there is contrast at cement bone interface distal to the
intertrochanteric line or beyond the mid point of a long stemmed component;
- 95% are loose if there is contrast below the intertrochanteric line at the cement prosthesis interface;
