Loose right total hip prosthesis

Case contributed by Jack Ren

Presentation

Loose right femoral component.

Patient Data

Age: 70
Gender: Female
Modality: X-ray

Bilateral cemented total hip prosthesis. Ideally comparison would be made with previous films but note the steepness of the right acetabular cup compared to the more normal angle of approximately 50to horizontal on the left. This may be due to poor positioning at the initial surgery or because the cup has rotated.

Lucent regions are seen between the cement and bone along the mid and distal femoral stem. There is also lucency between the shoulder of the right femoral stem and the greater trochanter indicating subsidence. Findings are those of loosening of both the right acetabular and femoral components. The left hip replacement is normal.
