Figs. 3-A through 3-D Previously described in a case report⁶, these components were retrieved from a patient after sixty months because of pain and squeaking.

Osteolysis in third-generation alumina ceramic-on-ceramic hip bearings with severe impingement and titanium metallosis. J Arthroplasty. 2008 Apr 2. E pub ahead of print.) Fig. 3-A There is evidence of impingement of the neck of the femoral component against the retrieved acetabular shell. Fig. 3-B Opposite the point of impingement on the rim, there is edge loading of the ceramic insert and a corresponding area of wear on the femoral head (the wear area has been colored with a blue surgical marking pen).
