Lining up the liner: 2 case reports of early ceramic liner fragmentation.
We present 2 cases of early ceramic liner fragmentation in patients undergoing ceramic-on-ceramic uncemented total hip arthroplasty. The reports highlight the significance of correct liner insertion at the time of operation and the importance of a meticulous evaluation of postoperative radiographs. Tilting of the liner may not be visualized on the anteroposterior roentgenogram alone. Preradiological ceramic fragmentation can occur.
