A ceramic liner fracture during total hip arthroplasty: a case report.

The ceramic-on-ceramic bearing has been a reliable bearing option in total hip arthroplasty (THA) for both elderly and younger patients with a long life expectancy. However, ceramic bearings are at risk of fracture. This case describes a complication during THA involving the use of a cementless press-fit acetabular shell and ceramic liner for a woman with bilateral avascular necrosis and collapse. Ceramic liner fracture occurred during its insertion owing to nonconcentric reduction. Our case report helps to expand the understanding of this rare complication of THA: ceramic liner fracture can occur intraoperatively.
