Ceramic liner fracture and impingement in total hip arthroplasty.

ABSTRACT:

Background

Ceramic-on-ceramic bearing surfaces were developed to provide an alternate to metal-on-polyethylene to decrease wear-induced osteolysis in total hip arthroplasty patients. In an effort to decrease the risk of ceramic acetabular component fracture or damage during implantation, a raised metal rim was added.

Questions/purposes

How many fractures or impingements have occurred in our population of patients with ceramic liners with raised rims?

Methods

With IRB-approved consent, a case series was reviewed from a single center registry and 4 of 169 patients were identified who had revision hip surgery with the ceramic liner with a raised metal rim: one for ceramic liner fracture and three for metallosis, pain, and squeaking.
