Intrapelvic protrusion of the ceramic head resulting from forte ceramic liner fracture without a significant trauma: a case report.

In this article, we present a 48-year-old female case who had an unsuccessful previous forte ceramic-on-ceramic total hip arthroplasty for early coxarthrosis secondary to acetabular dysplasia. She had fracture and protrusion of the ceramic liner through the titanium acetabular shell without any apparent trauma, possibly resulting from the mistake during the implantation of the ceramic liner into the metal shell in the initial operation. The patient had no other risk factors (component malposition, trauma, malalignment) for ceramic liner fracture. She underwent revision surgery with allograft, reinforcement ring, all-polyethylene cup and reinforced stainless-steel femoral head.
