A polyethylene liner dissociation case report in depuy pinnacle cup. An impingement problem?

Alvaro Martinez-Ayora, Guillermo Sosa-Gonzalez, Carlos Luis Vidal-Fernandez.

Abstract
The modular components facilitate joint replacement surgery but are associated with potential complications not present in the previous components. We present a case of polyethylene dissociation due to rupture of the anti-rotational blocks in a total hip prosthesis two years after surgery. We think about the possible causes and risk factors. Despite its low incidence, the dissociation between polyethylene and the acetabular cup is a catastrophic complication. The femoroacetabular impingement seems to play a key role.

Key words: Total hip arthroplasty, liner dissociation, femoroacetabular impingement
