Abstract
In total hip arthroplasty ceramic bearings are liable to fracture. We present the case of an 82-year-old male with groin pain and an audible squeak 6 months post ceramic on ceramic hip arthroplasty. Initial plain radiography and examination under anaesthetic (EUA) were normal. Fluoroscopy with normal image exposure was also unremarkable. Over penetration of the image intensifier film demonstrated a fracture of the ceramic acetabular liner. The patient subsequently underwent a revision of both acetabular and femoral bearing surfaces.Displaced ceramic liner fractures are easy to identify with plain radiographs. We recommend the use of over penetration using image intensification as a technique to help identify subtle ceramic liner fractures. To our knowledge this has not been previously reported in the literature.
