Abstract
We report a case of insert fracture and metal shell penetration by the inner head after ceramic-on-ceramic THA. A 67-year-old female underwent ceramic-on-ceramic THA (Osteonics Secur-Fit HA, Ceramic-on ceramic Bearing System, Stryker) in another hospital. However, she noticed pain and crepitation and first visited our hospital due to aggravation of pain. Radiograph showed insert fracture and metal shell penetration by the inner head, and she was admitted for revision. During the operation, the intra-articular area showed marked metallosis. In the anterior area of the metal shell, there was a hole due to penetration by the inner head. The metal shell was removed and the acetabulum was reconstructed by filling with reinforcement granules, followed by implantation of a KT plate.
