| Abstract: | A case of bilateral fractures of both ceramic heads in total hip arthroplasty and subsequent re-fracture of ceramic component after revisional surgery with ceramic sandwich cup exchange is reported. The heads were a skirt-type and extra-long size. The fractures occurred 8 months after the operation without any trauma. The cause of the fractures might be the impingement between the neck and the ceramic liner rim. At revision surgery, the fractured ceramic heads were replaced with sandwich-type ceramic liner and heads with ball type. After 3 years of revision surgery, ceramic head and ceramic liner in left total hip arthroplasty were fractured without any trauma. The ceramic head and liner were replaced with metal head and polyethylene liner at re-revisional operation. |
