Abstract
A case of a fractured ceramic femoral head without subsequent trauma, 14 months after a primary total hip arthroplasty, in a 40-year-old woman with hip dysplasia is reported. Intraoperative findings were multifragment femoral head and a damaged polyethylene insert along with diffuse metallosis and excessive wear of the cone of the stem. Both the stem and the acetabular component were stable. After the removal of ceramic fragments, metallotic tissue excision and careful lavage of the joint, the inlay was replaced by a similar one and a cobalt–chromium femoral head was placed to the existing notched taper of the firmly incorporated stem. At 22-month follow-up examination, the patient had no pain, used no walking aids and had normal activity.
