[Medical-legal aspects in fractured ceramic liners after implantation of a hip endoprosthesis].

We report the case of a male patient after implantation of a thrust plate endoprosthesis to discuss reliable questions concerning the insurance and liability fields. The indication for implantation of this type of endoprosthesis should be decided critically. To prevent an early implant failure, both articulating ceramic partners - the liner and the femoral head - should be exchanged in any case of doubt during a hip revision surgery. In case of an implant failure, a surface analysis of the broken fragments can show signs of material insufficiencies. A detailed preoperative consent of the patient combined with an exact documentation is necessary to prevent potential medical claims by the patient, and also increases the compliance and reduces the costs for the health system.
