Catastrophic Disassociation of Ceramic Femoral Head and Neck Trunnion Caused Iatrogenically

Understanding the patient's surgical history and the specifics of previously used implants is crucial in partial revision total hip arthroplasty (THA).The authors report a patient 13 years post-THA who experienced dissociation between the ceramic head and the femoral stem trunnion.This complication was deemed iatrogenic, arising from insufficient information on the original prosthesis and an unclear medical history.This case underscores the need for comprehensive knowledge of the implanted prosthesis during partial revision procedures.Furthermore, it highlights the necessity for a system that facilitates the sharing of medical records across healthcare institutions, especially when obtaining information directly from the patient or their guardians proves challenging.The authors discuss this case in conjunction with a literature review to stress the importance of proper information acquisition and advocate for enhanced mechanisms for medical record sharing.
