Fatal pulmonary fat embolism during total hip replacement due to high-pressure cementing techniques in an osteoporotic femur.

High-pressure cementing techniques, involving the use of a cement gun and cement restrictor, placed within the femoral medullary cavity, are commonly used to secure the femoral component of hip arthroplasties. Such techniques have been shown to be important in maintaining the integrity of the bone-cement interface and also the integrity of the cement itself. This case report illustrates that such techniques are not without complications.
