Intravenous polymethyl methacrylate after cemented hemiarthroplasty of thehip

Current cementing techniques used during hip arthroplasty aim to maximize t he bond at the bone-cement interface in an effort to increase the longevity of the prosthesis. To accomplish this, one must generate high intramedulla ry pressures, which are known to be associated with complications such as L cement implantation syndrome. We record a rare complication following ceme nt pressurization of a hip hemiarthroplasty that resulted in intravenous po lymethyl methacrylate (PMMA). This complication however, is not associated with a significant morbidity or mortality, but it is important to identify and distinguish from a femoral cortical defect, which can be created during surgery.
