Description
The potential necrotizing effects of the heat produced by the exothermic polymerization process has raised questions regarding the use of polymethylmethacrylate (PMMA) in orthopedic surgery. An experimental model was used to: (1) analyze the amplitude and distribution of heat in bone taken from autopsy specimens when large metaphyseal defects (simulating tumor excision) were filled with curing PMMA and (2) to observe any significant necrotizing temperatures. The experimental design included two experimental groups of five distal femora into which either a small- or large-bore defect was made in the lateral epicondylar region. These defects were filled with either one or two packs of PMMA cement, and temperature probes were used to record temperature elevations at the cement core, the bone-cement interface, and the surrounding 1-,
