| Popis: | The difficulty of removing intramedullary methylmethacrylate (MM) in revision of hip prostheses is considerable. To facilitate its removal from bone, Nd:YAG laser energy was delivered to a bovine anatomic specimen of the femur with the medullary canal filled with MM. Through an endoscope the laser was observed to soften and ablate the methyl methacrylate. The vapors generated by this process were analyzed by mass spectrometry. The two chief components were hydrogen and carbon monoxide, followed by carbon dioxide, methane, acetylene, and C3 unsaturated hydrocarbons. A high capacity smoke evacuator must be used in conjunction with laser vaporization of methylmethacrylate. The method should be evaluated under in vivo conditions in dogs before it is attempted in patients. |
