The occupational exposure to methylmethacrylate (MMA) vapor during percutan
eous vertebroplasty was determined. During five vertebroplasty procedures,
air-sampling pumps were attached to medical personnel, MMA vapor levels in
the samples were then quantified using gas chromatography, The samples coll
ected yielded MMA vapor levels of less than five parts per million (ppm), T
he MMA vapor concentrations measured were well below the recommended maximu
m exposure of 100 ppm over the course of an 8-hour workday.
