title: Irradiation of the surgeon during pinning of femoral fractures.
abstract: The intensity of scattered radiation in both a forward and a backward direction from a portable fluoroscope during pinning of the neck of the femur was measured by experiments on a cadaver. The intensity decreased rapidly with increasing distance from the flare of the greater trochanter. Hazard to the surgeon's hands from scattered radiation can be greatly reduced by positioning the C-arm of the fluoroscope so that the x-ray beam is directed laterally.
