Radiation exposure of orthopaedic trainees: quantifying the risk.

Interest in radiation protection issues has recently grown within the medical profession. Several investigators have examined the radiation exposure of orthopaedic surgeons using X-rays during trauma surgery, and found that doses received are within acceptable limits. These studies however, have been performed over short time-periods or have been confined to single procedures only. In this paper, we report the results of monitoring of the total exposure across all procedures of a group of orthopaedic surgeons over a 4-month period. Doses received were all below the International Commission on Radiological Protection (ICRP) recommended limits. While these results are reassuring, they do not represent grounds for complacency. Continued vigilance will be essential as work practices continue to change. In orthopaedics, in contrast with other specialties, the limiting dose is that to the hands. In view of this finding, extremity dosimetry for surgeons regularly using X-rays in theatre should be considered.
