The use and availability of thyroid shields in orthopaedic theatres: a telephone questionnaire of English hospitals.

There are no published guidelines issued for the use of thyroid shields by either the Royal College of Radiologists or the British Orthopaedic Association. It has previously been demonstrated that a thyroid shield should be worn during fluoroscopic screening using a portable image intensifier. Scrub staff not wearing a thyroid shield are currently being exposed to ionising radiation on a regular basis, with potentially harmful effects. Of the 210 hospitals in England with orthopaedic departments, 179 were telephoned and the use and availability of thyroid shields was asked. The results demonstrated that 98 orthopaedic theatres had sufficient numbers of thyroid shields available. Of these 98 orthopaedic theatres, thyroid shields were routinely used in only 28 theatres during fluoroscopic screening on a regular basis. It is the authors' recommendation that thyroid shields should be worn during orthopaedic procedures involving the use of an image intensifier.
