“…18 Despite their limitations, film badges have been employed successfully in the majority of contemporary studies in this field and remain the 'gold standard for personal radiation monitoring in hospitals'. 17 No consistent exposure level was detected with the radiographers' film badges which concurs with work by Alonso et al 18 who showed that for hip fracture fixation, the scattered dose outside a 2-m zone is less than 1 µSv. Although they question the necessity of personal lead protection outside this area, they do recommend that lead aprons and thyroid shields be worn by surgeon and assistants.…”

“…6,7 The range of operative procedures requiring image intensifier screening has led to an interest by orthopaedic surgeons in their exposure to ionising radiation. [8][9][10][11] Studies have considered exposure during experimental operation set-ups on phantom patients, 12 during common trauma operations, [13][14][15] for different locations and personnel in the operating theatre, [16][17][18] for different parts of the body, 19 and also investigating methods to reduce exposure. 20,21 There is evidence, however, that actual practice of basic ionising radiation protection varies widely.…”

INTRODUCTION We monitored image intensifier use by orthopaedic trainees to assess their exposure to ionising radiation and to investigate the influence of sub-specialty training.MATERIALS AND METHODS Five different orthopaedic registrars recorded their monthly image intensifier screening times and exposure doses for all cases (trauma and elective), for a combined total of 12 non-consecutive months. Radiation exposure was monitored using shoulder and waist film badges worn both by surgeons and radiographers screening their cases.RESULTS Registrars in spinal sub-specialties were exposed to significantly higher doses per case and cumulative doses per month than non-spinal trainees (P < 0.05), but significantly lower screening times per case (P < 0.05). There were no significant differences in cumulative screening times per month (P > 0.05). Regression analysis for all surgeons showed a significant relationship between shoulder film badge reading and cumulative dose exposed per month (P < 0.05), but not for cumulative screening time. Shoulder film badge recordings were significantly higher for spinal compared with non-spinal registrars (P < 0.05), although all badges were below the level for radiation reporting. Only one radiographer badge recorded a dose above threshold.CONCLUSIONS Whilst the long-term effects of sub-reporting doses of radiation are not fully understood, we consider that this study demonstrates that trainees should not be complacent in accepting inadequate radiation protection. The higher doses encountered with spinal imaging means that sub-specialty trainees should be alerted to the risk of their increased exposure. The principle of minimising radiation exposure must be maintained by all trainees at all times.

Background: Image intensifiers have become popular due to the concept of minimally invasive surgeries leading to decreasing invasiveness, decreased operative time, and less morbidity. The drawback, however, is an increased risk of radiation exposure to surgeon, patient and theatre staff. These exposures have been of concern due to their potential ability to produce biological effects. The present study was embarked upon to analyse the amount of radiation received by orthopedic surgeons in India using standard precautionary measures and also to bring awareness about the use of image intensifier safety in everyday practice.

“…During fluoroscopy, the surgeon is exposed to either primary or scatter radiation due to the necessary proximity to the fluoroscope. The assistant surgeon, nurses, and anaesthetists are better protected against radiation from the fluoroscope because they can distance themselves from the fluoroscope when it radiates, thus the exposure is reduced to nearly immeasurable values; but also due to staff rotations, such that the assistant surgeons and nurses do not assist all of the PAO procedures, their exposures are limited [2,14,17,18].…”

The objective of this study was to directly measure the radiation exposure to the orthopaedic surgeon and to measure dose points to the surgeon's fingers, thyroid gland, and forehead during intraoperative fluoroscopy in periacetabular osteotomy (PAO). In a series of 23 consecutive periacetabular osteotomy procedures, exposure monitoring was carried out using thermo luminescent dosimeters. The effective dose received by the operating surgeon was 0.008 mSv per operation which adds up to a yearly dose of 0.64 mSv from PAO. The median point equivalent dose (mSv) exposure under PAO was 0.009 for the forehead and thyroid gland, 0.045 for the right index finger, and 0.039 for the left index finger. The effective estimated yearly dose received by the operating surgeon was very low. Wearing a lead collar reduces radiation exposure to the thyroid gland while the lead gloves did not protect the surgeon's fingers.
