Orthopedic surgeons' knowledge regarding risk of radiation exposition: a survey analysis

Enhancing Radiation Safety Culture: Investigating the Mediating Role of Awareness Among Orthopedic Doctors and Operation Theatre Assistants

INTRODUCTION

The increasing use of minimally invasive orthopedic procedures has led to a greater reliance on fluoroscopy, resulting in elevated radiation exposure for surgeons. This study aimed to evaluate the knowledge, awareness, and daily practices of orthopedic surgeons regarding radiation safety in an academic hospital. Understanding radiation safety is crucial to minimize patient exposure and prevent adverse effects on surgeons.

METHODS

This cross-sectional study was conducted at the Department of Orthopedics of different tertiary care hospitals in Rawalpindi, Pakistan. Data were collected prospectively for two years, and a total of 505 participants, including residents, consultants, and operation theatre assistants, completed a questionnaire. The questionnaire was validated by experts and covered information on fluoroscopy usage, frequency of surgeries, awareness of radiation safety, and protective measures. Ethical approval was obtained, and data were analyzed using SPSS version 26.0.

RESULTS

The majority of participants were male (74.1%), and the sample included various ranks of orthopedic surgeons. Only 56.2% of participants were aware of the usage of fluoroscopy, and 40.2% had read some research on the topic. While 44.6% used lead aprons for radiation protection, the usage of other protective measures and dosimeters was limited. The mediation analysis showed an insignificant indirect association between the rank of orthopedic surgeons, number of surgeries performed, and fluoroscopy usage as a mediator. Awareness and reading research on fluoroscopy were significantly associated with radiation protection.

CONCLUSION

The knowledge, awareness, and daily practices of orthopedic surgeons regarding radiation safety in fluoroscopy use need improvement. The findings emphasize the importance of implementing training programs, providing radiation protection devices, and ensuring compliance with safety guidelines.

Use of a novel imageless navigation system reduced fluoroscopy exposure and improved acetabular positioning in anterior approach total hip arthroplasty: a case-control study

INTRODUCTION

Direct anterior approach (DAA) for total hip arthroplasty (THA) frequently utilizes fluoroscopy. The purpose of this study is to assess the impact of using a novel, imageless THA navigation system on radiation exposure and acetabular cup placement consistency.

MATERIALS AND METHODS

This was a retrospective, single-surgeon cohort study of a consecutive group of patients who underwent DAA THA for osteoarthritis. An optic-based imageless navigation system was used to determine intraoperative acetabular inclination and anteversion angles referenced off of a generic coronal and sagittal plane in 71 cases (study group). These were compared with 71 manual cases (control group) for fluoroscopy exposure, operative duration, and acetabular placement variation. Cohorts were similar in their distributions of sex, race, ethnicity, and body mass index. Comparisons between groups were made using independent samples t tests. Alpha error was 0.05.

RESULTS

Study patients experienced significantly less fluoroscopy exposure time {3.59 [Standard Deviation (SD) 1.95] vs. 9.15 (SD 5.98) seconds; p < 0.001} and dosage (0.30 [SD 0.23] vs. 0.78 [SD 0.63] mGy; p < 0.001). Study and control patients had similar operative times [82.69 (SD 11.70) vs. 89.54 (SD 14.60) minutes; p = 0.09]. The study group had a significantly lower radiographic variation for inclination and anteversion, based on mean proximity to the centroid of each cohort [3.55 (SD 1.88) vs. 5.39 (SD 3.51); p < 0.001] and also a greater proportion of cases that fell within 1 SD of the mean cohort inclination and anteversion (40.8% vs. 21.1%; p = 0.009).

CONCLUSIONS

Use of a novel imageless navigation system for DAA THA significantly reduced fluoroscopic radiation exposure and improved consistency in acetabular cup placement.

Prevalence and Spectrum of Occupational Injury Among Orthopaedic Surgeons: A Cross-Sectional Study

Orthopaedic surgeons are at increased risk for many occupational hazards, both physical and mental. The aim of this study was to evaluate a wide range of work-related injuries among orthopaedic surgeons in the United States.

Methods

An electronic survey was developed to assess both physical and mental occupational hazards among orthopaedic surgeons. Descriptive statistics were analyzed for all survey items and compared using chi-square and paired t tests, as appropriate.

Results

The 1,645 responding orthopaedic surgeons (7% response rate) reported a total of 2,702 work-related musculoskeletal injuries, 17.9% of which required surgical treatment. Of the 61 who filed a disability claim, only 66% returned to work and 34% retired early. Additionally, 17.4% of respondents reported having been diagnosed with cancer since starting practice, and 93.8% reported experiencing a finger stick at some point in their career. Over one-half (55.8%) had experienced feelings of psychological distress since beginning practice, and nearly two-thirds (64.4%) reported burnout from work.

Conclusions

This study captured a spectrum of occupational injuries that pose longitudinal risks to an orthopaedic surgeon's physical and mental well-being. Our hope is that this analysis of occupational hazards will help to raise awareness among the orthopaedic and medical communities and lead to efforts to reduce these risks.

Knowledge and practice of radiation protection in the operating theater among orthopedic surgeons

Purpose

Many orthopedic procedures, particularly minimally invasive surgeries that require fluoroscopic imaging, present a radiation exposure risk to the orthopedic surgeon. Surgeons may have a higher risk of developing cancer if they receive significant amounts of radiation. Using personal protective equipment (PPE) and appropriate imaging device positioning, plays an important role in reducing the surgeon's radiation exposure. However, there is a lack of knowledge about the surgeon's radiation safety awareness and practices. Therefore, the aim of this study is to investigate the practices and radiation protection knowledge of orthopedic surgeons in the operating theater.

Approach

A nationwide survey was conducted from October 2021 to January 2022 to evaluate the radiation protection practices and awareness of orthopedic surgeons in Jordan. Normalized practice and knowledge scores were evaluated through the survey and compared between different groups. Descriptive statistics were used to present the surgeon's practices and radiation protection knowledge. Student's t -test was used to compare the outcomes between surgeons that received radiation protection training and surgeons who did not. Using ANOVA analysis, we compared the score outcomes for all the other variables.

Results

The surgeons that received radiation protection training had significantly higher practice score 39.6% compared with 31% for the group that did not have training ( p = 0.01 ). No statistically significant difference in the knowledge scores was found between the two groups. Although 91% of the surgeons reported using some kind of PPE, only 5.5% used a dosimeter badge during surgeries.

Conclusion

There is an obvious deficit in radiation safety training of orthopedic surgeons.

X23D-Intraoperative 3D Lumbar Spine Shape Reconstruction Based on Sparse Multi-View X-ray Data

Visual assessment based on intraoperative 2D X-rays remains the predominant aid for intraoperative decision-making, surgical guidance, and error prevention. However, correctly assessing the 3D shape of complex anatomies, such as the spine, based on planar fluoroscopic images remains a challenge even for experienced surgeons. This work proposes a novel deep learning-based method to intraoperatively estimate the 3D shape of patients' lumbar vertebrae directly from sparse, multi-view X-ray data. High-quality and accurate 3D reconstructions were achieved with a learned multi-view stereo machine approach capable of incorporating the X-ray calibration parameters in the neural network. This strategy allowed a priori knowledge of the spinal shape to be acquired while preserving patient specificity and achieving a higher accuracy compared to the state of the art. Our method was trained and evaluated on 17,420 fluoroscopy images that were digitally reconstructed from the public CTSpine1K dataset. As evaluated by unseen data, we achieved an 88% average F1 score and a 71% surface score. Furthermore, by utilizing the calibration parameters of the input X-rays, our method outperformed a counterpart method in the state of the art by 22% in terms of surface score. This increase in accuracy opens new possibilities for surgical navigation and intraoperative decision-making solely based on intraoperative data, especially in surgical applications where the acquisition of 3D image data is not part of the standard clinical workflow.

Are Indian orthopaedic surgeons aware of the health hazards of radiation exposure? A survey and review on awareness and ways to mitigate them

BACKGROUND

Standardized education on the short and long-term health hazards of radiation and thus the awareness regarding current radiation exposure limits is restricted in the field of orthopaedics. There is a lack of awareness regarding the risks related to radiation exposure amongst orthopaedic surgeons and therefore the recommended safety precautions to assess and mitigate these potential risks should be emphasized. Orthopaedic surgeons should adopt the ALARA (as low as reasonably achievable) principle. All precautions should be taken to keep all members of the operation room safe from radiation exposure and safeguard patients too.

METHODS

The survey questionnaire developed in consult with senior orthopaedic surgeons and radiation protection officer consisting of 27 questions was conducted among the orthopaedic surgeons and resident doctors.

RESULTS

15% responders were unaware about risks of radiation exposure in routine orthopaedic surgery and 82% unaware of the recommended yearly allowance per individual. 30% responders were unaware of correct positioning of the C-arm and 44% were unaware regarding the same distance to be maintained from the C-arm to reduce radiation exposure. 27% responders were unaware regarding pulsed fluoroscopy and its benefits. 45% responders were unsure regarding the thickness of the lead apron. 83% never use a thyroid gland shield and none of the responders use leaded eye glasses. Only 11% responders use lead badges for documentation of radiation exposure.

CONCLUSION

Orthopaedic surgeons should understand the basics and basis of radiation exposure limits, be familiar with this literature on the incidence of tumors, dermatitis, cancer risk and cataracts and understand the current intraoperative fluoroscopy safety recommendations. The damaging effects to human tissue caused by radiation exposure are documented since the first reports regarding use of radiographs, hence emphasis on radiation safety and protection should be universally incorporated into graduate medical education.

Occupational Hazards to the Joint Replacement Surgeon: Radiation Exposure

BACKGROUND

Intraoperative fluoroscopy is an essential tool to assist orthopedic surgeons in accurately and safely implanting hardware. In arthroplasty cases, its use is on the rise with the increasing popularity of the direct anterior (DA) approach for THA. However, exposure of ionizing radiation poses a potential health risk to surgeons. While the benefits of intraoperative fluoroscopy in DA THA is becoming clearer, and are well-described in the literature, the potential health dangers associated with career-long cumulative radiation exposure are rarely discussed.

METHODS

In this article, we review the available literature to discuss radiation safety in orthopedics with a focus on total joint arthroplasty. We present the basic science of radiation, discuss the amount of radiation exposure in orthopedic surgery, and review the potential health risks associated with long-term exposure.

CONCLUSION

Overall, the radiation dose exposure to arthroplasty surgeons is low and within recommendations for occupation exposure limits. However, due to the stochastic health impacts of ionizing radiation, there is no threshold dose below which radiation exposure is truly safe. Therefore, it is imperative that surgeons practice proper fluoroscopy safety habits, such as wearing proper protective equipment, minimizing fluoroscopy time and magnification, and maximizing distance from the radiation source to minimize the life-long cumulative radiation exposure and associated health risks.

Ultrasound-guided distal minimally invasive metatarsal osteotomies (US-DMMO): A cadaveric study about its safety and accuracy

BACKGROUND

Distal minimally invasive metatarsal osteotomies have become increasingly popular. This technique requires fluoroscopic control, but recently, an ultrasound-guided procedure has been described. The aim of this anatomical study was to assess the quality safety of ultrasound-guided minimally invasive metatarsal osteotomies.

METHODS

Ultrasound-guided distal minimally invasive metatarsal osteotomies were performed in 9 cadaveric pieces. The location of the osteotomy, its angulation, and the adjacent anatomical structures injuries was evaluated RESULTS: Thirty-six osteotomies were performed. The osteotomy was metaphyseal in 97.2% of the cases, the average angulation was 47.67° (±4.49, 40-59°) and the average distance to the articular cartilage was 3.22 mm (±1.27, 1-7 mm). One osteotomy (2.8%) was intraarticular and there was one joint capsule lesion (2.8%). The failure, the extreme point distance and angulation values, and the joint capsule injury correspond to a fifth metatarsal.

CONCLUSIONS

The ultrasound-guided technique is safe and allows a correct location and angulation of the osteotomies.

Radiation Protection Capability of Operating Room Personnel: Development and Psychometric Properties of a Questionnaire

Background:

Radiation protection is an important principle in some wards of the hospital such as radiology, catheterization laboratory and operating room. Due to the increasing use of radiation in the operating room, there is a need to design an accurate and appropriate tool to evaluate the radiation protection capability of operating room personnel.

Objective:

This study aims to test the psychometric properties of a questionnaire on radiation protection capability.

Material and Methods:

This cross-sectional study was conducted in two stages. The first stage was designing items based on the review of available literature, and the second stage was measuring the validity and reliability of the questionnaire using face validity and content validity Content Validity Index (CVI) and Content Validity Ratio (CVR). Then the questionnaire was filled out by 200 operating room nurses to evaluate the construct validity by Principal Component Analysis method. Reliability of the questionnaire was evaluated by test–retest and Cronbach’s alpha analysis method.

Results:

Due to the results, test–retest correlation coefficient was 0.912, and Cronbach’s alpha coefficient was 0.824, indicating a desirable internal consistency.

Conclusion:

This study introduces a valid and reliable questionnaire for evaluating the radiation protection capability of operating room nurses.

A Preliminary Survey of Women Orthopaedic Surgeons on Awareness of Radiation Safety Practice and Breast Cancer Risk in India

OBJECTIVES

To assess women surgeons' awareness of radiation protection protocols, cumulative dose, safety measures, radiation exposure, and breast cancer risk in India.

METHODS

The data were acquired through a survey monkey questionnaire circulated to women orthopaedic surgeons across the country through the WOICE group, e-mails and phone. The questionnaire assessed the respondents' awareness of radiation protection measures and level of exposure. Medical history on breast cancer during their professional life, time of diagnosis, and radiation exposure were collected. Data were analysed and expressed as percentages.

RESULTS

Fifty-one women orthopaedic surgeons responded. These were sub-grouped into early and late-career group based on whether they had worked in orthopaedics for less than 10 years (n = 33) or 10 or more years (n = 18). The mean number of years of practice of the respondents was 8.1 years, and for the group with 10 or more years was 18.7 years. 90.2% reported compliance to the lead shield, while 9.8% (n = 5) were non-compliant because of the shield's weight. Of the included respondents, 88.8% are currently working. Among all the respondents, only 13.7% (n = 7) use a radiation dosimeter. Not surprisingly, 88.2% (n = 45) of all respondents were unaware of the total radiation exposure received. Two surgeons in the more than 10-year practice category reported a history of breast carcinoma.

CONCLUSIONS

This preliminary report suggested a need for more awareness of radiation protection measures among women orthopaedic surgeons. Hence, along with the practice of wearing a lead gown, use of lightweight shield, awareness on exposure measure and use of radiation dosimeter should be encouraged.

Radiation in orthopaedics (RIO) study: a national survey of UK orthopaedic surgeons

OBJECTIVES

Orthopaedic surgeons have a responsibility to minimise risks of ionising radiation to patients, themselves and staff. This study aims to establish the understanding of radiation practice, legislation and risk by orthopaedic surgeons.

METHODS

A nationwide online survey of UK-based orthopaedic surgeons was conducted. Participants answered 18 multiple-choice questions assessing level of radiation safety training, basic principles/knowledge of ionising radiation, relevant legislation and operating practice.

RESULTS

A total of 406 surgeons completed the survey. 92% reported using intraoperative ionising radiation at least once per week. 38% received no formal training on radiation safety. Knowledge of basic principles of radiation and legislation was limited. There was variable knowledge when labelling an image intensifier machine and choosing its safest orientation. Poor uptake of radiation protection equipment was noted. Only 19% agreed they had adequate training in ionising radiation safety and 27% reported receiving adequate training in equipment emitting ionising radiation in the operating theatre.

CONCLUSION

Many orthopaedic surgeons in the UK do not believe they are adequately trained in radiation safety. There is a deficiency amongst practicing surgeons in basic knowledge, relevant legislation and practicalities of the use of ionising radiation in the operating room. This could potentially put patients and health-care professionals at additional risk. We recommend that a standardised national training programme on the basic principles and safety of ionising radiation is implemented for all practicing orthopaedic surgeons.

ADVANCES IN KNOWLEDGE

This paper is the first UK national survey amongst orthopaedic surgeons and is one of the largest reported internationally.

The use of ionising radiation in orthopaedic surgery: principles, regulations and managing risk to surgeons and patients

The use of ionising radiation for plain film radiography and computerised tomography is fundamental in both diagnostics and treatment for orthopaedics. However, radiation is not without risk as high exposure can increase the risk of cancer. Little time is spent educating doctors about the relative risks of radiation, both to patients and themselves. In addition, there are common misunderstandings about the best ways to mitigate such risk. We aim to provide an overview of the fundamental principles of the use of ionising radiation and its risks within the context of orthopaedic surgery. While providing a narrative review of the current literature, we discuss the basic physics, standards of good practice and relevant UK and European regulations. We discuss the risks to patients and surgeons and suggest ways that these can be mitigated in the operating theatre. A thorough understanding of the risks, and appropriate procedural rules, with respect to the use of ionising radiation is essential for those in orthopaedic practice.

A survey analysis of knowledge levels of urologists about radiation safety and fluoroscopy use

AIMS

To evaluate the awareness of the use of fluoroscopy in endourological procedures, as well as the theoretical and practical applications of preventive measures.

MATERIAL AND METHOD

Between May 2018 and April 2019, a 26-question survey prepared using Google Docs was sent to urologists via email. Personal information, radiation training and behaviours related to radiation and fluoroscopy usage, and the use of protective equipment were queried.

RESULTS

A total of 226 participants fully completed and returned the email survey. Of the 226 participants, 78 (34.5%) were academics, 44 (19.4%) were residents while 104 (46.1%) were experts. More than 60% of the participants stated that they participated in the operation requiring less than five fluoroscopy use per week. The majority of operations requiring fluoroscopy consisted of endourological procedures. The lead apron was used by 93% of the participants, but the use of protective glasses and gloves was very low (3.5%). The majority of academicians, experts and residents did not use dosimeters (76.9%, 82.7% and 81.8%, respectively). More than 50% of the participants did not have literature information about the harmful effects of radiation with the use of fluoroscopy. The most common complaints on the day of fluoroscopy were fatigue and headache.

CONCLUSION

The lack of information regarding the radiation protection measures and harmful effects of radiation is common among urologists in Turkey. Therefore, systematic training programs on fluoroscopy use and radiation exposure should be provided during urology residency.

Typical air kerma area product values for trauma orthopaedic surgical procedures

BACKGROUND

The aim of study was to establish the typical radiation quantity values for the most common trauma orthopaedic surgical procedures and to compare them with reference values of equivalent procedures performed in other institutions. In addition, we assess the impact of image intensifier and flat panel detector technology used for fluoroscopically guidance on patient exposure.

MATERIALS AND METHODS

Five most frequently performed fluoroscopically guided trauma orthopaedic procedures in University Medical Centre Ljubljana were analysed. Data on 199 cases over a 6 months period from December 2016 to June 2017 were gathered retrospectively. Study covered 40 dynamic hip screw fixations (DHS), 23 proximal femoral nail insertions (PFN), 20 proximal humeral nail insertions (PHN), 77 partial hip endoprosthesis implantations (PEP) and 39 percutaneous posterior spine fixations (PPS). The median and average along with the first and third quartile values of air kerma area product (KAP) for each procedure type were calculated as well as median and average value of fluoroscopy screening time.

RESULTS

Typical KAP value for dynamic hip screw fixation was set at 0.52 Gycm2; for proximal femoral nail insertion at 0.53 Gycm2 and for proximal humeral nail insertion at 0.26 Gycm2. For implantation of partial endoprosthesis typical KAP value utilizing flat panel technology was set at 0.08 Gycm2 and at 0.21 Gycm2 when the image intensifier technology was used. Typical KAP value for percutaneous posterior spine fixation was set at 1.26 Gycm2, using flat panel technology and at 3.98 Gycm2 using image intensifier technology.

CONCLUSIONS

Established typical KAP levels of surgical orthopaedic procedures in traumatology will serve as a valuable tool for further radiation exposure optimization.

Tips, quips and pearls: Ultrasound-guided distal metatarsal minimal invasive osteotomy (US-DMMO)

Metatarsalgia is a frequent cause of forefoot pain. Surgical treatment is based on the performance of osteotomies at the level of the minor radii to restore a normal distribution of pressure within the forefoot and improve the biomechanics during gait. In recent years, percutaneous surgery of the foot, and specifically distal metatarsal minimal invasive osteotomy, have proven to be a valid technique, providing satisfactory clinical results, similar to open osteotomy with less soft tissue aggression, but it requires intraoperative fluoroscopy to be performed. This article will present a modification to guide the procedure by ultrasound providing a new option that eliminates radiation and provides greater portability and accessibility.

Radiation exposure and fluoroscopically-guided interventional procedures among orthopedic surgeons in South Korea

Background

The use of fluoroscopically-guided interventional (FGI) procedures by orthopedic surgeons has been increasing. This study aimed to investigate the occupational radiation exposure among orthopedic surgeons in South Korea.

Methods

A nationwide survey of orthopedic surgeons was conducted in South Korea in October 2017. The dosimetry data of the participants were obtained from the National Dosimetry Registry. The orthopedic surgeons were categorized by job specialty [spine or trauma specialists, other orthopedic specialists, and residents], and descriptive statistics for the demographics and work-related characteristics were presented. Multivariable logistic regression analysis was used to evaluate the risk factors for the orthopedic surgeons who were not linked with the dosimetry data.

Results

Among the total participants (n = 513), 40.5% of the orthopedic surgeons spent more than 50% of their time working with the FGI procedures when compared with their overall work. The average frequency of the FGI procedures among the orthopedic surgeons was 12.3 days per month. Less than 30% of the participants were regularly provided with radiation monitoring badges. The proportion of subjects who always wore lead aprons and thyroid shields were 52 and 29%, respectively. The residents group experienced more unfavorable working conditions of radiation exposure than the other specialists. The dosimetry data were not significantly linked among the residents (odds ratio [OR] 2.10, 95% confidence interval [CI] 1.11–3.95) and orthopedic surgeons working at small hospitals (OR 4.76, 95% CI 1.05–21.51).

Conclusions

Although orthopedic surgeons often performed FGI procedures, they wore protective gear less frequently, and a large proportion of orthopedic surgeons were not monitored by the national radiation dosimetry system. As the number of radiation procedures performed by the orthopedic surgeons increases, more intensive approaches are needed to reduce radiation exposure, especially for spine and trauma surgeons.

The hidden risk of ionizing radiation in the operating room: a survey among 258 orthopaedic surgeons in Brazil

Background

This study aims to assess orthopaedic surgeon knowledge in Brazil about ionizing radiation and its health implications on surgical teams and patients.

Methods

A 15-question survey on theoretical and practical concepts of ionizing radiation was administered during the 23rd Brazilian Orthopaedic Trauma Association annual meeting. The survey addressed issues within orthopedic surgery, such as radiation safety concepts, protection, exposure, as well as the participant gender. Participants were either orthopedic surgeons or orthopedic surgery residents working at institutions in Brazil.

Results

One thousand surveys were distributed at the moment of the meeting registration, and 258 were answered completely (25.8% response rate). Only 5.8% of participants used basic radiation protection equipment; 47.3% used a dosimeter; 2.7% reached the annual maximum permissible radiation dose; 10.5% knew the period of increased risk to fetal gestation; 5.8% knew the maximum permissible radiation dose during pregnancy; 58.5% knew that the hands, eyes, and thyroid are the most exposed areas and at greater risk of radiation-related lesions; 25.2% knew the safe distance from a radiation-emitting tube is 3 m or more; 44.2% knew the safest positioning of the radiation-emitting tube; 25.2% knew that smaller tubes emit greater radiation at the entrance dose to magnify the image; and 55.4% knew that the surgery team receives more scattered radiation in surgical procedures performed on obese patients.

Conclusion

This study revealed inadequate theoretical and practical knowledge about radiation exposure among orthopaedic surgeons in Brazil. Only a minority of orthopaedic surgeons used basic radiation protection equipment. No significant differences in knowledge were found when comparing all orthopedic surgery specialties. Our findings indicate an urgent need for education to increase knowledge among orthopaedic surgeons about the hazards of ionizing radiation. Personal protection and implementation of the ALARA (as low as reasonably achievable) protocol in daily practice are important behaviors to prevent the harmful effects of ionizing radiation.

The knowledge, awareness and practices of radiation safety amongst orthopaedic surgeons

Background

Fluoroscopic imaging in orthopaedic theatres is increasing, with added risk to the orthopaedic surgeon who is increasingly being exposed to ionising radiation. It is thus crucial for orthopaedic surgeons to have a working knowledge of radiation safety. In spite of these concerns, however, many orthopaedic surgeons do not receive standard training in radiation safety.

Objectives

The evaluation of orthopaedic surgeons' knowledge, awareness and everyday practices regarding radiation safety in an academic hospital.

Methods

A questionnaire with multiple-choice-type questions was developed by a panel of experts and used to conduct a descriptive study. The questionnaire had multiple dimensions, each evaluating orthopaedic knowledge, awareness and practices, respectively. The study population included orthopaedic surgeons rotating within the orthopaedic circuit of the University of Pretoria.

Results

Orthopaedic surgeons regularly make use of fluoroscopic imaging in theatre, with 34 (77%) participants indicating that they use fluoroscopy in more than half of all their procedures performed. Most participants have insufficient knowledge of radiation safety, with the majority failing to correctly answer basic questions on radiation safety. Forty (91%) participants do not wear personal dosimeters, in spite of 39 participants (89%) believing that they are vulnerable to adverse effects. Basic radiation protection devices are underutilised, with 32 (73%) participants indicating that they have not received adequate training in radiation safety.

Conclusion

The majority of orthopaedic surgeons regularly use fluoroscopic imaging in theatre yet lack in-depth knowledge and awareness regarding radiation safety associated with this imaging modality. Implementation of a radiation safety training programme is thus recommended.

Radiation Exposure in Orthopaedics

» The damaging effects to human tissue caused by radiation exposure have been documented since the first reports regarding use of radiographs in the late nineteenth century. » Orthopaedic surgeons and residents often are undereducated about the risks associated with radiation exposure and the recommended safety precautions to help mitigate these potential risks. » Orthopaedic surgeons need to adopt the ALARA (as low as reasonably achievable) principle: whenever possible, all available precautions should be taken to keep all members of the operating room safe from radiation exposure while emphasizing the best appropriate care for patients. » An emphasis on radiation safety and protection should be universally incorporated into graduate medical education.

Behaviour and knowledge skill levels of orthopedic surgeons about radiation safety and fluoroscopy use: A survey analysis

OBJECTIVE

The aim of this study was to evaluate the behaviour and knowledge skill levels of Turkish orthopedic surgeons about fluoroscopy usage and radiation safety.

METHODS

The questionnaire, consisting of nineteen questions, was sent to orthopaedic surgeons and requested by a total of 323 surgeons online. The questions were about personal information, training and behaviours related to radiation and fluoroscopy usage, and the use of protective equipment.

RESULTS

A total of 277 individuals completed the questionnaire. The answers of 180 surgeons whose working duration was more than 1 year and also who participated in at least one fluoroscopy requiring operation per week, were analysed. 22 (12%) participants answered that they were trained on fluoroscopy usage. Sixty people (33.3%) reported that they did not use any protective equipment regularly. The most commonly used protection methods were lead aprons 123 (68.3%). Thyroid protectors were used by 92 participants (52.1%). There was no significant difference between the groups when comparing the use of protective equipment according to the academic title. Only 19 (10.6%) of the surgeons noted that they used dosimeter regularly, and 15 (83.3%) of them reported that they controlled their dosimeters.

CONCLUSION

In this study, Orthopedic surgeons were found not to be adequately trained about use and risks of fluoroscopy and also not to be equipped about methods for preventing radiation damage.

Radiation safety: a focus on lead aprons and thyroid shields in interventional pain management

C-arm fluoroscopy is useful equipment in interventional pain management because it helps to guide correct needle targeting for the accurate injection and drug delivery. However, due to increased use of C-arm fluoroscopy in various pain procedures, the risk of radiation exposure is a significant concern for pain physicians. The harmful biological effects of ionizing radiation on the human body are well known. It is therefore necessary to strive to reduce radiation exposure. Lead aprons with thyroid shields are the most fundamental radiation protective devices for interventional procedures, and are very effective. However, the operator's radiation safety cannot be guaranteed because pain physicians seem to lack sufficient interest, knowledge, and awareness about radiation safety. Also, inappropriate care and use of radiation protective devices may result in a higher risk of radiation exposure. The purpose of this article was to review the literature on radiation safety with a focus on lead aprons and thyroid shields and present recommendations related to those devices during C-arm fluoroscopic-guided interventions by pain physicians.
