Occupational orthopedic problems and its relation to personal radiation protection in interventional radiology

Purpose: Several studies report occupational orthopedic problems among interventional cardiologists. These health problems are usually multifactorial. However, the personal protective equipment used should play a major role. An online survey was conducted to determine the frequency of such health problems among interventional radiologists and to correlate them with the use of personal radiation protective clothing. Material and Methods: An anonymous online survey that comprised of 17 questions was sent via e-mail to 1427 members of the German Society for Interventional Radiology (DeGIR) in Germany, Austria and Switzerland. The questions were focused on interventional workload, the use of personal radiation protection apparel and orthopedic problems. Given the different scale levels, the associations between the variables were analyzed using different statistical methods. A significance level of p < 0.05 was chosen. Results: There were 221 survey responders (15.5 % response rate). About half of responders (47.7 %) suffered from more than five episodes of orthopedic problems during their interventional career. Lumbar spine was involved in 81.7 % of these cases, cervical spine in 32.8 %, shoulder in 28.5 % and knee in 24.7 %. Because of orthopedic problems, 16.1 % of the responders had to reduce and 2.7 % had to stop their interventional practice. The number of affected body regions correlates with the fit of the radiation protection means (p < 0.05, r = 0.135) and the reduction of activity as an interventional radiologist (p < 0.05, r = -0.148). Conclusion: Overall, the survey reveals widespread orthopedic problems at several body regions among interventional radiologists, associated with the fit of radiation protection systems, among other factors. A connection between the orthopaedic complaints and the radiation protection system used could not be established.
