Title: The utility and value of portable ultrasound for injured athletes in the acute trauma setting at international elite Taekwondo competitions

Dae Hyoun Jeong

Dr. Jeong is the new chairperson of World Taekwondo medical and anti-doping committee who introduced the use of point-of-care ultrasound to World Taekwondo for the first time. He has an extensive background in the use of point of care ultrasound in primary care, sports medicine, emergency & critical care medicine. He is certified in diagnostic musculoskeletal (RMSK) and abdomen(RDMS) sonography as well as EM POCUS (APCA). He has written three book chapters on this subject and has developed curriculum in this area for international Taekwondo team doctors, attending physicians, fellows, resident physicians, and medical students. He has been invited as an instructor for nationally well-known ultrasound workshop programs at UC Irvine Annual Ultrafest and National Center for Procedures Institute Ultrasound workshop for primary care physicians.


Statement of the Problem:  Physicians volunteering for sporting events may face with many acute traumas and musculoskeletal injuries at sporting events. At many times, on-site imaging modality such as x-ray, CT or MRI is not available which leads to unnecessary transferring athletes to other facility just for imaging studies due to uncertainty of diagnosis. Also, it is often difficult to obtain imaging studies for the injured due to availability or cost especially at international competition events.  Recently, much smaller and cheaper portable ultrasound machines with better image quality has been available so many clinicians has been utilizing portable ultrasound in their practice for point-of-care clinical decision making. However, there is very few research on using this modality at sporting events.
Methodology & Theoretical Orientation: Since 2017 Muju World Taekwondo Championships in June 2017, World Taekwondo (WT) medical and anti-doping committee has been adopted point-of-care ultrasound (POCUS) project using portable ultrasound machines for acutely injured athletes in Taekwondo competitions at WT promoted events.
Findings: Injury surveillance using portable ultrasound results revealed that there were more fracture and high-grade ligament tear cases in upper compared to previously published epidemiology studies on Taekwondo competition-related injuries. Also, there were some findings requiring urgent referral such as traumatic vitreous detachment, comminuted nasal fracture, pneumothorax, comminuted tibial shaft fracture and acute DVT of peroneal vein. The on-site POCUS in competition enabled venue clinicians to make more accurate diagnosis which resulted in the decease of the number of unnecessary hospital transfer by 35% and detect serious injuries in timely manner. 
Conclusion and Significance:  The use of Portable ultrasound is very useful and valuable in acute trauma setting at sporting events to make faster and more accurate diagnosis which may improve the on-site management of acute sports-related injuries.
