The Epidemiology of Spectator Injury and Illness in the Korean Professional Baseball League: 2 Consecutive Seasons (2011-2012) at the Jamsil Stadium / 대한스포츠의학회지

The aim of this study was to verify the epidemiology of spectator injury and illness in the baseball stadium during the games and the role of the on-site physician in hospital referral of spectators. We retrospectively reviewed the 'Documents of the medical aids' from 2011 to 2012 at Jamsil stadium. We have provided medical consultation to spectators as on-site physicians since 2012. The incidence of spectator injury and illness was 0.009% (1.68 spectators/game). During the study period, a total 448 spectators visited the first aid station, of which 324 cases (72%) were injuries and 124 cases (28%) were illness. The most common cause of injury was direct foul ball attacks (58.6%). According to the location of injuries, upper extremity injuries were most common, however, severe injury cases that were immediately referred to the hospital by ambulance were more commonly facial and oral injuries (p=0.000). Severe injuries occurred more frequently in games on weekends than weekdays (p=0.000).Headache was the most common illness followed by gastrointestinal problems. Hospital referrals were more frequent in the 2012 season when we were designated on-site physicians, as compared to the 2011 season (p=0.035).

Structural Analysis of Proximal Humerus in Korean / 대한정형외과학회잡지

PURPOSE: Third generation shoulder arthroplasty is widely performed nowadays; however, few studies on the anatomy of the proximal humerus in the Korean population have been reported. The authors have attempted to review the anatomy of the proximal humerus. MATERIALS AND METHODS: The study sample consisted of 100 humeri of patients with a mean age of 48 years (range of 17 to 83 years) who underwent computed tomography imaging between January 2009 and October 2011 at Myongji Hospital. Diameter of the articular surface, head thickness, radius of curvature, head inclination, head to tuberosity height, bicipital groove-shaft angle, lateral angle, medial offset and posterior offset were analyzed. Results were compared depending on age and gender. RESULTS: Mean values of diameter of the articular surface was 42.70+/-3.57 mm, head thickness was 14.3+/-2.0 mm, and radius of curvature was 22.50+/-1.97 mm; these three variables showed significant sex differences. Head inclination was measured as 130.00+/-4.28 degrees, head to tuberosity height was 7.50+/-0.99 mm, bicipital groove-shaft angle was 6.60+/-0.92 degrees, and lateral angle was 163.40+/-4.05 degrees. Mean medial and posterior offset were 5.2+/-2.1 mm and 3.1+/-1.8 mm, respectively. CONCLUSION: Based on the results of this study, the measurement values of Korean humeri can be used in design of the arthroplasty prosthesis, and this will lead to more accurate anatomical reconstruction of the shoulder joint.
