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).

목적: 상완골 근위부의 해부학적 재형성을 위한 다양한 형태의 제3세대 견관절 치환술이 시행되고 있지만 한국인을 대상으로 한 상완골 근위부 구조에 대한 연구는 미미하다. 이에 저자들은 한국인의 상완골 근위부의 구조적 분석 결과에 대해 보고하고자 한다. 대상 및 방법: 2009년 1월부터 2011년 10월까지 명지병원에 내원하여 컴퓨터단층촬영을 시행한 100개의 상완골을 대상으로 하였고, 평균연령은 48세(17-83세)였다. 컴퓨터단층촬영 영상을 토대로 상완골 두 관절면의 직경, 상완골 저고, 상완골 곡률반경, 상완골 경사각, 상완골 두와 대결절 사이 거리, 결절 사이 고랑과 상완골 간부 사이의 각, 상완골 외측부각, 내측 오프셋, 후측 오프셋의 총 9가지 항목을 측정하고, 연령별, 성별로 분류하여 비교 분석하였다. 결과: 상완골 두 관절면의 직경은 42.70±3.57도 (이하 평균수치), 상완골 두 저고는 14.30±2.0 mm, 상완골 두 곡률반경은 22.50±1.97 mm였으며 세 개 항목에 있어 성별로 유의한 차이를 보였다. 상완골 경사각은 130.00±4.28도, 상완골 두와 대결절 사이는 7.50±0.99 mm, 결절 사이 고랑과 상완골 간부 사이의 각은 6.60±0.92도, 상완골 외측부각은 163.40±4.05도, 내측 오프셋은 5.20±2.10 mm, 후측 오프셋은 3.10±1.80 mm를 나타냈다. 결론: 한국인의 상완골 근위부의 해부학적인 구조에 대한 연구 결과가 한국인에 적합한 견관절 치환물을 디자인하는 데 도움이 되고, 임상에 적용하여 보다 정확한 해부학적 재형성이 가능하리라 생각한다. 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.

Arterialized venous flaps are used clinically, but are to date still limited in their application to small surface areas with predominantly axial vessel patterns. Partial necrosis of the larger arterialized venous flaps remains an unsolved problem. In search for means to increase their survival and reliability, this study was designed to investigate the effects of various delay procedures and delayed periods on the survival of arterialized venous flaps made on the rabbit ears. The first study was subdivided into 3groups : non-delay group, limited-delay group, extensive delay group. All 10 arterialized venous flaps in the 'non-delay' group underwent total necrosis. In the 'limited-delay' group, 7 of 10 flaps survived following arterialization sustaining, however an approximately 32.1% full thickness necrosis was checked. In comparision, 8 flaps of the 'extensive-delay' group survived with 94.1% viable surface area. The second study was subdivided into 5 group : non-delay, 4, 7, 14 and 21 days delay groups. 10 arterialized venous flaps in the non-delay group underwent total necrosis. The mean survival area of 4 dags delay group was 17% with survival area around the anterior marginal vein. The result of 7days delay group was 60% survival area with necrotic area in the posterior portion of ears. In the 14 days delay group, the mean survival area was 94.1% as nearly the same as the result of 21days delay group with 95% survival area. From this study we can conclude the followings ; 1) surgical delay procedures increase the chances of survival of arterialized venous flaps 2) the more extensive the delay, the larger the survival area and 3) 14 days was most appropriate surgical delay period to gain maximal effect of flap survival.
