Purpose: A traumatic lung cyst (TLC) is a rare complication and is usually detected with a pulmonary contusion. This study attempted to identify the prognostic factors and the clinical characteristics for pulmonary contusion with TLCs. Methods: We retrospectively reviewed the medical records and chest CT findings of 71 TLC patients who visited our hospital from January 2006 to December 2007. Patients were assessed for any clinical characteristics. We evaluated significant differences between the survival and the death groups for patients with a traumatic lung cyst. Results: The male-to-female ratio of patients with TLCs was 54:17, and the mean age of the patients was $37.70{\pm}19.78years$ with 36.6% of the patients being under 30 years fo age. The cause of blunt thoracic trauma was mainly pedestrian traffic accidents (26.8%) and falls (25.4%). Associated conditions included pulmonary contusion in 68 patients (95.7%), hemopneumothorax in 63 patients (88.7%), and rib fracture in 52 patitents (73.2%). There was no consistent relationship between the number of TLCs and the pulmonary contusion score. The overall mortality rate of TLC patients was 26.8%. Death correlated with a need for ventilatory assistance, mean arterial pressure, worst mean arterial pressure in 24 hours, initial pH and base excess, worst pH and base excess in 24 hours, refractory shock, initial GCS score, and pulmonary contusion score. Conclusion: The presence of the aforementioned predictors indicate serious injury, which is the main determinant of the outcome for thoracic injuries with TLCs.

Purpose: Injuries are the most important cause of morbidity and mortality in the childhood population worldwide. Thus, this study was down to investigate the type and the severity of injuries according to the age group in childhood. Methods: A survey of injury information and a chart review were done on 378 children (257 boys, 121 girls) who visited the Emergency Departments of Asan Medical Center from March 1, 2009, to March 31, 2009. To determine differences in injury mechanism, accident place, injury site, New Injury Severity Score (NISS) and Pediatric Trauma Score (PTS), we divided the 378 patients into 4 group: under 1 year, 1 to 4 years, 5 to 9 years, and 10 to 15 years. Results: The mean (${\pm}SD$) age of the study group was 5.1 (${\pm}4.4$) years. Two year olds formed the largest group of injured children, with 77 cases (20.4% of the total). The most common cause of injury in childhood was being hit by an object (26.2%). Falls were frequent in the under-1-year group (22.2%) and slip downs (30.1%) were more frequent in 1-to-4-year group. More than half (53.4%) of the injuries occurred in the home, and the most common places of home-related injuries were the living room (41.1%) and the bedroom (31.2%). The mean (${\pm}SD$) NISS was 1.5 (${\pm}1.8$), and traffic accidents had the highest NISS ($2.8{\pm}5.1$). Injuries occurred most frequently during the evening. The peak period was 4:00 PM to 8:00 PM (33.7%). Conclusion: Patterns of childhood injury by age group were considerably different, and less severe and nonhospitalized injuries were common. Thus, need to improve surveillance of a variety of injuries, promote intersectional collaboration, build institutional capacities and mobilize community support and policy as an investment in prevention.

We reviewed the charts and photos taken during arthroscpy of 218 knees of 214 patients(240 menisci) retrospectively. The male was 156 cases(73%) and the female 58 cases(27%). The mean age of the patients was 35 years(range, 7-68). The patients who had definite trauma history were classified as trauma group(Group 1), and the patients who had no or could not recall trauma history were as atrauma group(Group 2). The trauma group was subclassified into the the patients with sports injury, traffic accident, fall down, slip down, direct injury, and miscellaneous according to the causes of the trauma. The patterns of meniscal tear were classified into longitudinal, bucket-handle, horizontal, transverse, flap, complex, and degenerative tear on the basis of O'Connor's classification. The aim of this study was to compare the meniscal tear patterns between trauma group(Group 1) and atrauma group(Group 2) and between the patients before and after the age of 40. The results were as follows ; 1) The difference in the incidence of tear between medial and lateral meniscus was not significant statistically. 2) In Group 1, 60% of the cases showed the longitudinal and bucket-handle tear and 52% of the cases of Group 2 were horizontal tear. 3) In the patients before the age of 40, the longitudinal and bucket-handle tear were 52% of the cases and in the patients over 40, tear patterns which were thought to be related to degenerative change, horizontal and degenerative tear were more than half of the cases (51%).

Objectives The purpose of this study is to investigate traffic accident patients who were admitted to Korean and Western medicine hospital. Methods According to the medicine record from Dong-eui university, 908 traffic accident patients who were admitted to Korean medicine hospital and Western medicine hospital from 1st January 2011 to 31th July 2016 were analyzed. We classified the patients' sex, age, classification of diseases, hospitalization. Results 1. According to age and sex, the rate of male was 35.4%, and that of female was 64.6% in Korean medicine hospital. However, the rate of male was 46.6%, and that of female was 53.4% in Western medicine hospital. 2. According to admission procedures, the most patients (93.3%) went through out-patient department in Korean medicine hospital and 53.5% of patients went through emergency room in Western medicine hospital. 3. According to principal diagnosis, 'sprain and strain of neck level' was 65.4 percentage Korean medicine hospital and 'intracranial injury' was 63.2 percentage in Western medicine hospital. 4. There was no statistical significant in hospitalization periods between male and female in Korean medicine hospital. However, hospitalization periods of female were longer than that of male in Western medicine hospital. 5. There was no correlation between age and hospitalization period in both Korean and Western medicine hospital. 6. Average hospitalization period of Korean medicine hospital patients were shorter than that of Western medicine hospital patients. 7. According to automobile insurance review organization, hospitalization periods were not significantly different in both Korean and Western medicine hospital. Conclusions It is concluded that there is difference of characteristics between inpatients who were admitted to Korean and Western medicine hospital due to traffic accident.

Purpose: Missing cervical pathology after injury may lead to disability and influence long-term survival. Controversies continue to evolve concerning the initial screening methods used to predict cervical spine injury. Through a retrospective chart review, we attempted to analyze and propose factors predictive of cervical trauma. Methods: Of all the patients who had visited the Emergency Department of Korea University, from January 2009 to December 2009, a retrospective review of the clinical records of the 217 patients who had undergone cervical spine computed tomography was done. We investigated whether we could predict the need for cervical spine computed tomography shortly after presentation in trauma patients by comparing the group with fractures and group without fractures and by finding risk factors showing significant differences between the two groups that might be used as guides in decision making. Results: Of the 217 subjects who underwent cervical spine computed tomography scans, 33 were identified with fractures of the cervical spine while 184 were not. The most common mechanisms of trauma, in order, for those with fractures were falls, followed by traffic accidents. We found that the injury severity score, multiple injuries, a high-energy injury mechanism, neurologic deficit, and pain and tenderness of the cervical spine showed statistically significant differences between the two groups. Conclusion: Fractures of the cervical spine that are not observed with simple radiography occur with a relatively high frequency in trauma patients. Consideration should be given to the risk factors for cervical spine fracture, and if pertinent, cervical spine computed tomography should be performed with speed for early diagnosis of cervical spine fractures.

Purpose: To evaluate the effectiveness of intraoperative stress test for diagnosis of occult Lisfranc injury. Materials and Methods: Between April 2009 and October 2012, 21 patients with occult Lisfranc injuries underwent intraoperative stress test and internal fixation. There were 11 males and 10 females with an average age of 45.3 years (range, 23~79 years). Injuries were caused by traffic accident in 10 cases, indirect force (twisting injury) in 8 cases, and crush in 2 cases, falling from a height in 1 case. Unstable injuries on stress radiograph in occult injury of Lisfranc joint were treated by open reduction or closed reduction and fixation with cannulated screw or K-wire. Radiological evaluation was assessed according to preoperative and postoperative diastasis between $1^{st}$ and $2^{nd}$ metatarsal base. Results: Assoicated injuries were 9 cases of metatarsal fractures, 6 cases of cuneiform fractures and 6 cases of both metatarsal and cuneiform fractures. Medial and middle column fixation was in 13 cases, and three columns fixation was in 8 cases. Initial diastasis between $1^{st}$ and $2^{nd}$ metatarsal base was 2.8 mm (1.3~4.7 mm) on AP radiograph and postoperative diastasis between $1^{st}$ and $2^{nd}$ metatarsal base was 1.2 mm (0.5~2.4 mm) on AP radiograph. Conclusion: Even there is no sign of clear Lisfranc injury, it is necessary to pay attention and give evaluation on circumstances of occult Lisfranc injuries with metatarsal or cuneiform fractures. Intraoperative stress test is helpful to diagnose an occult Lisfranc injury. For unstable injuries on stress radiographs of occult Lisfranc joint injury, operative treatment with open or closed reduction and internal fixation is useful method.

Background After the laws regulating emergency medicine were amended in 2012, regional trauma centers were established in South Korea. Plastic surgeons specialize in the simultaneous surgical care of patients with facial trauma, burns, and complicated wounds. The objective of this study was to evaluate the role of the plastic surgery department in treating severe trauma patients. Methods From January 2012 to December 2018, we enrolled 366 severe trauma patients with an Injury Severity Score (ISS) over 15 who received treatment by specialists in the plastic surgery department. Of these patients, 298 (81.4%) were male, and their mean age was 51.35 years (range, 6-91 years). The average ISS was 22.01 points (range, 16-75 points). Results The most common diagnosis was facial trauma (95.1%), and facial bone fracture (65.9%) was most common injury within this subgroup. Patients were referred to 1.8 departments on average, with the neurosurgery department accounting for a high proportion of collaborations (37.0%). The most common cause of trauma was traffic accidents (62.3%), and the average length of stay in the general ward and intensive care unit was 36.90 and 8.01 days, respectively. Most patients were discharged home (62.0%) without additional transfer or readmission. Conclusions Through this study, we scoped out the role of the specialty of plastic surgery in the multidisciplinary team at regional trauma centers. These results may have implications for trauma system planning.

Today, with the development of modern civilization, the change of industrial structure and the increase of traffic volume and population make the number of maxillofacial injury patients also increase. Especially, the fracture possibilities of mandibular condyle have been increased because of mandibular position and shape. I experienced the case that mandibular condyle fracture caused by gun-shot injury(Bullet had been packed at the opposite condyle of input site) was treated by foreign body removal and condyle open reduction. I will represent that case with the journal review.
