Purpose: The objective of this study was to determine the effects of coronavirus disease 2019 (COVID-19) on the volume of trauma patients, the number of orthopedic trauma operations, and the severity of injuries. We also investigated the correlations between social distancing and these variables. Methods: This was a retrospective review of trauma patient cases at a single focused training center for trauma in Korea from January 2017 to April 2021. The COVID-19 group included patients treated from January 1 to April 30 in 2020 and 2021, and the control group included patients treated during the same months from 2017 to 2019. The volume of trauma patients according to the level of social distancing was evaluated among patients treated from August 2, 2020 to November 23, 2020. Results: The study included 3,032 patients who presented to the emergency department with traumatic injuries from January to April 2017 to 2021. The average number of patients was 646.7 and 546.0 in the control and COVID-19 groups, respectively. The percentage of patients injured in traffic accidents (TAs) decreased from 25.0% to 18.2% (P<0.0001). The proportions of in-car TAs and pedestrian TAs also decreased from 6.7% and 10.8% to 3.5% and 6.0%, respectively (P=0.0002 and P<0.0001). The percentage of bicycle TAs increased from 2.4% to 4.0% (P=0.0128). The proportion of patients with an Injury Severity Score above 15 and the mortality rate did not change significantly. As the level of social distancing increased, the number of trauma patients and the number of trauma injuries from TAs decreased. The number of orthopedic trauma operations also depended on the social distancing level. Conclusions: The number of trauma patients presenting to the emergency department decreased during the COVID-19 period. The volume of trauma patients and orthopedic trauma operations decreased as the social distance level increased.

Objectives: This study conducted a survey research to characterize traffic accident(TA) patients seeking Korean medicine treatment and to analyze the symptom improvement and satisfaction scores. Methods: A survey was conducted in 122 outpatients, who visited OO University Korean Hospital due to TA-associated symptoms from November, 2017 to May, 2018. The questionnaire included information on patient demographic characteristics, accident circumstance details, pain levels, reason for treatment selection, treatment methods, treatment purpose, symptom improvement and satisfaction. All statistical analyses were performed using Windows SPSS version 20.0 Results: The characteristics of traffic accident patients using Korean medical institution were usually accidents that occurred while driving slowly, and minor injuries like a sprain. The most important consideration in choosing Korean medical institution was its past experience. The biggest reason for switching treatment from Western medicine to Korean medicine was for diverse treatments. Satisfaction with Korean medicine was measured between very satisfaction and satisfaction. Patients showed the highest satisfaction with acupuncture, followed by pharmacopuncture and chuna manual therapy. Most treatments were measured between very satisfaction and satisfaction. After treatment, 95.90 percent of the patients said they would recommend Korean treatment. Conclusions: Although this study has limitations as research in survey format, we intended to analyze determining factors for the use of Korean medicine treatment through satisfaction, symptom improvement, and Numeric rating scale (NRS) change.

Background: The purpose of this study was to investigate electric moxibustion on patients with back pain caused by road traffic accidents. Methods: This was a retrospective study (n = 112) comparing treatment with Korean medicine combined with electric moxibustion (n = 56), and Korean medicine alone (n = 56). Patient gender, age, Numeric Rating Scale (NRS), Oswestry Disability Index (ODI) and EuroQol-5 Dimension (EQ-5D) was recorded for each group at the time of hospital admission. Mean NRS measured weekly, mean ODI and EQ-5D scores were measured 2 weeks post-treatment, and evaluated by paired sample t test. using the Statistical Program for Social Science v. 25.0 for Windows. An independent, two-sample t test was used to test for a significant difference in the decrement of NRS, ODI and increment EQ-5D scores between groups. Results: NRS scores decreased in both groups after 1 week of treatment (electric moxibustion, from $5.13{\pm}0.79$ to $3.86{\pm}0.67$; Korean medicine alone, from $5.18{\pm}0.92$ to $4.30{\pm}0.94$; both p < 0.001). There was a significantly greater reduction in NRS score in the electric moxibustion group ($1.27{\pm}0.59$) than in the Korean medicine alone group ($0.88{\pm}0.61$; p = 0.001). After 2 weeks of treatment, EQ-5D scores increased significantly in the moxibustion group ($0.19{\pm}0.12$) compared with the Korean medicine alone group ($0.13{\pm}0.20$; p = 0.043). After 2 weeks of treatment, NRS and ODI scores decreased in both groups. EQ-5D increased in both groups. Conclusion: We suggest that electric moxibustion treatment may be effective for reducing early-stage back pain in patients with road traffic accident injuries.

The incidence of spinal cord injury increase due to traffic accident, industrial accident and leisure sports. Spinal cord injury damages motor and sensory function below the injury level, also affects autonomic functions associated with voiding and defecation. Sexual dysfunction and psychosocial, vocational maladaptations are also some of the unwanted consequences of injury. The purpose of this study is look for means to prevent and to manage complications in spinal cord injury through investigation and analysis. The subjects of this study in spinal cord injured patients were admitted to the department of physical therapy, Kwangju christian Hospital, Nam Kwang Hospital, Chun Nam university Hospital and Cho Sun university Hospital, from April, 1, 1995 to March, 31, 1996. The results are as follows: 1. The subjects comprised 96 cases of spinal cord injury, ranging from 17 to 85(mean-40.8 yrs) and included 72 males and 24 females. Among these patients, 58 were cervical injury, 20 were thoracic injury and 18 were lumbar injury. 2. As for a major causative of spinal cord injury were traffic accident(59.4%), fall down (27.1 %), and motocycle(4.2%).. 3. The bladder control were taken by indwelling cathetar(41.7%), Crede maneuver(37.5%) and self voiding(16.7%). The bowel control were taken by all aid(61.5%), assitance(32.3%) and self defecation(6.2%). 4. Possible of sexual function were 35 cases (47.9%). 5. The device of transfer used wheel chair(69.8%) and bed(16.7%). 6. The patients with higher cord lesion got more serious pain than lower cord lesion. Also the patients with higher cord lesion got a serious spasticity. 7. The incidence of decubitus ulcer among 96 patients were in case 46(47.9%). The largest group of the pressure sore sites were sacral portion(82.0%), less than 1 month of onset occured a large numbers(50%). Incidence of pressure sore by spasticity occured many patients in case of mild or moderate. Incidence of pressure sore by pain occured many patients in case of severe pain.

With today's social and cultural personal interactions, greater leisure time and participation in sports activities, and growing traffic volume, the risk of physical trauma has increased markedly. This is a clinical and retrospective study of patients exposed to oral and maxillofacial trauma. We clinically observed 72 patients with trauma in the Department of Oral and Maxillofacial Surgery, Kyunghee University Dental Hospital, from June 2006 through November 2007. The following data was obtained: 1. The male:female ratio of patients having experienced physical trauma was 6.2:1, with most patients in their twenties. 2. Traffic accident (37.5%) was the most common cause of trauma. 3. The highest incidence of fracture occurred to the zygomatic arch(22.1%) among mid-facial fractures and angle(37.5%), symphysis(35.4%) in mandible fractures. 4. Open reduction (88.9%) was the most frequently used form of treatment. Closed reduction was performed on the remaining 11.1% of cases. 5. Teeth and alveolar bone damage occurred in 23.6% of all cases. 6. Other injuries that were related to mid-face fracture occurred in 27.8% of all cases. 7. Post-operative complications occurred in 31.9% of cases, and the highest complication was the nerve injury.

Objective : Among pediatric injury, brain injury is a leading cause of death and disability. To improve outcomes, many developed countries built neurotrauma databank (NTDB) system but there was not established nationwide coverage NTDB until 2009 and there have been few studies on pediatric traumatic head injury (THI) patients in Korea. Therefore, we analyzed epidemiology and outcome from the big data of pediatric THI. Methods : We collected data on pediatric patients from 23 university hospitals including 9 regional trauma centers from 2010 to 2014 and analyzed their clinical factors (sex, age, initial Glasgow coma scale, cause and mechanism of head injury, presence of surgery). Results : Among all the 2617 THI patients, total number of pediatric patients was 256. The average age of the subjects was 9.07 (standard deviation${\pm}6.3$) years old. The male-to female ratio was 1.87 to 1 and male dominance increases with age. The most common cause for trauma were falls and traffic accidents. Age (p=0.007), surgery (p<0.001), mechanism of trauma (p=0.016), subdural hemorrhage (SDH) (p<0.001), diffuse axonal injury (DAI) (p<0.001) were statistically significant associated with severe brain injury. Conclusion : Falls were the most common cause of trauma, and age, surgery, mechanism of trauma, SDH, DAI increased with injury severity. There is a critical need for effective fall and traffic accidents prevention strategies for children, and we should give attention to these predicting factors for more effective care.

With the increase of industrialization, leisures, sports activities and traffic, the risk of trauma has increased markedly. Midfacial bones are relatively common sites of trauma, and are difficult sites of correct reduction and reconstruction, because midface is composed of mostly thin cortical bone surrounding cavities filled with either air or fat with discrete areas of bony condensation. A clinical study on 208 patients with midfacial bone fracture who visited Sanggye Paik Hospital during 5 years($1990{\sim}1995$) was done by analyzing sex, age, cause, fracture site, treatment method, complication and involvement of other body part, etc. The results obtained were as follows : 1. The occurrence was more frequent in male than in female with ratio of 2.7 : 1 and most frequently in twenties. 2. Traffic accident was the most common cause of midface fractures. 3. Zygoma was the most frequently occurred site(50%) of midface fractures. 4. Simple fracture(75%) was more frequently occurred than compound fracture(25%). 5. As treatment method, open reduction(76.4%) was used more frequently than closed reduction(23.6%) 6. Generally, operations are done in 5 days after admission(59.1%), and intermaxillary fixation was done in 78.4% of cases. 7. Teeth and alveolar bone damages were occurred in 32.2% of cases. 8. Other injuries that were related to midface fracture occurred in 63.3% of cases. 9. Post-operative complications occurred in 9% of cases.
