Traumatic spinal cord infarction is a rare condition that causes serious paralysis. The regulation of spinal cord blood flow in injured spinal cords remains unknown. Spinal cord infarction or ischemia has been reported after cardiovascular interventions, scoliosis correction, or profound hypotension. In this case, a 52-year-old man revisited the emergency center with motor and sensory abnormalities in all four extremities 56 hours after a motor vehicle collision. Despite the clinical presentation and imaging examination, there were no specific findings on the patient's first visit to the trauma center. Cervical spine computed tomography angiography showed a narrow vertebral artery, and diffusion-weighted imaging revealed spinal cord infarction from C3 to C5 with high signal intensity. It should be kept in mind that delayed-onset spinal cord infarction may occur in minor or major trauma patients as a result of head and neck injuries.

Horse riding is widely recognized as a valuable form of education, exercise and therapy. But, the injuries observed in horse riding range from very minor injuries to fatalities. In order to reduce these injuries, the effective horseback riding simulator is required. In this paper, we proposed the implementation method of horse gait and riding aids for horseback riding robot simulator HRB-1. For implementation of horse gait to robot simulator, we gathered and modified real motion data of horse. We obtained two main frequencies of each gait by frequency analysis, and then simple sinusoidal functions are acquired by genetic algorithm. In addition, we developed riding aids system including hands, leg, and seat aids. With the help of a developed robotic system, beginners can learn the skill of real horse riding without the risk of injury.

Whiplash injuries in low-speed rear-end collisions are the most common injuries and has been a social issue in insurance industry, such as excessive medical claim costs along with exaggerated injuries of victims and treatments from hospitals. According to the Korea Insurance Development Institute reports, the number of claims by rear-end collision was approximately 703,000, which accounts for 53.6 % of the total car-to-car collisions in 2014. Part of the neck injury claims in the Korea car insurance was approximately 28.3 %. Furthermore, approximately 98.4% of the injured persons in rear-end collisions sustained minor injuries under AIS2. In order to improve this situation as well as find out the severity of neck injuries from rear-end collision, the Korea Automobile Insurance Repair Research and Training Center conducted car-to-car rear-end crash tests that striking vehicles(SUV) collided into different sizes of struck-vehicles(small, middle, and large sedan) at the impact speeds of 8 km/h ~ 16 km/h. In order to analyze the whiplash injury, the BioRID-II was seated in each struck-vehicles, and the neck injury criteria(NIC), head contact time, maximum vehicle accelerations, and mean vehicle accelerations were calculated from values from the accelerations of the dummy and the struck-vehicles.

Pseudoaneurysm of the anterior tibial artery is a rare cause of pain and swelling of the lower leg and the foot following minor sports injuries. When there is no definite musculoskeletal cause of pain, it is important to consider pseudoaneurysm. Early diagnosis and management are essential for the successful outcome. MRI and angiogram are useful for early diagnosis. We report a case of pseudoaneurysm of the anterior tibial artery following minor sports injury. The patient experienced complete relief of the symptoms after resection of the pseudoaneurysm.

Objectives : Chronic post-thoracotomy pain is a refractory condition that responds poorly to existing pain treatments. The aim of this report is to describe favorable symptom changes in a patient with chronic post-thoracotomy pain after major chest trauma who received a series of manual acupuncture treatments over 3 months. Methods : Twelve sessions of manual acupuncture were provided to the patient, once or twice a week. Results : The manual acupuncture sessions were well tolerated. Minor adverse events, including temporary minor bleeding at the needled sites, were intermittently observed. The patient's symptoms, including pain, sleep disturbance, and anxiety gradually resolved and had almost completely disappeared after 12 sessions of acupuncture treatment. Conclusion : This single case report cannot confirm whether the observed positive changes in the patient's symptoms and dysfunctions are associated with the acupuncture treatments. Randomized controlled trials are necessary to explore the role of acupuncture in chronic post-thoracotomy pain in patients with major chest trauma.

Purpose: To know about the clinical characteristics such as causes, types, associated injuries and treatment of the lateral meniscus injuries. Materials and Methods: Retrospective analysis was performed for 129 lateral meniscus tears which were divided into 2 groups, Non-discoid and Discoid. Analysis included age and sex distribution, causes of injury, types and location of tear, associated injuries, and methods of treatment. Results: Both Non-discoid and Discoid were prevalent in man and Discoid group was equally distributed through 2nd to 5th decades and Non-discoid group was more prevalent in 4th to 5th decades. Sports injury was the most common cause in both groups and the Nondiscoid group tended to sustain minor injuries compared to Discoid group. Complex tear and body was most common type and site of tear in both groups. Associated injuries were common in Non-discoid group and isolated injuries were common in Discoid group. Partial meniscectomy was commonly done in Non-discoid group and subtotal meniscectomy in Discoid group based on the types of tear. Conclusion: Non-discoid and Discoid lateral meniscus injuries are similar in types and sites of injuries but different in causes of injury, associated injuries and methods of treatment. Therefore, proper diagnosis and treatment would be necessary according to the characteristics.

Purpose: Little information has been published regarding minor burn injuries in infants, most of which are preventable. To fill this research gap, this study explored the patterns and mechanisms of burn injuries in infants to ascertain whether such incidents can be prevented. Methods: This was a retrospective study, based on data collected prospectively from all infants (<12 months old) admitted to our hospital with burns in the four-year period between January 1, 2015 and December 31, 2018. A medical record review provided basic demographic information, such as age at the time of injury, sex, cause of injury, duration of treatment, operative treatment, and the extent and type of burn, as well as the anatomical region involved. Results: Fifty-seven infants were diagnosed with burn injuries, with scalding being the most common type (47%), followed by contact (32%) and steam (14%). Seven infants of eight steam burn patients injured by pressure cooker. Superficial second degree was the most common depth of injury (72%) followed by first degree (17%) and deep second degree (8%). Average age per injury type was calculated by independent T-test. Average ages of patients with contact and steam burns were significantly lower (7.06 months; P=0.19) and higher (9.25 months; P=0.005), respectively, than for other burn types. Conclusion: Given that infants cannot control their body movements, talk, or manage by themselves, they are entirely dependent on the proper care of adults. Consequently, in addition to the prevention of burns, special care should be taken for the pressure cooker.

Purpose: This study aims to determine the effect of proprioceptive neuromuscular facilitation (PNF) pectoralis minor stretching and lower trapezius strengthening exercise on posture change, shoulder range of motion (ROM), and pain in rotator cuff repair patients with a rounded shoulder posture (RSP). Methods: Following baseline measurements, the subjects (n = 25) with rotator cuff repair were randomized into two groups: the PNF group (n = 13), which engaged in PNF pectoralis minor stretching and lower trapezius strengthening exercise, and the control group (n = 12), which received traditional physical therapy. Each group participated in the intervention five times per week for two weeks. The RSP values for the postural changes, flexion and abduction ROM, and visual analogue scales (VASs) of both groups were recorded at both pre- and post-intervention. In addition, before and after the intervention, a paired t-test was conducted to compare the within-group changes and an independent t-test to compare the between-group differences. Results: After the two-week intervention, both groups experienced significantly decreased RSP and VAS values (p < 0.05) and a significantly increased ROM (p < 0.05). Meanwhile, the PNF group showed greater improvements in RSP, ROM, and VAS than the control group (p < 0.05). Conclusion: These results suggest that PNF pectoralis minor stretching and lower trapezius strengthening exercise reduce posture and shoulder pain and enhance ROM in rotator cuff repair patients with RSP.

The main causes of traffic accidents can be classified by 3 factors - human error, vehicle deficiency and road environmental problem and most accidents occurs not only 1 factor but combination of 2 or 3-factors. Among these factors, road environmental factor is the most important factor due to influence the behavior of cars and road users and road environmental factor affects 30% of total accidents approximately. The 5 years traffic accidents data analyzed to verify the accidents severity on Korea National Highways. In order to analyze the severity, Ordered Probit Model was used. As a independent variables of this model the number of lane, neighbor road environments, sight distance, vertical grade, lane width, shoulder width and traffic volume were used and as a dependent variables the minor injuries, serious injuries and fatalities were used. Research results shows that sight distance and lane width are identified as significant factors for the traffic accident severity and lesser sight distance and lane width shows greater traffic accident severity.

Laparoscopic cholecystectomy, though an uncommon surgical procedure in paediatric age group is still associated with a higher risk of post-operative bile duct injuries when compared with the open procedure. Small leaks from extra hepatic biliary apparatus usually lead to the formation of a localized sub-hepatic bile collection, also known as biloma. Such leaks are rare complication after laparoscopic cholecystectomy, especially in paediatric age group. Minor bile leaks can usually be managed non-surgically by percutaneous drainage combined with endoscopic retrograde cholangio-pancreatography (ERCP). However, surgical exploration is required in cases not responding to non-operative management. If not managed on time, such injuries can lead to severe hepatic damage. We describe a case of an eight-year-old girl who presented with biloma formation after laparoscopic cholecystectomy who was managed by ERCP.
