The mouth guard is a device with elasticity to be installed in the oral cavity. It has a function to reduce the trauma in the oral cavity and to protect the teeth and surrounding tissues from trauma. The purpose of mouth guard is to prevent trauma and concussion. It is mandatory to wear a mouthguard in sports where there is a lot of contact and the possibility of trauma or concussion in the mouth area is high. The mouse guard is divided into a stock type, a mouth formed type, and a custom made type according to the manufacturing method. The custom made type is made on the individual dentition model and has excellent retention because of its excellent fit. Also, the effect of trauma prevention is excellent. It is possible to design and adjust by the dentist and reduce the complaint the athlete has about the mouthguard. In this article, the process of making a dentist-customized mouthguard was described.

Purpose: Pediatric hand trauma is common and sometimes causes deformity or disability. The incidence and etiologies of hand trauma in children are different from those in adults. This study analyzed the characteristics of pediatric hand trauma cases and patients over a 15-year period. Methods: We conducted a retrospective medical record review of 3,432 children (2,265 boys, 1,167 girls, under 18 years of age) with hand injuries from January 2005 to December 2019. We evaluated the sex distribution and injury etiologies. Injuries were classified by type as burns, amputations, crushing injuries, lacerations, extensor and flexor tendon injuries, open and closed fractures, and nerve injuries. Results: Among the pediatric hand injury patients, males were predominant (1.94:1). Simple lacerations (58.4%) were the most common injury type, followed by fractures (22.8%). Lacerations and burns tended to be common in younger age groups, while tendon injuries, nerve injuries, and crushing injuries were more frequently encountered in older age groups. Conclusions: Hand trauma prevention strategies should be established considering the frequent trauma etiologies in specific age groups. An awareness of age-specific characteristics of pediatric hand trauma patients will be helpful to prevent hand trauma.

A 91-year-old female presented to Chonnam National University Hospital Regional Trauma Center with a lateral compression type III fracture of the pelvis. She was managed non-operatively for a week in the intensive care unit under close observation and had an emergency operation due to delayed onset of an acute obstructed direct inguinal hernia. Traumatic abdominal wall hernias are rare. However, trauma surgeons should always be aware of the possibility of such injuries because of their critical consequences.

Purpose: The aim of this study is to evaluate the transfer pattern of multiple trauma patients after acute phase management and to determine whether the time between the surgeon's decision and the actual transfer correlates with the patient's insurance type. Methods: Three hundred ninety-two(392) multiple trauma patients visited the emergency room from January 2011 to April 2013. Among the 143 patients who were admitted by a trauma surgeon, 47 were transferred to another hospital after acute phase management. The age, gender, trauma mechanism, Revised trauma score (RTS), Injury severity score (ISS), insurance type, length of ICU stay and hospital stay were analyzed through a retrospective chart review. Results: The mean age was 47.7 years, and traffic accident was the most common mechanism(26, 55.3%). The mean RTS and ISS were 6.93 and 22.7, respectively. Twenty-five patients(53%) were covered by National health insurance, and 20 patients(42.6%) were covered by automobile insurance. Patients were transferred to primary (4.3%), secondary(80.9%), tertiary(4.3%) and care(10.6%) hospitals. The mean time from transfer decision to actual transfer was significantly longer for patients who were covered by automobile insurance than it was for patients who were covered by national health insurance (p=0.038). Conclusion: An appropriate transfer system at the end of acute phase care is essential for managing trauma centers with limited staffing and facilities. In addition, the mean time from transfer decision to actual transfer seemed to be definitely related to the type of insurance covering the patient.

본 연구에서는 외상 유형(단순 외상과 복합 외상)에 따라 PTSD 증상의 심각도와 자기 및 타인개념에 차이가 있는지를 확인하고자 하였다. 총 166명의 대학생 및 대학원생들 중 단순 외상(n=31)과 복합 외상(n=30)으로 분류된 참여자들의 자료를 최종 분석에 포함하였다. 참여자들은 생활사건 체크리스트(LEC), 개정된 사건 충격 척도(IES-R)와 E-prime으로 제작된 정서 스트룹 과제를 수행하였다. 결과는 다음과 같다. 첫째, 단순 외상 집단보다 복합 외상 집단에서 더 높은 수준의 PTSD 증상이 나타났다. 둘째, 스트룹 과제에서 부정적인 자기개념을 반영하는 단어를 2초 제시한 조건에서 복합 외상 집단이 단순 외상 집단보다 반응시간이 더 길었다. 이러한 결과는 복합 외상 집단과 단순 외상 집단이 적어도 PTSD 증상 및 자기개념에 다른 특성을 가지고 있다는 것을 제안한다. 마지막으로, 본 연구의 의의와 한계점에 대해 논의하였다.

구강악안면 영역의 외상은 치아파절, 탈구, 골절, 연조직 손상을 일으킬 수 있으며, 뇌진탕의 원인이 되기도 한다. 미국과 일본에서는 contact sports 일부에서 마우스가드의 장착이 의무화되어 있으나, 현재 한국에서는 운동 시 마우스가드의 장착을 거의 볼 수 없는 실정이다. 마우스가드는 크게 ready-made type과 custom-made type으로 나눌 수 있다. Ready made type의 마우스가드에는 형태가 일정하고 조정이 곤란한 stock mouthguard와 다소 조정이 가능한 mouth formed mouthguard가 있다. Custommade type의 마우스가드는 적합성이 뛰어나며 정확한 교합, 하악위를 재현할 수 있다는 장점이 있다. 마우스가드는 입술과 구강연조직을 치아로부터 보호하고, 치아에 가해지는 충격을 분산시켜 파절이나 탈구가능성을 줄여준다. 또한, 악골의 골절과 변위를 방지하고 충격을 흡수한다. 성장기 아동의 경우 치아손상의 30% 정도가 스포츠나 레포츠에 의한 것이라는 보고가 있으며, 이 경우 치아나 잇몸은 물론 성장 중인 치조골에 악영향을 주게 된다. 이 때 외상처치는 어려우며, 그 예후 또한 불명확하다. 따라서 성장기 아동의 마우스가드 장착은 외상 예방차원에서 중요하다. 이에 저자는 단국대학교 치과병원에 내원한 환아에게 ERKODENT$^{(R)}$사의 ERKOFORM-RVE를 이용한 흡입성형 마우스가드(vacuum type mouthguard)를 적용한 임상경험을 보고하는 바이다.

Rupture of the esophagus after blunt trauma is a rare event. But any type of esophageal rupture has the high morbidity and mortality rate. In these situations, the sign and symptom of the esophageal rupture is subtle and nonspecific; therefore, the physicians are usually not suspicious. Delaying in diagnosis prevents proper treatment (surgical or non-surgical) before significant complications occurred. We report a case of a cervical esophageal perforation with primary repair and drainage after blunt trauma.

Purpose: Pelvic trauma is a serious skeletal injury with high mortality. Especially in cases of severe injury trauma, treatment outcomes depend on early diagnosis and intervention. We expect trauma surgeon to play an important role in the management of severe multiple trauma patients. Methods: A retrospective study was performed on pelvic trauma patients with hemodynamic instability between March 2005 and September 2009. We divided the time period into period I (March 2005~Feburary 2009) and period II (March 2009~September 2009). The trauma surgeon and team started to work from period II. Data were collected regarding demographic characteristics, mechanism of injury, type of pelvic fracture, ISS(injury severity score), treatment modality, transfusion requirement, time to definitive treatment, and mortality. Results: During period I, among 7 hemodynamically unstable patients, 4(57.1%) patients died. However during Period II, only one of 6(16.6%) patients died. The demographic data and injury scores showed no differences between the two time periods, but the time to definitive treatment was very short with trauma team intervention(14.4 hrs vs. 3.9 hrs). Also, the amount of transfusion was less(41.1 U vs. 13.9 U). With arterial embolization, early pelvic external fixation led to less transfusion and made patients more stable. Conclusion: This study demonstrated the importance of the trauma surgeon and the trauma team in cases of hemodynamically unstable pelvic trauma. Even with the same facility and resources, an active trauma team approach can increase the survival of severely injured multiple trauma patients.

A Monteggia fracture is a proximal ulnar fracture with proximal radioulnar ligamentous instability. While there is no precise definition, Monteggia-equivalent fractures are generally considered Monteggia fractures accompanied by radial head fractures. These are rare. In this study, we report a rare variation of a Bado type IV Monteggia-equivalent lesion (fracture of proximal ulnar shaft, proximal radial shaft, and radial head) and its management.
