  • The car seat head restraint is used for neck injury(whiplash injury) prevention in rear end impacts. The purpose of this study was to evaluate the seat head restraints for the total number of 34 domestic cars. H-POINT machine and HRMD(head restraint measuring device) were applied to measure backset(the distance between head and seat head restraint) and height(height gap between head and seat head restraint). For tendency study of driver's head position, we took the 320 driver's pictures in the street. As results, There were only five percent drivers in good and acceptable zone. For car seat head restraint system, the results was 9 cars for good zone, 10 cars for acceptable zone, 9 cars for marginal zone and 6 cars for poor zone were evaluated. For a precise evaluation the of whiplash injury, detailed FE neck model will be developed and the clinical database should be constructed for model validation.

  • 소아에 있어서 수부손상의 대부분은 가정이나 외부로부터의 위험인자에 대한 자기방어능력이 부족한데서 발생되는데, 핵가족화로 인해 자녀에 대한 부모의 관심이 줄어들면서 그 빈도가 더욱 증가되고 있는 추세이다. 본 영남대학교 의과대학 성형외과학교실에서는 1983년 6월부터 1991년 10월까지 수부손상으로 재건술을 받은 10세이하의 소아를 대상으로 조사를 시행하여, 주로 봄, 가을에 활동력이 주어지기 시작하는 2세-4세의 남아에서 수지 첨부와 zone II에 많이 발생하고, 문틈에 끼여서 손상을 입는 경우가 많았으며, 전충피부이식이나 복합조직이식에서 좋은 결과가 나타남을 알 수 있었다.

  • We retrospectively evaluated our results of replantations of distal digital amputations and analyzed the factors deterrent to the survival of replanted digits. From January 2004 to 2005 June, we performed 101 cases of replantations following complete amputations at or distal to interphalangeal joint level. The study included 98 patients with a mean age of 35.6 years (range 1 to 63 years). Amputation level correlated to zone I (distal to the lunula)in 47 cases and zone II (lunula to distal interphalangeal joint) in 54 cases according to Yamano's classification. According to the mechanism of amputation, 24 cases (22.9%) suffered from guillotine type injury, 27 cases (27.1 %) from avulsion type injury and 50 cases (50%) from crush type injury. In all cases, a single arterial anastomosis was performed. Venous anastomosis on either volar or dorsal side was performed in 12 cases of amputation in zone II. Salvage procedure for venous drainage was performed in 98 cases. The mean duration of salvage procedures was 5.9 days (ranging from 4 to 14 days). Successful replantation was achieved in 96 cases (95.1%), which included 93.7% cases in zone I amputations and 96.3% cases in zone II amputations. A single venous anastomosis was performed in 12 cases of amputation in zone II. All of them survived completely. Among the 5 cases that failed to survive, 3 cases were related with avulsion injury in zone I. Initial mechanism of injury determines the survival rate of amputated parts as it is directly related with the status of vessels and soft tissues. Meticulous precaution during the salvage procedure may affect the overall survival rate of distal digital replantations.

  • Penetrated injury of common carotid artery (CCA) is rare and extremely lethal. Carotid artery injury tends to bleed actively and potentially occlude the trachea. It can cause fatal neurological complications. An accurate diagnosis and adequate treatment are very needed to the successful outcome of the penetrating vascular injury in zone 1, 2, and 3 of the neck. Open surgical treatment is more invasive and complicated than endovascular treatment. We experienced a case with penetrating injury in neck zone 2. Here, we report the case successfully treated with endovascular stent graft technique.

  • Resuscitative endovascular balloon occlusion of the aorta (REBOA) has been increasingly used in recent years as a resuscitative adjunct for trauma patients with life-threatening non-compressible torso hemorrhage. By blocking the aorta temporarily with an inflated balloon, REBOA preserves cerebral and coronary perfusion while diminishing exsanguination below the balloon, thereby providing time for resuscitation and definitive bleeding control. When determining the occlusion zone during the REBOA procedure, factors such tortuosity of the aorta, co-occurring minor chest injuries, and the severity of shock must be considered, as well as the main injury site. This paper describes a case of high Zone I REBOA in an elderly patient with a tortuous aorta who had concomitant injuries of the chest and pelvis.

  • Purpose: Zone I fractures of the fifth metatarsal bone can generally be treated by conservative methods while both surgical and conservative methods are used for zone II fractures. However, the clinical results of conservative treatment have been rarely reported. The purpose of this study is to report the clinical results of conservative treatment for zone I and II nondisplaced fractures. Materials and Methods: Between July 2007 and August 2008, consecutive thirty seven patients (38 fractures) with zone I and II fractures of the fifth metatarsal bone were treated with tolerable weight bearing and minimum duration of immobilization based on pain on weight bearing. We evaluated the duration of immobilization, time to clinical and radiographic union, and time to pre-injury activity level. Results: Clinical and radiological union were achieved in all patients without any complications including malunion or nonunion. The mean duration of immobilization was 28.7 days. The mean 33.1 days and 48.9 days were required for clinical union and radiographic union respectively, after the initial injury. The mean time to pre-injury activity level was 4.8 months. Conclusion: Our study shows that the acute nondisplaced zone I, II fracture of fifth metatarsal bone can be treated effectively using tolerable weight bearing and minimum duration of immobilization, which is based on the pain on weight bearing.

  • Objective: To report the authors' experience in performing thoracic endovascular aortic repair (TEVAR) for zone 2 lesions after traumatic aortic injury (TAI). Materials and Methods: This retrospective review included 10 patients who underwent zone 2 TEVAR after identification of aortic isthmus injury by CT angiography (CTA) upon arrival at the emergency room of a regional trauma center from 2016 to 2019. Patients were classified into two groups: those who underwent left subclavian artery (LSA) embolization concurrently with the main TEVAR procedure, and those in whom LSA embolization was not performed during the main procedure, but was planned as a bailout treatment if type II endoleak was noted on follow-up CTA images. Pre-procedural and procedure-related factors and post-procedure prognosis were compared between the groups. Results: There were no differences in pre-procedural factors, occurrence of endoleaks, and post-procedure prognosis (including mortality) between patients in the two groups. The duration of the procedure was shorter in the non-LSA embolization group (61 minutes vs. 27 minutes, p = 0.012). During follow-up, type II endoleak did not occur in either group. Conclusion: Delaying preventative LSA embolization until stabilization of the patient would be desirable when performing zone 2 TEVAR for TAI, in the absence of endoleak on the completion aortography image taken after complete deployment of the stent graft.

  • 본 연구는 고속도로의 공사구간의 사고 심각도에 영향을 미치는 주요인들을 파악하고 사고 심각도와의 관계를 규명하는 것을 목적으로 한다. 2011년부터 2015년까지 국내 고속도로에서 발생한 교통사고 자료를 공사구간 사고와 일반구간(비공사구간) 사고로 구분하였으며, 이 중 물피사고를 제외하고 분석에 활용하였다. 의사결정나무(Decision Tree)기법을 적용하여 공사구간과 일반구간의 사고 심각도에 영향을 끼치는 요인들을 파악한 뒤 사고 특성 및 영향요인의 차이점을 비교하였다. 특히 공사구간에서는 교통량이 많고 중차량 비율이 높을 경우 전반적인 구간속도 저하로 사고 심각도가 낮아지는 반면, 교통량이 적고 중차량 비율이 낮을수록 구간속도가 증가하여 심각도가 높은 사고로 이어지는 경향을 확인할 수 있었다. 본 연구를 통해 도출한 공사구간 사고심각도 영향 요인들은 공사구간 안전 관리 대책 마련에 도움을 줄 수 있을 것으로 기대한다.

  • Background: Penetrating neck injuries are potentially dangerous and require emergency management because of the presence of vital structures in the neck. The risk of airway, vascular, neurological, and pharyngoesophageal injuries leads to many difficult diagnostic decisions. The purpose of this retrospective study is to evaluate our experience with management of penetrating neck injuries, and to assess treatment outcome. Material and Method: Forty-two consecutive patients were identified (26 patients from Korea university Ansan hospital, 16 patients from Guro hospital) as having penetrating neck injuries from 2003 to 2009. With review of medical records, variables were collected and evaluated including the location of injury, mechanism of injury, number of significant injuries, diagnostic modalities, duration of hospital stay and outcome. Results: The location of injury was zone I (lower neck) in 13 cases (31%), zone II (midportion of the neck) in 22 (52%), and zone III (upper neck) in 7 (17%). Injuries were caused by stab wounds in 23 patients, penetrating foreign bodies in 12. Among 35 patients who had deep injuries that violated the platysma, significant injuries, including major vascular (20), trachea (5) Pharyngoesophageal injuries (5) were identified in 24 patients. The mean hospital stay was 9.5 days. Conclusion: The penetrating trauma in the neck may show various degrees of severity. However, Cervical penetrating injury should not be underestimated in spite of the minimal width of the lesion.
