Traumatic abdominal wall hernia is a rare presentation, most commonly reported in the context of motor vehicle accidents and associated with blunt abdominal injuries and handlebar injuries in the pediatric population. A 13-year-old boy presented with multiple traumatic injuries and hemodynamic instability after a high-speed motor vehicle accident. His injuries consisted of massive traumatic abdominal wall hernia (grade 4) with bowel injury and perforation, blunt aortic injury, a Chance fracture, hemopneumothorax, and a humeral shaft fracture. Initial surgical management included partial resection of the terminal ileum, sigmoid colon, and descending colon. Laparostomy was managed with negative pressure wound therapy. The patient underwent skin-only primary closure of the abdominal wall and required multiple returns to theatre for debridement, dressing changes, and repair of other injuries. Various surgical management options for abdominal wall closure were considered. In total, he underwent 36 procedures. The multiple injuries had competing management aims, which required close collaboration between specialist clinicians to form an individualized management plan. The severity and complexity of this injury was of a scale not previously experienced by many clinicians and benefited from intrahospital and interhospital specialist collaboration. The ideal aim of primary surgical repair was not possible in this case of a giant abdominal wall defect.

The more civilized, the more incidence had happened in our daily life, particularly in industrial factories, by traffic accident, and in sports, etc. in the dental field. The accidental trauma is usually involved the teeth and surronuding tissues. And the author intended to study of the traumatic injuries of anterior teeth by individual tooth, age, sex, cause of trauma, and how they were treated. The following results were obtained: 1. The patients with traumatic injuries of the anterior teeth were 1.8% among the total dental out-patients. 2. By the age group, the twenties was most frequent in both sexes, and the teenagers next. 3. The predominant causes of traumatic injuries in the dental field were traffic accident (23.4%), fighting (19.2%), falling (18.5%), and sports (7.3%). 4. In the classification of injuries of the teeth, uncomplicated crown fractures (31.2%), subluxations (14.7%), and the complicated crown fractures (13.2%) were presented. 5. By the individual tooth in the traumatic cases, the upper cental incisors were most frequently injuried (49.8%). 6. In the treatments fillings and endodontic treatments (33.2%), splints (13.5%), extractions (11.7%) were main after care method.

To investigate patterns and severity of hunting-related emergency traumatic injuries in wild boar hunting dogs. One hundred wild boar hunting dogs with emergency traumatic injuries sustained during wild boar hunting as a result of wild boar attack and accidental shooting of ensnarement in a trap. The retrospective study involved 100 dogs brought to CAMC for treatment of emergency traumatic injury sustained during wild boar hunting in Jeon-buk province from August 2007 to April 2008. Medical information obtained from the medical records included signalment; cause of injury; number, location and severity of injuries; and mortality. The 100 patients displayed 136 injuries (single injury in 71 dogs and multiple injuries in 29 dogs). Causes of the emergency traumatic injuries were wild boar attack (n = 92), accidental shooting (n = 7), and entrapment (n = 1). The thoracic area was the most common site of injury. The most common injury severity score (ISS) was code 2. The mortality rate was 9%, and all deaths involved thoracic injury. Emergency traumatic injuries sustained during wild boar hunting are most commonly thoracic injuries caused by prey attack. The nature of the injuries can differ from those typically encountered by small animal veterinarians.

Purpose: Traumatic peripheral nerve injury (PNI), which occurs in up to 3% of trauma patients, is a devastating condition that often leads to permanent disability. However, knowledge of traumatic PNI is limited. We describe epidemiology and clinical characteristics of traumatic PNI in Korea and identify the predictors of traumatic complete PNI. Methods: A list of enlisted soldier patients who were discharged from military service due to PNI over a 10-year period (2012-2021) was obtained, and their medical records were reviewed. Patients were classified according to the causative events (traumatic vs. nontraumatic) and injury severity (complete vs. incomplete). Of traumatic PNIs, we compared the clinical variables between the incomplete and complete PNI groups and identified predictors of complete PNI. Results: Of the 119 young male patients who were discharged from military service due to PNI, 85 (71.4%) were injured by a traumatic event; among them, 22 (25.9%) were assessed as having a complete injury. The most common PNI mechanism (n=49, 57.6%), was adjacent fractures or dislocations. Several injury-related characteristics were significantly associated with complete PNI: laceration or gunshot wound, PNI involving the median nerve, PNI involving multiple individual nerves (multiple PNI), and concomitant muscular or vascular injuries. After adjusting for other possible predictors, multiple PNI was identified as a significant predictor of a complete PNI (odds ratio, 3.583; P=0.017). Conclusions: In this study, we analyzed the characteristics of enlisted Korean soldiers discharged due to traumatic PNI and found that the most common injury mechanism was adjacent fracture or dislocation (57.6%). Patients with multiple PNI had a significantly increased risk of complete injury. The results of this study contribute to a better understanding of traumatic PNI, which directly leads to a decline in functioning in patients with trauma.

Purpose: To research about maxillofacial traumatic injuries of children in aspects of gender difference, various incidence rates between age, trauma type, cause, monthly and daily incidence rate, type of tooth damage, gingival damage, soft tissue damage, and type of facial bone fracture. Materials and methods: Study group consisted of children under 15 years of age who visited Dental Hospital, School of Dentistry, Kyung Hee University from 2004/7/1 to 2007/6/30 with chief complaint of oral and maxillofacial traumatic injuries. 1,559 cases of traumatic injuries were studied from 1,556 (1,004 male, 552 female) children. Conclusion: 1. There were slightly more boys than girls, giving a male-to-female ratio of 1.82:1.0. The 1-3 year old boys and girls had the highest number of traumatic injuries. 2. Of the 1,556 patients, 68.63% had soft tissue injuries, 50.22% had periodontal injuries, 29.89% had teeth injuries, and 3.85% had maxillofacial bone fractures. 3. Falling down was the most common cause of injury in both sexes. 4. The months with the highest incidence rates were in order May (12.12%), June (11.74%), and October (11.13%). Most of the injuries occurred on weekends. 5. The most common tooth injury was uncomplicated crown fracture, and the most common periodontal injury was subluxation. The majority of traumatizes teeth were the upper central incisors. 6. The most common soft tissue injury was intraoral lacerations. 7. Mandibular fractures were most frequent in facial bone fractures; symphysis, condylar head, and angle fractures were most frequent in mandibular fractures; maxillary and nasal bone fractures were most frequent in midfacial bone fractures.

Traumatic injuries of the diaphragm are not an infrequent occurrence with rise in violence and increasing use of automobiles, more diaphragmatic injuries may be seen. Fifty cases from Severance hospital were reviewed of these there were 27 injuries secondary to blunt trauma and 23 penetrating injuries, and occurred commonly in male. In blunt trauma, right and left diaphragmatic injuries occurred equally. Chest X * ray were normal in 18 cases [36 %], a hemo-and/or pneumothorax was present in 22 cases [44 %], and only 12 cases[24 %] were diagnosed or suspected as diaphragmatic injuries preoperatively. Seventeen cases underwent thoracotomy alone, 19 cases required laparotomy only, and 14 had combined thoracotomy and laparotomy. There were 5 deaths [10 % mortality], and all deaths related to the severity of associated injuries. It was concluded that injuries of the diaphragm should be suspected in all patients with severe blunt torso trauma or penetrating injuries near the diaphragm.

Purpose: Traumatic pancreatic injuries are rare, but their diagnosis and management are challenging. The aim of this study was to evaluate and report our experiences with the management of pancreatic injuries. Methods: We identified all adult patients (age >15) with pancreatic injuries from our trauma registry over a 7-year period. Data related to patients' demographics, diagnoses, operative information, complications, and hospital course were abstracted from the registry and medical records. Results: A total of 45 patients were evaluated. Most patients had blunt trauma (89%) and 21 patients (47%) had pancreatic injuries of grade 3 or higher. Twenty-eight patients (62%) underwent laparotomy and 17 (38%) received nonoperative management (NOM). The overall in-hospital mortality rate was 24% (n=11), and only one patient died after NOM (due to a severe traumatic brain injury). Twenty-two patients (79%) underwent emergency laparotomy and six (21%) underwent delayed laparotomy. A drainage procedure was performed in 12 patients (43%), and pancreatectomy was performed in 16 patients (57%) (distal pancreatectomy [DP], n=8; DP with spleen preservation, n=5; pancreaticoduodenectomy, n=2; total pancreatectomy, n=1). Fourteen (31%) pancreas-specific complications occurred, and all complications were successfully managed without surgery. Solid organ injuries (n=14) were the most common type of associated abdominal injury (Abbreviated Injury Scale ≥3). Conclusions: For traumatic pancreatic injuries, an appropriate treatment method should be considered after evaluation of the accompanying injury and the patient's hemodynamic status. NOM can be performed without mortality in appropriately selected cases.

Purpose: This study investigated the clinical outcomes of trauma patients with blunt thoracic aortic injuries at a single institution. Methods: During the study period, 9,501 patients with traumatic aortic injuries presented to Trauma Center of Gil Medical Center. Among them, 1,594 patients had severe trauma, with an Injury Severity Score (ISS) of >15. Demographics, physiological data, injury mechanism, hemodynamic parameters associated with the thoracic injury according to chest computed tomography (CT) findings, the timing of the intervention, and clinical outcomes were reviewed. Results: Twenty-eight patients had blunt aortic injuries (75% male, mean age, 45.9±16.3 years). The majority (82.1%, n=23/28) of these patients were involved in traffic accidents. The median ISS was 35.0 (interquartile range 21.0-41.0). The injuries were found in the ascending aorta (n=1, 3.6%) aortic arch (n=8, 28.6%) aortic isthmus (n=18, 64.3%), and descending aorta (n=1, 3.6%). The severity of aortic injuries on chest CT was categorized as intramural hematoma (n=1, 3.6%), dissection (n=3, 10.7%), transection (n=9, 32.2%), pseudoaneurysm (n=12, 42.8%), and rupture (n=3, 10.7%). Endovascular repair was performed in 71.4% of patients (45% within 24 hours), and two patients received surgical management. The mortality rate was 25% (n=7). Conclusions: Traumatic thoracic aortic injuries are life-threatening. In our experience, however, if there is no rupture and extravasation from an aortic injury, resuscitation and stabilization of vital signs are more important than an intervention for an aortic injury in patients with multiple traumas. Further study is required to optimize the timing of the intervention and explore management strategies for blunt thoracic aortic injuries in severe trauma patients needing resuscitation.
