We evaluated forty cases of traumatic diaphragmatic ruptures that we have experienced from Mar. 1976 to Mar. 1992. Thirty patients were male and 10 were female[M:F=3:1]. The age distribution was ranged from 2 to 76 years with the mean age of 35 years. The traumatic diaphragmatic ruptures were due to blunt trauma in 26 cases[traffic accident 20, fall down 4, others 2] and penetrating trauma in 14 cases[stab wound 13, gun shot 1]. In the blunt trauma, 21 of 26 cases were diagnosed within 24 hours after injury and all cases except one in penetrating trauma were diagnosed within 24 hours. In the blunt trauma, the rupture site was located in the left in 20 cases and in the right in 6 cases. In the penetrating trauma, the rupture site was located in the left in 10 cases and in the right in 4 cases. The repair of 40 cases were performed with thoracic approach in 19 cases, thoracoabdominal approach in 17 cases and abdominal approach in 4 cases. The postoperative mortality was 7.5 %[3/40]. The causes of death were septic shock[1], acute renal failure[1] and hypovolemic shock[1].

We evaluated sixteen patients of traumatic diaphragmatic injuries that we have experienced from Jan. 1987 to Aug 1993. Age was ranged from 6 to 71 years, predominantly in the fourth and fifth decades. 13 were male and 3 were female, a ratio of 4.3: 1. Blunt trauma was develped in 11 [Lt 7, Rt 4], penetrating trauma in 5 [Lt 2, Rt 3]. Preoperative diagnosis of diaphragmatic injury was possible in 8 patients [72.2 %] in blunt trauma, and 1 patient [20 %] in penetrating trauma. 8 cases[54.5%] in blunt trauma, and 4 cases in penetrating trauma were treated within 24 hours,meanwhile, patients treated after 10 days were 3, all by blunt trauma.The repair of 16 cases were performed with thoracic approach in 4 cases, thoracoabdominal approach in 3 cases, and abdominal approach in 9 cases. The herniated organs in thorax were stomach [5], colon [3], liver [2], and pancreas [1]. Postoperative complication were developed in 9cases[56.3%] significantly related with delayed operation time [p < 0.01 ]. Hospital mortality was 12.5 % [2/16], and the causes of death were hypovolemic shock in one and hepatic failure due to portal vein rupture in another.

Retained wooden foreign bodies following penetrating trauma are a difficult diagnostic problem. However, penetrating wooden foreign bodies of head and neck have the potential for misinterpretation or failure to detect such foreign bodies on CT. Given the likelihood that such a miss will result in an abscess or neurovascular injury, we present the method with higher window settings, they had a higher attenuation with a unique striated internal architecture and different Hounsfield numbers readily differentiate air and non-air hypodense material such as fat, or possibly wood. Being aware of the potential appearance of wood, we may also find CT useful in excluding small retained fragments in postoperative patients with persistent symptoms. This article presents two cases in which wooden foreign bodies of head and neck were present with CT evaluation.

Penetrating chest trauma may result in significant intracardiac injury. A traumatic ventricular septal defect is a rare complication that requires surgical management, particularly if heart failure ensues. We report a case of delayed repair of an outlet-type ventricular septal defect and perforation of the aortic and pulmonary valve leaflets following a stab wound. This report highlights diagnostic and surgical considerations and also presents an opportunity to review the conotruncal anatomy, which may be relatively unfamiliar to many adult cardiac surgeons.

Traffic accidents involving agricultural machinery have been decreasing, but mortality is still high due to a lack of safety devices such as seat belts. Furthermore, secondary damage, such as abdominal impalement injury caused by loaded materials, is more likely to occur, and this type of injury leads to a poor prognosis. Impalement with pipes is often more fatal than other penetrating injuries because the diameter of the pipe is usually larger in size than other loaded materials. We report a case of a 72-year-old man with secondary abdominal impalement injury caused by a scaffolding pipe following a traffic accident.

Purpose: Although trauma is the most common cause of death under age 18, Korean national pediatric trauma data has lack of clinical data. This study is to prepare manpower resources, equipment, and make a correct policy decision on pediatric trauma victims Methods: The study enrolled 528 patients under age 16 with traumatic injury visited Wonju Severance Christian Hostpital Trauma Center, from February 12, 2015 to December 31, 2016. We analyzed the distribution of gender, age, place and time of the accident, injury mechanism, injury severity, and injured organ by medical record. Results: The major injury mechanisms were blunt injury in 485 (91.90%), penetrating injury in 27 (5.10%), burn in 13 (2.50%), near drowning in 2 (0.40%), and foreign body ingestion in 1 (0.20%). Ninety-seven (18.4%) patients were injured at home and 67 (12.7%) patients were injured at school. The overall mortality rate was 1.13% (n=6). 5 mortalities were related to automobile accident and one was fall down. Mean Injury Severity Score (ISS) was 4 (2, 8). No statistical significance was observed in the mean ISS between each age group. The peak time of accident occurrence was between 16 and 17 o'clock. The mean ISS was higher in blunt injury group than penetrating injury with statistical significance ($6.50{\pm}7.60$ vs. $3.00{\pm}8.10$; p<0.05). The most common injury site was upper extremity. Mean ISS was highest in thorax injury. However, mean ISS of thorax injury was higher with statistical significance only compared with face, neck and upper extremity injury. Conclusions: We reported our pediatric trauma patients data of our hospital level I trauma center, which is the only one level I trauma center of Gangwon Province. These data is useful to prevent and prepare for pediatric trauma.

Experimental studies were performed to investigate the eye injury risks by different BB pellet materials. Four different BB pellet materials were used: plastic (P), silicon (S), rubber (R) and plastic covered with silicon (SR). The BB pellet images penetrating into the gelatine simulant were recorded by a high-speed video camera. The results obtained from the different pellet materials were discussed in terms of impact velocity and penetration depth; threshold velocity and projectile sectional density; eye injury risks by normalized energies. It was found that the P pellets caused higher impact velocity while the lower was SR pellets. The penetration depth and threshold velocity of the pellets were dependent on the impact velocity of the pellets, and the P pellets resulted in the higher eye injury risk while the lower was SP.

A clinical evaluation was performed on 17 cases of the cardiac and great vessel injuries above the subclavian vessel at the Department of Thoracic and Cardiovascular Surgery, Chungnam National University Hospital from April, 1980 to September, 1986. The results were as follows: 1. Sex distribution were 13 cases in male and 4 cases in female. In age range, second and third decades occupied in about 65% of total cases. 2. Modes of injury were penetrating wound is 14 cases and nonpenetrating wound in 3 cases. The stab wounds by knife were most frequent. 3. Time interval from injury to operation was mean 103 minutes. 4. Surgical approaches were performed with thoracotomy in 9 cases, median sternotomy in 3 cases and direct incision above the wound. 5. Sites of injury were heart in 10 cases and great vessel in 7 cases. The right ventricular injury was most common as 7 cases. 6. Operative procedures were performed with simple closure, vascular graft anastomosis and ligation. There was no postoperative death.

Apenetrating head injury by an arrow is extremely rare being only two cases reported in the literature. We report a case of 12-year-old boy who presented with an arrow lodged at the posterior fossa through nasal nostril. He was slightly drowsy, but neurologically intact except a sixth nerve palsy in the left eye. Brain CT showed no intracerebral hemorrhage. The arrow was entered through the right nostril and the tip was stucked in the left cere-bello-pontine angle through the sphenoid sinus. We removed the arrow without craniotomy since the tip was verified smooth and no cerebral arteries were in contact with the arrow. The patient recovered well without any significant complications. The sixth nerve palsy resolved completely after six months. The verification of the shape of the offending material, a retrograde removal of the arrow in the direction of its line of trajectory, and an identification of adjacent cerebral arteries seem to be important in the management of this type of injury.
