골반골 골절은 고에너지 손상이며 주변 조직 및 장기의 손상이 동반되는 경우가 흔하다. 골반 외상 환자에서 적절한 치료가 제공되지 않으면 사망률이 높아지므로 수상 초기에 적극적인 치료를 요하게 된다. 하지만 광범위한 수술을 시행하기에는 환자의 상태가 허락되지 않는 경우가 많아서 최소 침습적인 수술을 고려하게 된다. 치골의 경피적 고정은 피부 절개를 크게 하지 않고도 골반의 전방부 안정성을 획득할 수 있는 방법으로 비교적 쉽게 적용할 수 있어 여러 문헌에서 소개되고 있다. 그러나 대부분의 문헌에서는 비전위성 골절에 대한 나사 고정을 기술하고 있으며 전위성 골절을 경피적 나사 고정으로 치료할 때 비구의 관절면을 침범하지 않는 위치로 나사를 삽입하는 것이 어려운 점은 간과되고 있다. 저자는 치골의 전위성 골절의 경피적 나사 고정 시 구부러진 유도핀을 이용하여 관절면의 침범을 피하면서 유관나사를 쉽게 삽입할 수 있었기에 본 술식을 소개하고자 한다.

Objective : The diagnosis of insufficiency fractures of the sacrum in an elder population increases annually. Fractures show very different morphology. We aimed to classify sacral insufficiency fractures according to the position of cortical break and possible need for intervention. Methods : Between January 1, 2008 and December 31, 2014, all patients with a proven fracture of the sacrum following a low-energy or an even unnoticed trauma were prospectively registered : 117 females and 13 males. All patients had a computer tomography of the pelvic ring, two patients had a magnetic resonance imaging additionally : localization and involvement of the fracture lines into the sacroiliac joint, neural foramina or the spinal canal were identified. Results : Patients were aged between 46 and 98 years (mean, 79.8 years). Seventy-seven patients had an unilateral fracture of the sacral ala, 41 bilateral ala fractures and 12 patients showed a fracture of the sacral corpus : a total of 171 fractures were analyzed. The first group A included fractures of the sacral ala which were assessed to have no or less mechanical importance (n=53) : fractures with no cortical disruption ("bone bruise") (A1; n=2), cortical deformation of the anterior cortical bone (A2; n=4), and fracture of the anterolateral rim of ala (A3; n=47). Complete fractures of the sacral ala (B; n=106) : parallel to the sacroiliac joint (B1; n=63), into the sacroiliac joint (B2; n=19), and involvement of the sacral foramina respectively the spinal canal (B3; n=24). Central fractures involving the sacral corpus (C; n=12) : fracture limited to the corpus or finishing into one ala (C1; n=3), unidirectional including the neural foramina or the spinal canal or both (C2; n=2), and horizontal fractures of the corpus with bilateral sagittal completion (C3; n=8). Sixty-eight fractures proceeded into the sacroiliac joint, 34 fractures showed an injury of foramina or canal. Conclusion : The new classification allowes the differentiation of fractures of less mechanical importance and a risk assessment for possible polymethyl methacrylate leaks during sacroplasty in the direction of the neurological structures. In addition, identification of instable fractures in need for laminectomy and surgical stabilization is possible.

The urinary bladder retroflexion, flipped over backwards into the pelvic canal, by trauma has been rarely reported in dogs. This paper describes clinical and radiological features of urinary bladder retroflexion in two dogs with a history of traffic accident. The main clinical signs were hind limb lameness, severe pain and dysuria. Radiography and ultrasonography were performed to evaluate the patient's damages. No remarkable findings were observed except pelvic fracture on survey radiograph. On cystourethrography, caudal displacement and retroflexion of the bladders were identified. Cystopexy was performed and the bladders were repositioned. After surgery one dog with severe azotemia and bilateral hydroureteronephrosis was deteriorated noticeably and euthanized by request of the owner, while the other dog was recovered no recurrence of the problem by 12 months post-surgery. It should be considered that contrast study and serial assessment in urinary tract be important to demonstrate the evidence of bladder retroflexion and evaluate the prognosis in dogs with severe trauma.

Traumatic uterine rupture is uncommon but can be fatal and life-threatening for both the mother and infant. In addition to complications caused by trauma itself, such as pelvic fracture, gestational complications such as placental abruption, abortion, premature labor, rupture of membranes, maternal death, and stillbirth can occur. In particular, fetuses have been reported to have a high mortality rate in cases of traumatic uterine rupture. A 35-year-old pregnant female patient fell from the fourth floor and was admitted to our trauma center. We observed large hemoperitoneum, pelvic fractures, and spleen laceration, and the fetus was presumed to be located outside the uterus. The pregnant woman was hemodynamically unstable. Although the fetus was stillborn, angioembolization and surgical treatment were properly performed through collaboration with an interventional radiologist, obstetrician, and trauma surgeons. After two orthopedic operations, the patient was discharged after 34 days. This case report suggests the importance of a multidisciplinary approach in the treatment of pregnant trauma patients.

Fat embolism refers to the presence of fat droplets within the peripheral and lung microcirculation with or without clinical sequelae. However, early diagnosis of fat embolism is very difficult because the embolism usually does not show at the computed tomography as a large fat complex within vessels. Forty-eight-year-old male with pedestrian traffic accident ransferred from a local hospital by helicopter to the regional trauma center by two flight surgeons on board. At the rendezvous point, he had suffered with dyspnea without any airway obstruction sign with 90% of oxygen saturation from pulse oximetry with giving 15 L of oxygen by a reserve bag mask. The patient was intubated at the rendezvous point. The secondary survey of the patient revealed multiple pelvic bone fracture with sacrum fracture, right femur shaft fracture and right tibia head fracture. Abdominal computed tomography was performed in 191 minutes after the injury and fat embolism with Hounsfield unit of -86 in his right common iliac vein was identified. Here is a very rare case that mass of fat embolism was shown within common iliac vein detected in computed tomography. Early detection of the fat embolus and early stabilization of the fractures are essential to the prevention of sequelae such as cerebral fat embolism.

This study was conducted to evaluate and analyze fractures types in wild mammals in Korea. Wild mammals treated at 3 wildlife centers in Korea were included. Of the 63 cases included in this study, water deer was the most common species encountered with fractures. We determined 85 different fracture sites, with maximum lumber vertebral fractures followed by femoral, tibial and pelvic fractures. External skeletal fixator (ESF)-intramedullary (IM) pin (IM+ESF tie-in fixation) was the most common method applied for the surgical treatment of mammals. Lumbar vertebrae and femur were the most common bones involved. The findings of this study are expected to provide information for veterinarians regarding the frequency and characteristics of fractures in wild mammals and serve as a basic database for the types and outcomes of fractures in wild mammals.

Purpose: Management of soft-tissue defect after open tibial fractures includes immediate and repeated debridement, skeletal stabilization, and early soft-tissue coverage with muscle flaps. The purpose of this study was to evaluate the outcome of the free rectus abdominis muscle flap (RA flap) for treatment of open fractures of the tibia and to discuss its advantages compared with the latissimus dorsi muscle flap (LD flap) in poly trauma patients. Materials and Methods: We performed a retrospective review of 5 patients who had a severe (Gustilo IIIb or IIIc) open fracture of the tibia treated with RA flap from May 2003 to March 2006. All were men, and the mean age was 46.6 years (range, $28{\sim}68$). Three patients had combined injuries such as pelvic bone fractures, multiple rib fractures with hemothorax, and contralateral tibial fracture. All patients received RA flap within 7 days after trauma except two with established chronic osteomyelitis. Results: All flaps survived, and there was no marginal flap necrosis. During the follow-up period, there was no evidence of persistent or recurrent osteomyelitis. The size of RA flap ranged from $8{\sim}20\;cm$ in length and $6{\sim}10\;cm$ in width. The average time required for RA flap elevation was 32 minutes, which is shorter than LD flap. Flap elevation could be done in supine position which is essential in poly trauma patients. Conclusion: Although a wide variety of options are available, RA flap is regarded as an optimal method for coverage of soft-tissue defect of the open tibial fracture in poly trauma patients. LD flap is reserved for large sized soft-tissue defect which cannot be covered by RA flap.

Chest injuries due to blunt trauma often result in severe derangements that lead to death. And we have to diagnose and treat the patients who have blunt chest trauma immediately and appropriately. A clinical analysis was made on 324 cases of chest injury due to blunt trauma experienced at department of Thoracic and Cardiovascular Surgery, College of Medicine, Kyung Hee University during 8-year period from 1972 to 1979. Of 324 patients of blunt chest injuries, there were 189 cases of rib fracture, 121 of hemothorax or/and pneumothorax, 108 of soft tissue injury of the chest wall only, 41 of lung contusion, 24 of flail chest, 13 of scapular fracture, 7 of diaphragmatic rupture and others. The majority of blunt chest injury patients were traffic accident victims and falls accounted for the next largest group of accidents. Chest injuries were frequently encountered in the age group between 3rd decade and 4th decade [60%] and 238 patients were male comparing to 86 of female [Male: Female = 3:1 ]. In the patients who have the more number of fractured ribs, the more incidence of intrathoracic injury and intraabdominal organ damage were found. The principal associated injuries were head injury on 58 cases, long bone fractures on 37, skull fractures on 12, pelvic fractures on 10, renal injuries on 6 and intraabdominal organ injuries on 5 patients. The principle of early treatment of chest injury due to blunt trauma were rapid reexpansion of the lung by closed thoracotomy which was indicated on 96 cases, but open thoractomy was necessary on 14 cases because massive bleeding, intrapleural hematoma and/or fibrothorax, or diaphragmatic laceration-On 15 cases who were young and have multiple rib fracture with severe dislocation delayed elective open reduction of the fractured ribs with wire was done on the purpose of preserving normal active life. The over all mortality was 2.8% [9 of 324 cases] due to head injury on 3 cases, massive bleeding on 2,wet lung syndrome, acute renal failure on 1 and septicemia on 1 patient.

A 52-year-old man experienced blunt trauma upon falling from a height of 40 m while trying to repair the elevator. The patient's systolic blood pressure and hemoglobin levels were 60 mmHg and 7.0 g/dL, respectively, upon admission. A large volume of bloody discharge was observed in the open wound of the perianal area and sacrum. A computed tomography scan revealed an open comminuted sacral fracture with multiple contrast blushes. He underwent emergency laparotomy. Both internal iliac artery ligations were performed to control bleeding from the pelvis. Protective sigmoid loop colostomy was performed because of massive injury to the anal sphincters and pelvis. Pad packing was performed for a sacral open wound and perineal wound at the prone position. After resuscitation of massive transfusion, he underwent the second operation 2 days after the first operation. The pad was removed and the perineal and sacral open wounds were closed. After the damage-control surgery, he recovered safely. In this case, the hemodynamically unstable, open comminuted sacral fracture was treated safely by internal iliac artery ligation with pad packing.

Purpose: The aim of this study was to determine which factors contribute to the surgical treatment outcomes of acetabular fractures. Simultaneously, we aim to report on the treatment results after our hospital was designated as the focused training center for trauma. Methods: We conducted a retrospective review of all patients who experienced acetabular fractures from January 1, 2014 to May 1, 2017 and visited our hospital. Patients who had associated pelvic ring fractures or were lost to the one-year follow-up were excluded; a total of 37 fractures were evaluated. We evaluated the clinical results using the scoring system of Merle $d^{\prime}Aubign\acute{e}$ (MDA) and grade of Brooker for heterotopic ossification. Results: Thirty-seven patients (31 men and 6 women) were identified. The mean injury severity score (ISS) was 8.7, with 32.4% of patients having a score >15. The average blood transfusion in the first 24 hours was 0.54 pints. Falling was the most common injury mechanism (32.4%). Chest injury was the most common associated injury (16.2%), followed by head injury (13.5%). The posterior wall and both column fracture were the most common (37.8%) fracture patterns. Excellent and good clinical grades of MDA included 28 patients (75.6%) and fair and poor grades included nine (24.3%), respectively. Four patients were diagnosed with a post-operative infection (10.8%); one out of four patients who had co-morbidity died (2.7%), and another patient underwent a replacement surgery (2.7%). Multivariate analysis showed that age and operation time were associated with MDA. In addition, operation time and ISS were significant co-factors of the Brooker grade. Conclusions: Korea University Guro Hospital showed similar treatment results of acetabular fractures compared to other publications. The age and operation time were co-factors of the clinical outcome of this fracture. Additionally, increased operation time and injury severity score were suggested to increase the Brooker grade.
