The aim of this review is to introduce the progress in trauma surgery made during war. In the 16th century, Paré reintroduced ligature of arteries, which had been introduced by Celsus and Galen, instead of cauterization during amputation. Larrey, a surgeon in Napoleon's military, adapted the "flying artillery" to serve as "flying ambulances" for rapid transport of the wounded. He established rules for the triage of war casualties, treating wounded soldiers according to the seriousness of their injuries and the urgency of medical care. To treat fractures and tuberculosis, Thomas created the "Thomas splint", which was used to stabilize fractured femurs and prevent infection; in World War I (WWI), use of this splint reduced the mortality of compound femur fractures from 87% to less than 8%. During WWI, Cushing systematized the treatment of head injuries, reducing mortality among head injury patients. Gillies repaired facial injuries, and his experiences became the basis of craniofacial and aesthetic surgery. In WWII, McIndoe discovered that immersion in saline promoted burn healing and improved survival rates, and thus began saline baths and early grafting instead of using tannic acid. A high mortality rate in patients with acute renal failure was noted in WWII and the Korean War. In the Korean War, Teschan used the Kolff-Brigham dialyzer. The first use of medevac with helicopters was the evacuation of three British pilot combat casualties by the US Army in Burma during WWII. As a lotus blooms in the mud, military surgeons have contributed to trauma surgery during wartime.

Purpose: The first regional trauma center selected in Korea was the Gachon University Gil hospital regional trauma center; expectation on its role has been high because of its location in the Seoul metropolitan region. To determine if those expectations are being met, we analyzed the patients visiting the center and their treatment experiences for the past 3 years in order to propose a standard for the operation of a trauma center. Methods: The visiting route, visiting methods, performance of emergency surgery, the ward and the length of stay, the injury mechanism, the injury severity score (ISS), the department that managed the surgery, and the cause of death were analyzed for 367 patients visiting the center from its establishment in June 2011 through December 2013. Results: The mean age of the patients was 47 years (285 male and 82 female patients). A total of 187 patients directly visited the center whereas 180 were transferred to the center. Traffic accidents comprised the majority of injury mechanisms, and 178 patients underwent emergency surgery. The mean length of stay per patient was 11 days for those in the ICU and 27 days for those in a general ward. These patients occupied 4 beds in the ICU and 10 beds in the general ward per day. A total of 1.21 surgeries were performed per patient, and the mean number of surgeries performed per day was 0.49. The mean ISS was 15.91, and 183 patients (50%) had an ISS of ${\geq}16$. Thirty-one patients died; they had a mean ISS of 28.42. The most frequent cause of death was multi-organ failure. The mean number of treatment consultations during a patient's stay was 6.32. Forty-five patients (13%) were discharged from the center, and 291 (79%) were transferred to another hospital. Conclusion: A systematic approach to establishing a treatment model for trauma patients, including injury mechanism, multidisciplinary treatment, and trauma surgeon intervention, is required for treating trauma patients.

Mandibular trauma is developed due to traffic accident, fall down, industrial injury, and others. TMJ disorder is usually also developed after facial traumatic injury. Many authors suggested that disc displacement or tearing, acute synovitis, TMJ ankylosis, traumatic arthritis, or effusion are developed after facial trauma. It is still very controversible what is the best treatment of TMJ injury such as condylar fracture and meniscal injury. In TMJ injury, synovial inflammation is developed and pain mediators such as prostaglandin E2 or leukotriene B4 are released from the synovial membrane. This can be a cause of TMJ disorder. I present a variety of experimental study about the condylar fracture and meniscal injury and enzyme-immunoassay of synovial fluid after mandibular trauma that have been studied since 1992 and establish the treatment criteria of traumatic TMJ injury. I think that the treatment option of condylar fracture depends upon the surgeon's criteria exclusively. There are no significant differences between conservative and surgical treatment. If the aggressive functional physical therapy and long-term followup be performed, the favorable functional recovery of TMJ can be obtained. And I think that the initial surgical management of meniscus of TMJ is unnecessary in condylar fracture. And also arthrocentesis can be available to release the patient's subjective symptoms and improve the healing of injured TMJ.

Posttraumatic pseudoaneurysm of the superficial temporal artery is very rare and occurs secondary to trauma. Clinical diagnosis is based on past history of trauma and physical examination and can be confirmed by duplex ultrasonogram, digital subtraction angiography, CT and MRI. Ligation of proximal and distal ends of the superficial temporal artery and excision of the pseudoaneurysm has been the standard treatment. Compressive therapy, endovascular coil embolization, percutaneous thrombin injection under ultrasound guidance have been reported as alternative treatment methods. When surgical excision of the superficial temporal artery pseudoaneurysm is performed, surgeon must be concerned about the anatomical relation between superficial temporal artery and temporal branches of the facial nerve. In this article, we report a rare case of superficial temporal artery pseudoaneurysm with some review of the literatures about anatomical relation between superficial temporal artery and temporal branches of facial nerve.

Pelvic bone fracture with hemodynamic instability is fatal and the mortality rate can range up to 40%. Despite the big advances in the treatment of massive bleeding and hemorrhagic shock, the mortality associated with hemodynamically unstable pelvic bone fractures remains high. The gold standard of treatment for pelvic bone fracture with hemodynamic instability has not yet been determined and is an issue of main discussion among many doctors. Retroperitoneal packing is not yet wide spread in Korea, but is a good modality for managing of massive bleeding from pelvic bone fractures when an angiography suite or an expert surgeon is not available. A vacuum-assisted closure (VAC) system can also be applied with retroperitoneal packing in the manner of damage control surgery and open abdomen surgery. We present the case of a 51-year-old male who had a pelvic bone fracture with massive bleeding. We performed retroperitoneal gauze packing with a VAC system for the first time. The postoperative vital signs of patient were immediately stable, the massive bleeding was easily and quickly controlled, and the amount of transfusion of blood components was reduced.

Femoral head fractures with associated hip dislocations substantially impact the functional prognosis of the hip joint and present a surgical challenge. The surgeon must select a safe approach that enables osteosynthesis of the fracture while also preserving the vascularization of the femoral head. The optimal surgical approach for these injuries remains a topic of debate. A 44-year-old woman was involved in a road traffic accident, which resulted in a posterior iliac dislocation of the hip associated with a Pipkin type II fracture of the femoral head. Given the size of the detached fragment and the risk of incarceration preventing reduction, we opted against attempting external orthopedic reduction maneuvers. Instead, we chose to perform open reduction and internal fixation using the Watson-Jones anterolateral approach. This involved navigating between the retracted tensor fascia lata muscle, positioned medially, and the gluteus medius and minimus muscles, situated laterally. During radiological and clinical follow-up visits extending to postoperative month 15, the patient showed no signs of avascular necrosis of the femoral head, progression toward coxarthrosis, or heterotopic ossification. The Watson-Jones anterolateral approach is a straightforward intermuscular and internervous surgical procedure. This method provides excellent exposure of the femoral head, preserves its primary vascularization, allows for anterior dislocation, and facilitates the anatomical reduction and fixation of the fracture.

Objective : The sub-axial injury classification (SLIC) and severity scale was developed to decide whether to operate the cervical injured patient or not, but the reliability of SLIC and severity scale among the different physicians was not well known. Therefore, we evaluated the reliability of SLIC among a spine surgeon, a resident of neurosurgery and a neuro-radiologist. Methods : In retrograde review in single hospital from 2002 to 2009 years, 75 cases of sub-axial spine injured patients underwent operation. Each case was blindly reviewed for the SLIC and severity scale by 3 different observers by two times with 4 weeks interval with randomly allocated. The compared axis was the injury morphology score, the disco-ligamentous complex score, the neurological status score and total SLIC score; the neurological status score was derived from the review of medical record. The kappa value was used for the statistical analysis. Results : Interobserver agreement of SLIC and severity scale was substantial agreement in the score of injury morphology [intraclass correlation (ICC)=0.603] and total SLIC and severity sacle (ICC value=0.775), but was fair agreement in the disco-ligamentous complex score (ICC value= 0.304). Intraobserver agreements were almost perfect agreement in whole scales with ICC of 0.974 in a spine surgeon, 0.948 in a resident of neurosurgery, and 0.963 in a neuro-radiologist. Conclusion : The SLIC and severity scale is comprehensive and easily applicable tool in spine injured patient. Moreover, it is very useful tool to communicate among spine surgeons, residents of neurosurgery and neuro-radiologists with sufficient reproducibility.

Objectives: Any change in maxilla and mandible position can alter the upper airway, and any decrease in the upper airway can cause sleep disorders. Thus, it is necessary to assess airway changes after repositioning of the maxilla and mandible during orthognathic surgery. The purpose of this study was to evaluate linear and volumetric changes in the upper airway after bimaxillary surgery to correct class III malocclusion via cone-beam computed tomography (CBCT) and to identify correlations between linear and volumetric changes. Materials and Methods: This was a prospective cohort study. CBCTs from 10 class III patients were evaluated before surgery and three months after. The Wilcoxon one-sample test was used to evaluate the differences in measurements before and after surgery. Spearman's rank correlation coefficient was used to test the correlation between linear and volumetric changes. Results: The results show that the nasopharyngeal space increased significantly, and that this increase correlated with degree of maxillary advancement. No significant changes were found in volumes before and after surgery. A correlation was found between linear and volumetric oropharyngeal changes. Conclusion: Bimaxillary surgical correction of class III malocclusion did not cause statistically significant changes in the posterior airway space.

Background: We analyzed association between viewing two-dimensional computed tomography (2D CT) images in addition to radiographs with radial head treatment recommendations after accounting for patient and surgeon factors in a survey-based experiment. Methods: One hundred and fifty-four surgeons reviewed 15 patient scenarios with terrible triad fracture dislocations of the elbow. Surgeons were randomized to view either radiographs only or radiographs and 2D CT images. The scenarios randomized patient age, hand dominance, and occupation. For each scenario, surgeons were asked if they would recommend fixation or arthroplasty of the radial head. Multi-level logistic regression analysis identified variables associated with radial head treatment recommendations. Results: Reviewing 2D CT images in addition to radiographs had no statistical association with treatment recommendations. A higher likelihood of recommending prosthetic arthroplasty was associated with older patient age, patient occupation not requiring manual labor, surgeon practice location in the United States, practicing for five years or less, and the subspecialties "trauma" and "shoulder and elbow." Conclusions: The results of this study suggest that in terrible triad injuries, the imaging appearance of radial head fractures has no measurable influence on treatment recommendations. Personal surgeon factors and patient demographic characteristics may have a larger role in surgical decision making. Level of evidence: Level III, therapeutic case-control study.

Purpose: Preoperative planning has become essential in performance of total hip arthroplasty (THA). However, data regarding the effect of the planner's experience on the accuracy of digital preoperative planning is limited. The objective of this study was to assess the accuracy of digital templating in THA based on the surgeon's experience. Materials and Methods: A retrospective study was conducted. An analysis of 98 anteroposterior pelvic radiographs, which were individually templated by four surgeons (two hip surgeons and two orthopaedic residents) using TraumaCad^® digital planning, was performed. A comparison of preoperatively planned sizes with implanted sizes was performed to evaluate the accuracy of predicting component size. The results of preoperative planning performed by hip surgeons and orthopaedic residents were compared for testing of the planner's experience. Results: Femoral stem was precisely predicted in 32.4% of cases, acetabular component in 40.3%, and femoral offset in 76.7%. Prediction of cup size showed greater accuracy than femoral size among all observers. No differences in any variable were observed among the four groups (acetabular cup P=0.07, femoral stem P=0.82, femoral offset P=0.06). All measurements showed good reliability (intraclass correlation coefficient [ICC] acetabular cup: 0.76, ICC femoral stem: 0.79). Conclusion: The results of this study might suggest that even though a surgeon's experience supports improved precision during the planning stage, it should not be restricted only to surgeons with a high level of experience. We consider preoperative planning an essential part of the surgery, which should be included in training for orthopaedics residents.
