1/351. Analysis of blunt trauma injuries: vertical deceleration versus horizontal deceleration injuries.There are several similarities found in blunt trauma injuries to humans sustained as a result of vertical deceleration (falling) and those sustained as a result of deceleration in a horizontal plane (automobile accidents). However, examination of the patterns of traumatic skeletal injuries can distinguish those injuries associated with falling from heights from those associated with automobile accidents. While there is considerable variation within each type of blunt trauma injury dependent on the angle at which one falls or is struck, there are several characteristic skeletal features associated with each type of trauma. In this study we review both the current literature and human skeletal remains from the University of new mexico's Documented Collection known to have been subjected to blunt trauma. This collection is used to characterize and differentiate the pattern of skeletal injuries to various parts of the body for each type of trauma. These assessments are applied to investigate the traumatic skeletal lesions observed in a forensic case where the manner of death is unknown. Analyses suggest two possible scenarios that would explain the death of the individual investigated, with death most likely related to a vehicular-pedestrian accident.- - - - - - - - - - ranking = 1keywords = injury (Clic here for more details about this article) |
2/351. Inferomedial (subsustentacular) dislocation of the navicular: a case report.A unique case of subsustentacular dislocation of the navicular is presented. The authors propose that such a severe displacement cannot occur until there is complete instability across the whole midfoot. The mechanism of injury and the treatment options are discussed. In the present case, there was late collapse of the foot into abduction because the lateral column was not primarily stabilized. Avascular necrosis is a common complication which leads to navicular collapse. A midfoot arthrodesis gave a good result in our patient.- - - - - - - - - - ranking = 1keywords = injury (Clic here for more details about this article) |
3/351. resuscitation of the multitrauma patient with head injury.head injury remains the leading cause of death from trauma. The definitive method for eliminating preventable death from traumatic brain injury remains elusive. New research underscores the danger of inadequate or inappropriate support of oxygenation, ventilation, and perfusion to cerebral tissues. The belief that sensitivity to hypotension makes the patient with head injury fundamentally different is critical to nursing strategies. The conventional concept that fluid restriction decreases cerebral edema in patients with head injury must be weighed against mounting evidence that aggressive hemodynamic support decreases the incidence of subsequent organ system failure and secondary brain injury. New evidence has triggered a scrutiny of conventional interventions. A search for optimal treatments based on prospective randomized trials will continue. Development of neuroprotective drugs and use of hypertonic saline may be on the horizon. In an effort to ensure optimal outcome, contemporary trauma nursing must embrace new concepts, shed outmoded therapy, and ensure compliance with the basic tenets of critical care for the multitrauma patient with head injury.- - - - - - - - - - ranking = 10keywords = injury (Clic here for more details about this article) |
4/351. High-energy bilateral talar neck fractures secondary to motocross injury.The authors present a case of bilateral Hawkins type II talar neck fractures sustained during a motocross race in a 23 year old man. Due to the complexity of the injuries, open reduction with internal fixation and primary subtalar joint arthrodesis was performed bilaterally. This is one of the few cases of bilateral talar neck fractures reported in the literature in the past 15 years and one of the first utilizing open reduction and internal fixation with concomitant subtalar joint arthrodesis as a primary treatment.- - - - - - - - - - ranking = 4keywords = injury (Clic here for more details about this article) |
5/351. Multivascular trauma on an adolescent. Perioperative management.Penetrating vascular injury, in particular at the neck, is a life-threatening trauma not only of the nature and the anatomic proximity of cardiovascular, aerodigestive, glandular and neurologic system but also of the development of early and late complications. The following case report describes our experience with a penetrating wound patient, who was admitted to our emergencies twelve hours after the accident. The only demonstrable objective signs included a large hematoma at the right-side of the neck and distended mediastinum on the chest X-ray. As the patient was cardiovascularly unstable he was immediately transported to the theater without any angiography. The mandatory operative exploration was initially unsuccessful and a median sternotomy with a standard cardiopulmonary bypass and deep hypothermia circulatory arrest was established to restore all the vascular lesions. Actually, the patient was in critical condition with a rupture of the right internal jugular vein, a large pseudoaneurysm of the innominate artery and an avulsion of the ascending aorta with the suspicion of a cardiac tamponade. The postoperative period lasted two full months, while complications appeared. The substantial message from this multivascular trauma is the early diagnosis of the life-threatening complications as exsanguinations, ventricular fibrillation and the ability to minimize postoperative complications, which will impair the normal functional life of the patient.- - - - - - - - - - ranking = 1.0036276536244keywords = injury, chest (Clic here for more details about this article) |
6/351. aortic rupture as a result of low velocity crush.A case of aortic disruption in a 35 year old lorry driver is described. This occurred as a result of a low velocity crushing force. Clinicians should be aware that this mechanism of injury may result in aortic disruption as well as the more commonly mentioned severe deceleration force.- - - - - - - - - - ranking = 1keywords = injury (Clic here for more details about this article) |
7/351. Traumatic fracture of the hyoid bone: three case presentations of cardiorespiratory compromise secondary to missed diagnosis.hyoid bone fractures secondary to blunt trauma other than strangulation are rare (ML Bagnoli et al., J Oral Maxillofac Surg 1988; 46: 326-8), accounting for only 0.002 per cent of all fractures. The world literature reports only 21 cases. Surgical intervention involves airway management, treatment of associated pharyngeal perforations, and management of painful symptomatology. The importance of hyoid fracture, however, rests not with the rarity of it, but with the lethal potential of missed diagnosis. We submit three cases with varying presentations and management strategies. All three of our cases incurred injury by blunt trauma to the anterior neck. Two patients required emergent surgical airway after unsuccessful attempts at endotracheal intubation. One patient presented without respiratory distress and was managed conservatively. After fracture, the occult compressive forces of hematoma formation and soft tissue swelling may compromise airway patency. It is our clinical observation that hypoxia develops rapidly and without warning, leading to cardiorespiratory collapse. With endotracheal intubation prohibited by obstruction, a surgical airway must be established and maintained. Recognition of subtle clinical and physical findings are critical to the diagnosis of laryngotracheal complex injuries and may be life-saving in many instances. To ensure a positive outcome, a strong degree of suspicion based on mechanism of injury is mandated.- - - - - - - - - - ranking = 2keywords = injury (Clic here for more details about this article) |
8/351. Rupture of several parasagittal bridging veins without subdural bleeding.This case reports on a fatal craniocerebral trauma involving numerous ruptured cerebral bridging veins that did not bleed subdurally, despite approximately 15 hours of survival. A 15-year-old girl was severely injured as the passenger of a car that crashed sideways into a tree. She-suffered a cerebral trauma of the "diffuse injury" type and was unconscious after the accident. Her computed tomographic scan at admission showed massive brain edema, axial herniation, and marked hypodensity of the bilateral carotid flow area. Despite intensive care measures, the clinical course was characterized by central decompensation with therapy-resistant cardiocirculatory insufficiency. The autopsy revealed ruptures of numerous parasagittal bridging veins. The injured vessels were not thrombosed, and yet there was absolutely no subdural bleeding. This unusual combination of findings is assumed to be caused by an isolated collapse of cerebral circulation occurring shortly after the accident and primarily attributed to a rapid increase of intracranial pressure.- - - - - - - - - - ranking = 1keywords = injury (Clic here for more details about this article) |
9/351. Traumatic pseudoaneurysm of the abdominal aorta.A traumatic pseudoaneurysm of the abdominal aorta is a rare entity, occurring as the result of a missed aortic lesion at the time of the initial injury. Therefore, clinical suspicion and careful abdominal exploration at first laparotomy is mandatory to prevent aortic pseudoaneurysm formation and its risk of delayed rupture. We present a case of successful surgical treatment of a suprarenal aortic false aneurysm, presenting 4 weeks after a life-threatening gunshot wound in a 13-year-old child.- - - - - - - - - - ranking = 1keywords = injury (Clic here for more details about this article) |
10/351. Total dislocations of the navicular: are they ever isolated injuries?Isolated dislocations of the navicular are rare injuries; we present our experience of six cases in which the navicular was dislocated without fracture. All patients had complex injuries, with considerable disruption of the midfoot. Five patients had open reduction and stabilisation with Kirschner wires. One developed subluxation and deformity of the midfoot because of inadequate stabilisation of the lateral column, and there was one patient with ischaemic necrosis. We believe that the navicular cannot dislocate in isolation because of the rigid bony supports around it; there has to be significant disruption of both longitudinal columns of the foot. Most commonly, an abduction/pronation injury causes a midtarsal dislocation, and on spontaneous reduction the navicular may dislocate medially. This mechanism is similar to a perilunate dislocation. Stabilisation of both medial and lateral columns of the foot may sometimes be essential for isolated dislocations. In spite of our low incidence of ischaemic necrosis, there is always a likelihood of this complication.- - - - - - - - - - ranking = 1keywords = injury (Clic here for more details about this article) |
