Skiing and snowboarding are popular winter sports associated with significant traumatic spinal injuries. Despite a decline in most injuries related to these sports over the years, acute injury rates of the spine have remained stable and even increased. Vertebral fractures and spinal cord injuries are the most common serious acute injuries of the spine in skiers and snowboarders. Due to the unique characteristics of each sport, different injury mechanisms are responsible for the majority of injuries. This article reviews injury patterns, injury types, mechanisms of injury, and strategies for prevention of spine injuries in skiers and snowboarders. 相似文献

Malalignment of the vertebrae, in patients suspected of blunt spinal trauma, is the quintessential sign of spinal injury. Malalignment is obvious in displaced fractures and dislocations but is rarely considered in the diagnosis because of the obvious injury. In patients with more subtle injuries such as those limited to ligamentous structures, vertebral malalignment is the only radiographic sign that leads one to the recognition of the injury. Equally important is the fact that vertebral malalignment may be congenital and may be due to physiologic movement as well as radiographic patient positioning. Recognition of the pattern of traumatic malalignment as distinguished from the appearance of non-traumatic malalignment is essential to accurate radiologic diagnosis. Because malalignment is critical to the radiographic assessment of blunt cervical spine injury, this presentation is limited to the cervical spine. The format of the article includes signs of physiologic and traumatic malaignment as seen on antero-posterior and lateral radiographs of the cervico-cranium and the lower cervical spine. 相似文献

Imaging in spinal trauma 总被引:1,自引:0,他引:1
Because it may cause paralysis, injury to the spine is one of the most feared traumas, and spinal cord injury is a major cause of disability. In the USA approximately 10,000 traumatic cervical spine fractures and 4000 traumatic thoracolumbar fractures are diagnosed each year. Although the number of individuals sustaining paralysis is far less than those with moderate or severe brain injury, the socioeconomic costs are significant. Since most of the spinal trauma patients survive their injuries, almost one out of 1000 inhabitants in the USA are currently being cared for partial or complete paralysis. Little controversy exists regarding the need for accurate and emergent imaging assessment of the traumatized spine in order to evaluate spinal stability and integrity of neural elements. Because clinicians fear missing occult spine injuries, they obtain radiographs for nearly all patients who present with blunt trauma. We are influenced on one side by fear of litigation and the possible devastating medical, psychologic and financial consequences of cervical spine injury, and on the other side by pressure to reduce health care costs. A set of clinical and/or anamnestic criteria, however, can be very useful in identifying patients who have an extremely low probability of injury and who consequently have no need for imaging studies. Multidetector (or multislice) computed tomography (MDCT) is the preferred primary imaging modality in blunt spinal trauma patients who do need imaging. Not only is CT more accurate in diagnosing spinal injury, it also reduces imaging time and patient manipulation. Evidence-based research has established that MDCT improves patient outcome and saves money in comparison to plain film. This review discusses the use, advantages and disadvantages of the different imaging techniques used in spinal trauma patients and the criteria used in selecting patients who do not need imaging. Finally an overview of different types of spinal injuries is given. 相似文献

Is there an association between fractures of the cervical spine and first- and second-rib fractures?
P M Logan 《Journal l'Association canadienne des radiologistes》1999,50(1):41-43
OBJECTIVE: To investigate a potential association between cervical spine injury and first- and second-rib fractures. METHODS: Retrospective review of the radiologic and medical records of 28 consecutive patients admitted to an acute spinal injury unit. RESULTS: A total of 10 (36%) of the patients with cervical spine trauma also had fractures of either the first or second ribs. Eight of these 10 patients had a fracture or fracture-subluxation of the seventh cervical vertebra or the C6/7 segment. CONCLUSION: Almost one-third of patients with traumatic cervical spine injury have an associated upper-rib fracture. The strongest association is between injury at the C7 level and first-rib fracture. 相似文献

INTRODUCTION: Disability following traumatic spine injury often requires assessment for judicial reasons. OBJECTIVE: To determine the optimum time to carry out a medico-legal evaluation. METHODS: Retrospective study (1995-2000) of patients with traumatic spine injury with a follow-up of five years. The American Spinal Injury Association (ASIA) scale was used to determine level and extent of the injury. Statistical analysis by SPSS 11.0. RESULTS AND DISCUSSION: 173 injuries were analyzed (39.3% ASIA A; 15.6% ASIA B; 29.47% ASIA C; 15.6% ASIA D). Neurological improvement was detected in 35.83%, more frequently in incomplete injuries. ASIA A injuries remained mainly complete from admission to discharge and in no case reached functional levels. Only a third of ASIA B patients showed improvement, of whom 33.3% were functional. Improvement in ASIA C patients was 76.4%, these and all ASIA D patients were functional on discharge. The condition a year after the injury remained unchanged in all cases, regardless of the extent of injury. Patients who showed improvement did so early on, mainly during hospitalization. CONCLUSIONS: The optimum time for evaluation of spinal cord injury for medicolegal purposes is at one year after the injury. In cases of complete injury, evaluation can be carried out on discharge with no need to wait for one year. 相似文献

Cervical spine trauma can clearly result in neurologic injury. An unusual traumatic event is a vascular insult of the vertebral arteries, potentially leading to stroke. The vertebral arteries are vulnerable to compression at several sites in the cervical spine. The high degree of physiologic rotation at the atlanto-axial joint places the vertebral artery at risk through normal daily activities as well as following forceful trauma, including manipulative treatment. Cerebrovascular insufficiency is an uncommon but serious complication of cervical spinal manipulation, which can lead to posterior circulatory impairment. Comprehensive diagnostic studies may be required to differentiate primary intracranial pathology from cerebral symptoms secondary to vascular compromise. 相似文献

The general incidence of skiing and snowboarding injuries is decreasing in the last years. But there is some evidence that rare severe injuries like traumatic brain injury and spinal cord injury are increasing. Higher speed, extreme acrobatic forms of sport practice and increased risk taking behavior are discussed as possible reasons. Information about the risk and the sequelae of spine injuries should be placed in the first place. The spine protectors available on the market deliver only protection in specific situations. 相似文献

The results of a computer analysis of 399 patients with documented fractures and/or dislocations of the cervical spine are summarized. Vertebral arch fractures were present in half of all patients with radiographic evidence of cervical spine trauma. Two-thirds of the patients had two or more injuries. Isolated disk injuries were rare and, when present, were characterized by a vacuum sign. The dens fracture, with or without atlantoaxial dislocation, was rarely associated with injury elsewhere in the cervical spine. The study suggests that the routine five-film cervical spine examination is inadequate to detect the most common traumatic lesions. Thus vertebral arch views (pillar views) should be obtained if there is evidence to suggest hyperextension as the mechanism of injury. In addition, the study underscores the importance of aggressively searching for multiple abnormalities. 相似文献

OBJECTIVE. Our prior experiments suggested that traumatic laceration of the aorta induced by rapid deceleration results from pinching of the aorta between the spine and the anterior bony complex (manubrium, clavicle, and first rib). This study examines that hypothesis with in vivo CT data. MATERIALS AND METHODS. In 22 patients with angiographically and surgically proved lacerations of the proximal descending aorta, chest CT scans were obtained before (18) or after (four) surgical repair. The point of impact of the anterior bony complex with the anterior surface of the thoracic spine during compression of the thorax was predicted by simulated rotation of the first rib based on calculations made from the CT scans. RESULTS. In all 22 patients, the projected site of impact of the anterior bony complex with the spine corresponded to the actual injured aortic segment as determined with angiography. CONCLUSION. Our data further support the proposed "osseous pinch" mechanism of injury to explain traumatic tears of the aorta. 相似文献

A rare case of traumatic injury of the distal descending aorta associated with thoracic spine injury is reported. A 21-year-old
man was admitted after a traffic accident. Thoracic CT and angiography demonstrated a false aneurysm of the distal descending
aorta and a compression fracture of the eleventh thoracic vertebra. At emergency surgery, a transverse linear tear at the
level of the aortic hiatus was confirmed and repaired.

Parachuting is a unique method of deploying troops. Accidents in parachuting are common, but usually carry minimal risk for severe injury. Most accidents occur during landing and injuries often affect the lower limbs and spine. Traumatic amputation of a limb is an extremely rare event in parachuting. We present a case of a parachutist who suffered a traumatic amputation of the left hand during jumping off the plane. 相似文献

Radiology of the cervical spine in trauma patients: practice pitfalls and recommendations for improving efficiency and communication 总被引:1,自引:0,他引:1

Trauma constitutes a significant portion of emergency department practice. Such patients often have suspected cervical spine injury necessitating cervical spine radiographs. The importance of detecting cervical spine injury is obvious because failure to do so can lead to tragic consequences for patient and physician alike. Although most cervical spine radiographs are justified, poorly indicated and unnecessary examinations are unfortunately commonplace. Indiscriminate ordering of cervical spine examinations can easily exceed radiology resources assigned to the emergency department. Rational ordering practices are therefore essential for efficient patient management. A risk-tailored approach to performing these examinations, which can improve efficiency, is presented. Once obtained, cervical spine radiographs are presumed to detect injury with consistently high sensitivity. Prevailing conditions of emergency department practice that may lower the "sensitivity" of cervical spine radiographs are reviewed. Overreliance on the initial radiologic examination may lead to inappropriate haste in the evaluation of suspected cervical region injury as exemplified by the commonly voiced mandate to "clear the cervical spine" of injury. This approach is discouraged in patients with significant trauma in favor of a careful, progressive evaluation of the potentially injured cervical spine. Periodic review of these complex issues and close cooperation between clinical services are emphasized. 相似文献

MR imaging was found to be the most sensitive modality for the detection of spinal cord abnormalities in the acutely injured spine. Although it is reported that traumatic pneumomyelogram indicates a base-of-skull or middle cranial fossa fracture and is almost certainly associated with intracranial subarachnoid air, early MR imaging may demonstrate subarachnoid air in penetrating trauma of the spinal cord without head injury. We report two cervical-spine stab-wound cases, one of which had subarachnoid air on early MR findings. 相似文献
