On the palate, the benign lymphoid hyperplasia report of 1 case R manifestations, combined with related literature can be divided into the following 4 types. 2.1 Pure flexion compression type in 25 cases, plain radiographs showed different degrees of vertebral body anterior wedge deformity, posterior vertebral height is normal, CT prior to vertebroplasty for irregular shaped bone broken line and trabecular bone and vertebral density change, but the posterior vertebral wall integrity. The 2.2 burst fracture in 47 cases, plain radiographs showed the whole vertebral compression becomes flat, the posterior margin of the vertebral body height becomes low, pedicle spacing increases width. Lateral posterior margin of the vertebral body line observation of abnormal changes, it is with pure flexion compression type differential reliable signs, and can judge the degree of stenosis of vertebral body, if the fault disappears, spinal canal stenosis is absolute. CT manifestation of vertebral body was disintegrated, the fracture line relates to the three column and the posterior vertebral wall sheet into the spinal canal, fracture. 2.3 Belt type common in high speed travel process safety belt use sudden deceleration caused by. The stress mainly for lateral buckling shear extreme.Plain films may manifest as fracture line through the transverse process, pedicle, spinous process and vertebral facet joint, interspinous distance increases width, vertebral transverse sections like dehiscence, and posterior vertebral height increase or vertebral posterior width increase. Cr display for the fracture line often involves the posterior column.Flat plate is not easy to display the pedicle fracture for Cr display.But when the transverse fracture line and axial CT scanning plane parallel, often difficult to display. 2.4 Fracture dislocation type 1O cases, this type of stress is more complex, but in flexion rotation and shear interaction occurred, mainly to dislocation associated with avulsion.According to the main sheet type. Plain film and dislocation or subluxation, beats by dre detox, multiple rib fractures of the transverse process, and small articular fracture, vertebral rotation.CT shows the fracture line three column can be involved in any column, vertebral rotation, small joint fracture, dislocation and spinal canal narrowing is blocked or jumping. 3 Discuss 3.1 Classification of spinal injuries according to DesMcMee’s three column theory and Woher classification method, the spinal injury were divided into 4 types: simple buckling type; the burst type; the fracture and dislocation of the safety belt. Three column theory is divided into the spine, three columnar structure, anterior column by the anterior longitudinal ligament and vertebral, disc 2 / 3; in the column for vertebral, disc 1 / 3 and the posterior longitudinal ligament; posterior column of the spinal canal, by laminectomy and accessories and yellow ligament and spine ligament. The classification of Wolter increased spinal involvement degree, which can be more accurately reflect the range of spine injury, fracture displacement and the degree of spinal involvement, to establish a reasonable treatment as well as prognosis is of certain guiding significance. 3.2 Spinal injury X ray plain film diagnosis of conventional X-ray spinal injury as the basic means, its function and value have been known. Cheap, accurate positioning, accept the X-ray dose advantages such as easy to make the patient underwent. Appendix vertebra fracture and dislocation, subluxation in X-ray can clearly display, but in differentiating simple flexion compression fracture and burst fractures sometimes have a certain degree of difficulty. 3.3 CT diagnosis of spinal injury and the value of CT examination of unstable spine injury as well as a radiographic examination after supplementary means for clinical acceptance. CT examination by a 2D image can be displayed clearly fracture details, particularly spinal posterior structure fracture, can observe the morphology and the degree of stenosis of spinal canal.
