![]() most pts can be treated symptomatically w/ short period of bed rest until pain is diminished non operative treatment remains the standard for compression fx many of these problems are overcome by frontal & sagittal reformation. minimal vertebral body compression fractures may be missed disadvantage of axial CT is its inability to detect subtle horizontally oriented fractures of the vertebral bodies, pedicles, or lamina visualizes spinal canal, degree of neural compromise, and delineates element involvement, particularly in a burst fracture allows good visualization of the posterior elements, which is necessary inorder to rule out the possibility of Chance fracture amount of anterior compression should be no more than 40 % (relative to posterior vertebral body height (otherwise a burst frx may be present) there is no anterior or posterior translation of the vertebral bodies anterior ht of vertebra body is diminished, while posterior ht remains nl radiographs: (see radiographs for burst frx) in some cases there may be disruption of posterior column in tension, as upper segments hinge forward on middle column middle column remains intact & may act as hinge compression frx result from anterior or lateral flexion causing failure of the anterior column Type D - buckling of anterior cortex w/ both end plates intact Type B - involvement of superior end plate Type A - involvement of both end plates 4 types of compression frx according to Denis classification a good quality AP radiograph may help rule out compression frx (absence of posterior element frx) be suspicious of "compression" fractures in young patients involved in MVA these frx are normally stable (assumming the dx is correct) & rarely involve neurologic comprimise ![]() determine whether the frx is stable or unstable Back pain and vertebral crush frxs: an unemphasized mode of presentation for primary hyperparathyroidism.
