Abstract:
Objective To investigate the morphological charcteristics of compressive fractures in different spinal segments．Methods 412 cases of patients with 448 wedge and burst thoracic and lumbar fractures were analysed for comparison of the incidence of wedge and burst fractures in different segments，and to calculate compression rate of anterior height of verterbral body to posterior height for burst fracture in every segment．Results The incidence of wedge fractures in the middle and lower thoracic spine was comparatively high while during the occurrence of burst fractures in the thoracic segments the ratio between the compression ratio of the anterior and posterior height is comparatively high．In the lumbar spine，especially in the lower lumbar，the incidence of burst fractures was higher than other segments．The compression ratio for burst fracture in the middle and lower thoracic spine was bigger while the compression rate for wedge fracture in the lumbar spine，especially in the lower lumbar in comparison with the thoracic segments，was smaller． Conclusion Besides the external violence force and the posture of the patient at the moment of injury，the type or morphologic characteristics of spine fracture is also related to the spinal segments where the fractures take place．
