- PURPOSE
To find out the relationship between the initial Magnetic Resonance Image (MRI) findings and the progression of vertebra collapse when treated with Jewett brace in osteoporotic stable thoracolumbar fractures.
MATERIALS AND METHODS
We divided 38 cases of 37 patients of thoracolumbar osteoporotic stable thoracolumbar fractures who were treated with Jewett brace into two groups. One group was composed of those body collapse progressed more than 10% compared with the initial state, and the other group less than 10%. We analyzed the relationships between the progression of collapse and the superior endplate fractures, the fracture line extending to posterior cortex, the size of bone marrow edema, the signal intensity on T1 and T2 weighted MR images, the presence of paravertebral hematoma, and the degree of posterior extensor muscle atrophy using MR images.
RESULTS
The body collapse was more likely to progress when there was superior endplate fracture, when it showed larger size of bone marrow edema on T1 weighted image, and transverse low signal on T2 weighted image. But extending of fracture line to posterior cortex, presence of paravertebral hematoma, and degree of posterior extensor muscle atrophy did not show any statistical correlations to progression of collapse.
CONCLUSION
The body collapse is more likely to progress when there was superior endplate fracture, larger low signal on T1 weighted image and low signal on T2 weighted image at initial MRI treated with Jewett brace.

- PURPOSE
To study which factors affect the deformity correction of vertebral body during kyphoplasty procedure.
MATERIALS AND METHODS
25 osteoporotic vertebral compression fractures were treated with balloon kyphoplasty from October 2006 to May 2007. Lateral radiographs were taken at 5 different stages with preoperative lateral decubitus position, after placing the patient in prone position on an operation table, after inflating balloon, after deflation and removal of the balloon, after inserting the cement. Then we analyzed the compression ratios and kyphotic angles of the vertebral bodies in each stage.
RESULTS
Placing the patient in prone position showed significant postural reduction in kyphotic angle and restorement of the anterior and middle body height. The inflation of the balloon demonstrated significant reduction of kyphotic angle and restorement of the anterior and middle body height. After the deflation, anterior and middle body height has decreased significantly. After the deflation, the kyphotic angle and the anterior and middle body heights were not restored signigicantly compared with those of initial prone position.
CONCLUSION
Vertebral height and kyphotic angle were partially recovered by inflating the balloon, but the correction was lost after deflating the balloon. Statistically, the body deformity was not restored significantly after deflating the balloon compared with that of intraoperative prone position. Therefore, we concluded that, in kyphoplasty of osteoporotic compression fractures, the postural reduction is the most important factor in deformity correction of fractured vertebral bodies.
