OBJECTIVE: Recently, the definition of occult osteoporotic vertebral fracture has been established, and its clinical significance has come to our interest. We report the effect of early percutaneous vertebroplasty in occult osteoporotic vertebral fracture. METHODS: From January 2006 to January 2008, we performed percutaneous vertebroplasty for 50 levels in 47 patients. 21 levels (21 patients) of them were classified into occult osteoporotic vertebral fracture group, 29 levels (26 patients) were categorized into control group (not occult osteoporotic vertebral fracture) by the Pham T..s criteria. We obtained VAS score and measured the compression ratio at first hospital day and 1 day, 1 month, 3 months after procedure. RESULTS: There are noticeable improvements in VAS score. The mean VAS score at admission was 6.44 in occult group and 6.15 in control group, which changed 2.23 in occult group and 2.68 in control group after procedure. The compression rate was 1.008, 1.018, 1.016 in occult group and 0.862, 0.891, 0.881 in control group at admission and 1 month, 3 months after procedure. The conservative effect for vertebral height was higher than control group (p=0.011). CONCLUSION: Percutaneous vertebroplasty in occult osteoporotic compression fracture provided significant pain relief and conservative effect for vertebral height. It is probable that it can lower the rate of secondary adjacent vertebral compression fracture.

Postural reduction was performed in 20 cases of the closed thoracolumbar compression fracture using a soft pillow from January 1982 to June 1985. The results were summarized as following: 1) The compression fracture or mild burst fracture of the thoracolumbar spines can be restored by the postural reduction in hyperextension position using a soft pillow under the back of thoracolumbar junction. 2) The postural reduction resulted in not only expansion of a compressed vertebral body but also successful fusion. 3) It was most satisfactory when the postural reduction was performed as early as possible, at least within 1 week after injury. 4) The postural reduction is considered a simple and convenient treatment of the thoracolumbar compression fracture.

PURPOSE: To differentiate malignant vertebral compression fractures from benign fractures, as seen onspin-echo T1-weighted, fast spin-echo T2-weighted, and fat-suppressed gadolinium-enhanced T1-weighted MR images. MATERIALS AND METHODS: Thirty two benign (18 acute and 14 chronic) and 28 malignant vertebral collapses werestudied in 54 patients aged between 15 and 78 (mean, 51) years. Malignant compression fractures involved onlymetastasis. We obtained sagittal and axial fast spin-echo T2-weighted images, and unenhanced and fat-suppressedgadolinium-enhanced T1-weighted images, and analyzed MR signal intensity, enhancement patterns, and morphologicchanges including convex posterior cortex vs retropulsion of a bone fragment, focal vs diffuse paraspinal mass,and epidural mass. RESULTS: All cases of acute benign and malignant compression fractures showed low signalintensity within the vertebral body on T1-weighted images, and substantial contrast enhancement on fat-suppressedgadolinium-enhanced T1-weighted images. Acute benign and malignant compression fractures were distinguished on thebasis of three signal intensity characteristics: hypointense band (acute benign cases 77% ; malignant cases 0%),diffuse low signal intensity(17% vs 86%) and involvement of pedicle (0% vs 75%). Fast spin-echo T2-weighted imagesplayed little role in distinguishing between the two. Three morphologic changes were suggestive of malignancy:convex posterior cortex (malignant cases 75% ; benign 0%), epidural mass (79% vs 5%), and focal paraspinal mass(57% vs 0%). Retropulsion of a bone fragment (benign cases 63% ; malignant cases 14%) was preferable forbenignancy. in addition, thin diffuse paraspinal mass (benign cases 15% ; malignant cases 14%) was seen.CONCLUSION: The morphologic and signal intensity characteristics seen on T1-weighted images were useful fordistingushing benign and malignant vertebral compression fractures. Fast spin-echo T2-weighted and fat-suppressedgadolinium-enhanced T1-weighted images played little role in distinguishing between the two.
