Abstract:
Objective:To investigate the value of magnetic resonance imaging, CT and X ray radiography on preoperative diagnosis of osteoporotic vertebral compression fracture and post-operation follow up of percutaneous kyphoplasty.Methods: A retrospectively analysis was adopted for 41 patients of osteoporotic vertebral compression fracture, who were detected by X ray, MRI examination and CT analyze, respectively. And the values of 3 methods for preoperative diagnosis of osteoporotic vertebral fractures and X-ray in postoperative follow-up were analyzed. Results: For preoperative diagnosis of osteoporotic vertebral compression fractures, the accuracy rate of MRI, X-ray and CT were 100%(41/41), 65.85%(27/41) and 92.85%(13/14), respectively. Both of the accuracy rates of MRI and CT were higher than X-ray, and the differences were statistical significant (x2=16.882,x2=3.837;P<0.05); the difference of accuracy rate between MRI and CT was not significant (x2=2.983,P>0.05). After the third day of post-operative and during last follow up, anterior vertebral height and middle vertebral height were significantly higher than before operation (F=17.094,F=15.526,P<0.05); and the Cobb angle and the VAS score of lumbar back pain were lower than before operation, the difference was statistical significant (F=41.085,F=107.338;P<0.05).Conclusion: For preoperative diagnosis of osteoporotic vertebral compression fractures, the accuracy rate of MRI is the highest and X-ray is lowest. X-ray can be used to evaluate surgery effect during postoperative follow-up.
