ABSTRACT
OBJECTIVE@#To explore the clinical effects of bone filling bag vertebroplasty in treating osteoporotic vertebral compression fractures.@*METHODS@#The clinical data of 127 patients (145 vertebrae) with osteoporotic vertebral compression fractures who corresponded the criteria of inclusion and exclusion from December 2015 to June 2017 were retrospectively analyzed. Responsible vertebral bodies were identified by clinical situation, X-rays, CT scan, MRI. Among them, 95 cases (110 vertebrae) were treated by percutaneons kyphoplasty (PKP group), there were 34 males (42 vertebrae) and 61 females (68 vertebrae), with an average age of (73.92±7.14) years, 47 thoracic vertebra (T₈-T₁₂) and 63 lumbar vertebra (L₁-L₅). Other 32 patients (35 vertebrae) were treated by bone filling bag vertebroplasty(bone filling bag vertebroplasty group). There were 11 males (12 vertebrae) and 21 females (23 vertebrae), with an average age of (71.56±7.89) years, 16 thoracic vertebra (T₉-T₁₂) and 19 lumbar vertebra(L₁-L₅). Postoperative pain after 3 days, vertebral body height, improvement of lumbar function were recorded and bone cement diffusion and leakage were observed by X-rays.@*RESULTS@#All operations were successful and no complications were found. In bone filling bag vertebroplasty group, operation time was (31.75±4.99) min, postoperative VAS score at 3 days was(2.38±0.94) points, anterior and middle height of the vertebral body were(19.54±2.36) mm and (18.16±2.65) mm, respectively; ODI score was(25.19±5.49) points, all above items after operation were better than preoperation(0.05). Bone cement was patchy, clumpy or slightly dispersed by X-rays at 3 days after operation, the leakage rate of bone cement in bone filling bag vertebroplasty group was 2.86%(1/35), while was 6.36%(18/110) in PKP group, all of them were "trailing sign", there was significant difference between two groups (<0.05).@*CONCLUSIONS@#The clinical effect of bone filling bag vertebroplasty in the treatment of osteoporotic vertebral compression fractures is similar to percutaneous kyphoplasty, it can effectively relieve the pain, restore part vertebral body height and obviously reduce the leakage rate, with safer, it is a simple, rapid and effective therapeutic method.
