Balloon kyphoplasty combined with bone cement for the treatment of osteoporotic vertebral fracture in 58 cases / 中国组织工程研究

ABSTRACT

OBJECTIVE: To investigate the effect of balloon kyphoplasty combined with bone cement on the treatment osteoporotic vertebral fracture.METHODS: A total of 58 aged patients with single osteoporotic vertebral compression fracture (58 vertebral bodies) were treated with balloon kyphoplasty. The fracture always occurred at T_8-L_4 segment of vertebral body in particular at T_(10)-L_2 segment of thoracic waist. By local anesthesia, lateral or bilateral pedicle of vertebral arch was punctured to injection bone cement under C-arm fluoroscopy.RESULTS: Bone cement leakage occurred in 8 cases, including leakage along posterior longitudinal ligament into adjacent posterior margin of vertebral body (n=1), external edge of vertebral body (n=6), and subcutaneous tissue (n=1); however, all the patients did not have clinical symptoms. C-arm fluoroscopy showed that height of vertebral body was increased, and rachiokyphosis was improved after treatment. Pain was obviously improved, and the easement rate of pain was 100%. There was significant difference in visual simulation score, angle degree of rachiokyphosis, and living activity scale before and 6 months after treatment (P < 0.05), but there was no significant difference between 6 months after treatment and following up stopping (P>0.05).CONCLUSION: Balloon kyphoplasty can significantly ease pain caused by osteoporotic spinal fractures and tumor metastatic spinal fractures and can partially restore vertebral body height and kyphosis deformity, there is conducive to improving spinal function and improving the quality of life.
