Percutaneous kyphoplasty with bone cement injection rapidly eases pain in patients with multi-segmental thoracolumbar vertebral osteoporotic fractures / 中国组织工程研究

ABSTRACT

BACKGROUND:Percutaneous kyphoplasty with bone cement injection for repair of multi-segmental thoracolumbar vertebral osteoporotic fractures can restore the compressed vertebral height, correct deformity and reduce complications. OBJECTIVE: To explore the therapeutic effects of percutaneous kyphoplasty with bone cement in patients with multi-segmental thoracolumbar vertebral osteoporotic fractures. METHODS:Eighty patients with multi-segmental thoracolumbar vertebral osteoporotic fractures were enroled, 29 males and 51 females, aged 61-78 year, including 52 case of two-segmental vertebral fractures, 22 cases of three-segmental vertebral fractures, 6 cases of four-segmental vertebral fractures. Al the patients were divided into experimental group and control group randomly. Patients in the control group were given active basic treatment and anti-osteoporosis treatment and stayed in bed. Patients in the experimental group were given percutaneous kyphoplasty with bone cement injection on the above basis. Al the patients were folowed-up 12 months after treatment. Then the Oswesty dysfunction index, Barthel index, visual analog scale score, and theanterior vertebral height and midline height, Cobb angle were compared between the two groups. RESULTS AND CONCLUSION: In the experimental group, the Oswesty dysfunction index, Barthel index, visual analog scale score, and the anterior vertebral height and midline height, Cobb angle were al significantly improved at 3 days, 3 months and 12 months after treatment than before (P < 0.05). In the control group, the Oswesty dysfunction index, Barthel index and visual analog scale score were improved significantly at 3 and 12 months after treatment (P < 0.05), while the anterior vertebral height and midline height were improve dramaticaly at 12 months after treatment (P < 0.05). Compared with the control group, the experimental group showed better the Oswesty dysfunction index and Cobb angle than the control group at 12 months after treatment (P < 0.05), but there were no difference in the other indicators between the two groups. No adverse reactions associated with bone cement material occurred in the experimental group. Taken together, the percutaneous kyphoplasty with bone cement injection can rapidly relieve pain in patients with multi-segmental thoracolumbar vertebral osteoporotic fractures, which can correct kyphosis and improve patient's quality of life.
