Bone cement injection as vertebral augmentation therapy for osteoporotic vertebral compression fractures / 中国组织工程研究

ABSTRACT

BACKGROUND:Vertebroplasty with bone cement injection can achieve a correction of kyphosis, enhancement of vertebral strength, and elimination of vertebral lesions during reduction of the fracture. OBJECTIVE: To analyze the efficacy of vertebroplasty with bone cement injection on osteoporotic vertebral compression fracture. METHODS:Totaly 84 patients with osteoporotic thoracolumbar vertebral compression fractures (T6-L4), 37 males and 47 females, aged 58-80 years, were randomized into two groups study group undergoing vertebroplasty with bone cement injection and control group subject to bed rest and conservative treatment (functional exercise of the back muscle). Visual analog scale score, Oswestry disability index and vertebral height were detected and compared between the two groups before and after treatment. RESULTS AND CONCLUSION:There was no difference in vertebral height, visual analog scale score and Oswestry disability index between the two groups before treatment. At 3 months after treatment, the vertebral height was (1.653±0.168) cm in the study group and (1.521±0.200) cm in the control group, with a significant difference (P 0.05). These findings suggest that the bone cement injection as vertebral augmentation therapy can rapidly relieve pain, improve patients' quality of life within a short term and restore the vertebral height in patients with osteoporotic vertebral compression fractures.
