Abstract

Abstract:

BACKGROUND: Percutaneous vertebroplasty is an effective method for osteoporotic thoracic vertebral compression fracture, but bone cement leakage is easy to occur in patients with intravertebral cleft.

OBJECTIVE: To explore the therapeutic efficacy of bone-filling mesh containers in elderly patients with osteoporotic vertebral compression fractures combined with intravertebral cleft sign.

METHODS: From October 2017 to July 2018, 62 patients aged from 60 to 80 years with osteoporotic vertebral compression fractures combined with intravertebral cleft sign were admitted at the Affiliated Hospital of Qinghai University. Among them, 31 cases were treated with unilateral percutaneous vertebroplasty (control group), and the other 31 cases were treated with bone-filling mesh containers (study group). The leakage of bone cement, the time of operation and the times of fluoroscopy were recorded in the two groups. The visual analogue scale score and Oswestry disability index score were compared between the two groups before and 7, 30, 60 days after treatment. The height changes of injured vertebrae were evaluated by X-ray before treatment and 7 days after treatment. The quality of life was evaluated by the MOS item short from health survey (SF-36) before and 60 days after treatment.

RESULTS AND CONCLUSION: (1) The time of operation and the times of fluoroscopy in the study group were less than those in the control group (P < 0.05), and the leakage rate of bone cement in the study group was lower than that in the control group (6% vs. 39%, P < 0.05). (2) The visual analogue scale score and Oswestry disability index score of the two groups were significantly improved at 7, 30 and 60 days after treatment. The visual analogue scale scores of the study group were lower than those of the control group at different time points after treatment (P < 0.05). There was no difference in Oswestry disability index scores between the two groups at different time points after treatment (P > 0.05). (3) The height of injured vertebrae 7 days after treatment in both groups was significantly higher than that before treatment (P < 0.05), and there was a significant difference between the two groups (P < 0.05). (4) The quality of life of the two groups was significantly improved at 60 days after treatment (P < 0.05), but there was no difference between the two groups (P > 0.05). These findings indicate that compared with unilateral vertebroplasty with bone cement injection, bone-filling mesh containers with bone cement injection could reduce the incidence of cement leakage, relieve pain and increase the height of injured vertebrae in elderly patients with osteoporotic vertebral compression fracture combined with intravertebral cleft sign.中国组织工程研究杂志出版内容重点：生物材料；骨生物材料; 口腔生物材料; 纳米材料; 缓释材料; 材料相容性；组织工程
