Different bone cement implantation ways for osteoporotic vertebral compression fractures

doi:10.3969/j.issn.2095-4344.2017.14.003

Abstract

Abstract:

BACKGROUND: After the treatment of osteoporotic vertebral compression fractures with bone cement implantation, deteriorative osteoporosis and the distance augment between bone cement and bones result in a decrease in bone cement-bone interface compression strength and torsion strength, and then the bone cement tends to displace, which is easy to cause a secondary vertebral fracture.
OBJECTIVE: To investigate the clinical efficacy of bone cement implantation via three approaches on osteoporotic vertebral compression fractures.
METHODS: Sixty patients with single osteoporotic vertebral compression fracture were treated with vertebroplasty, percutaneous kyphoplasty or fraction cement vertebroplasty. All data were collected to analyze the correlation between the bone cement morphology and treatment method, and to detect the visual analogue scale, Oswestry disability index, Cobb angle and incidence of secondary vertebral fractures.
RESULTS AND CONCLUSION: The visual analogue scale scores, Oswestry disability index, and Cobb angle in the three groups were significantly improved after treatment (P < 0.05). All above indicators showed no significant difference among groups at each time point after treatment, suggesting that these three kinds of treatments exert the same effects on pain relief, functional recovery, preventing the vertebral height loss and maintaining spinal mechanical properties. Bone cement displacement and secondary vertebral fracture occurred after clotted cement implantation. Therefore, mixed and trabecular-shaped grafts are preferred, aiming to achieve good long-term treatment outcomes in osteoporotic vertebral compression fractures.
