Abstract:

BACKGROUND: Vertebroplasty is one of the effective methods for minimally invasive treatment of osteoporotic vertebral compression fractures. Bone cement as the most commonly used filling material is disputed on its clinical effects of different viscosity.

OBJECTIVE: To compare the efficacy and safety of different viscosity bone cement vertebroplasty in the treatment of osteoporotic vertebral compression fractures.
METHODS: One hundred and eighty-three patients with osteoporotic vertebral compression fracture were randomly divided into four groups: percutaneous vertebroplasty with high viscosity bone cement group (group A), percutaneous vertebroplasty with low viscosity bone cement group (group B), percutaneous kyphoplasty with high viscosity bone cement group (group C), and percutaneous kyphoplasty with low viscosity bone cement group (group D).

RESULTS AND CONCLUSION: (1) The operative time and X-ray exposure time were longer in the two low viscosity bone cement groups than the two corresponding high viscosity bone cement groups, respectively. (2) After operation, visual analogue scale scores and disability index scores were gradually decreased in the all the groups. Compared with the group A, the visual analogue scale score and disability index score were lower in the group C; compared with group B, the visual analogue scale score and disability index score were lower in the group D. (3) After operation, the kyphosis Cobb angle was gradually reduced and the sagittal index of injured vertebrae were gradually increased in all the groups. The postoperative Cobb angle value was ranked as follows: group A > group C > group D. (4) Compared with two low viscosity bone cement groups, two high viscosity bone cement group had lower incidence of adverse events. These findings indicate that high viscosity bone cement has better safety and effectiveness in the treatment of osteoporotic vertebral compression fractures. The clinical efficacy of percutaneous kyphoplasty with high viscosity bone cement is the best among the four systems.
