Abstract:
Objective:To investigate the effect of percutaneous kyphoplasty on the vertebral height and Cobb angle in elderly patients with osteoporotic thoracolumbar compression fractures.Methods:Seventy elderly patients with osteoporotic thoracolumbar compression fractures who were admitted to the Affiliated Hospital of Hubei University of Traditional Chinese Medicine from March 2019 to March 2020 were selected as the study objects. They were grouped according to the random number table method, with 35 patients in each group. The patients in the observation group were treated with multi-point balloon expansion percutaneous kyphoplasty, and the patients in the control group were treated with single balloon expansion percutaneous kyphoplasty. The Visual Analogue Scale (VAS) and Oswestry Dysfunction Index (ODI) score were compared between the two groups before and after treatment. The relative height of injured vertebrae, Cobb angle, bone cement diffusion volume ratio, operation time, radiation exposure time and bone cement injection volume were recorded.Results:There was no significant difference in VAS and ODI score between the two groups before operation (all P>0.05). At 12 months after operation, the VAS and ODI score of the two groups were lower than those before operation (all P<0.05), and the ODI score of the observation group was significantly lower than that of the control group ( P<0.05). At 12 months after operation, the relative height of injured vertebrae in the observation group was higher than that in the control group, and the local Cobb angle was significantly lower than that in the control group (all P<0.05). The total effective rate of the observation group was significantly higher than that of the control group (94.28% vs 82.86%, P<0.05). Compared with the control group, the observation group had higher proportion of grade Ⅱ in the diffusion volume ratio of bone cement and more bone cement injection, and longer operation time (all P<0.05), while there was no significant difference in the radiation exposure time between the two groups ( P>0.05). Conclusions:The treatment of percutaneous kyphoplasty with multi-point expansion of balloon under overextended posture can more effectively improve the relative height of injured vertebrae and improve local Cobb angle of elderly patients with osteoporotic thoracolumbar compression fractures, and does not increase the risk of bone cement leakage. It is worthy of clinical application and promotion.
