Abstract: Objective To explore and analyze the application value of low-dose CT scanning in CT guided vertebroplasty. Methods From January 2022 to December 2022, 108 cases of patients with osteoporotic vertebral compressibility fracture (OVCF) who were diagnosed and treated in Yuzhong County Hospital of Traditional Chinese Medicine, Lanzhou, Gansu were selected as the study subjects. Accorded to the random number table method, the patients were divided into 54 cases in study group and 54 cases in control group. The control group were received traditional digital X-ray imaging localization guidance, while the study group were received low-dose CT scanning localization guidance, and both groups were received percutaneous vertebroplasty (PVP) treatment. All the prognosis of the two groups of patients were recorded and compared. Result The differece between the pain VAS score at 7 days after the surgery and the score at the day before the surgery in either group of patients was statistically significant (P<0.05), with the former lower than the latter. And the lumbar ODI, Cobb angle were different in both groups from the day before and 3 months after the surgery, and these indicators were also significantly different between groups at 3 months after the surgery(P<0.05), with the former lower than the latter. The success rates of puncture by a one-time attempt were 98.15% vs. 83.33% in study group and control group, respectively(P<0.05). The amount of cement injection and cement leakage in study group were significantly lower than those in control group (P<0.05). Conclusion The application of low-dose CT scanning in CT guided vertebroplasty can improve the success rate of puncture by a one-time attempt, reduce the amount of bone cement injection and leakage in patients, promote pain relief, improve lumbar function, and reduce Cobb angle.
