Abstract:Objective To investigate the correlation between bone cement dispersion type and recurrent vertebral collapse after vertebroplasty (PVP/PKP) recurrent vertebral collapse after vertebroplasty. Methods Clinical data of 411 patients admitted to Guangdong Province Traditional Chinese Medical Hospital treated with vertebroplasty from April 2009 to May 2016 was analyze retrospectively. Postoperative patients all underwent X-ray examination and were divided into collapse group and non-collapse group according to the follow-up results. Univariate analysis was performed to compare the two groups in terms of gender, age, vertebral compression rate, vertebral height recovery rate, postoperative cobb angle correction value, bone cement injection volume, bone cement dispersion type, bone cement distribution area, and cement leakage. For the differences, Logistic regression analysis was performed. Results All the patients were followed up. The followed up time was from 1 to 37 months with a mean of (17.60±7.28) months. There were 59 cases occured vertebral collapse with the incidence of 14.36%. Vertebral compression rate, the vertebral height recovery rate, bone cement diffusion type, and bone cement leakage were significantly different between the two groups (P < 0.05). The multiple Logistic regression analysis showed that, bone cement with poor dispersion in the fracture line, bone cement with a dense distribution, the vertebral anterior height recovering excessively, PKP were the risk factors for vertebral re-collapse after vertebroplasty (P < 0.01). Conclusion The excessive recovery of the anterior vertebral height, the poor dispersion of bone cement within the fracture line, and the dense distribution of bone cement, PKP are independent risk factors for the recurrence of the vertebral surgery after vertebroplasty.
