This study intends to analyze the causes on poor clinical efficacy of kyphoplasty performed in unilateral transpedicular puncture for the treatment of senile osteoporotic vertebral compression fractures. A retrospective study was conducted on a consecutive series of 70 patients who had underwent kyphoplasty performed in unilateral transpedicular puncture for the treatment of senile osteoporotic vertebral compression fractures between March 2016 to March 2017. These patients were compared for clinical data to investigate the causes on poor clinical efficacy of kyphoplasty performed in unilateral transpedicular puncture for the treatment of senile osteoporotic vertebral compression fractures. Comparison result of the indices between these patients showed that the differences in body weight, fracture type and bone cement dispersion were statistically significant. Logistic multivariate regression analysis showed body weight (OR = 0.892, p = 0.042), fracture type 2 (OR = 0.089, p = 0.020) and bone cement dispersion (OR = 4.773, p = 0.025) are risk factors for poor clinical efficacy. The results of corresponding analysis on VAS (Visual Analogue Scale), vertebral height and Cobb angle in patients with poor clinical efficacy showed that there is a correlation between them. We believe that patients’ weight, dispersion degree of bone cement and fracture type of injured vertebra are the risk factors of kyphoplasty with poor clinical efficacy.
