Background Percutaneous vertebroplasty related postoperative secondary fractures risk factors were not consistent in patients with osteoporotic vertebral compression Fractures. The purpose was to identify the risk factors of the secondary fractures for osteoporotic vertebral compression fractures after percutaneous vertebroplasty.
Methods Potential academic articles were identified from Cochrane Library, Medline, PubMed, Embase, ScienceDirect and other databases. The time range we retrieved from was that from the inception of electronic databases to August 2019. Gray studies were identified from the references of included literature reports. STATA version 11.0 (Stata Corporation, College Station, Texas, USA) was used to analyze the pooled data.
Results Fourteen studies involving 1910 patients, 395 of whom had secondary fracture following the surgery were included in this meta-analysis. The results of meta-analysis showed the risk factors of the secondary fractures for osteoporotic vertebral compression fractures after percutaneous vertebroplasty was related to bone mineral density [WMD= -0.518, 95%CI(-0.784,-0.252), P=0.000], cement leakage [RR=0.596, 95%CI (0.444,0.798), P=0.001] and kyphosis after primary operation [WMD=4.510, 95%CI (3.061,6.004),P=0.000], but not to gender, age, body mass index (BMI), cement volume, thoracolumbar spine, and cement injection approaches.
Conclusions BMD, cement leakage and kyphosis after primary operation are the risk factors closely correlative to the secondary fracture after percutaneous vertebroplasty. There has not been enough evidence to support the association between the secondary fracture and gender, age, body mass index, cement volume, thoracolumbar spine, and cement injection approach.
