The visual analogue scale, vertebral body height, Cobb angle, CT values pre-operation and post-operation as well as incidence of complications were observed. All the patients were successfully followed up with an average period of 11.3\u2009months (ranging from 6 to 12\u2009months). The patients could ambulate on the second day after the operation. The visual analogue scale scores significantly decreased from two\u2009days after the operation to the last follow-up compared with that before the operation ( p\u2009&lt;\u20090.05); the average vertebral height and local Cobb angle had significant recovery ( p\u2009&lt;\u20090.05); the CT value of the treated vertebra significantly increased compared with that before the operation ( p\u2009&lt;\u20090.05). Bone cement leakage occurred in one case, anterior edge leakage occurred in one case, and no clinical symptoms caused by bone cement leakage occurred. No re-fracture of the treated vertebral body or adjacent vertebral bodies were observed in the follow-ups. With good osteogenic activity and degradable absorption characteristics, mineralized collagen was compounded with the existing polymethyl methacrylate bone cement to reduce its strength in the vertebral body and enhance biocompatibility, the incidence of adjacent vertebral fractures and re-fractures within the injured vertebrae is significantly reduced, and good clinical results are obtained, which is worthy of popularization.<\/jats:p>","DOI":"10.1177\/0885328221990821","type":"journal-article","created":{"date-parts":[[2021,2,11]],"date-time":"2021-02-11T18:16:55Z","timestamp":1613067415000},"page":"1366-1371","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":1,"title":["The
