Comparison of percutaneous vertebroplasty and percutaneous curved vertebroplasty for osteoporotic vertebral compression fractures: Distribution and leakage rate of injected bone cement / 中国组织工程研究

ABSTRACT

BACKGROUND: Percutaneous curved vertebroplasty is a modified surgical method of percutaneous vertebroplasty; the most prominent feature of which is that it can make the bone cement distributed symmetrically and balance the strength on both sides of the vertebral body. In theory, it can ensure the distribution of bone cement in the vertebral body, and solve the problem that the uneven distribution of bone cement in the traditional percutaneous vertebroplasty and single injection leads to poor pain relief effect in the fracture area. OBJECTIVE: To compare the clinical efficacy of percutaneous curved vertebroplasty and percutaneous vertebroplasty bone cement injection in the treatment of osteoporotic vertebral compression fractures, and to discuss the value of percutaneous curved vertebroplasty in clinical application. METHODS: Seventy patients with single vertebral osteoporotic vertebral compression fractures from the Third Affiliated Hospital of AnHui Medical University between 2017 and 2018 were selected. The patients were randomly divided into two groups. Percutaneous curved vertebroplasty group (n=35) received treatment with percutaneous curved vertebroplasty. Percutaneous vertebroplasty group (n=35) received treatment with percutaneous vertebroplasty. Distribution and leakage of bone cement were observed in the two groups. Visual analogue scale score and Oswestry disability index were assessed preoperatively and 1 day postoperatively. Postoperative follow-up was conducted for 1 year to observe the recovery of the height of the anterior edge of the injured vertebra and the occurrence of adjacent vertebral fractures. The trial was approved by the Ethics Committee of the Third Affiliated Hospital of Anhui Medical University. RESULTS AND CONCLUSION: (1) Compared with the percutaneous vertebroplasty group, the distribution of bone cement was more uniform and satisfactory (P0.05). (4) There was no significant difference in the incidence of adjacent vertebral fractures between the two groups (P>0.05). (5) The results showed that compared with the treatment of percutaneous vertebroplasty, the treatment of osteoporotic vertebral body compression fractures by percutaneous curved vertebroplasty can reduce the rate of bone cement leakage and improve the quality of life of patients.
