Abstract:
Objective:To explore the clinical efficacy of combined use of artificial bone materials in percutaneous vertebroplasty (PVP) for osteoporotic vertebral compression fractures (OVCF).Methods:One hundred and eighty-four consecutive patients with OVCF admitted to Beijing Friendship Hospital, Capital Medical University from June 2020 to June 2021 were retrospectively analyzed. All patients had single-level fracture and treated with PVP. According to whether artificial bone materials were used, the patients were divided into experimental group ( n=95) and control group ( n=89). The experimental group was treated with bone cement mixed with artificial bone materials, and the control group was treated with bone cement. The following indices were observed in the two groups before surgery and at 3 days, 3 months, 12 months (final follow-up) after surgery: visual analogue scale (VAS) score, Oswestry disability index (ODI), Cobb angle of kyphosis, and the percentage of anterior vertebral height, the amount of bone cement injected, postoperative complications and adjacent vertebral fractures were recorded. Measurement data were expressed as mean±standard deviation ( ± s), and t-test was used for comparison between groups; Chi- test was used for comparison between groups for count data. Results:All patients successfully completed the operation and were followed up for 12-20 months, with a mean follow-up of (14.24±2.51) months. The VAS score at 3 days, 3 months after operation and final follow-up (experimental group: 2.00±0.71, 1.89±0.71, 1.41±0.49; control group: 2.13±0.73, 1.81±0.60, 1.44±0.50) and ODI index at 3 months after operation and the final follow-up [experimental group: (21.56±4.68)%, (23.22±4.11)%; control group: (22.46±3.74)%, (22.39±4.05)%] were significantly improved compared with those before operation [VAS, experimental group: 7.66±0.86, control group: 7.81±0.89; ODI, experimental group: (70.11±8.24)%, control group: (68.97±8.59)%], and the differences were statistically significant ( P<0.05). There were no significant differences in the amount of bone cement injected between the two groups ( P>0.05). There was no significant difference in the Cobb angle of kyphosis and the percentage of anterior vertebral height at each time point ( P>0.05). The incidence of bone cement leakage in the experimental group was 15.8% (15/95), slightly lower than that in the control group [22.5% (20/89)], but the difference was not statistically significant ( P>0.05). As of the final follow-up, the incidence of adjacent vertebral fracture in the experimental group was 8.4% (8/95), which was lower than that in the control group (19.1%, 17/89), and the difference was statistically significant ( P< 0.05). Conclusion:The application of bone cement mixed with artificial bone materials in PVP for OVCF, can achieve good clinical efficacy, and reduce the incidence of adjacent vertebral fractures.
