| Objective To clarify whether percutaneous curved vertebroplasty (PCVP) is superior to percutaneous vertebroplasty (PVP) in terms of vertebral morphology and cement diffusion degree in elderly patients with osteoporotic vertebral compression fractures.Methods The clinical data of 125 patients with single segment osteoporotic vertebral compression fractures treated in Taiyuan City Center Hospital from June 2022 to January 2024 were retrospectively analyzed. Of these patients, 80 patients opted for PCVP treatment (PCVP group) and 45 patients opted for bilateral PVP treatment (PVP group). The operation time, number of fluoroscopies, and bone cement injection volume were compared between the two groups, as were the compression ratio of the injured vertebrae, Cobb angle, percentage of vertebral height, anterior vertebral height, VAS score, and bone cement dispersion type ratio six months after the operation.Results The average follow-up time of the two groups was (6.72±0.67) months. Compared with the PVP group, the PCVP group showed greater advantages in terms of operation time, X-ray fluoroscopy times, and bone cement injection volume; these differences were statistically significant (P<0.05). The PCVP group had better postoperative clinical recovery in terms of the compression ratio of injured vertebrae compared with the PVP group (P<0.05). Six months after the operation, the Cobb angle, height percentage, and anterior vertebral height of the injured vertebrae in the PCVP group and PVP group had significantly improved (P<0.05), but there was no significant difference between the two groups (P>0.05). The VAS scores in the PCVP group and PVP group were (8.35±1.01) scores and (8.38±1.02) scores preoperatively, and (1.46±0.66) scores and (2.18±0.89) scores at 6 months post-operatively. These scores were significantly improved compared to pre-operative scores (P<0.05). However, the PCVP group had a better score than the PVP group at 6 months post-operatively (P<0.05). The proportion of bone cement dispersion types in the PCVP group was better than that in the PVP group (P<0.05), and the bone cement dispersion was more extensive.Conclusion PCVP and bilateral PVP can significantly reduce pain in the treatment of vertebral compression fractures caused by osteoporosis. There is no significant difference in postoperative clinical efficacy or vertebral morphology between the two groups. However, due to the shorter operation time, reduced bone cement injection and improved diffusion effect in the PCVP group, this method is more suitable for elderly patients who cannot tolerate the long-term prone position. |
