Abstract:
Objective:To analyze the safety and efficacy of single percutaneous vertebroplasty (PVP) in the treatment of multi-segment osteolytic spinal metastases.Methods:A retrospective analysis was conducted on 113 patients with multi-segment osteolytic spinal metastases treated with PVP at Beijing Friendship Hospital, Capital Medical University from January 2013 to December 2019, including 50 males and 63 females. The age ranged from 47 to 85 years, with a mean of (66.9±1.52) years. Patients were divided into two groups based on the number of affected vertebrae undergoing surgery: the conventional surgery group ( n=72), with a maximum of three vertebral bodies undergoing PVP during each surgery; the multivertebral surgery group ( n=41), received PVP on more than three vertebral bodies in one surgery. Visual analogue scale(VAS) of pain, Oswestry disability index (ODI), general health status (GH), and mental health status (MH) were assessed before and after PVP to evaluate the efficacy of the procedure. Complications of the patients were systematically assessed to evaluate safety. Measurement data was expressed as mean±standard deviation( ± s), independent sample t-test was used for inter-group comparison, and paired sample t-test was used for intra-group comparison; the comparison of count data was conducted using Chi-square test. Results:After 6 months of surgery, the ODI score, GH score and MH score of the conventional surgery group was (35.28±1.74)%, 57.85±2.11 and 61.20±3.67, all of which improved significantly compared to before surgery, and the difference was statistically significant ( P<0.05). After 6 months of surgery, the ODI score, GH score and MH score of the multivertebral surgery group was (35.67±1.92)%, 64.12±1.35 and 59.80±3.81, all of which improved significantly compared to before surgery, and the difference was statistically significant ( P<0.05). There was no significant difference in ODI score and MH score between the two groups after 6 months of surgery ( P>0.05). At one week after surgery, the pain VAS score in the conventional surgery group (3.51±0.21) was lower than that in the multivertebral surgery group (3.98±0.32), and the difference was statistically significant ( P<0.05). GH score in the conventional surgery group showed significantly greater improvement than that in the multivertebral surgery group after 6 months of surgery, and the difference was statistically significant ( P<0.05). Bone cement leakage occurred in 21 vertebra of the conventional surgery group, and 24 vertebra of the multivertebral surgery group, with leakage rates of 14.8% and 13.0%, respectively, with no statistical significance between the two groups ( P>0.05). Conclusions:Single PVP surgery can safely and effectively alleviate the pain of multi-segment osteolytic spinal metastases and improve spinal mobility. Meanwhile, improving mental health and reducing functional impairments. But the short-term pain relief and long-term general health of the multivertebral surgery group were lower than those of the conventional surgery group.
