Abstract
Objective To compare the therapeutic effect of percutaneous vertebroplasty ( PVP) alone and percutane-ous pedicle instrumentation combined with PVP for metastatic spine tumors. Methods Forty-three patients with me-tastatic spine tumors were divided into two groups:PVP alone as group 1 and percutaneous pedicle instrumentation combined with PVP as group 2. Postoperation 7 d, 12 months, visual analogue scales(VAS),Oswestry disability in-dex( ODI) of two methods were compared respectively. Results All patients were followed up for 24~59 months. Preoperation and postoperation 7 d, 12 months,VAS were 2. 70 ~3. 90 ( 3. 39 ± 0. 44 ) ,2. 00 ~3. 40 ( 2. 73 ± 0. 57 ) pointsingroup1,and2.60 ~4.00(3.39±0.54),2.10 ~3.50(2.83±0.56)pointsingroup2.ODI: 19.00 ~25. 50(22. 54 ± 2. 17),24. 10 ~25. 67(25. 37 ± 0. 15) points in group 1,and 19. 11 ~25. 52(25. 54 ± 2. 17), 22. 12~24. 42(23. 37 ± 0. 13) points in group 2. There were significant differences between two groups(P<0. 05), and group 2 was better than group 1. Vertebral tumor recurrence occurred in 1 patient, and 2 patients in group 2. There were no significant differences between two groups(P>0. 05). Conclusions For multiple segmental metastat-ic spine tumors,compared with PVP alone,percutaneous pedicle instrumentation combined with PVP is more effective in correcting deformity,relieving pain,maintaining vertebral height and restoring spinal stability.关键词
