Percutaneous vertebroplasty in treating osteoporotic vertebral fracture pseudarthrosis

Abstract:

Objective：To evaluate the clinical outcome of percutaneous vertebroplasty（PVP） in treating osteoporotic vertebral fracture pseudarthrosis. Methods：Fifty-four patients underwent PVP were involved. Visual analogue scale（VAS） and MacNab scale were recorded before the operation and on 1 d and at 1 month，3 months，12 months after the operation. In addition，X ray and CT exami－nation were conducted on 1 d postoperatively. After data collection，SAS software was used to do ANOVA for repeated measurement. Results：Follow-up（12 months） was achieved in 48 patients out of 54 patients. VAS（F=142.481，P=0.000） and MacNab（F=144.207，P=0.000） scores significantly improved on 1 d（VAS=3.120±1.076；MacNab=2.940±0.598） and at 1 month（VAS=2.620±0.874；MacNab=3.060±0.697），3 months（VAS=2.320±0.726；MacNab=3.210±0.683），12 months（VAS=1.920±0.686；MacNab=3.440±0.501） after the operation compared with those before the operation（VAS=8.490±0.689，MacNab=1.270±0.449）. Conclusion：Per－cutaneous vertebroplasty is effective in the treatment of osteoporotic vertebral fracture pseudarthrosis.
