Percutaneous kyphoplasty for treatment of osteoporotic vertebral body compression fractures in the elderly

Abstract

Objectives To study the clinical effects of percutaneous kyphoplasty on senile osteoporotic vertebral body compression fractures. Methods The 87 elderly patients with osteoporotic vertebral body compression fractures were randomly grouped into control group (n=42) treated with percutaneous vertebroplasty and observation group (n=45) treated with percutaneous kyphoplasty in our hospital from June 2013-March 2016.And the clinical curative effect before and after treatment was compared and analyzed. Results The visual analog scale (VAS) pain score in observation group versus control group was (8.49±2.86) vs.(8.56±2.98), (t=0.11, P>0.05) before treatment, and[(2.58±1.34) vs.(3.34±2.01), t=2.09, P< 0.05], [(2.06±0.97) vs (3.87±1.96), t=5.51, P<0.05]and[(1.09±0.89) vs (2.37±1.29)], t=5.42, P<0.05]at 1 week, 4 weeks, and 12 weeks after treatment respectively, showing statistically significant improvement after treatment.The data of kyphosis angle by using Cobb angle, Oswestry lumbar dysfunction index (ODI), mean time of postoperative ambulation, and mean postoperative hospital stay were similar to that of the visual analog scale (VAS) pain score, showing statistically significant improvement after treatment (all P<0.05). The incidence[cases (%)]of bone cement leakage was lower in observation group[3(6.7)]than in control[9(21.4)](χ2=3.98, P<0.05). Conclusions Clinical treatment effects of percutaneous kyphoplasty on the elderly patients with osteoporotic vertebral body compression fractures are superior to that of percutaneous vertebroplasty.Percutaneous kyphoplasty can effectively relieve pain, and improve body function disorders and the quality of life.
