Effectiveness and safety of percutaneous vertebroplasty in the treatment of spinal metastatic tumor

Objective: to evaluate the effectiveness,safety and feasibility of percutaneous vertebroplasty in the treatment of spinal metastatic tumor. methods: thirty-four patients with spinal metastatic tumor who received treatment in the first affiliated hospital of zhengzhou university from may 2014 to june 2015 were selected. totally fifty diseased vertebrae were treated by percutaneous vertebroplasty. the curative effects were evaluated according to visual analogue scale (vas) score,oswestry dability index (odi) and dose of pain reliever. the leakage conditions of bone cement and clinical complications were observed. the patients were followed up for 3 to 12 months. results: the average vas score and odi 24 h after treatment were much lower than those before treatment,and the difference had statistical significance (p<0.05). the average vas score and odi at different followup periods after treatment were not significantly different (p>0.05). during follow up,nine patients stopped taking pain reliever,the dose of 18 patients had obvious reduction,and 7 patients kept previous dose; the incidence of bone cement leakage was 38.25%. six patients had fever after surgery,but recovered after expectant treatment; 2 patients felt uncomfortable in the right lower limbs,but relieved after expectant treatment. conclusion: percutaneous vertebroplasty can relieve pain efficiently,improve the daily living ability,and significantly enhance the living quality of patients with spinal metastatic tumors,with small trauma and high safety. © 2017,professional medical publications. all rights reserved.
