Abstract:
Objective To compare the clinical efficacy of percutaneous kyphoplasty (PKP) by balloon dilatation between unipedicular and bilateral pedicle approach for the treatment of osteoporotic vertebral compression fractures (OVCF). Methods From January 2012 to March 2014, 56 patients with single-level or double- level OVCF were randomly divided into two groups. 29 patients with 33 vertebral bodies were performed by PKP through unipedicular approach and 27 patients with 31 vertebral bodies through bipedicular approach , used PMMA bone cement filling vertebral. The clinical data of patients were prospectively analyzed and the clinical efficacy was compared between two groups. Results The VAS scores, Beck value, Cobb angle and ODI scores after operation improved in both groups (P < 0.01),but there were no significant difference between two groups(P > 0.05). The operative time, X-ray exposure time and volume of bone cement in unilateral group were less than that of bilateral group(P < 0.01). There were no significant difference in the incidence of bone cement leakage ,the pain relief and the incidence of complications between two groups (P > 0.05). Conclusion Both unipedicular and biopedicular PKP are significant improvement for the OVCF, vertebral strengthen showed similar efficacy, but the former has easy operation procedure, can shorten operative time and reduce X-ray exposure time and less volume of bone cement.
