Title : Unilaterally extrapedicular versus transpedicular kyphoplasty in treating osteoporotic lumbar fractures: A randomized controlled study
Abstract:
Objectives: The unilaterally extrapedicular approach is adopted increasingly to perform balloon kyphoplasty in treating osteoporotic lumbar fractures, which is intended to improve radiological and clinical efficacy. We compared the efficacy and safety of this method with a unilaterally transpedicular approach.
Methods: The unilaterally extrapedicular approach is adopted increasingly to perform balloon kyphoplasty in treating osteoporotic lumbar fractures, which is intended to improve radiological and clinical efficacy. We compared the efficacy and safety of this method with a unilaterally transpedicular approach.
Results: A total of 80 participants were assigned to the treatment group (n=40) and control group (n=40), with three and two patients lost to follow-up during 12 months in the two groups respectively. At one month postoperatively, the treatment group showed a greater reduction in VAS score from baseline, compared with the control group (mean difference between groups=0.63, 95%CI 0.19-1.06). There were no significant between-group differences in restoration in anterior, middle, and posterior vertebral body (P > 0.05). No significant differences were found in the rate of cement leakage and perioperative hemoglobin loss (P > 0.05).
Conclusion: Compared with balloon kyphoplasty via the unilaterally transpedicular approach in treating lumbar OVCFs, the unilaterally extrapedicular approach appears to be promising in achieving effective pain relief, adequate cement infusion, short operation time, less fluoroscopy exposure, and comparable risk of cement leakage and vessel injury. It is an alternative approach for lumbar OVCFs treated by kyphoplasty.
