Abstract

Background: Studies have found that unilateral and bilateral kyphoplasty have comparable clinical outcomes. Only a few studies have compared the radiographic results of using unilateral vs. simultaneous bilateral approaches. We aimed to examine and compare the radiographic results of unilateral (UKP) vs. bilateral simultaneous double-balloon kyphoplasty (DKP) for treating symptomatic vertebral compression fractures (VCF).

Methods: A retrospective cohort of all patients treated for VCF by DKP and UKP over five years in a single medical center. From 2009 to 2012, we routinely performed UKP; from 2012, DKP was the routine due to potential benefits in vertebral realignment. We evaluated pre- and post-surgical fracture characteristics including vertebral height, sagittal and coronal Cobb angle, and fracture reduction. Statistical analysis included a -test for independent variables and Pearson's correlation.

Results: The study cohort consisted of 81 patients (75.8 years ± 10.86) who underwent surgery, with a total of 119 vertebras. We performed 89 UKP on fractured vertebras and 30 DKP on 30 vertebrae. The UKP average fluoroscopy radiation exposure was 15.8 mGy (±11.5) per level compared to 11.2 mGy (±8.7) for DKP, = 0.03. DKP showed significant fracture reduction, 2.8 degrees of Cobb angle, equaling the patient positioning effect on fracture reduction.

Conclusion: DKP results in better fracture reduction than UKP, and equals the effect of patient positioning without increased radiation exposure or adverse events.
