No significant difference in cement leakage between radiofrequency & balloon kyphoplasty

Study Type: Therapy
OE Level of Evidence: 2
Journal Level of Evidence: N/A
100 patients with thoracolumbar vertebral fracture were randomized to either radiofrequency kyphoplasty or balloon kyphoplasty. The purpose of this study was to compare the rate of cement leakage between the two groups. Postoperative leakage observed Please login to view the rest of this report.

Why was this study needed now?
Balloon kyphoplasty, a cement augmentation technique for unstable vertebral bodies, has been a standard surgical option to address vertebral fractures in patients with osteoporosis. One of the more important complications to monitor associated with kyphoplasty is cement leakage into surrounding areas, which can result in clinically relevant sequelae. A newer technique of kyphoplasty - radiofrequency kyphoplasty - has been more recently introduced. There is a lack of comparative literature between these two options, particularly concerning complications related to cement leakage.
What was the principal research question?
Is there any significant difference in the rate of cement leakage after radiofrequency kyphoplasty versus balloon kyphoplasty for vertebral fracture?
Population: 100 patients with symptomatic vertebral fracture(s) of the thoracic and/or lumbar spine occurring within the previous 12 weeks.
Intervention: Radiofrequency kyphoplasty: Patients were treated with radiofrequency kyphoplasty at all affected levels (n=83 kyphoplasties performed)
Comparison: Balloon kyphoplasty: Patients were treated with balloon kyphoplasty at all affected levels (n=79 kyphoplasties performed)
Outcomes: The primary outcome was the incidence of cement leakage (defined as appearing >1mm outside of corticals on X-ray and/or CT. The localization of the leakage was also categorized as either epidural, intradiscal, extracorporal, or intravasal. The amount of cement used in each case was also recorded. Intraoperative pulmonary, vascular, and neurological complications were documented.
Methods: RCT
Time: Images were obtained postoperatively.
