Reporting Groups
Kiva VCF Treatment System The Kiva® VCF Treatment System is a multi-component, single-use device designed for obtaining unilateral access to the vertebral body in order to deliver the Kiva Implant and bone cement to stabilize osteoporotic vertebral fractures. The Kiva procedure involved placement of the Kiva Implant into the vertebral body followed by injection of PMMA into the Kiva Implant.
Balloon Kyphoplasty The balloon kyphoplasty procedure involved placing an inflatable bone tamp into the vertebral body that was then inflated under fluoroscopic guidance to create a void. This void was then filled with PMMA.
