Dr. Chang is the only doctor in the area that performs vertebral augmentation with the Kiva VCF treatment System.  Kiva features a flexible implant made from a playmaker material widely used in spinal implants. The Kiva implant is designed to function as an internal cast providing a mechanical support structure to spinal fractures. Kiva has been shown to reduce pain and restore function for patients with VCFs.


In comparison to a balloon kyphoplasty, Kiva was shown to:

  • Reduce the rate of adjacent level fractures

  • Improve kyphotic angle restoration

  • Reduce rate of cement extravasation

  • Reduce cement volume

1. A coil is advanced to create a path through the vertebral body bone and provide a pathway for the Kiva Implant.


2. As the loops of the Kiva Implant are delivered into the bone, they form a column structure.


3. The coil is removed and the Implant is left in place providing a path for the delivery of bone cement.


4. Once cured, the cement interlocks the Implant to the bone.
