How Balloon Kyphoplasty Works
Step by Step
Balloon kyphoplasty is a minimally invasive treatment for spinal compression fractures (also called vertebral compression fractures of VCFs). Kyphoplasty is similar to vertebroplasty; the main difference is that kyphoplasty uses a small balloon that gently lifts bone fragments into their correct position.
- Creating a space for the balloon
The surgeon will make a pathway into the fractured vertebra using a hollow instrument. A small balloon is then guided through the instrument into the bone.
- Inflating the balloon
Once in position, the balloon is slowly inflated to gently raise the collapsed bone into its normal position.
- Removing the balloon
When the bone is in the correct position, the surgeon deflates and removes the balloon. This leaves behind a void—or cavity—within the vertebral body.
- Filling the vertebral void
To prevent the bone from collapsing again, the void is filled with orthopaedic cement.
- Forming the internal cast
Once set, the cement forms a cast inside the vertebral body that stabilizes the bone. To fully secure the bone, the procedure is sometimes performed on both sides of the vertebral body.
Balloon kyphoplasty usually takes about a half hour per level, and most patients are discharged from the hospital within a day of their surgery. If you think kyphoplasty may be a treatment option for your spinal compression fractures—or if you’re interested in learning more about this surgery—talk to your doctor.
