Overview

A vertebral compression fracture occurs when one of the bones of the spine collapses under load. In people with osteoporosis, this can happen during something as ordinary as bending, lifting a bag of groceries, or a minor stumble. The pain is often sudden, sharp, and worse with standing or walking.

These fractures are frequently attributed to general back pain and left untreated. Untreated, a collapsed vertebra heals in its compressed shape, which shortens the spine and shifts posture forward. Each additional fracture increases the load on the vertebrae above and below it, which is why one compression fracture makes the next one more likely.

Kyphoplasty is a minimally invasive procedure that stabilizes the fractured vertebra from the inside. It is performed under image guidance, takes well under an hour, and is typically completed on a same-day outpatient basis at Padda Institute in St. Louis.

What Is A Vertebral Compression Fracture?

The vertebrae are the stacked bones that form the spinal column. Each one bears the weight of everything above it. When bone density drops — through osteoporosis, long-term steroid use, or certain cancers — a vertebra can lose enough structural strength that it fractures and collapses, most often in a wedge shape at the front.

Common signs include:

  • Sudden back pain that worsens with standing or walking
  • Pain that eases when lying down
  • Limited spinal motion, particularly bending or twisting
  • Loss of height over time
  • A gradual forward curve of the upper back

Diagnosis begins with imaging. An X-ray will often show the collapse, but MRI is frequently needed to determine whether a fracture is recent and still generating pain, or old and already healed. That distinction matters — kyphoplasty is intended for fractures that are still active pain generators.

How The Kyphoplasty Procedure Works

Kyphoplasty is performed with the patient positioned face down, under local anesthetic with sedation. The steps are:

  1. Access. Using continuous fluoroscopic guidance, a narrow pathway is created through the pedicle into the fractured vertebral body. No open incision is required.
  2. Balloon inflation. A small balloon is passed through the pathway and carefully inflated inside the collapsed vertebra. This creates a cavity and, where the fracture allows, restores some of the lost vertebral height.
  3. Cement placement. The balloon is removed and the cavity is filled with bone cement, which hardens within minutes to stabilize the vertebra internally.
  4. Recovery. The pathway is closed with a small dressing. Most patients are monitored briefly and go home the same day.

The entire procedure typically takes 30 to 45 minutes per level treated.

Kyphoplasty Compared With Vertebroplasty

Both procedures stabilize a fractured vertebra with bone cement, and Padda Institute performs both — see our vertebroplasty page for that approach. The difference is the balloon step.

Vertebroplasty injects cement directly into the fractured vertebra without first creating a cavity. It stabilizes the bone but does not attempt to restore height.

Kyphoplasty inflates a balloon first. This creates a defined space for the cement and, in fractures treated before the bone has consolidated, can recover some of the lost vertebral height and reduce the forward angle of the spine.

Which procedure is appropriate depends on the age of the fracture, the degree of collapse, and the surrounding bone quality. That determination is made after reviewing your imaging, not in advance.

Relief From Compression Fracture Pain

Don't let a compression fracture limit what you can do. Connect with us to schedule your consultation and take the first step toward relief.

Who Is A Candidate For Kyphoplasty?

Kyphoplasty is generally considered when:

  • Imaging confirms a vertebral compression fracture that is still an active source of pain
  • Pain has not responded adequately to rest, bracing, and medication
  • The fracture is recent enough that the bone has not fully consolidated
  • Pain is limiting mobility, sleep, or independence

Timing matters. Kyphoplasty is most effective when performed while the fracture is still fresh — generally within weeks to a few months of onset. Fractures that have fully healed in a collapsed position are usually managed differently.

Not every compression fracture requires intervention. Some heal well with conservative care. The purpose of the consultation is to determine which category yours falls into.

General Pre And Post Procedure Instructions

You should eat a light meal within a few hours before your procedure. If you are an insulin-dependent diabetic, do not change your normal eating pattern before checking with our office. Take your routine medications with a small amount of water unless you have been told otherwise.

Tell us in advance if you are taking a blood thinner such as warfarin, clopidogrel, apixaban, or rivaroxaban. These often need to be paused before the procedure, and the timing must be coordinated with the physician who prescribed them.

Because sedation is used, you will need someone to drive you home. Most patients are up and walking within an hour of the procedure. Avoid heavy lifting and strenuous activity for the first several days, and follow the specific activity guidance you are given at discharge.

A compression fracture is often the first clear sign of underlying osteoporosis. Stabilizing the fracture treats the pain, but it does not treat the bone disease that caused it. Bone density evaluation and management should follow.

Kyphoplasty FAQs

The procedure itself typically takes 30 to 45 minutes for a single level. With preparation and recovery monitoring, plan on being at the facility for roughly half a day.

Usually not. Most kyphoplasty procedures are performed under local anesthetic with intravenous sedation, which means you are comfortable and drowsy but not fully unconscious. The approach is decided case by case.

Many patients report meaningful improvement within 24 to 48 hours as the cement sets and the vertebra stabilizes. Individual response varies with the age of the fracture, the number of levels treated, and overall bone health.

If several vertebrae are fractured, more than one level may need treatment. Whether these are addressed in one session or staged depends on your imaging and overall medical condition.

No. Kyphoplasty stabilizes the vertebra that is already fractured. It does not strengthen the surrounding bone. Because a first compression fracture significantly raises the risk of another, evaluation and treatment of underlying osteoporosis is an essential part of care.

Kyphoplasty is generally covered by Medicare and most commercial insurers when imaging confirms the fracture and documentation supports medical necessity. Our office will verify your specific benefits before scheduling.
