Kyphoplasty balloon catheters represent a significant advancement in the field of minimally invasive spine surgery, specifically in the treatment of vertebral compression fractures (VCFs). This medical device plays a central role in balloon kyphoplasty procedures, which aim to restore vertebral height and relieve pain in patients suffering from spinal fractures, most commonly due to osteoporosis or traumatic injury.
What Is a Kyphoplasty Balloon Catheter?
A kyphoplasty balloon catheter is a specialized medical device used in percutaneous balloon kyphoplasty, a procedure designed to treat collapsed or fractured vertebrae. The catheter comprises a flexible shaft attached to a high-pressure inflatable balloon. During surgery, the balloon is inserted into the fractured vertebral body through a small incision and then gradually inflated. This process creates a cavity within the vertebra and helps restore its height before bone cement is injected to stabilize the structure.
These catheters are typically made of biocompatible materials that can withstand high pressures, such as thermoplastic polyurethane (TPU) or nylon. They must be flexible enough to navigate spinal anatomy, yet strong enough to elevate collapsed vertebral segments safely and effectively.
Principles and Mechanism of Kyphoplasty
Balloon kyphoplasty works on the principle of mechanical height restoration and internal stabilization. The procedure begins with fluoroscopic guidance to insert a trocar or cannula into the affected vertebral body. The kyphoplasty balloon catheter is then advanced into the vertebral body through this access channel.
Once in place, the balloon is inflated using a contrast medium to visualize its expansion under X-ray imaging. As the balloon inflates, it gently compacts the cancellous bone and lifts the endplates of the vertebra, aiming to restore lost height. After achieving the desired expansion, the balloon is deflated and removed, leaving behind a cavity that is then filled with polymethylmethacrylate (PMMA) bone cement. This cement quickly hardens, stabilizing the vertebra and reducing the patient’s pain significantly.
Role of the Balloon Catheter in Kyphoplasty
The balloon catheter is the cornerstone of this minimally invasive technique. It serves several key purposes:
-
Vertebral Height Restoration: The balloon exerts controlled pressure to lift the collapsed vertebral body.
-
Cavity Creation: It forms a uniform space within the vertebral body, which allows for targeted cement deposition.
-
Minimized Cement Leakage: By pre-forming the cavity, the balloon reduces the risk of bone cement leaking into surrounding tissues or spinal canal.
-
Anatomical Realignment: It helps correct spinal deformities such as kyphosis caused by vertebral compression.
Without the balloon catheter, these critical benefits would not be possible, and the procedure would revert to simpler forms of vertebroplasty with higher complication rates.
