Compare Vertebroplasty, Kyphoplasty and Crosstrees System for PVA

What is Vertebroplasty?
Vertebroplasty is a percutaneous (through the skin) treatment for vertebral compression fractures. A special needle is inserted into the spine and liquid bone cement is injected into the vertebral cavity to strengthen the bone and relieve pain. Vertebroplasty is a minimally invasive procedure that is often performed under general anesthesia.

What is Kyphoplasty?
Kyphoplasty is a similar type of percutaneous (through the skin) treatment for vertebral compression fractures. A small balloon is inserted into the vertebra using a hollow instrument. The balloon is inflated to raise the collapsed vertebra and once positioned correctly, is deflated and removed. The cavity is then filled with bone cement to support the bone. Kyphoplasty is performed using local or general anesthesia.

Benefits of the Procedures:
Nearly 90% of patients experience an immediate and significant reduction in pain.1 Other benefits include improvements in mobility and quality of life from resuming normal daily activity.

What is the Crosstrees System for PVA?

The Crosstrees System for percutaneous vertebral augmentation (PVA) is an FDA approved procedure similar to vertebroplasty and kyphoplasty, the standard surgical treatments for vertebral compression fractures. However, the Crosstrees PVA system is designed to control bone cement delivery and has been shown to decrease the risk of cement leakage associated with vertebroplasty and kyphoplasty. In a small percentage of patients, those cement leaks can result in significant health issues.

As in vertebroplasty and kyphoplasty procedures, the physician will insert the Crosstreess Pod into the fractured vertebral body through a very small incision in the spine. The Pod will be filled with liquid bone cement and then opened and removed so that only the bone cement remains. The Crosstrees procedure is be comparable in time to other PVA treatments and can be performed under local or general anesthesia. Recovery time is expected to be brief and most patients are expected to be up and walking within hours.

Types of Fractures

In the United States alone, more than 700,000 vertebral compression fractures occur every year. Some fractures are caused by trauma, but the vast majority—85 percent—of vertebral compression fractures are caused by osteoporosis. In this case, even a sneeze or reaching overhead can cause a fracture. The bone inside the vertebral body causes it to weaken and collapse, resulting in severe pain. Vertebral compression fractures usually occur in the middle and lower sections of the spine. If not treated properly, they can lead to the loss of height, posture deformity and pulmonary complications.2

Pathologic Fractures
The Crosstrees System is indicated for treatment of pathologic fractures caused by osteoporosis. Examples of these types of fractures appear below

Osteoporosis Information and Resources

Osteoporosis is a disease of bone that leads to a decrease in bone density and an increased risk of fracture. Osteoporosis may result in bones that have become weak and brittle. If undetected, osteoporosis can lead to a fracture, or compression in the spine, even from normal daily activities. This is often referred to as a spinal fracture or vertebral compression fracture (VCF).

Vertebral compression fractures usually occur in the middle and lower sections of the spine. If not treated properly, they can lead to the loss of height, posture deformity and pulmonary complications.3


Risk Factors

• Females over the age of 50
• Women are four times more likely than men to develop osteoporosis.
• Family history
• Inactive lifestyle
• Long term use of steroid medication
• Low lifetime intake of calcium
• Smoking
• Excessive use of alcohol
• Women who are thin and have a small bone structure
• Caucasian and Asian women are more likely to develop osteoporosis
• Prior bone fracture

Symptoms
If you have any of the following symptoms, you should be evaluated by a medical professional to determine whether or not you have a spinal fracture:

• Sudden onset of back pain
• Unable to perform normal activities and exercise due to back pain
• Ongoing chronic back pain
• Loss in height with associated back pain


Prevention

• Take calcium supplements
• Take vitamin D or eat food rich in vitamin D and calcium
• Get regular exercise, especially strength-building exercise
• If you are at high risk, consult with your doctor about bones strengthening medications
