Stabilimax NZ Dynamic Spine Stabilization System

The Stabilimax NZ Dynamic Spine Stabilization System, a device designed to provide stabilization while allowing for motion, is now being clinically evaluated.

With aging (or as a result of injury or damage to the lower back), some degeneration of the skeletal and muscular structures of the lumbar area of the spine occurs. This degenerative process creates instability in the spine and a narrowing of the spinal canal, or spinal stenosis. As the narrowing occurs, and as the body tries to compensate, there is compression of the nerve roots, which causes the pain associated with spinal stenosis.

Stabilimax NZ is designed to offer a unique treatment for spinal stenosis call "dynamic stabilization." This means that while Stabilimax NZ works to stabilize the affected area of the spine, it does so in a manner which preserves both bending and twisting motions.

How Does It Work?

The Stabilimax NZ is inserted through pedicle screws similar to those used for posterior lumbar fusion. The device is then attached to the screws. The Stabilimax NZ is comprised of a dual spring mechanism. The inner spring works in spinal extension and the outer spring works in spinal flexion. The springs counter-oppose one another in lateral bending.

The spring mechanism is paired with a ball-and-socket which works in axial rotation (twisting) of the spine. All in all lending to maintained motion similar to that of a healthy spine.

 

Am I a candidate?

In general, patients who have experienced specific symptoms may be eligible when other methods, such as medications and non-surgical treatments, have failed to alleviate their pain.

Inclusion Criteria:

Participants in the clinical research study must meet the following criteria:

• Experience moderate to unbearable pain in the legs and back
  
• Have pain that causes moderate to severe walking impairment
  
• Experience symptoms when walking, standing, or exercising in an upright position
  
• Be unable to get adequate pain relief after six months of non-surgical management
  
• Men and women over 21

Exclusion Criteria:

Some people who meet the inclusion criteria may still be ineligible to participate in the clinical study. This includes the following:

• Prior lower back surgery with the exception of lamino-foraminotomy, microdiscectomy, IDET or percutaneous discectomy
  
• Primary diagnosis of back pain caused by other conditions than spinal stenosis
  
• Patients with peripheral vascular disease requiring intervention
  
• Patients who are receiving immunosuppressive or long-term steroid therapy
  
• Those receiving Worker's Compensation or who are involved in active litigation relating to his/her spinal condition

Other Criteria:

The criteria listed above are not the only eligibility criteria. Only a clinical research study staff member can determine if you are eligible for this clinical research study.
