Common questions

What is an interspinous process device?

What is an interspinous process device?

An interspinous process device, the Device for Intervertebral Assisted Motion (DIAM™) designed to treat lumbar neurogenic disease secondary to the lumbar spinal stenosis, it provides dynamic stabilization after minimally invasive (MI) lumbar decompression.

How long does VertiFlex surgery take?

How long does the procedure take? Generally, the procedure takes 15 to 45 minutes to perform depending on whether one or two spacers are implanted.

What is interspinous space?

An interspinous spacer is a device that is inserted into the back of the spine, between the spinous processes. The device is used to treat spinal stenosis.

Is VertiFlex procedure painful?

This simple outpatient procedure was developed with patient safety and comfort in mind, with clinical evidence of long-term relief. This procedure aims to provide stenosis sufferers the freedom to get on with their daily lives without the burden of pain.

What is the success rate of Vertiflex?

84.1% success in function and symptoms at 5 years. > 70% reduction in leg pain at 5 years. 74.7% without reoperation at 5 years.

How successful is Vertiflex?

The effects of Vertiflex are long-term, with 90% of patients reporting satisfaction with the procedure five years later.

What does the interspinous ligament connect to?

The interspinous ligaments (interspinal ligaments) are thin and membranous ligaments, that connect adjoining spinous processes of the vertebra in the spine. They extend from the root to the apex of each spinous process. They meet the ligamenta flava in front and blend with the supraspinous ligament behind.

Is interspinous ligament continuous?

The most superficial fibers of this ligament extend over three or four vertebræ; those more deeply seated pass between two or three vertebræ while the deepest connect the spinous processes of neighboring vertebrae. Between the spinous processes it is continuous with the interspinal ligaments.

Can a Vertiflex dislodge?

Though the Vertiflex procedure is considered to be safe and effective, there are risks. In rare cases, the Superion implant could become dislodged or the spinous processes of your vertebrae could fracture when the implant is placed.

How are Interspinous Process devices used in medicine?

Interspinous process devices (IPD) have been developed to achieve indirect decompression by limiting lumbar extension of the abnormal joint and enlarging the spinal canal and neuroforamen.

What kind of procedure is Interspinous Process Decompression?

Interspinous process decompression (IPD) is a minimally invasive procedure that spine surgeons use today to try to relieve symptoms of lumbar spinal stenosis. IPD reflects the advances made in minimally invasive spine surgery, and is sometimes performed as an alternative to decompression spine surgery, such as a laminectomy.

How does the Interspinous Process spacer surgery work?

The surgery involves placing a metallic/plastic spacer in between the spinous process of the adjacent vertebrae. The surgery benefits the patients via decompressing the spinal nerve roots and the thecal sac. The spinal cord runs in the vertebral canal and gives numerous branches (spinal nerves) as it travels down the canal.

Are there Interspinous Process devices for lumbar spinal stenosis?

Interspinous process devices have been compared to decompressive laminectomies for lumbar spinal stenosis in randomized studies.
