Lumbar Stabilization

Sturdy, Flexible, Nonrigid Fixation

Lumbar Stabilization

Lumbar Stabilization is a surgical technique in which a flexible and sturdy titanium device (Coflex) is inserted between the lamina to provide support, relieve pressure, and preserve motion. Specifically, it is inserted in between and attaches to the above and below spinous processes, which look like spikes or ridges on the posterior of the spine.

coflex® Interlaminar Technology

The Coflex Interlaminar Stabilization Device is a Class III FDA approved device with Level I evidence that supports its clinical and financial benefits when compared to other surgical options such as fusion. This surgical technique is used to treat conditions such degenerative lumbar spinal stenosis and lumbar spondylolisthesis which are described below.

Spinal Stenosis (Spinal Compression)

Impaired lumbar discs apply pressure on the spinal cord and nerve roots, located in a tubular channel (Spinal Canal) that runs up the spine, causing numbness, weakness, or pain in the lower back, buttocks, and/or legs.

Lumbar Spondylolisthesis

One lumbar vertebrae shifts over the one below it due to weakness or impairment in the facet joints. This causes spinal instability and can also apply pressure on the spinal nerves and canal leading to numbness, weakness, or pain in the lower back, buttocks, and/or legs. Spinal issues are more common in the lumbar spine because it holds up the weight of the entire head and torso. Overtime, this pressure accompanied with the natural wear and tear of age can weaken the joints. Lumbar Spondylolisthesis is common in both men and women over the age of 50 but there is a higher prevalence in women.5

Lumbar Stabilization vs. Lumbar Fusion

The Coflex device is a nonrigid fixation, therefore it provides better and more natural lumbar function when compared to fusion, which completely restricts the natural movement of the spine. Other benefits of Lumbar Stabilization compared fusion include:

LS vs. LFLumbar StabliizationFusion
Quality Adjusted Life Years Higher1Lower1
Overall Composite Clinical Success (CCS) Scores at 60 months Higher (55.1%)2Lower (36.4%)2
Range of Motion Does not completely eliminate motionComplete loss of motion
Adjacent Segment Degeneration (ASD) using Pfirrmann’s Disc Degeneration Grading System Less common and less severe4More common and more severe4

Blood Loss Less3,4More3,4
Inpatient Length of Stay (LOS) and Ambulation Time (how long until the patient returns to light activity) Shorter3,4Longer3,4
Non-union spinal fusion (pseudarthrosis) Eliminated because the disc is replacedPossible because the discs are grafted together
Secondary Surgery Lower (13% of patients)2Higher (25.7% of patients)2
