SpineSource Launches Expandable Lumbar Interbody Cage in U.S.

April 5, 2016 – LOUIS, MO – SpineSource, Inc. announced today the U.S. launch of the L-Varlock Lumbar Cage. The L-Varlock is the only expandable interbody that can adjust in situ from 0° to 24° of lordotic angle and up to 7 mm of expansion.

The L-Varlock is made of titanium alloy and is currently being launched through SpineSource’s independent group of spinal implant sales professionals throughout the United States.

“Once again, it’s back to the future with spine,” said Tom Mitchell, Founder and CEO of SpineSource. “It is now clear that expandable devices are the future of interbody fusion and titanium has made a comeback. With L-Varlock, surgeons can dial-in any custom lordotic angle necessary to restore and maintain sagittal balance and disc height. He added, “I am pleasantly surprised how quickly U.S. surgeons are gravitating back to titanium because of the bone-friendly properties over PEEK.”

Expandable lumbar interbody devices have rapidly been accepted since SpineSource launched the expandable WAVE® Cage manufactured by Advanced Medical Technologies, AG (Germany) in 2009. Medtronic, Inc. acquired the WAVE® in 2012.

Just to add a little more about SpineSource outside of the attached:

Based in the St. Louis suburb of Chesterfield, MO., SpineSource has a rich history spanning more than a decade of introducing new spinal implant technologies to the United States from Europe.

It started in 2004 with the Ulrich (Germany) Expandable Vertebral Body Replacement (VBR): the first dial-in expandable VBR in the nation.  Many competitors have since introduced this technology.

Then in 2008: the first steerable TLIF from Advanced Medical Technologies, AMT, Germany (LOOP) followed by the first ever expandable lumbar interbody device made of PEEK (WAVE).  Ulrich Medical eventually bought our business after just 18 months on the market, forming their own US subsidiary in Chesterfield, MO.  Then in 2012, Medtronic acquired AMT outright and purchased the US business for WAVE and LOOP devices.  Many competitors have now launched expandable interbody devices.

Today, we start our ‘back to the future’ launch of expandable TITANIUM lumbar interbody fusion devices called L-Varlock (France).  We will see how we do.  What is great about this device is the amount of sagittal balance it can restore and the amount of disc height it can help distract and maintain until a fusion takes place.
