New expandable lumbar interbody spacer launched


Globus Medical has launched the Latis, a minimally invasive expandable lumbar spacer for the management of patients with degenerative disc disease.

A press release reported that the new spacer is inserted through a minimally invasive transforaminal lumbar interbody fusion approach and then is expanded laterally to provide a footprint and graft volume equivalent to an anterior lumbar interbody fusion spacer or lateral lumbar interbody fusion spacer.

The 10mm-wide titanium implant can be inserted posteriorly and can expand in-situ up to 26mm square, offering the largest single bone graft chamber for any posterior implant on the market.  Designed to reduce subsidence and migration, the spacer has a locking set screw that secures deployment at any position within the expansion range.

The Latis system includes customised disc preparation and sizing instruments to simplify the procedure for an efficient minimally invasive transforaminal lumbar interbody fusion approach. The system includes a variety of footprints, heights, and lordotic configurations, for a customised fit for each patient. A single instrument is used for insertion, expansion, locking, and bone graft delivery.

“This new addition to our minimally invasive surgery portfolio is the first expandable implant on the market to offer the benefits of a traditional anterior implant, without the two-part disruptive surgical procedure. Combined with posterior stabilisation using our Revolve minimally invasive pedicle screw system, the entire procedure is designed and intended to maximise preservation of the stabilising muscles of the lower back,” commented Andrew Iott, senior vice president, Global Product Development.
