LATIS® is an innovative expandable lumbar interbody fusion spacer providing an ALIF footprint through a TLIF approach. MIS Approach, Maximized Footprint: LATIS® expands laterally in situ, optimizing apophyseal ring engagement to potentially reduce subsidence. Maximized Fusion Bed: Once expanded, LATIS® creates a substantial single graft chamber allowing for a distinctively large fusion mass. Migration Resistance: The expanded implant geometry and slotted tooth pattern are designed to help resist implant migration.
