Companion Spine is a medical device company building a full continuum of interventional and surgical therapies for back pain caused by degenerative disc disease and lumbar spinal stenosis. Founded in 2020 by the Viscogliosi Brothers, it focuses on posterior dynamic stabilization and motion-preserving implants - such as DIAM, coflex, CoFix, LISA and APERIUS - that treat spine conditions without spinal fusion. With headquarters in New York and Mérignac (Bordeaux), France, the company aims to offer surgeons a single, indication-specific portfolio spanning diagnosis, pain management and outpatient surgery.
