Zavation Medical Products introduced its Titanium/PEEK Posterior (Lateral Expandable Interbody Fusion) LEIF cage for lumbar spinal fusion.
The device is designed to provide structural stability with a shape that accommodates a posterior or transforaminal approach to the lumbar spine. Various heights and geometric options suit anatomical needs of a variety of patients. Expansion to a larger footprint doubles the volume of autogenous bone graft material.
Once expanded, the hybrid LEIF cage is wider than the incision through which it was inserted, lessening the possibility of posterior migration.
Zavation Posterior LEIF implants are intended for use with supplemental internal fixation, such as the Zavation Spinal System.
