CALIBER™ Spacer

CALIBER™ is an innovative expandable lumbar fusion device that represents the future of MIS by optimizing endplate-to-endplate fit and minimizing insertion force. Insertion of CALIBER™ is performed at a contracted height to help reduce the amount of nerve root retraction required and to preserve musculoskeletal composition. Continuous expansion of CALIBER™ is designed to restore disc height, while controlled distraction helps to properly tension the annulus and surrounding ligaments.
