February 21, 2007 FOR IMMEDIATE RELEASE DEPUY SPINE INTRODUCES NEW AEGIS™ ANTERIOR LUMBAR PLATE SYSTEM Company's First Anterior Plate System Has Lowest Profile on the Market RAYNHAM, MA, February 21, 2007 - DePuy Spine, Inc., a Johnson & Johnson company, today introduced the AEGIS™ Anterior Lumbar Plate System, the company's first anterior plate system designed to treat degenerative conditions of the lumbar spine. With a plate specifically designed to correspond to the lumbar spinal anatomy, AEGIS has the lowest profile of any anterior lumbar plate system and is the only one that can be implanted mid-line or laterally between any two vertebrae in the lumbar region, including the sacrum (L1-S1). Unlike existing plates that attach to the vertebral plane, AEGIS is contoured to recess into the space between two vertebral bodies and features angled tabs (15 degrees) that attach the plate to the cortical rim (anterior edge) of the vertebrae. The plate also uses a patented screw locking mechanism that uses cams instead of screw covers or other means to hold the screws in place. The Tri-lobe CAM-LOC™ apparatus adds no additional profile to the construct, and provides positive feedback that the screws are locked. "This system's unique design minimizes vascular and tissue interference and allows placement along the entire length of the lumbar spine," said Robert D. Fraser, MD, of The University of Adelaide, South Australia. "It is the most versatile anterior lumbar plate system available." AEGIS also has a unique, semi-rigid design that allows for load sharing between the construct and the bone graft, reducing the risk of screw breakage and encouraging fusion. The thin, cam-based construct and corresponding screw preparation instrument set give surgeons optimal visualization at the operative site, and allow implantation in fewer steps using fewer tools than other lumbar plate systems.
