Backed by the clinical and development expertise of shoulder surgeons, this shoulder system replicates as nearly as possible the natural mobility, balance, and stability of the joint. A range of implant sizes matches patient anatomy, thus preserving bone stock. The proportionally sized pegs/keel of the Bigliani/Flatow Shoulder glenoid help to enhance initial fixation. The glenoid articular surface provides a central conforming zone surrounded by a non-conforming zone. This patented variable conformity helps ensure stability throughout the range of motion.
