Functional description

Poly Liner component of the TM Reverse Shoulder System. Designed to be anti-rotational with a groove on the lateral side of the liner to fit around a boss machined on the lateral side of the proximal rim of the humeral implant to prevent rotation. Offered as a standard or retentive liner. The retentive liner covers a larger surface area of the glenosphere component, achieved by increasing the included angle of the liner. Manufactured from UHMWPE.
