Humeris ® Reversible
Convertible Shoulder Prosthesis
The Humeris ® Reversible is a 135° neck shaft angle platform-style convertible stem. The short 100mm humeral stem has a dual geometry proximally designed to ensure better cement less fixation. The distal end has a smooth polished surface if cementing is required and a flat area for better diaphyseal stability. The plasma sprayed CP Ti (titanium) and HA (hydroxyapatite) coating proximally is designed to promote long term fixation.
Features include 11 cementless stem size options (8mm to 20mm), 3 glenosphere sizes (32, 36 & 40mm), all with a 3.5mm lateralization, 6 heights of UHMWPE polyethylene humeral cups with face changing from 135° to 145° including stability and standard depth (54 combination possible) and our First-and-Only-to-Market Titanium Nitride (TiN) coated alternate bearing surface option glenosphere.
The humeral cups are thermocompressed polyethylene onto a titanium alloy shell to attach the humeral cup to the stem with a double morse taper that eliminates the need for back table assembly and possible backside wear.
The glenoid baseplate is the smallest on the market with a 24mm diameter and 2 options: a central peg with post lengths available in +6mm or +10mm (see picture); or, a central screw (8mm to 20mm) option that allows for further compression.
There are lateralized glenoid baseplates in both central peg or central screw styles with lateralization of +3mm or +6mm. There are, additionally, 7.5° or 15° half-wedge augments with the possibility of +3mm or +6mm of lateralization. The half-wedge augments are only available in the central screw option. There are 12 total options of glenoid baseplates offered in the FX portfolio.
