Humelock II ® Reversible

Trauma Convertible Prosthesis

The Humelock II ® Reversible is a convertible stem with a 135° neck shaft angle platform-style convertible stem for trauma cases only. The stem (120mm) has a Unique-To-Market fixation with distal interlocking screws (18mm to 36mm) that allow the surgeon to set the Height & Version intraoperatively with an aiming guide. The plasma sprayed CP Ti (titanium) and HA (hydroxyapatite) coating proximally is designed to enable healing of the tuberosities and to promote long term fixation.
The reattachment of the tuberosities is made easier by having a non-filling proximal stem (Orthopaedics & Traumatology: Surgery & Research 105 (2019) 805–811) that uses the hole medially to ensure the sutures are well attached and the tuberosities well fixed.
Features include 4 cementless stem size options (8mm to 14mm), 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.
Cemented options are also available (6mm to 12mm).
