Eccentric Humeral Head
Anatomical Glenoid

Modular Body After implanting the stem, the height of the implant can be adjusted in 5mm increments by selecting the appropriate body. The body is attached in-situ to the stem and then freely rotated about the stem to fine tune version during assembly. Lateral and medial suture holes allow for fracture attachment.

Dual-Tapered Stem A unique feature of the cementless, modular stem is the dual tapered, rectangular cross-section design that promotes primary stability.

The grit blasted surface creates a micro-structure that promotes secondary stability and stimulates osseointegration (2).

Innovative Inclination Set The patented inclination set is truly innovative. A stepless inclination of ±12° in any direction is possible allowing optimal positioning of the head to match the patient's anatomy.

Eccentric Humeral Head Eccentric heads replicate the natural humeral head anatomy and provide exact adaptation of the distance of the head center to the stem axis. Heads are available in 8 sizes for optimal coverage of the osteotomy site.

Anatomical Glenoid There are 12 cemented glenoid components available (4 sizes and 3 radii within each size). Each glenoid size is designed to match the glenoid fossa. The glenoid radius has a 3 to 5 mm mismatch from the radius of the corresponding humeral head thereby recreating normal kinematics by permitting rotational and translational movement of the humeral head (1).

Four pegs in combination with cement pockets promote optimal fixation of the pear-shaped glenoid component.
