Insignia leverages more than 1,300 CT scans utilizing a 3D modeling and analytics system, the Stryker Orthopaedic Modeling and Analytics (SOMA) bone database. The stem is engineered to optimize fit and function.1
Key features include:
A size-specific medial curvature to support cortical engagement.2,3,4
An optimized A/P fill* which is designed to preserve bone and prioritizes M/L fit prior to A/P filling of the femur.
A size specific collar engineered to maximize calcar coverage1
A direct lateral offset of +5mm across the size range to enable independent adjustment of offset while maintaining leg length.
A slim distal profile designed to accommodate varying size femoral canals
Insignia also utilizes a patent-pending Tri-Stage™ Broach that features:
• Extraction teeth facilitate cancellous bone removal for enhanced cortical fit1
• Compaction teeth enable bone preservation and initial stability
• Distal diamond cutting teeth help remove diaphyseal bone and are oversized by 0.5mm to promote proximal fit
*Optimization subject to particular design constraints.
