Fit
Insignia leverages Stryker’s SOMA database to help optimize cortical engagement and proximal fill, even in Dorr Type A femurs.1
Function
Insignia is differentiated by data. The stem features a SOMA designed size-specific collar and SOMA-verified femoral offset.
Flexibility
Insignia was designed for ease of insertion, especially in muscle-sparing approaches.
Fit
SOMA designed geometries
Insignia continues Stryker’s heritage of 3D CT-based implant design through SOMA (Stryker Orthopedics Modeling and Analytics) technology. First used in Accolade II with its size-specific medial curvature, SOMA allows Stryker to dynamically test implant designs to allow for an enhanced implant fit across various femoral morphologies.
Insignia incorporates geometries of two clinically successful stems – the SOMA design of Accolade II and the trapezoidal design of Secur-Fit – to optimize cortical engagement and proximal fill.1,2,14
Tri-Stage™ Broach
Insignia’s Tri-Stage™ Broach is Stryker’s first instrument designed with SOMA technology. The Tri-Stage Broach features three tooth geometries to prepare a tapered press fit region to allow for an reliable and reproducible stem seating height relative to the final broach.1,15
Function
Size-specific collar
The SOMA-designed size specific collars (5-7mm) help maximize calcar coverage, while minimizing overhang across various femoral morphologies.1 Insignia’s collar sizes increase proportionally to the implant body to help minimize the likelihood of psoas impingement from implant overhang.3
SOMA-verified femoral offset
Insignia features a direct lateral offset and a 132-degree neck angle, which provides the ability to lateralize +5mm across the size range and enable independent adjustment of offset while maintaining leg length. Insignia utilized SOMA* to establish market leading femoral offset coverage to help recreate patient biomechanics.4-13†
*Based on 1,138 CT scans

Flexibility
Ease of insertion
Insignia features a low-profile shoulder, short stem lengths and distal lateral relief, which are designed to ease insertion and lateralization during muscle-sparing approaches.
Stryker’s femoral tray system is built for efficiency. One general hip instrument tray is compatible across three femoral stems (Insignia, Accolade II, and Exeter), allowing for minimal tray usage and cross-compatibility.
Stryker’s broach handles are available in straight, offset, extra offset and dual offset designs. These broach handles feature a lever to actively secure the broach. This design is meant to minimize potential toggle and allow for reproducibility of bone preparation.1 Each handle is fully compatible with Accolade II, Exeter and Insignia femoral systems.
The Insignia Hip Stem has been shown to provide a reproducible fit across a wide rangeof femoral anatomies14,15,16 while offering surgeons ease of use.15 Early clinical outcomes show low rates of all-cause revisions and reduced risk of femoral fractures.17-21
Mako SmartRobotics™ is designed to elevate surgeon control and confidence and optimize implant placement by combining 3D CT-based planning and AccuStop™ haptic technology.22
Mako with Insignia empowers surgeons to know more through CT -based planning.
