Stryker IMN Platform Features
Advanced Locking Screws
Designed with oversized threads that engage with the internal threads on the T2 Alpha/Gamma4 nails, helping to limit relative motion between nail and screw while maintaining bicortical purchase. Designed to reduce toggle up to 50% compared to T2 locking screws. May be preferred in instances when axial stability is desired.
Image Description: Two screws with prominent threads are shown, one with a blue tip.
SOMA Designed
Stryker Orthopedic Modeling and Analytics (SOMA) designed nails, analyzing over 6,000 CT scans of diverse patient populations across age, gender, and ethnicities to achieve a better fitting implant.
Image Description: A series of human femurs and nails, illustrating different lengths and shapes.
Length Dependent Radius of Curvature
Mismatch of the ROC of the femur and nail is a key factor in potential anterior femoral cortical perforation, as has been confirmed in multiple studies. All of our long nails change curvature dependent on nail length, designed to create the best fitting implant.
Guided Targeting
T2 Alpha and Gamma4 aims to provide surgeons with a reproducible and consistent procedure for distal locking screws. Designed to improve accuracy to reduce the risk of nail damage (titanium implants may fail early at regions with high stress concentration - notch sensitivity).
Image Description: A surgical targeting device is shown attached to a nail, with a close-up of the device's components.
A Gamma3 clinical study showed 64% shorter fluoroscopy time than freehand locking method of perfect circles.
Controlled Compression
Amount of compression depends on specific indication used in the T2 Alpha platform. Retrograde and GT/PF nails achieve up to 10mm, Tibia up to 7mm.
Internal Compression
Using an internal compression screw and driver to apply controlled compression on the proximal locking screw.
External Compression
Using a compression driver device to engage the internal threads on the nail before placing the last locking screw.
Gamma4 Short, Intermediate, and Long Femur Nails
Image Description: A Gamma4 nail with labels indicating features like 'pre-inserted and cannulated set screw', 'working length equivalent to Gamma3® 180mm', 'medial bevel for nail insertion', 'beveled proximal end', '5mm shorter, less protrusion', and 'Ø5mm Locking Screw oblong hole'.
1. SOMA Designed Nail
Featuring shortened proximal body, chamfered distal tip, with a pre-inserted set screw.
2. Precision Pin
3.7x more resistance to pullout compared to a 3.2 K-wire. 66% reduction in skiving compared to a K-wire.
Image Description: A precision pin and a drill bit with a screw thread are shown, along with a diagram illustrating the pin's engagement.
3. Streamlined Workflow
All of our nails work out of one IMN Basic Set, simplifying cross compatible instrumentation. Reduced inventory. Cross compatible disposables.
