Ankle Joints TRIZ Cases
- Pelvic Implant Placement Using Combined Anteversion Navigation
Navigation system guides cup and stem placement to achieve 30-45 degree combined anteversion, minimizing impingement caused by pelvic tilt variations.
- Subcutaneous Prosthesis Implant with Movable Joint for Load Distribution
A subcutaneous prosthesis implant features movable joint members that absorb axial and non-axial forces while maintaining natural bone orientation.
- Arthrodesis Apparatus with Depth Gauge and Guide System
A depth gauge stop mechanism prevents excessive penetration during arthrodesis, while a guide system ensures accurate alignment.
- Pivotable Lapidus Guide System for Metatarsal-Cuneiform Alignment
A pivotable guide system aligns metatarsal and cuneiform bones using integrated bone anchors and cutting guides.
- Cannulated Titanium Screw for Flat Foot Correction
A cannulated titanium screw with a conical head enables precise insertion through small incisions.
- Tibial Tray Extensions with Porous Proximal and Smooth Distal Zones
Segmented tibial tray extensions use sintered titanium foam for proximal fixation while maintaining a smooth distal surface to prevent bone overgrowth.
- Bone Implant Cutting Guide for Flatfoot Surgery Customization
A cutting guide system with aligned slots enables precise bone implant trimming during surgery.
- Resilient Joint Implant Shock Absorption
A resilient orthopedic implant absorbs shock through elastic deformation and inner chamber damping to restore natural joint motion.
- Force Sensor for Knee Ligament Balancing
An electronic force sensor replaces subjective assessment to balance ligament tension, ensuring stable prosthetic knee joints.
- Orthopaedic Implant with Integrated Dosing Reservoir
An orthopaedic implant integrates a reservoir and dosing mechanism to release medical substances directly at the surgical site.
- Anterior Resurfacing Talar Plate for Revision Ankle Surgery
A surgical plate with an anterior articulation portion resurfaces the talus bone to restore joint motion.
- Pyrolytic Carbon Orthopedic Implant with Porous Fixation
A pyrolytic carbon orthopedic implant incorporates a porous metal fixation portion to enhance bone integration.
- Modular Prosthesis Extensions for Revision Surgery
Segmented porous metal extensions on modular knee prostheses facilitate easier removal during revision surgery.
