Wrist Joints TRIZ Cases
- Compliant Orthopaedic Joint Mechanisms for Wear-Free Mobility
Flexure-based joint members replace rigid articulating surfaces to restore natural compliance, reduce particulates, and improve implant longevity.
- Radiocarpal Wrist Implant With Cortical Plate Fixation and Mobility
Cortical bone plate fixation and minimal bone resection help wrist implants resist loosening while preserving natural radiocarpal motion.
- Metatarsal Arthroplasty Implant Placement With Minimal Bone Removal
Precise guides and inserter tools help place metatarsal arthroplasty implants with minimal bone removal and stronger fixation.
- Metatarsal Arthroplasty Implant Placement With Minimal Bone Removal
Precise guides and bone-sparing implant tools improve metatarsal arthroplasty fixation while reducing bone removal and surgical risk.
- Adjustable Osteotomy Wedges for Precise Mid-Foot Realignment
Adjustable wedges, trial implants, and arcuate distractors improve mid-foot fusion and alignment while preserving bone hinge integrity.
- Extramedullary Tibia Guidance Jig for Accurate Ankle Alignment
An adjustable C-bracket jig aligns the tibia, foot, and ankle for precise distal tibia reaming without bulky rigid foot holders.
- Ankle Replacement Alignment Arm for Precise Pin Placement
A joint-line referencing arm, pin tube guide, and alignment foot improve ankle implant alignment and reduce bone screw misplacement.
- Asymmetric Talar Bone Plate for Revision Alignment and Compression
An asymmetric talar bone plate uses an elongated screw hole and tapered head to improve revision alignment, compression, and fixation.
- Curved Toe Implant Fixation for Stable MTP Joint Motion
A curved bearing surface, porous fixation, and non-porous barrier help restore MTP joint motion while reducing loosening, subsidence, and failure.
- Talar Dome Implant Clamp for Stable Ankle Arthroplasty Insertion
A pivoting clamp grips talar dome implants and trials securely, cutting insertion time while improving stability in ankle arthroplasty.
- Patient-Specific Ankle Alignment Guide for Precise TAR Bone Resection
Customized tibial and talar guide components hold the ankle in a preselected position to improve resection accuracy and implant alignment.
- Calcaneal Facet Repositioning With Patient-Specific Osteotomy Guides
Patient-specific guides and implants make calcaneal cuts predictable, reposition facets safely, and reduce tissue damage and recovery time.
