Finger Joints TRIZ Cases
- Two-Component Interphalangeal Implant with Detent Arm for Hammer Toe Correction
Segmenting the implant into press-fit components prevents rotation and reduces non-union rates in hammer toe surgery.
- Flexible Intramedullary Stem Reduces Stress Shielding
Hollow frustoconical rod matches bone elasticity, resolving strength-adaptability trade-offs to minimize stress shielding and promote osseointegration.
- Inverted Concave Humeral Surface Shoulder Prosthesis
Resecting the humerus to create a concave articular surface eliminates scapular interference during adduction and prevents implant subsidence.
- Unitary PEEK Intramedullary Stem for CMC Joint Implants
A unitary PEEK intramedullary stem integrates the ball-and-socket articulation directly into the implant body.
