Joint Implants TRIZ Cases
- Flexible Tension Fixation for Accurate Fracture Reduction
A two-implant tension system improves fracture approximation through bone tunnels while reducing surgical complexity and neurovascular risk.
- Expandable Hip Stem for Customized Femoral Canal Fit
Radially expandable hip stems adapt to femoral canals, improving fit and limiting subsidence.
- Knee Arthroplasty Implants With Porous Fixation and Position Verification
This case combines porous patella and tibial implants with guides and real-time tracking to improve fixation and placement accuracy.
- Monolithic Honeycomb Spinal Implant for Fixation Without Subsidence
Selective laser melting forms the honeycomb implant and round thread recess in one build, avoiding rework and subsidence.
- Deployable-Anchor Intervertebral Cages for Narrow Access and Strong Fixation
This case uses collapsible cages, deployable anchors, porous structure, and additive manufacturing to improve fixation and fusion.
- Layered Therapeutic Polymeric Implants for Sustained Local Antibiotic Release
This case layers antibiotic-loaded polymers to sustain local release while preserving implant mechanical properties.
- Acetabular Cup Augments With Guided Defect Preparation
A drill guide and matching void filler help fill irregular bone defects while limiting additional removal and supporting bone ingrowth.
- Adjusted-Stiffness Orthopaedic Implants to Reduce Bone Fracturing
Distinct porous regions and a variable-stiffness intermediate section tailor implant support while reducing stress that can fracture bone.
- Fixation Member Inserter With Simultaneous Vertebral Fastener Delivery
An impaction rod inserts multiple spinal fixation members at once, reducing surgical procedure time.
- Expandable Intervertebral Implant With Screw-Driven Height Adjustment
A carriage and ramp mechanism expands the implant after insertion, restoring disc space height while limiting tissue impaction.
- Bone Fusion Cage With Extendable Tabs for Secure Vertebral Placement
Preloaded graft material and deployable tabs help position a bone fusion cage securely between vertebrae with less slippage.
- Bone Cutting Box for Secure, Precise Graft Shaping
An adjustable holding plate and enclosed cutting box align and secure bone grafts for accurate surgical shaping.
- Articulating Vertebral Spacers for In-Situ Height and Lordosis Adjustment
This expandable spacer uses a shaft, collar, nut, and ramps to independently adjust posterior height and lordotic angle in situ.
- Intervertebral Implant Assembly With Rotational Screw Retention
Rotational connection screws secure the interbody implant while limiting translation.
- Ramped-Carriage Intervertebral Implant for Adjustable Disc Height
This case uses a compressed intervertebral spacer, screw actuator, and ramped carriage to restore disc height with controlled expansion.
- Expandable Implant Worm Gear for Controlled, Collapse-Resistant Fusion
A worm gear, ratchet, and spring locking mechanism control expansion and maintain implant position for stable intervertebral fusion.
- Infinitely Adjustable Augment-Angle Baseplate for Glenoid Alignment
Pivot-hinge adjustment replaces discrete augment angles, helping improve fit, alignment, and stability while reducing implant variety.
- Expandable Interbody Spacers for Precise Height and Lordotic Correction
Pivoting link members expand a compressed interbody spacer horizontally and vertically for support and lordotic correction.
- Disc-Shaped Bone Augment With Elastic Segments for Secure Fixation
A C-shaped skeletal augment uses elastic segmentation for compression, primary fixation, bone ingrowth, and controlled explantation.
- Trial Patella Component Kit for Sensor-Guided Joint Balancing
Sensors guide patella resection and soft-tissue balancing during knee replacement.
