Internal Osteosythesis TRIZ Cases
- Small-Bone Fixation Plate With Buttress-Guided Osteotomy Stability
An offset buttress plate is attached before osteotomy to preserve surgical visibility, guide the cut, and stop the bone head from swiveling.
- Polyaxial Bone Anchoring Device With Axial Pressure-Member Locking
An axially movable pressure member locks or releases the bone-anchor head, enabling rod adjustments without continuous instrument attachment.
