Osteotomy Plate Keyhole Design for Tibial Stability

The patent applies preliminary action by pre-positioning the osteotomy plate with keyhole drill guides and cutting guides before making the osteotomy cuts. The positioning guide is attached to the tibia first, establishing precise reference points and orientations for subsequent cutting operations. This preliminary setup ensures that the wedge-like opening is created with exact dimensions and orientation, minimizing deviations that could cause tissue trauma.

The patent uses intermediary devices including the positioning guide, cutting guides, and keyhole drill guides as mediators between the surgeon and the bone. These intermediary tools translate the surgical plan into precise physical actions, ensuring that cuts are made at exact locations and angles while protecting surrounding soft tissues from inadvertent damage during the osteotomy process.

The patent merges multiple functions into the osteotomy plate itself. The plate integrates fixation holes for screws, keyhole drill guide receptacles, and positioning features all in one device. This consolidation reduces the number of separate components and steps needed for stabilization while providing comprehensive fixation and guidance functions, thereby reducing procedural complexity compared to using multiple separate devices.

The osteotomy plate serves multiple functions simultaneously: it acts as a fixation device to stabilize the bone segments, a guide for drilling keyholes for additional fixation, and a positioning reference for the osteotomy cuts. This multi-functionality reduces the overall complexity of the stabilization system compared to using separate specialized devices for each function.
