Osteotomy Plate Wedge Opening Bone Alignment

The patent applies preliminary action by using a positioning guide and apex pin to pre-establish the exact location and orientation of the osteotomy cut before actually making the cut. The positioning guide is inserted into the tibia and the apex pin is positioned at the apex of the wedge, allowing the surgeon to accurately mark and then make the osteotomy cut at the predetermined location with minimal deviation, thereby improving precision while reducing unnecessary trauma to surrounding tissues.

The patent uses an intermediary approach by introducing a positioning guide as a mediator tool between the surgeon and the tibia. This positioning guide serves as a template that transfers the planned osteotomy geometry to the actual bone surface, enabling precise wedge-like opening creation without directly manipulating the bone with excessive force or precision tools that could cause trauma. The guide acts as a buffer that ensures accuracy while minimizing direct tissue damage.

The patent applies preliminary action by pre-positioning the apex pin at the apex of the wedge-like opening before manipulation occurs. This apex pin serves as a predetermined anchor point that will maintain the reoriented bone segments in place during healing. By establishing this reference point in advance, the surgeon can manipulate the tibia to open the wedge and achieve the desired reorientation, while the pre-positioned apex pin ensures stability is maintained throughout the healing process.

The patent uses the apex pin as an intermediary element that mediates between the manipulated bone segments and the healing process. The apex pin is inserted into the apex of the wedge-like opening and serves as a stable reference that maintains the spatial relationship between the upper and lower portions of the tibia during manipulation and healing. This intermediary structure allows the bone to be reoriented while providing continuous stability without requiring complex fixation mechanisms.
