Abstract
Providing a system for performing a CORA based leveling osteotomy. The system enables a uniform precise osteotomy and mechanical rotation of the proximal tibia concentric to the osteotomy and a means for fixing an osteotomy plate or brace while the system reduces the osteotomy through compression.
Claims1
A system for performing a CBLO, the system comprising:
- a central pivot pin, configured to be inserted at a central pivot location of a tibia;
- a bridge, fixed to the central pivot pin;
- a cannulated saw blade, fixed to the central pivot pin, for performing a complete curvilinear osteotomy of the tibia thereby segmenting the tibia into a proximal tibia section and a distal tibia section;
- a distal fixation foot configured to be fixed to the distal tibia section;
- a proximal fixation block configured to be fixed to the proximal tibia section and connected to a proximal block rotational handle through an angular tracking block;
- an angular track having an arching formation, and configured to be attached to the proximal tibia section;
- the angular tracking block being movably connected to the angular track;
- an angular scale representing degrees of rotation;
- and
- whereby the angular track is configured to be connected to the proximal tibia section to enable travel of the angular tracking block along the angular track for a mechanical control of the proximal tibia section while rotating the proximal tibia section in relation to the distal tibia section.
