Software for use with deformity correction

A method of generating a correction plan for correcting a deformed bone comprising the steps of:

• displaying on a visual medium a first model of the deformed bone in a first plane, the first model of the deformed bone having a position and orientation on the visual medium;
• overlaying a model bone having a first configuration on the first model of the deformed bone in the first plane and manipulating a position and orientation of the model bone into a second configuration being substantially similar to the position and orientation of the first model of the deformed bone in the first plane;
• displaying on the visual medium a second model of the deformed bone in a second plane, the second model of the deformed bone having a position and orientation on the visual medium;
• overlaying the model bone in the second configuration on the second model of the deformed bone in the second plane and manipulating the position and orientation of the model bone into a third configuration being substantially similar to the position and orientation of the second model of the deformed bone in the second plane;
• projecting the model bone in the third configuration onto a three dimensional axis;
• displaying a model of a first fixation ring having a first configuration and positional data corresponding to a position and orientation of the model of the first fixation ring with respect to the three dimensional axis;
• manipulating the positional data corresponding to the position and orientation of the model of the first fixation ring into a second configuration relative to the model bone being substantially similar to a position and orientation of a first fixation ring relative to the deformed bone.
