• The purpose of this study – To provoke the attention for the concept
of orientation and rotation to orthopedic surgeons
– Demonstrate the practical guideline for deformity correction by affine geometry.
• 3 simulations– Simplified motion of shoulder joint using
affine geometry– Simplified cylinder model for deformity
correction of a long bone– Proximal femoral derotational
osteotomy(FDO) using 3D reconstruction model of femur
