Method for creating a surgical resection plan for treating a pathological deformity of a bone

摘要

The invention relates to a method for creating a surgical resection plan for treating a pathological deformity of a bone having a rim bounding a substantially hemispherical cavity of a bone, comprising: -receiving a set of 3D medical images of said bone, -defining from said 3D medical images patient anatomical landmark data comprising a center of said substantially hemispherical cavity in a patient referential,a rim axis,a circumferential coordinate system assigned to said rim and a plurality of points located along the rim, -determining from said patient anatomical landmark data a 3D patient coverage curve comprising, in the circumferential coordinate system assigned to the rim, a plurality of points representing a coverage parameter of the bone with respect to the substantially hemispherical cavity at a plurality of points along the rim, -receiving reference data corresponding to a reference rim morphology, said data comprising a 3D reference coverage curve, -creating:. a 3D surface model of at least a part of the bone including the rim from said set of 3D images, and. a 3D reference rim morphology model from the 3D reference coverage curve, -computing and displaying a virtual resection of the bone onto the 3D surface model to simulate removal of over-covered bone portions.
