Abstract
Methods for understanding external and internal anatomy of bones through the use of imaging data and 3D modeling to facilitate the design of anatomically correct plates, devices and implants are disclosed. In one aspect the method results in an implant or plate that includes at least one curved surface wherein a contour of the at least one curved surface corresponds to an anatomic shape of a subject. The anatomic shape of the subject being determined based on an image of the bone.
Claims20
A device for treating a fracture in a bone, the device comprising:
- a first section having a first longitudinal axis;
- a second section having a second longitudinal axis;
- the first section being connected to the second section at a base of the second section thereby defining a first junction between the first section and the second section;
- and
- the first junction forming a transition portion dimensioned to provide a curvature connecting the first section to the second section,
- wherein the device is an intramedullary nail.
A method for manufacturing an orthopedic implant for repairing a part of a bone in a subject, the method comprising:
- forming the implant to include at least one bend wherein the at least one bend corresponds to an anatomic shape determined by
- (i) obtaining an image of the bone from at least one viewing plane;
- (ii) orienting on the image a first reference line indicating a maximum width of a feature of the bone from a first border of the bone to an opposite second border of the bone;
- (iii) orienting on the image a second reference line perpendicular to the first reference line and extending from a midpoint of the first reference line to an edge of the bone indicating a length of the feature of the bone;
- (iv) orienting on the image a third reference line indicating a length from a centerline of the bone to the midpoint of the first reference line;
- and
- (v) determining an angle between the third reference line and the second reference line to determine the at least one bend of the implant.
