TrueGrid® Meshes of Leg Bones and Implants
Dr. Donald Bartel is a Professor in the Department of Mechanical and
Aerospace Engineering at Cornell University and Senior Scientist with
the Laboratory for Biomedical Mechanics and Materials at the Hospital
for Special Surgery in NYC. For those who wish to learn more about these
organizations, their personnel and research,
the Biomedical Mechanics program
with the school of Mechanical and Aerospace Engineering Dept. at Cornell
University has their own well organized web site.
For many years Dr. Bartel has studied the biomechanics and performance of
bone-implant systems, focusing primarily on the hip and knee. These images
are from current research on secondary fractures resulting from internal
fixation of femoral neck fractures and the role of stem augmentation in
constrained condylar knees.
A growing desire for statistically based analyses requires multiple
physical models that emphasize some of Truegrid's strengths. Its
morphing and projection-based geometry creation, flexibility with
surfaces and batch processing capabilities allow for efficient creation
of comparable finite element meshes for different bones and implants.
The images of the tibia show two implants for two bones created with
essentially the same truegrid session file and minimal analyst
input.
