Objective:
Design and construct a custom anatomical lower body skeletal model for use in a clubfoot research project with the following characteristics/tasks: |
|
 |
-
Scale adult medical image data to fit a 5 year old male anatomy.
-
Customize hip and knee joint shape to allow for normal anatomical movement (rotation, flexion/extension, adduction/abduction).
-
Blend two models (normal pelvis/femur/tibia/fibula medical image data with existing data from Ponseti training model*) to obtain a realistic clubfoot anatomy.
-
Design a fixture matching the pelvis anatomy to fixate the model to a frame of reference.
Customized Results |
-
STL model with true anatomical shape from pelvis to toes specified for Fused Deposition Modeling with ABS resin, including:
-
Spherical ball-and-socket hip joint.
-
Bolted hinge knee joint with slight lateral rotation.
-
Seamless transition to existing Ponseti training model* with 13 individually scaled bones of the foot.
-
Snap-fit design of the pelvis to the fixture.
