Educational use only

OrthoAnimate modules demonstrate concepts and support teaching. They are not validated patient-specific planning or clinical decision-support systems.

Imaging & projection anatomy

See how 3D anatomy creates the radiograph.

One shared imaging environment for learning projections across orthopaedic anatomy.

Imaging · Projection Anatomy

3D Radiograph Lab

Manipulate reviewed CT-derived anatomy beside an attenuation-based simulated radiograph. Choose hip, pelvis, or lumbar-spine tracks; learn how projections are obtained; judge image adequacy; and test view recognition and positioning.

Linked 3D anatomy and simulated radiograph
Hip, pelvis, and lumbar-spine tracks
Acquisition and image-quality guidance
View identification and positioning quizzes

Rotate the model, change the projection, and connect the 2D image to the anatomy that creates it.

Spinopelvic Motion Lab

Explore how lumbar motion, pelvic rotation, and hip flexion change functional acetabular orientation across standing, sitting, and extension. Compare flexible, stiff, stuck-standing, stuck-sitting, and hypermobile patterns with implant settings held constant.

Animated sagittal biomechanics

Hip–spine classification
THA stability implications

Designed as a resident teaching model, with editable assumptions and explicit educational limitations.

TKA Sagittal Balance Lab

Work through the flexion–extension gap matrix and see how bone cuts, femoral sizing, posterior slope, constraint, inserts, and augments affect sagittal balance.

Nine-pattern gap matrix
Animated lateral knee
Irreversible cut model
Graded quiz cases

Built around conventional mechanical alignment and measured resection, with assumptions and limitations stated in the module.

About the project

A focused platform for interactive orthopaedic teaching.

OrthoAnimate is owned and operated by OrthoAnimate LLC and offers a clinician-developed, evidence-informed collection of purpose-built web applications intended to make difficult orthopaedic concepts easier to visualise, manipulate, and discuss.

Each module defines its educational scope, makes important assumptions visible, and links to the literature supporting its model. A published editorial and corrections process governs clinical review, feedback, and material updates.
