The AnyBody Modeling System has been used to solve a range of problems related to hips: It has been used to quantify the risk of edge loading, evaluating the consequences of surgical procedures, and to answer many other questions related to hip arthroplasty.
Examples:
- Edge load quantification
- Acetabular implant stability
- Hip contact forces during gait
- Physiological realistic loads for activities of daily living
- Lumbar loads dependency on spinopelvic sagittal alignment
- Hip surgery procedure influence on hip reaction forces
- Realistic loads and motions for wear simulations
Examples of input and output for a total hip arthroplasty model
Input:
- Implants CAD files (STL)
- Implant positioning data
- Bone CAD files (STL)
- Anthropometrics data
- Motion data and ground reaction force

The steps to model this can be the following
- Reproduce the activity, e.g. walking, using your own data or an existing AnyBody model
- Custom scale the related bones using built-in morphing techniques (AnyFunTransForm3D)
- Run the inverse dynamic model (AnyBodyStudy)
- Evaluate the output: joint reaction forces, muscles, and ligament forces
