## **DoggyBone – Veterinary Corrective Osteotomy Tool**

Hi everyone,

first of all, I would like to thank the Slicer community for providing such a powerful platform and for all the knowledge and support available through this forum.

I would like to introduce **DoggyBone** , a veterinary 3D Slicer module intended for the planning of **corrective osteotomies of the femur and tibia in dogs**.

The project is based on an original 3D Slicer module developed by **Dr. Juliette Burg at LMU Munich** as part of her doctoral research. Her original work provided tools for the measurement and analysis of femoral and tibial axes.

Building on this foundation, I have modified and expanded the module considerably. In particular, I have worked on:

- adapting and improving the **user interface and workflow** ,
- extending the original bone-axis measurements into an **interactive corrective osteotomy planning workflow** ,
- implementing tools for planning corrections of the **femur and tibia** , and
- adding functionality for the **generation of patient-specific surgical guides** based on the planned correction.

The additional programming and development were carried out by me **with the assistance of Claude** , particularly for implementing and refining the Python code.

The module is currently still under development, and I am sure there are many aspects that could be improved—both from a programming perspective and regarding integration into the usual 3D Slicer workflow.

I would therefore be very grateful for **feedback, suggestions, criticism, or technical input from experienced Slicer developers and users**. In particular, I would appreciate advice regarding code structure, robustness, UI design, and the implementation of the osteotomy and patient-specific guide workflow.

My aim is to develop DoggyBone into a practical and reliable open tool for **veterinary orthopedic planning** , while keeping it well integrated with the philosophy and existing tools of 3D Slicer.

Thank you very much in advance for taking the time to have a look at the project and for any feedback you may have.

Best regards,  
**Matthias**
