## Key points

- Intertrochanteric fractures are a common and serious injury in orthopaedics, with high morbidity and mortality rates.
- A map projection technique was proposed to visualize complex 3D fracture lines associated with these injuries.
- The proposed method preserves the 3D proximal femur surface and structure while mapping high-dimensional information into a 2D parametric space.
- The method was tested on radiographs acquired by CT scan from 100 patients of different ages and genders.
- The map projection representation is more efficient and rich in information visualization than conventional heat map techniques, enabling accurate identification of the most probable fracture region based on fracture probability at any location in the 2D parametric space.
- Age and gender were found to have significant influences on intertrochanteric fracture frequency and fracture line distribution.
- Patient demographics should be considered when diagnosing and treating intertrochanteric fractures.
- Advanced visualization techniques can improve our understanding of complex orthopaedic injuries like intertrochanteric fractures, providing clinicians with more accurate diagnostic tools for improved patient outcomes in orthopaedics.

## Summary

Intertrochanteric fractures are a common and serious injury in orthopaedics, with high morbidity and mortality rates. To address the challenge of visualizing complex 3D fracture lines associated with these injuries, a team of researchers proposed a map projection technique that maps high-dimensional information into a 2D parametric space while preserving the 3D proximal femur surface and structure. The proposed method was tested on radiographs acquired by CT scan from 100 patients of different ages and genders. The results showed that the map projection representation is more efficient and rich in information visualization than conventional heat map techniques. This enables accurate identification of the most probable fracture region based on fracture probability at any location in the 2D parametric space. Furthermore, age and gender were found to have significant influences on intertrochanteric fracture frequency and fracture line distribution. These findings emphasize the importance of considering patient demographics when diagnosing and treating intertrochanteric fractures. This research demonstrates how advanced visualization techniques can improve our understanding of complex orthopaedic injuries like intertrochanteric fractures, providing clinicians with more accurate diagnostic tools for improved patient outcomes in orthopaedics.
