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.

Abstract: Understanding intertrochanteric fracture distribution is an important topic in orthopaedics due to its high morbidity and mortality. The intertrochanteric fracture can contain high-dimensional information including complicated 3D fracture lines, which often make it difficult to visualize or to obtain valuable statistics for clinical diagnosis and prognosis applications. This paper proposed a map projection technique to map the high-dimensional information into a 2D parametric space. This method can preserve the 3D proximal femur surface and structure while visualizing the entire fracture line with a single plot/view. Using this method and a standardization technique, a total of 100 patients with different ages and genders are studied based on the original radiographs acquired by CT scan. The comparison shows that the proposed map projection representation is more efficient and rich in information visualization than the conventional heat map technique. Using the proposed method, a fracture probability can be obtained at any location in the 2D parametric space, from which the most probable fracture region can be accurately identified. The study shows that age and gender have significant influences on intertrochanteric fracture frequency and fracture line distribution.
