“…Fracture map, first proposed by Armitage et al [4] in 2009, is a method of superimposing the fracture lines of multiple fracture models on a normal model through CT three-dimensional reconstruction, and visually displaying the shape of this type of fracture. Previous researches have been conducted to investigate the fracture morphology by using 2D fracture map, including tibial plateau fracture [5], pilon fracture [6], and intertrochanteric fracture [7]. However, little work has been done on the distal humeral fracture.…”

Background Distal humerus fractures (DHFs) constitute one-third of elbow fractures approximately. In this study, we aim to define and analyze the fracture lines and morphological features of DHFs using mapping technique. Methods One hundred and two DHFs were retrospectively reviewed. All the computed tomography (CT) data were used to manually reconstruct and virtually reduce the DHF fragments to fit a standard 3D model. Smooth curves were depicted accurately onto the surface of the template to represent the fracture lines. All the curves were overlapped onto the model to create the 3D fracture map and heat map. Results Our analysis was based on 102 CT images of DHFs, contributed by 59 male and 43 female patients (mean age, 46 years; range, 18-93 years), and included 15 type A, 25 type B, and 62 type C fractures. On mapping, the hot zones were located in the radial fossa, coronoid fossa, olecranon fossa, and the external part of the trochlear. Conversely, the cold zones were noted in medial condyle, the medial side of the trochlear, and the anterolateral area on the supracondylar ridge. Conclusions Our study firstly shows the fracture lines and morphological features of distal humeral fractures by three-dimensional mapping technology. Distal humerus fracture lines are characteristic and highly related to the micro-architecture difference of distal humerus, which may provide some guidance for the treatment plan selection and surgical fixation design.

“…Yao et al [11] used 3D mapping to demonstrate the typical pattern of fractures and verify the rationalization of classi cation. This fracture mapping improves our understanding of fracture patterns and morphology [12,13]. We consider that 3D mapping would reveal more detailed information than previous X-ray and CT.…”

Background: To determine the pattern of intra-articular calcaneal fractures (ICFs) by a three-dimensional (3D) mapping and determine whether there were consistent fracture patterns and comminution zones. Methods: Sixty-seven patients with ICFS by CT scan were included. The calcaneal fractures fragments in CT were multiplanar reconstructed and virtual reduced. 3D heat mapping was subsequently created by graphically superimposing all fracture lines onto a standard calcaneal template.Results: The cohort included 26 (38.8%) left calcaneal fractures, 27 (40.30%) right calcaneal fractures, and 14 (20.9%) cases with bilateral fractures. Comminuted fractures accounted for 92.5%. Sagittal 3D mapping shows that the fracture line is mainly concentrated at the critical angle of Gissane and extending rear to the posterior of the tuberosity of the lateral wall and the anterior of the medial process of the calcaneus tuberosity but with more significant variation in the medial wall. The average angle of fracture lines concerning the long calcaneal axis (LCA) was 29.1°and 19.2° in the lateral and medial walls. Axial 3D mapping shows that fracture lines were primarily concentrated in the anterior area to the posterior joint facet and extending along the rear joint facet and calcaneus sulcus to the posteriorly of the tuberosity. The mean angle of fracture lines concerning the LAC was 11° in the axial wall. Conclusion: The data provided elucidated that ICFs have consistent characteristic fracture patterns and comminution zones. This study provides visual guidelines for understanding fracture morphology, which may assist with fracture classification, preoperative planning, development of fixation concepts.

“…Technologies for image recognition have tremendously aided in the diagnosis and treatment of intertrochanteric fractures. 30 Elderly individuals with hip pain, dysfunction, and deformity are at risk for femoral neck fractures. Surgery is the best option for treating these fractures because non-union of the fracture and avascular necrosis of the femoral head are potential outcomes.…”

Complex medical data can be extracted using artificial intelligence, a branch of computer science. Their capacity to identify meaningful relationships within a data set can be applied in a variety of therapeutic settings for outcome prediction, diagnosis, and treatment. Artificial intelligence in medicine is developing swiftly. Artificial intelligence-powered medical technology is fast becoming practical clinical practice-related solutions. The increasing amounts of data generated by mobile monitoring sensors found in wearables, smartphones, and other medical equipment can be handled by machine learning algorithms. The use of Artificial Intelligence (AI) in many medical professions is discussed in this illustrative article from the perspectives of seven distinct fields: machine learning, intelligent robotics, image recognition technology, expert systems, artificial neural networks, and evolutionary computation. Additionally, it covers AI's prospective and current applications in medicine.
