“…Referring to the mapping method that Cole et al [5] and Armitage et al [6] described, we modified the fracture mapping methodology [7] and applied a similar method to the study of both-column fractures. The digitally imaged files (DICOM) were loaded into 3D Slicer (version 4.7.0; Boston, MA, USA), in which three-dimensional computed tomography reconstructions of hemipelvis were created through proper cropping and rotation.…”

Background The primary goal of this study was to create a frequency map of a series of surgically treated both-column fractures and to explore its implications on surgical management. Methods We used a consecutive series of 71 both-column fractures to create 3-dimensional reconstruction images, which were superimposed and oriented to fit a model hemipelvis template by aligning specific pelvis landmarks. Fracture lines were identified and traced to create a fracture map of both-column fractures. Then the possible clinical implications of fracture line map were explored. Results Fracture location is closely related to the distribution of fracture line. Of 71 fractures that met the criteria for inclusion, we found the most common pattern demonstrated by coexisting fracture lines. The anterior column was involved by 66% of the fractures extending obliquely from the anterior superior spine to the ischial spine, while 62% of the fractures involved the anterior column extending approximately vertically from the iliac crest to the acetabular roof. Additionally, 39% of the fractures involved the posterior column traversing posterior wall. Furthermore, the high fracture line intensity ( n = 65, 92%) formed a Y-shaped pattern, which highlighted the consistency of the patterns. Conclusions Surgically treated both-column fractures display very common patterns. The most common pattern is the low anterior column fracture in nearly two thirds of cases, the high anterior column fracture in three fifths of cases and the posterior column fracture with posterior wall involvement in nearly two fifths of cases. These study results may help surgeons to yield insight relevant to surgical approaches, reduction, fixation strategies and even implant design for both-column fractures.

“…Clinical assessment of patients with TL fractures can be challenging; therefore, diagnostic imaging methods such as the spine computed tomography (CT) often play an essential role in exact diagnosis and appropriate management [6,7]. With increasing concern over big data analytics, the distribution map of fracture lines (fracture mapping) based on 3D CT has also been widely used in orthopedic fields, including scapular fractures and tibial plateau fractures, to characterize fractures [8,9], which was initially described by Cole et al [10,11]. However, it has rarely been used in the study of spinal fractures such as thoracolumbar fractures.…”

Background Fractures of the thoracolumbar (TL) spine represent 90% of all spinal fractures, followed by cervical and lumbar spine fractures. This study aimed to create fracture maps of the traumatic thoracolumbar (TL) fracture vertebral body (T12-L2) through the use of CT mapping as a big data visualization method to reveal recurrent patterns and characteristics of traumatic TL fractures. Material/Methods A consecutive series of 174 fractured vertebrae (T12–L2) was used to create three-dimensional (3D) reconstruction images, which were superimposed and oriented to fit a model vertebral template by aligning specific bio-landmarks and reducing reconstructed fracture fragments. Fracture lines were found and traced to create a fracture map of the vertebral body. Results Our study consisted of 165 patients with an average age of 47 years. A total of 174 fractured vertebrae were collected, consisting of 59 T12 vertebral fractures, 60 L1 vertebral fractures, and 55 L2 vertebral fractures. Two-dimensional (2D) maps, 3D maps, and heat maps showed that the fracture lines tended to be concentrated in the upper third and anterior third of the vertebral body, as well as being distributed in annular wedges along the anterior and lateral sides of the vertebral body. When compared with T12, the distribution of fracture lines in L1 and especially in L2 was more scattered and disorganized. Conclusions Fracture maps revealed recurrent patterns and characteristics of the traumatic TL fracture vertebral body, which improves understanding of TL fractures, as well as helping to increase opportunities for follow-up research and aid clinical decision-making.

“…This provides previously unavailable mechanistic insights [8], more clearly illustrates the location and frequency of fracture lines, and helps to identify specific fracture patterns [9]. The two-dimensional or three-dimensional MT of fractures can also help surgeons to better understand the mechanical characteristics of these fractures, improving surgeons' preoperative diagnosis, preoperative planning, and execution of surgical strategies [10], [11]. The growing number of surgical applications MT affects makes it essential to analyze this new technology and to assess the value of present and potential applications.…”

Background Translational medicine (TM) is a bridge between basic science and clinical medicine by translating new knowledge, mechanisms and technologies generated by basic science research into new ways of preventing, diagnosing and treating disease. The purpose of this study is to systematically review the literature concerning the two-dimensional and three-dimensional mapping technology (MT) for fractures in orthopedics, to clarify what perspectives MT offers and the current challenges in TM. Methods A systematic review was conducted according to PRISMA guidelines. We systematically searched the PubMed, Scopus, IEEE Digital Library, Web of Science database and references of relevant studies, from the establishment of the database through December 2020, for any and all data regarding the application of fracture MT in orthopedics, (including upper limbs, lower limbs, spine, and pelvis). We then made a systematic summary of these research results. Results A total of 2777 articles were retrieved, and 28 articles met the inclusion criteria: 26 were retrospective studies of using fracture MT and 2 were prospective studies using of fracture MT. The application of fracture MT in orthopaedics was as follows: upper limbs (n=10, 35.71%), lower limbs (n=17, 60.71%), thoracolumbar spine (n=1, 3.58%). Article subjects included: how fracture mapping guided preoperative planning (n = 12, 42.86%); illustration of how the characteristics of fracture line distribution helped surgeons identify specific types of fractures (n=9, 32.14%); and how fracture MT illustrated fracture morphology and guided clinical treatment (n=7, 25.00%). Conclusion Today, we need a new generation of researchers: 'translational scientists' who are able to transfer ideas from basic research to clinical science. MT is a better technology to describe the morphological classifications of fractures compared to traditional methods, but its clinical application is still limited. Thus, much further research is needed to determine the potential advantages of this new technique in clinical application or practice. If possible, guidelines are needed to facilitate the development of MT with regard to the additional costs and time constraints required for the developing this technic.
