“…Fracture mapping can record the size, shapes, numbers, and orientations of fracture fragments, and help surgeons determine the optimal treatment (5). To date, fracture mapping has been applied to scapular, tibial, hip, and acetabular fractures (6)(7)(8)(9)(10)(11). However, there have been no reports concerning fracture mapping for the treatment of calcaneal fractures.…”

Background: Intra-articular calcaneal fracture remains challenging to manage. Computed tomography and fracture mapping are useful for the diagnosis and treatment of calcaneal fractures. The aim of the present study was to characterize calcaneal fracture patterns using fracture mapping.Methods: Sixty-two calcaneal fractures were retrospectively included in the study. For each case, the fracture was simulated reduction manually. The fracture lines and zones of comminution were graphically superimposed onto an intact calcaneal template to identify fracture patterns. Major fracture lines and comminution were assessed by focusing on the posterior joint facet, medial wall, lateral wall, sustentaculum tali, and anterior process.Results: The fracture lines were mostly concentrated on the area anterior to the posterior joint facet and extended medially. The longitudinal lines ran posteriorly from the angle of Gissane, and separated the sustentaculum tali and medial wall from the calcaneal tuberosity. In the lateral wall, the fracture lines extended posteriorly with some branches to the bottom of the calcaneus. No fracture lines passed through the sustentaculum tali. Fracture lines of the posterior tuberosity and anterior process were rare.Conclusions: Calcaneal fracture lines follow characteristic patterns, which are closely related to the bone structure and fracture mechanism. These fracture patterns will aid clinicians choose surgical approach and fixations in the treatment of calcaneal fractures.

“…This technology directly reveals the morphological characteristics of the fracture line and provides a novel method for fracture diagnosis and classification, treatment scheme selection, internal fixation design, fracture prone site statistics, and fracture standardized model formulation. Fracture mapping technology has so far been applied to scapular [ 9 ], distal tibial [ 17 ], ulnar coronoid process [ 18 ], tibial plateau [ 19 ], radial head [ 20 ], intertrochanteric [ 21 ], Hoffa [ 12 ], acetabular [ 22 , 23 ], lumbar [ 11 ], posterior malleolus [ 24 ], and calcaneal fractures [ 10 ].…”

Background This study aimed to evaluate Sanders type 2 calcaneal fractures in 197 patients from a single center using the 3D (three-dimensional) CT (computed tomography) mapping method. Material/Methods A consecutive series of 197 Sanders type 2 joint depression calcaneal fractures was used. The segment and split functions were used to create each calcaneal fragment using Mimics Research 20.0 software. The fracture fragments were reduced in 3-matic Research 12.0 software. In the E-3D Medical 18.01 software, after superimposing the fractured calcaneus entity with the calcaneus template, we drew the fracture line on the template. Finally, the heatmap was obtained by fracture statistical analysis function. Simultaneously, the distribution of the fracture lines in the anterior part of the calcaneus (APC) and middle talar joint was recorded. Results There were 109 cases of Sanders type 2A, 46 cases of Sanders type 2B, and 42 cases of Sanders type 2C. Based on the data, we drew the characteristic fracture map of type 2A 2B and 2C. This study found that the most common types of Sanders type 2A in APC and middle talar articular surface are type AC and type AD. In Sanders type 2B, the most common type is type AC, and in Sanders type 2C it is type ACD. Conclusions The findings from this study showed that 3D CT imaging and reconstruction of the calcaneus was a useful diagnostic method to evaluate and classify joint depression calcaneal fractures. The calcaneal fracture map can be used to guide surgical planning and optimize the design of internal fixation.

“…According to related studies, the shape trend of the fracture line of the fracture is related to the effect of external force. According to the shape of the fracture line, it contributes to the type of external force [ 13 ]. The transverse fracture line is generally a traction fracture, oblique behavior push fracture, external rotation force generally leads to helical fracture, and the fracture line of the generalized fibula after supination and external rotation is laterally anterior to posterior.…”

Objectives: To study the value of X-ray analysis method of ankle fracture based on injury mechanism to improve the imaging diagnosis level of ankle fracture. Methods: This study was conducted from January 2016 to December 2019. It included 105 cases of fractures caused by sprained ankle joints. Their age was between 21-81 years with an average of 49.5 years, The traditional X-ray analysis method (Group-A) and the injury mechanism-based ankle fracture X-ray analysis method (Group-B) were used to analyze X-ray image data. Group-B also performed Weber classification and Lauge-Hansen classification on cases. Installment. Results: Of the 105 patients with ankle fractures, 97 patients in Group-B were able to make Lauge-Hansen classification. Of these 97 ankle fractures, 137 were found in Group-A, and 158 were found in Group-B. The wrong diagnosis of fracture in Group-A was 18%, and the wrong diagnosis of fracture in Group-B was 0.5%. There was a statistically significant difference between the two groups (P <0.05). Conclusion: The X-ray analysis method of ankle fractures based on injury mechanism can effectively improve the detection rate of hidden ankle fractures and high fibular fractures, and reduce the missed diagnosis, which is superior to the traditional X-ray analysis methods. At the same time, Weber classification, Lauge-Hansen classification and staging can be made for most cases, which is conducive to guiding clinical treatment. doi: https://doi.org/10.12669/pjms.37.6-WIT.4841 How to cite this:Meng S, Tong W, Han S.
