“…The points to be chosen are those that reference the most important aspects of the study. 4 There is no previous methodology on this subject. As we wanted to compare the overall area of the articular surfaces, we selected the four cardinal points of each one, an additional point between each cardinal point and two central points in each model.…”

“…[1][2][3] Thanks to the revolution in three-dimensional (3D) imaging and the different tools at our disposal, we can compare bone surfaces using standardized computerized processes. 4 For this study, we use the Hausdorff-Besicovitch method, which measures the morphological differences between two specific bodies in a 3D space and offers numeric analyses to quantify them. 5 This study investigates the possibility of using three different foot bones (calcaneus, cuboid bone, and lateral cuneiform bone) to replace the distal radius (DR).…”

Background Distal radius (DR) reconstruction due to high-energy trauma, degenerative processes, and oncologic resections can be a challenge when the articular surface is destroyed or resected. This study investigates the possibility of using the cuboid bone of the foot to replace the osteoarticular surface of DR. Purposes We compared the three-dimensional (3D) morphology of the articular surface of three foot bones with that of the DR to analyze which one would be the most suitable to replace it. Methods 3D bone models were created from a computed tomography (CT) scan database. The articular surfaces of calcaneus, cuboid bone, and lateral cuneiform bone were compared with that of the DR using the Hausdorff-Besicovitch morphometry analysis. Mean, maximum, and minimum differences were obtained and statistically analyzed. Results The cuboid bone had a mean overall area difference with the DR of 0.72 mm (standard deviation [SD], 0.03 mm). The lateral cuneiform bone showed 0.89 mm (SD, 0.08 mm). The calcaneus presented 1.04 mm (SD, 0.06 mm). The differences and the variability of the articular surface were statistically lower in the cuboid bone. Conclusion The articular surface of the cuboid bone has many similarities to the articular surface of the DR and had the most similarities to the DR of the foot bones study. The cuboid bone could be considered as a replacement for the DR in cases where there is a need for osteoarticular replacement or reconstruction. Further investigations are warranted. Clinical Relevance A vascularized transfer of the cuboid bone may be a suitable option to replace a DR given the anatomical similarities reported.

“…For both men and women, the left and right lower limbs maintain almost the same length, which is beneficial to maintain the balance of human bodies, and there is no significant difference between the left and right axes of the lower limbs under CT examination (Ferras-Tarrago et al, 2020). To facilitate the extraction of a femur centerline, images of the healthy side bone are used in this study.…”

Objective: Internal fixation with intramedullary nails is a gold standard for the treatment of femoral shaft fractures. However, both the mismatch between intramedullary nails and the medullary cavity and inaccurate positioning of entry points will lead to deformation of intramedullary nails after implantation. The study aimed to determine a suitable intramedullary nail with an optimal entry point for a specific patient based on centerline adaptive registration.Method: A homotopic thinning algorithm is employed to extract centerlines of the femoral medullary cavity and the intramedullary nail. The two centerlines are registered to obtain a transformation. The medullary cavity and the intramedullary nail are registered based on the transformation. Next, a plane projection method is employed to calculate the surface points of the intramedullary nail laid outside the medullary cavity. According to the distribution of compenetration points, an iterative adaptive registration strategy is designed to decide an optimal position of the intramedullary nail in medullary cavity. The isthmus centerline is extended to the femur surface, where the entry point of the intramedullary nail is located. The suitability of an intramedullary nail for a specific patient was calculated by measuring the geometric quantities reflecting the interference between the femur and nail, and the suitability values of all nails are compared and the most suitable one is determined.Results: The growth experiment indicated that the bone to nail alignment is indeed affected by the extension of the isthmus centerline, including the extension direction and velocity. The geometrical experiment showed that this method could find the best registration position of intramedullary nails and select the optimal intramedullary nail for a specific patient. In the model experiments, the determined intramedullary nail could be successfully placed into the medullary cavity through the optimal entry point. A pre-screening tool to determine nails which can be successfully used has been given. In addition, the distal hole was accurately located within 14.28 s.Conclusion: These results suggest that the proposed method can select a suitable intramedullary nail with an optimal entry point. The position of the intramedullary nail can be determined in the medullary cavity, while deformation is avoided. The proposed method can determine the largest diameter intramedullary nail with as little damage to the intramedullary tissue as possible. The proposed method provides preparation aid for internal fixation with intramedullary nails guided by navigation systems or extracorporeal aimers.

“…Moreover, patient-specific implants and instruments (PSI), such as surgical implants and surgical guides, can have advantages for patients with more severe pathologic conditions [10,11]. The most important precondition when using contralateral unaffected side bone data to repair the affected bone is similar left and right bone features [12,13].…”

Morphometric Evaluation of Detailed Asymmetry for the Proximal Humerus in Korean Population

Computer-assisted orthopedic surgery and patient-specific instruments are widely used in orthopedic fields that utilize contralateral side bone data as a template to restore the affected side bone. The essential precondition for these techniques is that the left and right bone features are similar. Although proximal humerus fracture accounts for 4% to 8% of all fractures, the bilateral asymmetry of the proximal humerus is not fully understood. The aim of this study is to investigate anthropometric differences of the bilateral proximal humerus. One hundred one pairs of Korean humerus CT data from 51 females and 50 males were selected for this research. To investigate bilateral shape differences, we divided the proximal humerus into three regions and the proximal humerus further into five sections in each region. The distance from the centroid to the cortical outline at every 10 degrees was measured in each section. Differences were detected in all regions of the left and right proximal humerus; however, males had a larger number of significant differences than females. Large bilateral differences were measured in the greater tubercle. Nevertheless, using contralateral data as a template for repairing an affected proximal humerus might be possible.
