“…The DICOM files were imported into Materialize Mimics (Materialize, Leuven, Belgium, version 21), using a lossless compression technique, to create the 3D digitized models. Materialize Mimics is medical image processing software extensively used in neurology, cardiology, and orthopedics [8][9][10]. First, a "bone mask" was created to isolate the pixels of bony tissue, then the segmenting tool in Mimics was used to construct the reflected left side and the right side of pelvic models, followed by "edit mask" to eliminate the pixels of surrounding soft tissue and noise, and to remove the pixels of the spine, femurs, and sacrum, then "region grow" to create two isolated masks, which represented one for each side of the pelvis, "calculate part" to construct 3D models, and "mirror" to reflect the left side model across the sagittal plane (defined by the YZ plane in the image coordinate system).…”

Objectives This study aimed to investigate the symmetry of the Chinese pelvis. Methods Computed tomography scan images of each of 50 Chinese pelvises were converted to 3D models and the left sides of the pelvises were reflected on Mimics software. Then, the reflected left side model was aligned with the right side using the closest point algorithm function of Geomagic software to perform symmetry analysis. The volume and surface area of either side of the pelvises were also calculated. The mean standard deviation (SD), the mean percentage of permissible deviations within the ±2 mm range, the percentage differences in volume and surface area were measured to compare pelvic symmetry. In addition, the distribution of pelvic bilateral symmetry associated with both age and sex were compared. Results The mean SD was 1.15 ± 0.16 mm and the mean percentage of permissible deviations was 90.82% ± 4.67%. The deviation color maps showed that the specific areas of asymmetry were primarily localized to major muscle or ligament attachment sites and the sacroiliac joint surfaces. There was no significant difference between the bilateral sides of the pelvis in either volume or surface area. Additionally, no difference in any indexes was exhibited in relation to sex and age distribution. Conclusion Our results demonstrated that the pelvis has high bilateral symmetry, which confirmed the potential of using contralateral pelvic models to create fully patient‐specific and custom‐made pelvic implants applicable for the treatment of fracture and bony destruction.

Background The surgical management of acetabular fractures is challenging, and although new minimally invasive surgical approaches are being developed, the optimal surgical approach is still under discussion. We compared the clinical and radiographic findings of two surgical approaches for acetabular fractures: the lateral rectus approach (LRA) and the ilioinguinal approach (IA). Methods A consecutive cohort of 42 patients treated by a single surgeon using the LRA or IA from June 2015 to December 2018 with displaced acetabular fractures with a minimum 1-year clinical and radiographic follow-up were included. Clinical data were reviewed for fracture pattern, time to surgery, operative time, blood loss, quality of reduction, and perioperative complications. Fracture reduction quality was evaluated according to the Matta criteria. The Merle D’Aubigne-Postel and Harris Hip Score (HHS) were used for hip function outcomes. Results The complications, fracture reduction quality, Merle D’Aubigne-Postel score, and HHS were not significantly different between the approaches. There were statistically significant differences in the mean operative time (P = 0.003), intraoperative blood loss (P = 0.012), wound drainage (P = 0.031), and blood transfusion rate (P = 0.005) between the lateral rectus approach and the ilioinguinal approach. Conclusion Compared with the ilioinguinal approach, the lateral rectus approach is promising, especially for fractures in the quadrilateral area. The approach benefits fracture exposure, reduction, and fixation, thus shortening the operative time and reducing intraoperative bleeding.
