“…Regarding material properties, a majority of models were stated as being linear elastic (Tables 1a,1b,1c), and only three models were nonlinear (Anderson et al, 2004;Eichenseer et al, 2011;Lee et al, 2017). Isotropic material properties form the majority of the existing modeling approaches, whereas only four studies used non-isotropic material parameters (Anderson et al, 2004;Hao et al, 2011;Hu et al, 2017;Shi et al, 2014).…”

“…Mechanisms involved in injury have been the focus of the studies by Böhme et al (2014), Lei et al (2015) and Sztrinkai et al (2014). Surgical stabilization for the treatment of pelvic injury have been addressed by many studies Bruna-Rosso et al, 2016;Fu et al, 2014;García et al, 2000;Lee et al, 2017;Wang et al, 2013;Zhang et al, 2014;Zhao et al, 2012). For this purpose, metal plates, screws, sacral bars and external fixators were included in models.…”

A feasible and optimal axis of biomechanical and anatomic significance in axial lumbosacral interbody fusion (AxiaLIF) was designed. Using the image dataset of an adult volunteer, two groups of finite element (FE) models of the AxiaLIF, lumbosacral anterior column fixation (ACF) models and middle column fixation (MCF) models with different bone graft fusion degrees, were prospectively established, and their biomechanical differences were comparatively predicted. In addition, 3D reconstruction was performed by retrospectively collecting CT data from pelvises in 60 adult cases. Their anatomic parameters relating to two groups of models were digitally measured and statistically compared. Numerical analysis revealed that the load and the maximum stress on the screw as well as the maximum stress difference between the screw and peripheral tissues in the MCF model were reduced compared with the ACF model. These indices of both models all decreased markedly in response to the increase in the disc fusion degree. Statistical analysis revealed that the effective fixed length of the sacrum in the MCF model was increased compared with the ACF model (P < 0.05). The surgical dissection distance of presacral vessels and nerves from the axis to sacrum of the MCF model was reduced compared with the ACF model (P < 0.05). The feasible and optimal axis of biomechanical and anatomic significance of the AxiaLIF is similar to the axis of the MCF model. Disc bone graft fusions plus axial screw fixations of middle column could strengthen the biomechanical stability of the AxiaLIF model. Clin. Anat. 32:337-347, 2019.

“…The aim of the osteosynthetic stabilization of pelvic ring injuries is the recreation of stability of the pelvic ring. The stability of the pelvic ring can be assessed by using the Tile-classification, where the integrity of the posterior pelvic ring is decisive for the stability of the entire pelvic ring [6]. Therefore, especially, Tile B or C injuries require surgical stabilization.…”

Associated abdominal injuries do not influence quality of care in pelvic fractures—a multicenter cohort study from the German Pelvic Registry

et al. 2020

Background: Pelvic fractures are rare but serious injuries. The influence of a concomitant abdominal trauma on the time point of surgery and the quality of care regarding quality of reduction or the clinical course in pelvic injuries has not been investigated yet. Methods: We retrospectively analyzed the prospective consecutive cohort from the multicenter German Pelvic Registry of the German Trauma Society in the years 2003-2017. Demographic, clinical, and operative parameters were recorded and compared for two groups (isolated pelvic fracture vs. combined abdominal/pelvic trauma). Results: 16.359 patients with pelvic injuries were treated during this period. 21.6% had a concomitant abdominal trauma. The mean age was 61.4 ± 23.5 years. Comparing the two groups, patients with a combination of pelvic and abdominal trauma were significantly younger (47.3 ± 22.0 vs. 70.5 ± 20.4 years; p < 0.001). Both, complication (21.9% vs. 9.9%; p < 0.001) and mortality (8.0% vs. 1.9%; p < 0.001) rates, were significantly higher. In the subgroup of acetabular fractures, the operation time was significantly longer in the group with the combined injury (198 ± 104 vs. 176 ± 81 min, p = 0.001). The grade of successful anatomic reduction of the acetabular fracture did not differ between the two groups. Conclusion: Patients with a pelvic injury have a concomitant abdominal trauma in about 20% of the cases. The clinical course is significantly prolonged in patients with a combined injury, with increased rates of morbidity and mortality. However, the quality of the reduction in the subgroup of acetabular fractures is not influenced by a concomitant abdominal injury.
