In this work, the FEM is used to model a mandibular fracture (using an inhomogeneous and orthotropic jaw model) simulating the effect of different bite tasks/forces on the stability of the fixated fracture. Specifically, bilateral and unilateral clenches (using muscle data) were studied using a low-profile 3D 4 × 2 hole mini-plate deployed for fracture fixation. Here, the mandible bone was treated as orthotropic and spatially inhomogeneous. Although the results of stress and displacement analyses, for this fixation hardware, indicate sufficient fixation under normal biting conditions, the results show that the unilateral and ipsilateral bites develop, in general, the highest stresses or displacements. Such results can guide post-surgery recommendation on bite behavior.展开更多

Many authors recommended immediate debridement, but the optimal timing of internal fixation and the use of antibiotic have not been determined. The purpose of this paper is to present and discuss our experience. Material and methods: In January 2007, a treatment protocol was put in place for the evaluation and management of fractured extremities resulting from civilian gunshot wounds. Sixty-three patients with 64 fractures had been managed by this protocol for gunshot fractures between January 2005 and January 2012. There were 56 male and seven female. Their mean age was 33.1 years (range: 17 - 61 years). Thirteen patients (20.6%) were able to provide a description of the weapon. Only 15 patients had entry and exit wounds. The mean follow-up period was 27 (range, 20 - 58) months. The main factors assessed were the surgical site infection, the fracture union and the functional status. Results: Out of the 63 patients, 14 patients developed a wound infection (five superficial and seven deep infections). Wound infection was significantly associated with associated injuries (p = 0.0388), fractures sites requiring fixation (p = 0.024), the fracture pattern (p = 0.0412), operative modalities (p = 0.0400). There were nine cases (14.1%) of fracture non-union. The mean time to union was 15 weeks (range: 5 - 32 weeks). Five patients developed chronics osteomyelitis. The average SMFA score for all of the patients was 23.8 (range: 0 - 56.3). The mean dysfunctional and bother indexes were 18.3 (range: 0 - 52.7) and 22.6 (range: 0 - 66.1), respectively. The SMFA total score and dysfunction index had a significant correlation based on presence or absence of associated injuries (p < 0.0001). But bother index did not show the same correlation (p = 0.452). The average length of hospital stay was 11.3 days (range: 3 - 64). Conclusion: In civilian’s gunshot induced fractures, internal fixation can be made according to standard protocol, with acceptable result.展开更多

Material and methods: In January 2007, a treatment protocol was put in place for the evaluation and management of fractured extremities resulting from civilian gunshot wounds. Sixty-three patients with 64 fractures had been managed by this protocol for gunshot fractures between January 2005 and January 2012. There were 56 male and seven female. Their mean age was 33.1 years (range: 17 - 61 years). Thirteen patients (20.6%) were able to provide a description of the weapon. Only 15 patients had entry and exit wounds. The mean follow-up period was 27 (range, 20 - 58) months. The main factors assessed were the surgical site infection, the fracture union and the functional status. Results: Out of the 63 patients, 14 patients developed a wound infection (five superficial and seven deep infections). Wound infection was significantly associated with associated injuries (p = 0.0388), fractures sites requiring fixation (p = 0.024), the fracture pattern (p = 0.0412), operative modalities (p = 0.0400). There were nine cases (14.1%) of fracture non-union. The mean time to union was 15 weeks (range: 5 - 32 weeks). Five patients developed chronics osteomyelitis. The average SMFA score for all of the patients was 23.8 (range: 0 - 56.3). The mean dysfunctional and bother indexes were 18.3 (range: 0 - 52.7) and 22.6 (range: 0 - 66.1), respectively. The SMFA total score and dysfunction index had a significant correlation based on presence or absence of associated injuries (p < 0.0001). But bother index did not show the same correlation (p = 0.452). The average length of hospital stay was 11.3 days (range: 3 - 64). Conclusion: In civilian’s gunshot induced fractures, internal fixation can be made according to standard protocol, with acceptable result.
文摘<strong>Objective: </strong>To explore the therapeutic effect of autologous blood reinfusion combined with controlled hypotension in surgical spinal fixation during the outbreak of COVID-19. <strong>Methods: </strong>30 patients with spinal internal fixation autologous blood transfusion combined with controlled hypotension were selected as the subjects during the epidemic period from December 2019 to June 2020 in our hospital and during the operation, on the basis of routine blood pressure reduction, the American Haemonetice Corporation autologous blood continuous reinfusion system was used to infuse the blood recovered during the operation to the patient through filtration and other procedures. <strong>Results:</strong> 30 patients had no complications such as fever and hemolysis;And after the operation, the tube was dialed according to the drainage volume, the cervical thoracic and lumbar brace was customized, and the patient walked on the ground for one week;After no abnormalities, the patient was discharged. Intraoperative comparison of white blood cells (WBC), red blood cells (RBC), red blood cell pressure (HCT), hemoglobin (HGB), and coagulation time (PT) of patients with autologous blood before and after transfusion showed statistically significant differences before and after surgery (P < 0.001). <strong>Conclusion:</strong> During the new coronavirus pneumonia epidemic, the internal fixation of spinal surgery used a recovery machine to collect intraoperative blood for reinfusion. Intraoperative antihypertensive drugs were used to control blood pressure within a certain safe range. The postoperative clinical observation effect was significant and safe;especially at present the clinical significance during the epidemic was significant.

文摘BACKGROUND With the modernization of society and transportation in the last decades in China,the incidence of high-energy trauma increased sharply in China,including that of acetabular fractures.AIM To establish different finite element models for acetabular posterior column fractures involving the quadrilateral area of the acetabulum.METHODS The three-dimensional models of the normal and fractured pelvis and the five internal fixations were established using the computed tomography data of the pelvis of a living volunteer.After the vertebral body model was inserted in the way of origin matching and all cancellous bones were copied using the duplicated cancellous bone model as the subtractive entity,the Boolean operation was performed on the pelvis model to obtain the model of the complete pelvis cortical and cancellous bones.RESULTS In the standing position,the maximum stress was 46.21 MPa.In the sitting position,the sacrum bore the simulated gravity load at the upper end.When comparing the five fixations,there were no significant differences in the stress mean values among groups(sitting:P=0.9794;standing:P=0.9741).In terms of displacement,the average displacement of the internal iliac plate group was smaller than that of the spring plate group(P=0.002),and no differences were observed between the other pairs of groups(all P>0.05).In the standing position,there were no significant differences in the mean value of displacement among the groups(P=0.2985).It can be seen from the stress nephogram of the internal fixations in different positions that the stress of the internal fixation was mainly concentrated in the fracture segment.CONCLUSION There were no significant differences among the fixations for acetabular posterior column fractures involving the quadrilateral area of the acetabulum.
