Objective: To investigate the effectiveness of the plate screw internal fixation technique on the clinical outcomes of patients with traumatic fractures of long bones in the lower extremities. Methods: From January 2022 to December 2023, 70 patients with traumatic fractures of long bones in the lower extremities were admitted to the hospital and randomly divided into two groups: the control group and the observation group, each consisting of 35 cases. The control group underwent traditional closed interlocking intramedullary nailing, while the observation group received internal fixation with steel plates and screws. Relevant surgical indicators, treatment effectiveness, and postoperative complication rates were compared between the two groups. Results: The observation group exhibited significantly short surgical duration (80.65 ± 5.01 vs. 88.36 ± 5.26 minutes), fracture healing time (13.27 ± 0.32 vs. 15.52 ± 0.48 weeks), and hospitalization days (10.49 ± 1.13 vs. 16.57 ± 1.15 days) compared to the control group (P = 0.000). The effective treatment rate was significantly higher in the observation group (29/82.86%) than in the control group (21/60.00%), with a significant difference observed (χ2 = 4.480, P = 0.034). Additionally, the complication rate in the observation group (2/5.71%) was significantly lower than that in the control group (8/22.86%), with a correlated difference (χ2 = 4.200, P = 0.040). Conclusion: The plate screw internal fixation technique demonstrates significant clinical efficacy in treating traumatic fractures of long bones in the lower extremities. It improves the healing rate, reduces complications, and represents a safe and effective treatment strategy worthy of widespread use and application. 展开更多

Lower limb injures are frequently observed in passenger car traffic accidents.Previous studies of the injuries focus on long bone fractures by using either cadaver component tests or simulations of the long bone kinematics,which lack in-depth study on the fractures in stress analysis.This paper aims to investigate lower limb impact biomechanics in real-world car to pedestrian accidents and to predict fractures of long bones in term of stress parameter for femur,tibia,and fibula.For the above purposes,a 3D finite element(FE) model of human body lower limb(HBM-LL) is developed based on human anatomy.The model consists of the pelvis,femur,tibia,fibula,patella,foot bones,primary tendons,knee joint capsule,meniscus,and ligaments.The FE model is validated by comparing the results from a lateral impact between simulations and tests with cadaver lower limb specimens.Two real-world accidents are selected from an in-depth accident database with detailed information about the accident scene,car impact speed,damage to the car,and pedestrian injuries.Multi-body system(MBS) models are used to reconstruct the kinematics of the pedestrians in the two accidents and the impact conditions are calculated for initial impact velocity and orientations of the car and pedestrian during the collision.The FE model is used to perform injury reconstructions and predict the fractures by using physical parameters,such as von Mises stress of long bones.The calculated failure level of the long bones is correlated with the injury outcomes observed from the two accident cases.The reconstruction result shows that the HBM-LL FE model has acceptable biofidelity and can be applied to predict the risk of long bone fractures.This study provides an efficient methodology to investigate the long bone fracture suffered from vehicle traffic collisions. 展开更多

Background: Rapid urbanization and increasing fleet in low-income countries are the basis of the higher rate of trauma and fractures. In a post conflict environment, the abnormal movement of firearms and poverty from them may change the configuration’s epidemiological, anatomical and clinical fractures of the limbs bones as well as their care. Goal: To make an inventory on the fractures of the limb bones in Bukavu town, a town in post armed conflict. Method: This work is transversal, retrospective and descriptive on 500 fractures of the limbs bones recorded on a period of 3 months from 1st June to 31st August 2013. Twenty investigators went around different places of Bukavu town to interview and complete a research protocol ad hoc. In total, we recorded 500 subjects with 570 fractures of the limb bones. Results: The average age is 29.4 years old and 37% are male fractured. The main circumstances of occurrence of the fracture of the limbs bones are the falls (31.7%), firearms (22.2%) followed closely by road traffic accidents (21.9%). Students (38.6%) and the unemployed (29.4%) are most victims’ fractures of limb bones. The forearm bones (31.7%) and leg bones (27.2%) are most concerned, 52.2% fractured turned to modern medicine against 41.8% for traditional medicine. Conclusion: The fractures of the limbs bones in Bukavu mainly concern young male subjects. They occur with the waning of a fall and preferentially affect the bones of the forearm. Good governance would reduce the incidence of fractures of the limbs bones and their assessment. 展开更多

The locking compression plates (LCP) are efficient tools in open reduction and internal fixation (ORIF), especially in osteoporotic bones. Two important factors of screw density and screw position can affect the functionality of the bone plate. Several studies have assessed the influence of the screw configurations on the bone-plate stiffness, but the effects of screw positions on the interfragmentary strain, εIF of LCP construct have not been investigated yet. In this study, finite element method was used to investigate the influence of screws number and position on the interfragmentary strain of LCP-femur system for a mid-shaft fracture. Results of this study showed that by insertion of screws closer to the fracture site, εIF decreases by 2nd degree polynomial function versus screw position, but by adding the screws from the ends of the plate, or by moving and placing the screws towards the fracture site, the reduction of εIF will be linear. Results of this study were compared and are in agreement with some studies in the literature, even though their scope was mostly stability of the bone-implant system, whereas our scope was focused on the interfragmentary strain. 展开更多

Background: Bone fracture frequencies and survival rates are essential parameters in skeleton evolution, but information on the functional consequences of naturally healed fractures is scarce. No leg bone fracture healing in the wild has been reported so far from long-legged Charadriiformes(waders), which depend on bipedal locomotion for feeding.Methods: We documented a healed but malaligned tarsometatarsus fracture in a wild Willet(Tringa [Catoptrophorus]semipalmata), and a malaligned tibiotarsus fracture in a Curlew(Numenius arquata) skeleton from a museum collection. Functional consequences of the malalignments were evaluated by kinematic analyses of videos(Willet) and in silico 3D modeling(Curlew).Results: The Willet's left tarsometatarsus exhibited an angular malalignment of 70°, resulting in a limping gait that was less pronounced at high than at low walking speed. The bird seemed unable to club the toes of the left foot together, apparently a secondary effect of the deformity. The Curlew's tibiotarsus showed an angular and an axial malalignment, causing the foot to rotate outwards when the intertarsal joint was flexed. Despite the severe effects of their injuries, the birds had survived at least long enough for the fractures to heal completely.Conclusions: Somewhat unexpectedly, leg fractures are not necessarily fatal in long-legged waders, even if deformities occur in the healing process. Bipedal locomotion on vegetated grounds must have been impeded due to the bone malalignments in both analyzed cases. The birds probably alleviated the impact of their handicaps by shifting a larger proportion of their activities to vegetation-free habitats. 展开更多

Background: Although the original clinical description of fat embolism syndrome (FES) dates from 1873, the condition remains a diagnostic challenge for modern clinicians. The syndrome is described as a serious consequence of fat emboli producing a distinct pattern of clinical symptoms and signs. It is mainly associated with fractures of the long-bones and the pelvis. The present paper describes the case of a trauma patient with bilateral tibial fractures that present the syndrome and highlights the importance of early identification and aggressive treatment of FES which is obligatory for the patient’s survival. Case Description: A 32 year-old man reached the hospital as a trauma call after a road traffic accident. Clinical examination was unremarkable with the only finding that the patient was unable to straight leg raise and weight bear. Both shins were painful and swollen at their middle third, while the left one was in varus and posterior displacement. Neurovascular status of both lower extremities was normal. Plain radiographic control (X-Rays) revealed an oblique right tibial fracture of the mid-shaft with a distal third fibular fracture and a comminuted fracture of the left tibia with a fracture of the fibula at the same level. The legs were immobilised on a splint and the decision was to treat the patient surgically. Within a few post admission hours the haemoglobin dropped by 2.9 mg/dL, however a source of active bleeding could not be allocated. The abdomen was soft and not tender in palpation and the central nervous system did not present any abnormalities. The following day the haemoglobin dropped but the new ultrasonography control did not reveal any free abdominal fluid. Both lower limbs were not compromised. The second post-injury day the patient went to theatre and the right tibia was stabilised with an antegrade nail (T2-Stryker) while the left one with an external fixation. During the reaming process the haemoglobin dropped to 7.1 gr/dL, so he was transfused with 3 blood units. Immediately after extubation, the patient desaturated on air and ABG values forced the anaesthetists to intubate him in recovery and place him in mechanical ventilation with high levels of positive end expiratory pressure (PEEP). Symptoms subsided rapidly and he was transferred to the IMU. Clinical image and CT scan were in favour of fat embolism syndrome. On the fifth post-operative day the patient was transferred back to ward and a week later he was discharged being completely free of symptoms. Clinical Relevance: Fat embolism syndrome is typically presented with the following triad: a) respiratory changes;b) neurologic abnormalities;c) petechial rash. These three constitute the major criteria described by Gurd and are pathognomonic for the condition. The patient—described in the present case report—developed progressively all those symptoms within the expected period of time. The FES is a well-known pathological condition that is well described in literature and should be familiar to those clinicians that manage trauma patients. Diagnosing the condition can be highly demanding since there are no laboratory investigations or radiographic imaging techniques specific for FES. Suspicion and diagnosis can be mainly placed based on the criteria described by Gurd, in 1970. 展开更多

Falls represent a significant contribution to the morbidity and mortality of the elderly population. Because vitamin D is important in bone physiology, the use of vitamin D to restore deficient bone and ameliorate the effects of bone fractures due to falls has become a common practice in recent years. Following introduction of widespread use, reports began to emerge that vitamin D not only aided in repair of fall-induced bone fractures, but that it also reduced the occurrence of falls. Vitamin D now has become a routine intervention as a fall-prevention measure. Early analyses found evidence of prevention efficacy (reduced falls), but recent analyses are more equivocal. We retrospectively examined the records of 350 patients in a long-term care facility in which vitamin D administration and the number of falls were recorded as part of a comprehensive database of care. We found a dramatic rise in vitamin D use over the period covered (2006 – 2011) and a corresponding dramatic decrease in the number of falls. However, the number of falls continued to decline after 2008, despite a plateau in number of patients on vitamin D, particularly females. It appears that other factors contribute to the overall decline. 展开更多

Using ultrasonic guided waves to assess long bone fractures and fracture healing has become a promising diagnostic issue. But the multimode overlap of the guided waves challenges the quantitative evaluation and clinical application. In the preformed study, in order to simplify the signal interpretation, the low-frequency sinusoidial signals were used to only excite SO and A0 modes in fractured long bones. The amplitudes of SO and A0 modes were numerically analyzed with variation in crack width and fracture angle. Numerical simulation, based on the two-dimension finite-difference time-domain (2D-FDTD) reveals that both SO and A0 amplitudes decrease with the fracture widening. However, the increase in fracture angle gradually enhances the A0 amplitude, while with respect to the SO mode, its amplitude shows a non-monotonic trend to the variation in fracture angle with a turning point around 45°. The amplitude ratio between S0 and A0 can reflect the variations in crack width and fracture angles. The simulation illustrates that ultrasonic guided SO and A0 modes are sensitive to the degree of both vertical and oblique fractures in the long cortical bone. These findings may be helpful for fractures diagnosis and healing evaluation of the long bone. 展开更多
