Biomechanical comparison of Schanz screws placement modes-how can stability by external fixation be raised?
Abstract: AbstractBackground: At present, external fixators are being used widely in open fractures of the long bones and also accepted as a temporary skeletal stabilization even in closed fractures. Therefore, it is essential to increase the stability which is provided by those devices for good outcomes. We hypothesized prior to the study that the greater is the distance between the Schanz screws inserted in each fracture fragment, the higher is the …

Fracture Analysis of Laminated composite plates using Extended Finite Element Method: A Review
Abstract: Laminated composite plates are used in aerospace, automotive, and marine industries. They feature great durability against fatigue, a high strength-to-weight ratio, and mechanical attributes that may be altered. However, they are prone to fracture and delamination under complex loading, requiring accurate fracture analysis for structural integrity. Traditional finite element methods (FEM) need extensive mesh refinement for modelling crack propagation which increases the computational costs. The Extended Finite Element Method (XFEM) …

Wave plate; what is the angle of its central curved segment which provides biomechanically optimal stability for femoral shaft fracture?:A 3-D Finite Analysis
Abstract: Even though intramedullary nailing of femoral shaft fracture is the standard surgical treatment as it is in tibial fracture, plate fixation might be a choice when the fracture involves open growth plate, patients are of shorter stature or have narrow canals. In these cases, fixation techniques with plate and screws, for example, percutaneous procedures involving wave plate, are useful thanks to minimal invasion and preservation of biological environment surrounding the …

Comparison of Lateral and Medial Plate Fixations of Talar Neck Fracture: A 3D-Finite Element Analysis
Abstract: Background: Talar neck fractures are rare, but challenging injuries, because the bone has unique anatomy, and its blood supply makes it difficult to stabilize the fracture and is likely to cause posttraumatic or postoperative complications. Thanks to development of appropriately sized plates, outcomes of plate fixation of talar neck fractures have been improved compared with screw fixation. Although some studies have demonstrated no difference between screw only fixation and screw-plate …

Can Screw-only fixations of ACPHT acetabular fractures enhance stability as the standard buttress plate fixation provides?
Abstract: Background: Of acetabular fractures, anterior column posterior hemi-transverse(ACPHT) fractures commonly occur after a fall onto the hip in elderly population. When displaced in these fractures, open reduction and internal fixation using plate and screws is usually required to achieve good functional outcomes. The open procedures, however, involve high complication rates due to surgical invasion; therefore, percutaneous techniques by screw-only constructs have been advocated to minimize these complications. The purpose of …

Hydrothermal modification of carbon fiber fabrics by ZnO nanorods for mechanical strengthening of CFRP laminates
Abstract: Hexagonal ZnO nanorods were produced on plain woven carbon fiber using a two-step seed-assisted hydrothermal procedure. By varying the process parameters such as molar concentrations, number of seeding cycles, and growth duration at a controlled growth temperature of 90 °C, it is feasible to produce ZnO nanostructures with a range of morphologies, including nanowires, hexagonal nanorods, and nanoflowers. The developed morphologies were examined using field emission scanning electron microscopy and …

Productivity of Hydraulically Fractured Calcite Rich Shale Reservoirs Enhanced by Acid
Abstract: The current low oil prices have highlighted the need for enhancement to current production from shale formations. Prolonging the production life and increasing productivity of the fracture network in the shale plays can be a way to improve the economics. Many shale wells, drilled and completed based on current completion strategies, show sharp decline after initial flash production. One of the reasons behind this can be attributed to closure of …

Quantifying Damage Evolution in Fiber-reinforced Composites Using Fracture Mechanics
Abstract: By evaluating the evolution of damage, such as cracks or delamination, within the material over time or under various loading situations, damage evolution in fiber-reinforced composites can be characterized using fracture mechanics. Fracture mechanics offers a framework for understanding and projecting the behavior of materials that already have damage or flaws. Since they have a high strength-to-weight ratio and unique mechanical qualities, fiber-reinforced composites are essential in many branches of …
