Abstract:

Analysis of the stability of slopes in fractured rock masses is not trivial and is fraught with uncertainty and risk. A DFN-DEC model (Discrete Fracture Network-Distinct Element Code) based on the MATLAB platform is developed to evaluate the stability of rock slopes with random fractures. Then, the influences of mean values of geometric characteristics (i.e., the trace length T, the dip D, and the spacing S) for both the horizontal (denoted with 1) and inclined (denoted with 2) fractures on the mean slope stability are investigated. The results indicate that the proposed DFN-DEC model based on

Abstract:

Purpose: Fracture stability is important in choosing the optimal treatment for pediatric femoral fractures, although there is no consensus for characterizing a fracture as “stable” or “unstable.” The authors sought to measure interobserver and intraobserver reliability in classifying femoral fracture stability and examined the relationship between fracture ratio and perceived fracture stability and morphology. Methods: Fracture ratios were calculated from anteroposterior and lateral radiographs from 65 children aged 5 to 12 years, who were treated for femoral shaft fractures at a level 1 pedia

Abstract:

Summary The theory of linear-elastic fracture mechanics is used to develop an analytical solution for a wellbore in an isotropic elastic medium when drilled inclined to a general state of 3D far-field stress, and attached to which are an arbitrary number of N straight and axially aligned fractures. Axial alignment refers to the special case where the borehole axis is the existing common interface of all planes defined by the fracture faces. The solution uses a familiar load decomposition and coordinate-transform scheme. Within the fracture-mechanics context of the analysis, this scheme transla

Abstract:

Summary: The stability of intertrochanteric fractures depends upon multiple factors including the fracture displacement, location and pattern, the type of fixation used for stabilization, and the loading that the fracture undergoes postfixation. Traditional classification systems are of limited utility because they typically stratify intertrochanteric fractures as stable or unstable based purely on the fracture pattern without consideration of the stability after fixation. Biomechanical studies evaluating the stability of various fixation constructs should include physiologic loading, includin

The fractures in brown coal influence fluid flow and deformation in these materials. These fractures display highly heterogeneous characteristics in the distributions of their apertures, separations and orientations. While discrete fracture models have previously been used to analyse the effects of fractures, such models are not feasible for the scales encountered in many brown-coal mines. Instead, here a continuum permeability model is used to capture the effects of the fracture heterogeneity on fractured coal.

This approach potentially results in interpatient deviations due to different bone morphologies and consequently variations in fracture stability.

Abstract:

The development of shear-slip cracks and motion trend of fracture water were presented for discussing the shear-slip behavior and analyzing the stability of fractured rock slope under hydraulic action. Seepage behavior of epigenetic cracks and the positions of slip or collapse were also investigated by monitoring pore water pressure using DEM. The analysis method of discrete element simulation for fractured rock slope was proposed. The results of numerical simulation indicated that interpenetrating fractures are more likely to be slip planes.

Abstract:

Femoral neck fractures have significant orthopedic difficulty, particularly in younger patients with high-energy trauma. The femoral neck system improves rotational stability, allows for controlled dynamic compression, and is less invasive than cannulated cancellous screws. However, steep learning curves, more significant starting expenditures, and more long-term data still need to be addressed. Emerging technologies, such as robotic-assisted surgeries and personalized implants created with artificial intelligence and 3D printing, can transform fracture therapy by boosting accuracy, lowering c

Abstract Introduction Surgical treatment of bi-condylar tibial plateau fractures is still challenging due to the complexity of the fracture and the difficult surgical approach. Coronal fracture lines are associated with a high risk of fixation failure. However, previous biomechanical studies and fracture classifications have disregarded coronal fracture lines.

Abstract:

The naturally fractured reservoirs are one of the most challenging due to the tectonic movements that are caused to increase the permeability and conductivity of the fractures. The instability of the permeability and conductivity effects on the fluid flow path causes problems during the transfer of the fluids from the matrix to the fractures and fluid losses during production. In addition, these complications made it difficult for engineers to estimate fluid flow during production. The fracture properties’ study is important to model the fluid flow paths such as the fracture porosity, permeabi

Tumor-induced osteomalacia (TIO) is a rare skeletal disease caused by hypersecretion of fibroblast growth factor 23 (FGF-23) from neoplasms of mesenchymal origin; patients with TIO present with insufficiency fractures, progressive bone pain, and delayed fracture unions. Herein, we report the case of a 48-year-old man with an insufficiency fracture in his left femoral neck associated with TIO. The causative tumor located in the patient’s maxillary sinus had been resected; however, complete resection was impossible due to the location of the tumor. Therefore, the patient’s osteomalacia persisted

SummaryThe influence of fracture stability on the healing of intra-articular fractures of canine medial femoral condyles repaired with lag screws was evaluated radiographically and at necropsy. In 14 dogs, one condylar fracture was repaired with stable interfragmentary compression using two 4.0 mm cancellous lag screws. In the contralateral stifle, the condylar fracture was apposed with a single 4.0 mm cancellous lag screw so that the bone fragments were unstable and had interfragmentary motion. In a control group (n = 4), an arthrotomy was performed and a lag screw inserted without creating a

ABSTRACT Background Malleolar fractures of ankle are usually complex injuries, as they are associated with significant ligament and soft tissue injury—injury to syndesmosis and injury to medial and lateral collateral ligaments. The open reduction and internal fixation is not feasible until recovery of significant soft tissue injury and subsidence of edema. Malleolar fractures are articular fractures and have associated subluxation and dislocation of talus. The aims of treatment are to restore normal anatomy and provide sufficient stability for early movements. Malleolar fractures more often re

Abstract:

Intertrochanteric femoral fracture with peritrochanteric fracture is a common osteoporotic fracture that is difficult to treat and has a high complication rate. Intertrochanteric femoral fracture is a fracture between the base of the femoral neck and the level of the lesser trochanter. Intertrochanteric fractures can be divided into internal and external types, with the external type of fracture being more common. Peri-rotor fractures, on the other hand, are fractures in the area around the femur’s rotor, including fractures of the greater and lesser trochanter and intertrochanteric line
