Assessment of the correlation between rock brittleness and rock fracture toughness has been the subject of extensive research works in the recent years. Unfortunately, the brittleness measurement methods have not yet been standardized, and rock fracture toughness cannot be estimated satisfactorily by the proposed indices. In the present study, statistical analyses are performed on some data col...

PURPOSE To determine if specific coronoid fractures relate to specific overall traumatic elbow instability injury patterns and to depict any relationship on fracture maps and heat maps. METHODS We collected 110 computed tomography (CT) studies from patients with coronoid fractures. Fracture types and pattern of injury were characterized based on anteroposterior and lateral radiographs, 2- and...

OBJECTIVE Hearing impairment has been suggested to increase the risk of falls. However, most previous studies were conducted in an older population without classification of the fracture regions. This study aimed to delineate the risk of each fracture type in all age populations. METHODS The Korean National Health Insurance Service-National Sample Cohort was collected from 2002 to 2013. A tot...

Background: The fracture of the mandible is the second most common facial bone injury.  When this injury occurs, it could be serious with complications that may even result in death. Objective: To evaluate the current trends in mandibular fracture (MF) in southern Iran. Methods: In a cross-sectional study, several parameters including age, sex, cause of fracture, anatomical site of fracture, pr...

displaced fracture of the acromion without associated shoulder injury occurs rarely. a 31-year-old gentleman presented with an isolated acromion fracture resulting from a direct trauma to the top of his left shoulder. open reduction and internal fixation using multiple pins was performed and the fracture was closed without complications. the patient achieved excellent shoulder function and rank...

at neck region called as Trans cervical neck fracture. Third bone shows fracture that happens at intertrochanteric line of femur bone known as Intertrochanteric fracture. The fourth bone shows the fracture that happens at sub trochanteric region named as subtrochanteric fracture, Fracture that happens at greater trochanter region shown in fifth bone is known as fracture at greater trochanter, i...

An investigation into the mixed mode fracture of steel fiber reinforced concrete (SFRC)beams with one percent volume fraction of steel fiber is presented. A series of notched beams withdifferent notch depths and locations are tested under three-point bending. The test results for apparentfracture toughness, crack trajectories, and fracture energy are presented. The crack paths for SFRCand plain...
