Bones are the principal structural components of a skeleton; they play unique roles in the body providing its shape maintenance, protection of internal organs and transmission of forces. Ultimately, their structural integrity is vital for the quality of life. Unfortunately, bones can only sustain loads until a certain limit, beyond which they fail. Understanding a fracture behaviour of bone is ...

Delayed bone healing and non-union occur in approximately 10% of long bone fractures. Despite intense investigations and progress in understanding the processes governing bone healing, the specific pathophysiological characteristics of the local microenvironment leading to non-union remain obscure. The clinical findings and radiographic features remain the two important landmarks of diagnosing ...

conclusions saddle nose reconstruction with bone graft in multiple facial fracture patients is a predictable method if surgical accesses to the region are carefully designed, considering the accompanying fractures. results there were 11 patients treated using this method. the male-to-female ratio was 7:5. one miniscrew with the lag technique was the preferred method for the fixation of the dors...

BACKGROUND There are several factors that can affect the fatigue life of a bone plate, including the mechanical properties of the plate and the complexity of the fracture. The position of the screws can influence construct stiffness, plate strain and cyclic fatigue of the implants. Studies have not investigated these variables in implants utilized for long bone fracture fixation in dogs and cat...

background: the main purpose of this study was to determine the relationship between serum vitamin d and the status of bone mineral density in patients with low-energy hip and distal radius fracture. methods: this retrospective case-control study was performed between january 2013 and january 2014. participants aged 55 years or older were divided to case group including 85 patients with low-ene...

Introduction: The purpose of the present study was to evaluate the effect of prednisolone on the sensitivity of bone scanning to detect the simulated closed fracture in the rat tibia.  Methods: A total number of forty eight adult, male NMRI rats randomly assigned into two parts, one part for 4 and other for 8 weeks experiments. Each part has been divided into four groups, one group not receivi...

Bone formation during fracture repair inevitably initiates within or around extravascular deposits of a fibrin-rich matrix. In addition to a central role in hemostasis, fibrin is thought to enhance bone repair by supporting inflammatory and mesenchymal progenitor egress into the zone of injury. However, given that a failure of efficient fibrin clearance can impede normal wound repair, the preci...

abstract   background: the tibial diaphyseal fractures are the most common type of long bone fractures encountered by most orthopedic surgeons. in accordance with descriptive indices of tibia fractures on the basis of their location in the bone, distal tibia fractures have the second incidence of all tibia fractures after the middle tibia fractures. the purpose of the study was to assess the co...

case presentation here, we report the case of a 35-year-old man complaining of bilateral incomplete eye closure, two weeks after a closed head injury caused by a motor vehicle accident. introduction although bilateral facial nerve palsy is a rare condition, its etiology is more detectable than the unilateral type. a temporal bone fracture is one cause of bilateral facial nerve palsy, contributi...
