Bone fractures are among the common disorders worldwide. The healing process of a fracture is a relatively long period. Furthermore, a significant portion of fractures become nonunions or delayed that increase the long healing process of fractures even more. These characteristics have provoked the researchers to develop new techniques for reducing the healing process of fresh bone fracture as w...

BACKGROUND Individuals with osteoporosis are predisposed to hip fracture during trips, stumbles or falls, but half of all hip fractures occur in those without generalised osteoporosis. By analysing ordinary clinical CT scans using a novel cortical thickness mapping technique, we discovered patches of markedly thinner bone at fracture-prone regions in the femurs of women with acute hip fracture ...

BACKGROUND Currently it is uncertain how to define osteoporosis and who to treat after a hip fracture. There is little to support the universal treatment of all such patients but how to select those most in need of treatment is not clear. In this study we have compared cortical and trabecular bone status between patients with spinal fractures and those with hip fracture with or without spinal f...

by Travis L. Turnbull Human cortical bone, like many engineering materials, is subject to damage and fracture, especially resulting from cyclic loading conditions routinely experienced by the load-bearing long bones. Unlike other materials, bone possesses a unique ability to repair damage and prevent or reduce fracture risk. However, in cases such as athletes and military recruits, the rate and...

This dissertation investigates bone fracture fixation. In the proposed method, bone fractures are stabilized using multiple bioresorbable metallic or polymer darts/nails that are inserted into bone at high velocity and which are subsequently incorporated/absorbed by the body so that removal is unnecessary. This dissertation will introduce the proposed method in detail and discuss its advantages...

The paper presents an analysis of cases of treatment of humeral shaft fracture non-union following operative treatment. Non-union was treated by locked intramedullary nailing in all patients. Bone destruction at the fracture site is an indication for using bone grafts. In our opinion autologous bone marrow injection to the fracture site is an effective method of bone union stimulation, and this...

The sesamoid bone ligament complex of foot contains two sesamoid bones one medial tibial sesamoid and other lateral fibular sesamoid bone, both embedded in the plantar ligament beneath first metatarsal head. The incidence of medial tibial sesamoid bone fracture is rare. Clinically they are often misdiagnosed as soft tissue injuries and often missed. We present a case of fracture medial tibial s...

Anti-fracture agents typically prevent fractures by augmenting bone mass and enhancing skeletal integrity. These agents exert their effects by means of anti-catabolic or anabolic actions. Because fracture healing involves bone formation as well as bone resorption, it is reasonable to hypothesize that agents that affect these activities may also modulate skeletal repair. Bisphosphonates, agents ...

The risk of bone fracture increases with age because of a variety of factors that include, among others, decreasing bone quantity and quality. Despite recent advances, the roles of bone microstructure and trace mineralization in the fracture process are not well understood. In this study, we utilize a combination of in-situ fracture toughness testing, digital strain mapping, and X-ray photoelec...

Following bone fracture, the repair process starts with an inflammatory reaction at the fracture site. Fracture healing is disturbed when the initial inflammation is increased or prolonged, whereby, a balanced inflammatory response is anticipated to be crucial for fracture healing, because it may induce down-stream responses leading to tissue repair. However, the impact of the immune response o...
