Flat bones consist of spongy bone sandwiched between compact bone. is this statement true or false?2/19/2024 ![]() ![]() Other factors such as lower bone density and osteoporosis increase the incidence of fracture. Fractures are often associated with penetration injuries on the battlefield. Fractures commonly happen because of falls, car accidents or sports injuries. A fracture is accompanied by various degrees of injury to the surrounding soft tissues, including blood supply, and in most instances results in compromised function of the locomotor system. This study provides an overview of the processes of fracture healing and discusses the current therapeutic strategies that have been claimed to be effective in accelerating fracture healing.Ī bone fracture or an osteotomy is a complete or incomplete break in the anatomic continuity of bone, which leads to mechanical instability of the bone. The main goals of this work are to present different treatment modalities of the fractured bones and to explain how fractures normally heal and what factors interfere with fracture healing. To select an appropriate treatment strategy in achieving a successful and secure healing, more information concerning injuries of bones, their healing process and knowledge of the factors involved are required. ![]() Bone tissue engineering is a newer option than the traditional grafts and may overcome many limitations of the bone graft. Nevertheless, these organic and synthetic materials and therapeutic agents have some significant limitations, and there are still no well‐approved treatment modalities to meet all the expected requirements. Different types of growth factors, stem cells, natural grafts (autografts, allografts or xenografts) and biologic‐ and synthetic‐based tissue‐engineered scaffolds are some of the examples. Different therapeutic modalities have been developed to enhance the healing response and fill the bone defects. Repair of large bone defects resulting from trauma, tumours, osteitis, delayed unions, non‐unions, osteotomies, arthrodesis and multifragmentary fractures is a current challenge of surgeons and investigators. ![]() Fracture healing is a complex physiological process, which involves a well‐orchestrated series of biological events. ![]()
