Cancellous bone

Bone grafting is performed to restore bone that has been lost due to injury, trauma, or disease. Injury may cause haematoma and bleeding from adjacent structures to occur. Haematoma is clotting of blood that occur in any specific region such as around the broken bone ends. This event is localized. Two ends involved are proximal and distal bone end which is the medium for osteonal healing (ossification) to occur. Ossification is the process of bone formation that is usually beginning at particular

Epidemiology Colles fracture becomes more recurrent with increasing age and occurs more in women with osteoporosis. This is because osteoporosis is a progressive disease which in time drastically reduces bone density and ' micro-architectural deterioration of bone tissue '

many diseases caused by poor nutrition. One disease young children are at risk for is rickets. Rickets is caused by a vitamin D, calcium, and phosphorus deficiency. Rickets is the softening and weakening of the bones in children. Skeletal deformities and fractures can occur because the bones are so soft and weak. Rickets is seen during periods of rapid growth because during growth a great deal of vitamin D, phosphorus, and calcium are needed. “The predominant cause is a

that is used to inhibit osteoclastic bone resorption .it works by attaching to hydroxyapatite binding sites to impair the ability of the osteoclasts to produce the protons necessary for continued bone resorption. It also inhibit osteoclast activity by promoting osteoclast apoptosis. (pubmed ) Patient group who are mostly taking this medication are postmenopausal women. As women reaches their menopausal age, oestrogen starts to deplete which causes their bones to

Bone formation and bone break down is a very important maintenance of the human body. After tooth eruption teeth move and need new bone to form constantly. Due to the wear of enamel on the interproximal and occlusal surfaces teeth are constantly moving in the mouth. For that reason, Osteoclasts are activated and they begin to breakdown old bone. On the opposite side of the tooth osteoblasts lay down new bone. With age however bone begins to change. When a person is young they have healthy, dense

Osteoporosis is a progressive bone disease that is characterized by low bone mass along with continuous loss of bone tissue with increased fracture risk. The pathology is multi-factorial and there are several modifiable and non-modifiabale factors that contribute to the development of this disease. According to the World Health Organization, osteoporosis is defined as a systemic skeletal disease illustrated by a decrease in bone mass and bone tissue, causing a decrease in bone and a subsequent increase

phase "lacking cartilage development." Cartilage is hard and durable but is also a flexible tissue that makes up most of the bone structure during the early stages of development. Nonetheless, in achondroplasia there is no problem with developing cartilage, but instead the problem comes in converting it to bone, a development known as ossification, predominantly in the longer bones of the arms, such as the humerus, ulna and radius, and legs, which include the femur, tibia and fibula. Achondroplasia is

meaning porous bone from the Greek language, is bone disease that gradually and steadily wears down bone tissue and its living cells. This wearing down will eventually cause the cells of bone tissue to degrade and die, leaving their “scaffolding” to be the only things only bone together. Without living cells to take up a home in this scaffolding, minor injuries such as falls, bumping into objects, and pressure that would normally be completely and would not pose any threat to bone tissue suddenly

disease is very painful and quite common in people when they grow old, so therefore it is important to know every aspect from beginning to end. In the joints there are bones, and around the bones there is cartilage and synovial fluid. Cartilage is the a smooth covering that helps the bone move without rubbing bone to bone or bone to joint (2008, schueler). The primary factor here is cartilage. When there is no cartilage it causes intense
