Bone fractures

replacing bone and mimicking their structure for, various applications. When looking at biological materials, to determine their effectiveness as a scaffold or sufficient structure for various other uses, often they are tested for their resistance to fracture. This is referred to as fracture propagation. Bamboo Bamboo is well known for its sufficient mechanical properties, and great flexibility. It also has great fracture toughness. Bamboo is considered to be a bio composite, meaning it…

As sports keep growing on the degree of popularity, bone fractures happen with an increasing frequency; there are six of the most major and the most common types of fractures. The first type of the six majors is called a Simple or a Closed Fracture. As defined by Robert, a Simple Fracture is, “a break in the bone that may be complete or incomplete, but it doesn’t pierce the skin” (Robert 307). This type of fracture on the average side, since it depends on the type of accident in a sport for a…

as well. This assists with its strong fracture toughness. Unfortunately wood is easily cracked in the parallel region, but not the perpendicular…

Comminuted fractures are commonly caused by a high impact trauma or an already existing disease like osteoporosis. A high impact trauma, like a car accident, can cause a crushing force on a bone which results in the bone breaking into many pieces in a single area. On the other hand, a buckle fracture is caused by a high impact force straight from top to bottom of a bone. It can also be caused by a constant impact on a bone over time that causes it to bend or compress…

Canadians sustain a bone fracture every year. The majority of these fractures heal well; however, about 5 to 10% of fractures develop delayed or incomplete healing requiring additional medical intervention. While we understand some of the mechanisms controlling bone healing, an improved and in-depth understanding of the precise molecular as well as cellular mechanisms involved in correct bone formation during fracture healing is of great importance. The processes that occur during bone healing…

Types of Bone Fractures  Avulsion • A muscle or ligament pulls on the bone, fracturing it  Comminuted • Bone is shattered into many pieces Compression • Generally occurs in the spongy bone of the spine, for example a portion of the vertebra in the spine may collapse due to osteoporosis Fracture Dislocation • A joint becomes dislocated, and one of the bones of the joint has a fracture Bone Fractures Cont.  Greenstick Fracture • Bone partly breaks on one side, but not…

A hip fracture occurs when the UQ (upper quadrant) of a femur bone endures a break. To cause a fracture, one must fall or have a direct blow to the side of the hip. Many medical conditions such as osteoporosis, or cancer can affect the bone so much so that the bone weakens from loss of tissue making bones fragile enough to break even from standing and twisting. However, a hip dislocation occurs when the femur bone is forced out of the ball and socket joint. To dislocate a hip a fall from extreme…

Vertebral Compression Fracture (Lumbar) Overview- The vertebral compression fracture occurs when the vertebrae fracture or collapse, not necessarily a result of an evident trauma. Vertebral fractures, the vertebral body are typically compressed in a wedge shape (more evident in lateral projection to the x-ray) due to the normal kyphosis of the thoracic region, which focuses the forces before. In the lumbar vertebral fractures, the vertebral body is generally flattened, sometimes rotated…

with this disease. Osteoporosis is a bone disease that cutbacks bone mass. The bones become very brittle and frail and are unable to support your weight and usually fracture. The bones that are most likely to fracture are your hips, spine, wrist, shoulder and hip. The bones could become so weak that even if you were to cough or bend over they would fracture. As you grow your bones make new bone and get rid of old bone. When your body, at a young age, makes new bone faster than it breaks it down…

Osteoporosis is a skeletal disorder characterised by low bone density weakening of bony tissue. When this occurs bones are more prone to fractures Bone loss happens without any symptoms that’s why some individuals might not know that they have osteoporosis until the bones are so weak and fragile. Women are affected by osteoporosis than men because women have lower dense bone mass and an increased rate of low bone mass especially after menopause. Primary osteoporosis is the most common type of…
