Michael Orr Professor Shuler Brittle Bone Disease September 22, 2014 Brittle Bone Disease Have you ever experienced an accident that resulted in a broken bone? Maybe you fell roller skating or were in an automobile accident. If you answered yes, then you know how painful it can be. Breaking a bone is not only painful, but can also be troublesome and life changing. Breaking a bone can cause one to have restricted range of motion and movement. Each bone in the skeletal system serves a specific…

Metacarpal Fracture A metacarpal fracture is a break (fracture) of a bone in the hand. Metacarpals are the bones that extend from the knuckles to the wrist. There are five metacarpal bones that connect your fingers and your thumb to your wrist. Some hand fractures have bone pieces that are close together and stable (simple). These fractures may be treated with only a splint or cast. Hand fractures that have many pieces of broken bone (comminuted), unstable bone pieces (displaced), or bone that…

Osteogenesis Imperfecta Osteogenesis imperfecta, also known as “brittle bone disease”, is a genetic disorder characterized by fragile bones that break easily. Osteogenesis imperfecta is caused by a lack of collagen in the bones that affect the body’s ability to make strong bones. Collagen is the major protein of the body’s connective tissue. In dominant Osteogenesis imperfecta, a person has either a lack of type 1 collagen or a poor quality of type 1 collagen, caused by a mutation in one of the…

Osteogenesis imperfecta (OI) is a genetic disorder characterized by bones that break easily, often from little or no apparent cause. It is also known as brittle bone disease. OI can also cause many other problems such as weak muscles, brittle teeth, and hearing loss. About 20,000 to 50,000 people in the United States have OI. In this paper, I will cover the topics of etiology, pathophysiology, signs and symptoms, treatment, and prevention (National Institute of Health). Etiology Osteogenesis…

step in the process is that a 3-D image of the outer surface of the femur is made. The bone was laser scanned at the physical anthropology computer lab using a special 3-D laser scanning machine. Resulting data was a highly accurate representation of the superficial topographic features of the bone the initial 3-D data set contained eighty thousand facets. The second step was generating a 3-D model of the femur. The model was made to be manipulated digitally. The 3-D digital data was transferred…

Fibrous dysplasia is a skeletal disorder in which bone forming cell fail to mature and produce too much fibrous or connective tissue. Fibrous dysplasia is a rare bone disorder in which scar tissue develops in place of normal bone. This can weaken the affected bone and cause it to fracture.Fibrous dysplasia is linked to a gene mutation that affects the cells that produce bone. The mutation occurs after conception, in the early stages of fetal development. Which means the mutation isn't inherited…

Have you seen that bony lump at the inside of your big toe joint? If you did, you are most likely to have a bunion. This enlargement is actually a misalignment of your big toe joint, which can have additional bone formation in some cases. Such misalignment makes your big toe to point outward going to your small toes. Bunion, or medically termed as hallux valgus, is a progressive condition that worsens over time. There is a less common bunion called bunionette or tailor's bunion, which is…

Osteoarthritis is a worldwide chronic condition that has impacted the lives on many people today, causing pain, deformity, and difficulty with daily physical tasks. This chronic condition is, “believed to have a genetic cause or predisposition, and is caused by wear and tear on a joint. The cartilage wears away and exposes the bone.” (Rosdahl and Kowalski, 2006, p.1235) This chronic condition generally targets individuals with obesity and it is most commonly found among women. The…

Bone Metastasis Bone metastasis is cancer that spreads to the bones from another part of the body. A person may have bone metastasis in one bone or in more than one bone. Cancer that spreads to the bones is different from cancer that starts in the bones (primary bone cancer). Bone metastasis is more common than primary bone cancer. The spine is the most common area for bone metastasis. Other common areas include the: • Hip bone (pelvis). • Ribs. • Skull. • Long bones of the arm or…

Some individuals may believe that they are only able to receive social security disability payments if they happen to be visibly disabled, such as a condition that causes you to be in a wheelchair or being legally blind, but that’s not the case. One such condition that is not readily apparent that can qualify you to receive social security disability is parathyroid gland disorders. What is Parathyroid Gland Disorders Parathyroid gland disorders is an endocrine disorder, and your endocrine…
