What is bone cements?


A callus (tyloma) is a thickening of the skin that occurs in response to excessive, repeated shear or friction forces, commonly due to constant rubbing of the skin. Calluses are similar to corns, but calluses occur when abnormal forces are exerted over a larger area. Certain deformities of the feet, such as crookedness of the toes, may predispose to the development of calluses. Calluses may cause pain, typically a burning sensation. Excessive weight bearing and certain types of shoes are often contributing factors.

Bone spurs

A bone spur is an outgrowth of bone that can occur along the edges of a bone. It is also called an osteophyte. Bone spurs are can form in any bone, but are most commonly found in joints, where two or more bones come together. They also occur where muscles, ligaments, or tendons attach to the bone.

Bone Markers

What are they Bone markers are blood and urine tests that detect products of bone remodeling to help determine if the rate of bone resorption and/or formation is abnormally increased, suggesting a potential bone disorder. The markers can be used to help determine a persons risk of bone fracture and to monitor drug therapy for patients receiving treatment for skeletal disorders, including osteoporosis. Bone is a living, growing tissue that turns over at a rate of about 10% a year. It is made up largely of type-I collagen, a protein network that gives the bone its tensile strength and framework, and calcium phosphate, a mineralized complex that hardens the skeletal framework. This combination of collagen and calcium gives bone its hardness, and yet bones are flexible enough to bear weight and to withstand stress. More than 99% of the body's calcium is contained in the bones and teeth. The remaining 1% is found in the blood. Throughout a persons lifetime, old bone is constantly being removed (resorption) and replaced with new bone (formation) to maintain a healthy bone structure. During bone resorption, cells called osteoclasts dissolve small amounts of bone, while enzymes dissolve the protein network. Bone formation is then initiated by cells called osteoblasts. They secrete a variety of compounds that help form a new protein network, which is then mineralized with calcium and phosphate to produce new bone. This on-going remodeling process takes place on a microscopic scale throughout the body to keep bones alive and sturdy. During early childhood and in the teenage years, new bone is added faster than old bone is removed. As a result, bones become larger, heavier, and denser. Bone formation happens faster than bone resorption until you reach your peak bone mass (maximum bone density and strength), between the ages of 25 and 30 years. After this peak period, bone resorption occurs faster than the rate of bone formation, leading to net bone loss. Bone loss is most rapid in women in the first few years after menopause but continues into the postmenopausal years. In men, appreciable bone loss does not usually occur until the middle 70s. How are they used One or more of the bone marker tests may be ordered to help your doctor determine if you have increased rates of bone resorption and/or formation. Bone markers are sometimes used as an adjunct to bone density testing when doctors are evaluating whether or not your bones are thinning or if you have a bone disease. They are used primarily to monitor response to anti-resorptive therapy for bone disease and to help your doctor determine if the dose of the drug you are receiving is adequate. These tests can enable your doctor to quickly tell if you are responding to anti-resorption or bone formation therapies in a much shorter time period than the X-ray types of bone density testing (three to six months versus one to two years). This way, your therapy can be altered if you are not responding properly to it. Since breast and prostate cancer patients have a high incidence of bone metastases, there is also some evidence that bone markers can help doctors predict which breast and prostate cancer patients may be at high risk for complications from bone metastases and thus eligible for bone resorption sparing medications such as the bisphosphonates. Bone markers may also be able to predict a patients response to therapy for a bone loss condition.

Bone Diseases
Your bones help you move, give you shape and support your body. They are living tissues that rebuild constantly throughout your life. During childhood and your teens, your body adds new bone faster than it removes old bone. After about age 20, you can lose bone faster than you make bone. To have strong bones when you are young, and to prevent bone loss when you are older, you need to get enough calcium, vitamin D and exercise. There are many kinds of bone problems:
