How Does Osteoporosis Affect The Bone Matrix
Bone is a living growing tissue made mostly of collagen (protein that provides soft framework) & the mineral calcium phosphate that adds strength & hardens the framework. Two types of bone are found in the body; cortical (dense compact outer layer) & trabecular (makes up inner layer, ...Read more
Only partly: The dexa scan gives the bone mineral density at the hips, spine and forearm. These scores can predict osteoporosis: 't-score' of less than -2.5 is considered osteoporosis. However, many people suffer osteoporosis fractures despite having better bone densities. So, we also use other factors: age, ethnicity, size, family history, prior fractures, smoking, alcohol, other conditions to predict risks. ...Read moreSee 1 more doctor answer
Incr bone formation: Evidence shows that exercise help build and maintain bone density at any age. Studies have seen bone density increase by doing regular resistance exercises such as lifting weights for 20mi, 2-3 times a week. This type of weight-\bearing exercise appears to stimulate bone formation via bone stimulation through muscle contraction.Space zero gravity is an example of how bone density can be diminished. ...Read moreSee 1 more doctor answer

How does cancer chemotherapy affect the healing of a broken bone? Will the bone have to heal after chemo?

If i remember correctly it usually takes bones 4-6 weeks to heal. ...Read moreSee 1 more doctor answer
How does rods placed into the bone effect bone marrow? If bone marrow loss is a result of this condition, would that also cause anemia?
Probably not: Much. In the common situation where a rod is placed in the femur to stabilize a serious fracture there would be effacement of some bone marrow, but not enough in of itself to cause a deficit in rbc production leading to anemia. The fracture itself and the surgery could result in low HGB shortly after the injury. ...Read more
Varies: Osteosarcoma is a cancer that arises from the bone itself. It can grow locally and can symptoms, and it can potentially metastasize throughout the body. Treatment varies and is based in part on the staging of the cancer; but can involve surgery, radiation, and chemotherapy. ...Read moreSee 1 more doctor answer
Does the bone heal after posterior cervical disectomy, how long does it take the bone to grow back from this surgery.
Bones: Although there is at least one study which suggests that strontium ranelate may have a beneficial effect on the degeneration of spinal discs, by far the most well documented effect of strontium is on bones. Be aware that in europe, the use of strontium has been restricted due to evidence of increased cardiac risks with its use. ...Read more
