What Is Bone Resorption And Bone Formation Defect If Osteoporosis
One process is: Greater. In osteoporosis, bone resorption is more prevalent then bone formation. As a result, a negative bone balance occurs and bone loss will occur and over time osteopenia or osteoporosis will occur. Medications such as Fosamax and Boniva (ibandronate) slow down bone resorption. ...Read more
Bone resorption usually refers to bone mineral reduction because cellular components osteoclasts remove calcium from bones into blood. Bone resorption exceeds formation in older patients due to hormonal imbalance, lack of exercise, and possibly nutrition and vit. D deficiency. Hyperparathyroidism sometimes related to renal disease, chronic inflammation, disuse ...Read more
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
Trauma to the bone: Bone marrow edema is the bone respondence +to some traumatic event, not strong enough to produce a fracture but sufficient to create the bone respond.Treatment is the same than afracture that is rest and the use of a cam-walker to unload the calcaneous. ...Read moreSee 2 more doctor answers
Metabolism: Bone is living tissue, and bone metabolism simply refers to the cellular activity of bone, whether that bone is healing from a fracture or responding to the normal activities of everyday life. In fracture healing, a combination of osteoblastic (bone forming) and osteoclastic (bone breakdown) activity occurs which ultimately leads to healing of the bone. ...Read moreSee 1 more doctor answer
After bunion surgery, my bone fused with pseudo bone. Now there is a bone spur, or growth on top of that joint. What can be done?
Depends: Discuss with your operating surgeon about any questions you have regarding surgical outcomes and possible necessary steps to address this issue. ...Read more
Defect size: Based on your question, i would assume that your specific situation requires a significant amount of bone, since your doctor is considering a hip bone graft. Good results can be achieved with different bone types, including cadaver bone. However, the larger the defect size, generally better results will be achieved using your own bone. ...Read moreSee 2 more doctor answers

One of it : Evista (raloxifene) or Raloxifene is a selective estrogen modulating drug , used in post menopausal breast cancers, is slightly better than tomaxifen in certain aspects, like reducing osteoporoses, reduce the incidence of fractures, has to be used with caution , in presence of vascular , renal & heart diseases may cause lethal thromboembolism.

What is the appropriate management of periodontal disease where there is horizontal bone loss and vertical bone loss?
You NEED a Dentist: There is absolutely no way for you to take care of this condition yourself. You need professional dental care. Maybe even a periodontist (gum/bone specialist). Also, you need on-going care for the rest of your life, since there is no "cure" for this condition yet. It can be improved and maintained, but it requires immediate, assertive, and on-going professional care. Without that, bye bye teeth. ...Read moreSee 2 more doctor answers
Filling a bone void: Doctors use to use bone from our shin or pelvis to fill holes in bones or add to bones that were not healing. Now we usually use freeze dried bone from cadavers and chemicals called bone growth factors to enhance the healing. This avoids the second surgical site and the pain of harvesting the bone. ...Read moreSee 1 more doctor answer
Augment bone H/W: Bone graft is used to augment bone height and/or width. Bone is harvested from a donor site (if use your own bone) or from other source and placed into the recipient site. Membrane, mesh, screw can be used to stabilize the graft insure the optimal result. Tissue suture then must provide the complete coverage with primary intention is possible. Finally, the graft must be protect from infection. ...Read moreSee 1 more doctor answer
Is it "better" to have sclerotic bone lesions, than lytic ones with bone metases? Is there still a greater chance of fracture of the affected bone, whether it is lytic or now sclerotic?
Good question: Excellent question.Unfortunately not an easy answer. But overall, either will do structural damage to the bone and leave it more vulnerable to a fracture or collapse.The lytic ones are quite a bit weaker,however, and can break with little or even no trauma.Both can be very painful and difficult to treat.Also,remember the source: breast,prostate,lung,thyroid, and kidney are more apt to go to bone. ...Read more
Does 'open' reduction with intramedullary nailing of tibial shaft fracture causes muscle weakness and slow bone healing due to soft tissue damage?
Not common: If the fracture is truly closed, bacteria should not be able to infect the bone since it isn't exposed to the outside environment. Fractures, where bone is penetrated through the skin or visible through a wound, have variable infection rates based on the size of the wound and the time until the patient receives antibiotics. ...Read more
Which type of avn is more dangerous, lead to collapse of talus bone. Patchy avn or diffuse avn ? How to care it ?
All avn is not good: Avascular necrosis means loss of blood supply to that area. Patchy or diffuse doesn't matter, except that patchy might indicate that blood supply is starting to return to the area. When the bone doesn't get the blood supply, the bone starts to demineralize making it appear "patchy" at first. If blood supply is not restored, the calcium in the bone will continue to be absorbed and collapse. ...Read moreSee 1 more doctor answer
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
