Did you know that the bone can get bruised? Now that we have technology like magnetic resonance imaging (MRI), discoveries like bone bruising are possible. What does it look like on the MRI? MRIs are made of signals that show up as an image on the computer screen. The signals have various levels of intensity from light to dark. Changes in the signal pattern alert the radiologist to any problems.In the case of bone bruises, blood pooling, fluid build up (swelling), and increased blood flow to the area show up on the MRI. Water that moves seen within the bone marrow (center of the bone) is another sign of bone bruising. If the injury is severe enough, there can even be tiny fracture lines in the bone referred to as microfractures.Traumatic bone bruises of the knee are the subject of this article written by two orthopedic surgeons. One surgeon is from Harvard Medical School (Boston). The other hails from Vanderbilt Sports Medicine Center at the Vanderbilt University Medical Center in Nas...
Bone graft material is used whenever there's a need for extra bone to support a fracture site or defect in the bone. It's easily available (taken from the patient's pelvic bone) and inexpensive. And it is bone inductive (fosters bone growth) to provide structural support to the damaged area.The downside is that the graft site can be painful for a very long time. In some cases, infection can delay recovery. Patients often report difficulty walking due to the pain. And the combination of pain and impaired walking result in loss of function.To help patients avoid the major and minor complications of bone graft, scientists are exploring the use of bone substitutes. One of those bone substitutes (alpha-BSM) is the subject of this study. Patients with an acute fracture of the tibial plateau were the subject of this multicenter study. Twelve study sites from around the North American continent were involved. The tibial plateau is the flat top of the upper portion of the tibia (lower leg bone...
As women go through perimenopause and menopause, one of the emerging concerns is how to stop the loss of bone density. Experts are not sure what causes the extreme speed-up of bone breakdown after menopause. What we do know is that by age 65, approximately 30% of women have developed osteoporosis, while after age 80, 70% of women suffer from this situation.
There are lots of advertisements for drugs that can help slow bone loss, but the picture that is painted in these ads may not be so rosy. ABC News has broadcast a warning that long-term use (more than five years) of Fosamax or its generic alendronate may lead to bone fractures in the femur bone (the thigh). Based on this news, the U.S. Food and Drug Administration will research whether a link exists between the long-term use of certain osteoporosis drugs called bisphosphonates (which include Fosamax, Actonel, Boniva and Reclast) and this type of fracture.
