What is a Bone Density Test? How does the doctor choose where to scan you (wrist, ankle, hip)? What is the difference between this and a bone scan?
What is a Bone Density Test?
A bone density test is an examination by either special x-rays or ultrasound to determine how much bone mineral content (calcium and other minerals) is present in any section of bone. The higher the mineral content, the denser the bone. This is one of the ways to determine the risk of fracture.
What are the different types of bone density tests and what are the differences between them?
There are various types of tests available, peripheral and central . The peripheral devices measure the finger or ankle, and these central devices measure the spine and hips.
The peripheral devices are significantly cheaper and are easier to use; however, they are often used for screening for they do not measure the actual areas where fractures occur. This i...
Bone graft is often needed during orthopedic surgery. Bone removed from one site and grafted to another in the same patient is called autologous . Autologous bone graft is a good option for reconstruction of bone defects and breaks that don't heal. The iliac crest is the most commonly used site of donor bone. This is the boney bump felt in front of the hip. It's easy accessibility makes it a good choice. The down side is the possible side effects. Pain at the donor site is the most common problem. Reducing postoperative pain helps give patients a faster recovery time. In this study, researchers try using a continuous local anesthetic at the donor site to manage pain. Two groups of patients are compared. All patients received systemic medications for pain control. The morphine-based drug was delivered through a self-controlled pain pump. Everyone also had an infusion pump placed directly into the wound. This device was put in place during the operation as the wound was closed. Delivery ...
Your bones are not dead, static pieces of framework; your bones are alive and can be a source of pain. When you think about bone pain, you might remember a time when you broke a bone. But there are other times when bone pain happens. And when you do experience bone pain, there are some specific treatments to relieve it too.
Let’s first start with the list of catastrophic conditions that can cause bone pain. On top of that list is the most feared of all, cancer. Primary bone cancer or cancer that has spread to the bone (metastatic cancer) is very painful and is the first problem to rule out. Blood test, biopsies and imaging studies might all be necessary to find this sinister cause of bone pain. An equally concerning problem that leads to bone pain is a bone infection ( osteomyelitis ). In other parts of the world, tuberculosis (TB) is the most common cause of bone infections. But even in parts of the world where TB is almost unheard of, bone infections are not unheard of es...
