Can your bones shrink as you get older?

Both men and women tend to shrink as they age, due to deterioration of the vertebrae and the discs between them, both of which cause shortening of the backbone. Also, women are somewhat more prone to osteoporosis, which accelerates the deterioration, and they tend to be shorter to begin with, making some older women seem especially tiny. well i think that it matter how they eat. Plus at a certain age the stop growning.

Is a cast needed for a sprained ankle?

If this just happened, ice-pack it for 30 minutes before bandaging. If you're using tape to immobilze or brace, here's what you do: * Use 1" or 2" tape, if you can. * Tape first from just above the ankle, down the leg and wrap under the heel -- then back up the other side of the leg, so the first bandage runs parallel to the leg and wraps under the heel. * Next, tape from the side of the foot back wrap around the heel, and up the other side of the foot. This piece of tape is parallel to the foot and at right angles (perpendicular) to the first piece of tape. * Repeat this process so there are 4 pieces of tape in each direction -- a total of 8 peices of tape. Vertical, horizontal... vertical, horizontal, and so on. * Finish by running a circle of tape around the ends of the other tape so they won't come off easily (two circles because there are two places where tape ends show). * Make certain that the tape isn't reducing circulation. If you're using an Ace Bandage, KoBan, or elastic wrap: * make a circle around the instep of the foot, so that the bandage overlaps itself and stays in place. * Now, wrap a circle around the ankle. * Repeat until you've used the entire bandage. Be very careful not to stop blood circulation. * Secure the bandage around the ankle. Check frequently for circulation. Personally, I prefer the elestic wraps if the victim has to walk (if you're backcountry hiking for instance), as they flex and are less likely to trip the victim, causing a fall. The tape method, however, has worked for years and is better for immobilization.

Small hard lump on the left side of your head a little above your ear It does not hurt when you touch it It has been there for a few years Should you be concerned?

I don't know, but I have the same thing. Mine is a fixed lump with no underlying bone damage. The surgeon wasn't sure what it was because mine was hard and fixed while a bump on the temporal bone is usually movable and not so firm...usually an oil deposit. She said as long as it does not grow, she sees no reason to have it removed. You should check with a doctor though.

How long does it take for fracture on the lower one third of fibula bone to heal?

The "fibia" is not a bone. There are 2 bones that make up the lower leg, the tibia and fibula. The fibula is not a weight bearing bone and doctors usually dont do anything about it. The fibula is weight bearing, and depending on age, it usually heals in about 6 weeks. But that doesnt mean that it doesnt still hurt. If the patient is geriatric age, their bones take longer to heal.

What is the purpose of a bone biopsy?

There are several different types of biopsies.A needle (percutaneous) biopsy removes tissue using a hollow tube called a syringe. A needle is passed through the syringe into the area being examined. The surgeon uses the needle to remove the tissue sample. Needle biopsies are often done using x-rays (usually CT scan), which guide the surgeon to the appropriate area. An open biopsy is a surgery that uses general anesthesia. This means you are asleep and pain-free during the procedure. The procedure is done in a hospital operating room. A surgeon makes a cut into the affected area, and the tissue is removed. Closed biopsy uses a much smaller surgical cut than open biopsy. A small cut is made so that a camera-like instrument can be inserted. This instrument helps guide the surgeon to the appropriate place to take the sample. A biopsy are most often done to examine tissue for disease. A biopsy may also be done to match organ tissue before a transplant.
