What is involved in having a bone density test?

The test uses X-rays to measure how many grams of calcium and other bone minerals are packed into a segment of bone. The bones that are most commonly tested are in the spine, hip and sometimes the forearm.

Does a bone density test hurt?

What happens if your bone density is low?

The most worrisome condition is osteoporosis, where low bone density causes holes inside the bone to widen and the outer walls of the bone (the cortex) to thin. This causes the bone to be more fragile. People with osteoporosis are at a much greater risk for fracture with little or no trauma.

Does a bone density test show arthritis?

A bone density test isn't typically used to diagnose arthritis. Instead, it's most often used to diagnose early signs of bone loss or osteoporosis. But if you have inflammatory types of arthritis, like RA or PsA, you may be at risk for developing osteoporosis.

What does a clicking knee mean?

The noise occurs because tiny air bubbles (nitrogen) accumulate within the fluid inside your joints and when you move, they collapse (or burst) due to the changes in pressure inside the joint. The noise occurs when the gas bubbles collapse. When the bubbles burst this is called 'cavitation'.

What does it mean when your knee makes a crunching sound?

The crunching you hear likely is due to the cartilage in your knee becoming rough, so the bones cannot slide as easily in the joint as they normally do. Knee crepitus typically happens when the knee is bent, such as when you are squatting, going up or down stairs, or rising from a chair.

What does it mean when your knee pops while walking?

Mechanical Popping
