What Causes Joint Cracking? ------------------------------------------------------------------------------ QUESTION: Every so often, after sitting around for a while, and then getting up to walk about, I feel and actually hear a cracking sound in my hip. I know I am not imagining this, as my wife can hear it to. It doesn't hurt but it isn't a pleasant experience. Do you know what causes this and if it is a serious situation? ------------------------------------------------------------------------------ ANSWER: Sounds which come from the joints are not too uncommon, especially in people with a bit of arthritis. There are a number of causes, and none of them are too serious. If the surfaces inside the hip have become worn and damaged by arthritis, there can be a sound created by the rough surfaces grinding against one another. Some times there are loose bodies, bits of cartilage or bone, that float around inside the joint space and can cause a sound as they are moved about by the motion of walking. Most of the time, however, the sounds are made by the tendons and muscles around the joint as they slip over a bump on the bone. Near the hip joint is a sac called a "bursa" over which tendons pass. If it is inflamed, it too may be a source of sound. While the sound may be startling at times, it is usually of little consequence and should not cause you any undue concern. ---------------- The material contained here is "FOR INFORMATION ONLY" and should not replace the counsel and advice of your personal physician.
