Most people would be surprised to know that total hip replacements (THRs) have been around since the 1930s. Today's successful use of THRs reflects the many implant changes in design and materials that have taken place since those early attempts. In this article, orthopedic surgeons from the New York University Hospital for Joint Diseases review the history of THRs up to and including today's surface replacement arthroplasty (SRA). SRA is a type of hip replacement that replaces the arthritic surface of the joint. But it removes far less bone than the traditional total hip replacement. Because the hip resurfacing removes less bone, it may be preferable for younger patients who are expected to need a revision (second) hip replacement surgery as they get older and wear out the original implant. The surface replacement arthroplasty (SRA) is done by dislocating the femoral head out of the socket. Special powered instruments are used to shape the bone of the femoral head so that the new meta...
my 14 year old daughter has a bulging disc in her neck... this was found via mri... i dont recall any one incident that could of caused it... but she plays a lot of sports and i mean she plays hard... steals and slides in softball and very aggressive 3rd baser... for the last 3mo she has had this horrible migraine that is constantly throbbing in the back of her head and on the sides of head but low on the sides like right above her ears.. she explains it like a tight head band only in the back of her head...no med or chiro service or iv drugs administered in er work.. the pressure and pounding never stops... could it be from the disc in her neck? Dena.
Headaches that are described as a "tight band" are often tension-type headaches, not Migraine. Has a doctor diagnosed your daughter with Migraine? Patients who have disc problems should be evaluated for cervicogenic headache. You...
How It Happens The heart pumps blood enriched with oxygen and vital nutrients throughout the entire body by way of a network of arteries. The heart itself must also be supplied with oxygen-rich blood in order to perform its job. Heart disease occurs when blood flow to the heart is blocked due to fatty material building up in the arteries and eventually closing them off. This process is called atherosclerosis , or “hardening of the arteries.” The fatty buildup can eventually close the arteries off, or, if the fatty deposit breaks, a blot clot can form, which can also block the flow of oxygenated blood to the heart. As a result, the heart becomes badly damaged due to tissue death from lack of oxygen. Common Symptoms Chest Pain Cold sweats, shortness of breath and lightheadedness Heart attack Coronary heart disease commonly leads to heart attack. If you believe you are experiencing a heart attack, call 911 or contact your emergency response system immediately. Learn more about heart a...
