The iliac crest is the most prominent part of the ilium, the largest of the three bones that make up the bony pelvis or hip bone.It is the curved part at the top of the hop that sits close to the skin and forms the wing-like part of the pelvis on which a person will sometimes rest their hands. Pain in the iliac crest can also radiate to other areas of the body, including the back, abdomen, and groin. The location where it is felt depends on what is causing the pain.

Researchers have developed a hydrogel that they believe could help to treat rheumatoid arthritis. A simple yet effective new treatment for rheumatoid arthritis may be in sight; researchers have now created a hydrogel that could absorb the excess joint fluid that arises with disease, as well as deliver medications to affected joints.Created by researchers from the Institute for Basic Science (IBS) in the Republic of Korea, the gel works by responding to nitric oxide, which is a gas that has been linked to the development of rheumatoid arthritis.

New research suggests that a little weekly exercise could lower the risk of depression. A new study that examined data from almost 34,000 people has found that as little as 1 hour of exercise each week, regardless of intensity, can help to prevent depression.Depression is a very common disorder, affecting around 6.7 percent of adults in the United States per year. The economic burden of this disease was estimated to be $210.5 billion in 2010 alone. At a global level, the World Health Organization (WHO) calculate that more than 300 million people live with the disorder.

Retrolisthesis is an uncommon joint dysfunction that occurs when a single vertebra in the back slips backward along or underneath a disc.Retrolisthesis is the opposite of spondylolisthesis, which occurs when a vertebra slips forward. Retrolisthesis occurs in the neck and shoulder area, known as the cervical spine, or the lower back, known as the lumbar spine. Retrolisthesis occurs less often in the center area of the spine or the thoracic spine, although it is possible.

New research has delved into the biology behind osteoporosis. Researchers have mapped a cell mechanism that plays a key role in age-related bone loss. They suggest that the results not only shed light on the biology of osteoporosis but should also help to develop new drugs to treat the disease.In the journal PNAS, scientists from both the University of Alabama at Birmingham and Zhejiang University in China explain how a protein called Cbf-beta is important for controlling the rate at which new bone cells replace old ones. Osteoporosis is a disease in which bones become weak and brittle, increasing the risk of fractures.

By strengthening our muscles, we improve our lifespan. New research provides a window into how, on a cellular level, exercise can improve muscle health and, ultimately, exercise capacity, which is "the best predictor of mortality in the general population."A new study published in the journal Nature Communications describes how exercise helps the body to keep the cells in the muscles healthy and strong. "Whether muscle is healthy or not really determines whether the entire body is healthy or not," says lead researcher Prof. Zhen Yan, of the University of Virginia School of Medicine in Charlottesville.
