The acromio-clavicular joint is located at the top of the shoulder, between the collarbone and top of the shoulder blade. The AC joint is most commonly injured during sports, but can also be caused by motor vehicle accidents or falls. This dislocation is one of the most common shoulder injuries orthopedic surgeons treat.

For minor AC joint dislocations, surgeons often suggest patients wear a sling for a few weeks and undergo physiotherapy rather than undergo surgery using a plate and screws. Severe dislocations are often treated with surgery but new research finds that patients who opt for non-surgical treatment typically experience fewer complications and return to work sooner. 

Vitamin D is important for the absorption and metabolism of calcium, as well as for maintaining healthy bones and muscles.  It's important but different parts of America have varying levels of it, and that is the main source, so we fortify products like milk with it.

In Denmark, the sun is absent for much of the year so people generally have too low a level, but are consumers actually interested in buying foods with added vitamin D?

A team of paleontologists find in a new fossil study that the extraordinary regenerative capacities of modern salamanders are likely an ancient feature of four-legged vertebrates that was subsequently lost in the course of evolution.

Ivermectin, a workhorse of a drug that a few weeks ago earned its developers a Nobel prize for its success in treating multiple tropical diseases, is showing early promise as a novel and desperately needed tool for interrupting malaria transmission, according to new findings presented today at the American Society of Tropical Medicine and Hygiene (ASTMH) Annual Meeting.

Only 2 percent of Internet pages with information on firearm storage correctly identified all four practices that encompass safe gun storage.

In frontier days, gun safety was a given but in the modern era most kids don't grow up around guns - and movies contain a lot of gun violence without any real exposure to the consequences so children unfamiliar with firearms may regard them as toys or not realize that are loaded.

Women are more likely than men to have a bachelor's degree and a white-collar job. They are also more likely to earn less than male counterparts, finds a new study spanning two generations in the United States.

The scholars analyzed U.S. Census socioeconomic data of more than 180,000 people at two points in time. The study looked at Latino and Asian immigrants in 1980 and then at their children's generation 25 years later (in 2005), as well as non-Hispanic whites whose parents were not immigrants.

In 1980, men led women by a significant margin in bachelor's-degree attainment, white-collar jobs and earnings, the study found. This held true for all three groups: Asians, Latinos and whites.
