The latest news about calcium and vitamin D may not look so encouraging, but most experts say the take-home message is the same: Keep taking your pills.The biggest study ever to examine the value of the supplements suggests they convey only limited protection against broken bones.

Orthopaedic surgeons from Children's National Medical Center are part of a team of researchers that has identified the genetic mutation causing Proteus syndrome, a rare disorder in which tissue and bone grow massively out of proportion.The discovery appears in the July 27, 2011, online edition of the New England Journal of Medicine. The study, led by researchers at the National Human Genome Research Institute (NHGRI), part of the National Institutes of Health (NIH), may have larger implications in both the identification and treatment of Proteus syndrome, as well as for certain types of cancer.

Researchers from NYU Langone Medical Center's Departments of Orthopaedic Surgery and Radiology found that advanced MRI techniques can be used to detect subtle changes in joint cartilage microstructure and provide physicians a diagnostic tool for finding key markers of early osteoarthritis (OA). By using these techniques during patient exams to identify OA earlier, clinicians can shift the management of the disease from eventual joint reconstruction to long-term preservation.
