Living in a sunny climate does not improve vitamin D levels in hip fracture patients

19.03.2013
While it is well known that a majority of hip fracture patients of all ages and both sexes have insufficient or deficient levels of vitamin D, a new study presented today at the 2013 Annual Meeting of the American Academy of Orthopaedic Surgeons (AAOS) looks at whether or not living in a warm, sunny climate improves patient vitamin D levels.

Researchers retrospectively reviewed the vitamin D levels of 1,539 patients, including 448 acute hip fracture patients and 1,091 total hip (THR) or total knee replacement (TKR) patients, from December 2010 to December 2011 at a major medical center in southern California.

Patients were categorized based on their vitamin D levels – deficient, insufficient or sufficient – and according to age and sex. The mean vitamin D levels for the hip fracture and the THR and TKR patients were 26.38 ng/mL and 29.92 ng/mL, respectively. More patients in the hip fracture group were deficient or insufficient (65.8 percent versus 54 percent), and patients age 71 years and older were more deficient or insufficient in the hip fracture group than the joint replacement group (66.7 percent versus 47.13 percent).

Overall, the majority of patients age 18 and older of both sexes with hip fractures had insufficient levels of vitamin D, and those age 71 or older had significantly lower levels than the control group of THA and TKA patients.

A Nation in Motion
More than one in four Americans have bone or joint health problems, making them the greatest cause of lost work days in the U.S. When orthopaedic surgeons restore mobility and reduce pain, they help people get back to work and to independent, productive lives. Orthopaedic surgeons provide a great value, in both human and economic terms; and access to high-quality orthopaedic care keeps this "Nation in Motion."

Im Focus: Elucidating the Atomic Mechanism of Superlubricity

The phenomenon of so-called superlubricity is known, but so far the explanation at the atomic level has been missing: for example, how does extremely low friction occur in bearings? Researchers from the Fraunhofer Institutes IWM and IWS jointly deciphered a universal mechanism of superlubricity for certain diamond-like carbon layers in combination with organic lubricants. Based on this knowledge, it is now possible to formulate design rules for supra lubricating layer-lubricant combinations. The results are presented in an article in Nature Communications, volume 10.

One of the most important prerequisites for sustainable and environmentally friendly mobility is minimizing friction. Research and industry have been dedicated...
