Source: Medical News Today

A recent study reports that engaging in physical activity can reduce pain and help to maintain mobility and independence for older adults with arthritis, but current exercise recommendations are often unachievable for this population. Now, however, a new study finds that exercising for just 45 minutes a week is enough to reap the benefits.

The secret behind the toughness of deer antlers

Scientists from Queen Mary University of London (QMUL) have discovered the secret behind the toughness of deer antlers and how they can resist breaking during fights. The team looked at the antler structure at the 'nano-level', which is incredibly small, almost one thousandth of the thickness of a hair strand, and were able to identify the mechanisms at work, using state-of-the-art computer modelling and x-ray techniques.

Co-author Dr Ettore Barbieri, also from QMUL's School of Engineering and Materials Science, said: "Our next step is to create a 3D printed model with fibres arranged in staggered configuration and linked by an elastic interface.

The aim is to prove that additive manufacturing - where a prototype can be created a layer at a time - can be used to create damage resistant composite material."

Bone loss may be linked to Alzheimer's disease

Fewer than 5 percent of cases of Alzheimer's disease have a clear genetic cause, making it hard to predict who will develop the devastating brain-wasting disorder. There is an urgent need to develop biomarkers and early treatments before the symptoms of decline take hold and destroy lives. Now, using a mouse model of Alzheimer's disease, researchers discover a link between early bone loss and brain degeneration that may begin to address this need.

Osteoarthritis: New blood test detects early stages, study finds

There is currently no blood test for early-stage osteoarthritis, a degenerative joint disease where the cartilage that eases and cushions movement breaks down, causing pain, swelling, and problems moving the joint. Now, researchers at Warwick University in the United Kingdom have developed a blood test that can provide an early diagnosis of osteoarthritis and distinguish it from rheumatoid arthritis and other inflammatory joint diseases.

New "Fish Hook" Procedure for Mallet Finger

Source: Helio - Orthopedics

This study describes a new technique called the “fish hook” technique for the treatment of bony mallet finger. This technique catches the dorsal fragment with a bent K-wire shaped like a fish hook. Transarticular fixation is performed with another K-wire. This technique does not directly penetrate the bone fragment to prevent fragment comminution.

High cholesterol might harm more than our cardiovascular systems. New research using animal models, published online in The FASEB Journal, suggests that high cholesterol levels trigger mitochondrial oxidative stress on cartilage cells, causing them to die, and ultimately leading to the development of osteoarthritis.

Prevention of Thumb Web Space Contracture with Multiplanar External Fixation

Source: Techniques in Hand & Upper Extremity Surgery

Thumb web space contracture following hand trauma can be disabling with numerous reconstructive procedures existing to correct the resultant deformity. In this study, following marked soft tissue injury to the hand the Stryker Hoffmann II Micro External Fixator System was used to link the first and second metacarpals by a multiplanar system using 1.6 or 2.0 mm self-drilling half-pins and 3 mm carbon fiber connecting rods. This facilitated placement of the thumb in maximal palmar abduction and allowed adjustment of thumb position throughout the postoperative period.

Hand Dominance and Common Hand Conditions

Upper extremity disorders such as carpal tunnel syndrome (CTS), de Quervain's tenosynovitis (DEQ), lateral epicondylitis (LE), hand osteoarthritis (OA), and trigger finger (TF) are common diagnoses that lead patients to seek a hand surgeon for evaluation and treatment.1,2 Although there is a common perception that these disorders should affect the dominant hand more often, clinical experience suggests that this is not always the case; it is not seen as unusual for these conditions to present in the nondominant hand.

FDA requests additional information to address data gaps for consumer hand sanitizers

Source: MNT (Medical News Today)

The U.S. Food and Drug Administration has issued a proposed rule requesting additional scientific data to support the safety and effectiveness of certain active ingredients used in topical consumer antiseptic rubs (including hand sanitizers) marketed over-the-counter (OTC). The FDA's request for more data is intended to help the agency ensure that regular use of these products does not present unknown safety and efficacy concerns, and does not mean the FDA believes these products are ineffective or unsafe.
