Having long ring fingers may raise your risk of developing the most common form of arthritis. A new study suggests that if your ring finger is much longer than your index finger, you double your chances of developing osteoarthritis in the knees. Researchers at the University of Nottingham looked at over 2,000 people considering joint replacements and more than 1,000 people with no symptoms. They found that men were more likely to have shorter index fingers, but they also discovered that women are more at risk than men. More information is available in the current issue of Arthritis and Rheumatism.
