Osteoarthritis of the joints of the hand
Osteoarthritis of the hand, also known as "wear and tear" arthritis, happens when the cartilage that cushions the ends of the bones in the hand joints gradually wears away.
Sign and Symptoms
- Pain: Often worse with activity or at the end of the day.
- Stiffness: Especially after rest, which may improve with movement.
- Swelling: Can be hard and knobbly due to bone growth or soft due to fluid buildup.
- Reduced grip strength and range of motion: Making it difficult to perform daily tasks.
- Deformity: Joints may become misaligned or develop bony enlargements (Heberden's and Bouchard's nodes).
Why it Happens?
- Ageing: As we age, the cartilage in our joints naturally deteriorates, making us more susceptible to osteoarthritis.
- Overuse and Repetitive Movements: Activities that involve repetitive hand motions, like typing, using tools, or certain sports, can accelerate cartilage breakdown and contribute to osteoarthritis.
- Joint Injuries: Past injuries to the hand or wrist, such as fractures or dislocations, can damage cartilage and increase the risk of developing osteoarthritis later in life.
- Genetics: Some individuals may inherit a predisposition to osteoarthritis, making them more likely to develop the condition, even at a younger age.
- Obesity: Excess weight can put additional stress on the hand joints, potentially accelerating cartilage damage and increasing the risk of osteoarthritis.
