CMC joint pain, also known as thumb arthritis, can be caused by a variety of factors. One of the most common causes is repetitive gripping or pinching motions over a long period of time. This can put excessive stress on the thumb joint, leading to wear and tear of the cartilage and the development of arthritis.
Activities that involve repetitive thumb movements, such as using scissors, driving, or writing with a pen or pencil, can contribute to the development of CMC joint pain. These activities often require a significant amount of force and can lead to inflammation and joint damage over time.
Another factor that can contribute to CMC joint pain is age. As we get older, the cartilage in our joints naturally starts to wear down, making them more susceptible to arthritis. The CMC joint is no exception, and the wear and tear of the joint can lead to pain, stiffness, and decreased range of motion.
In some cases, CMC joint pain may also be caused by injury or trauma to the thumb. This can include fractures, sprains, or dislocations, which can damage the joint and lead to the development of arthritis.
Additionally, certain medical conditions can increase the risk of developing CMC joint pain. These include rheumatoid arthritis, which is an autoimmune disorder that causes inflammation in the joints, as well as osteoarthritis, a degenerative joint disease that commonly affects the thumb joint.
It’s important to note that while these factors can increase the risk of developing CMC joint pain, not everyone who engages in repetitive thumb movements or has these risk factors will develop arthritis. Each person’s individual anatomy and genetic predisposition can also play a role in the development of joint pain.
CMC joint pain is most often caused by repetitive gripping or pinching motions over a long period of time. This can lead to wear and tear of the joint, inflammation, and the development of arthritis. Age, injury, and certain medical conditions can also contribute to the development of CMC joint pain. It’s important to be aware of these risk factors and take steps to prevent or manage joint pain if necessary.
