Understanding Unilateral Primary Osteoarthritis of the First Carpometacarpal Joint

Unilateral Primary Osteoarthritis of the First Carpometacarpal Joint, also known as thumb arthritis, is a condition that affects the joint at the base of the thumb. This condition occurs when the cartilage that cushions the joint wears away, leading to pain, stiffness, and limited mobility.

This type of arthritis is more common in women than men and typically affects individuals over 40 years of age. The causes of primary osteoarthritis of the first carpometacarpal joint are not fully understood, but it is believed to be a combination of genetic and environmental factors.

  1. Pain and tenderness at the base of the thumb
  2. Stiffness and decreased range of motion in the thumb
  3. A grinding sensation when using the thumb
  4. Swelling and inflammation around the thumb joint

If left untreated, Unilateral Primary Osteoarthritis of the First Carpometacarpal Joint can lead to more severe symptoms, such as weakness in the thumb and difficulty performing everyday tasks.

Treatment options for thumb arthritis may include:

  1. Nonsteroidal anti-inflammatory drugs (NSAIDs) to reduce pain and inflammation
  2. Splinting or bracing to support the thumb joint
  3. Physical therapy to improve strength and range of motion in the thumb
  4. Injections of corticosteroids to reduce inflammation
  5. Surgery, in severe cases, to remove and replace the affected joint

It's important to seek treatment for Unilateral Primary Osteoarthritis of the First Carpometacarpal Joint as soon as possible to prevent further damage to the joint and to improve quality of life. Your healthcare provider can help determine the best course of treatment for your specific situation.
