Carpometacarpal Arthritis

What is Carpometacarpal Arthritis?

Carpometacarpal arthritis is an inflammation of the base of the thumb joint. This is a type of arthritis that can be caused by injury, repetitive stress, or a combination of these factors.

The carpometacarpal joint includes three bones: the metacarpal bone, the trapezium, and the trapezoid. The metacarpal bones are located on the palm side of your hand and they connect to your fingers. The trapezium and trapezoid are located on the backside of your wrist. They connect to your thumb.

Carpometacarpal arthritis causes pain in this area. It may also cause swelling, redness, heat, and stiffness in your thumb joints. You may hear a grinding sound when you move your thumb joints or feel pain when you pinch something between your fingers.

What are the types of Carpometacarpal Arthritis?

There are two types of Carpometacarpal Arthritis

  • Carpal Tunnel Syndrome, which is the result of pressure on the median nerve as it passes through the wrist. The median nerve is responsible for sensation and movement in your hand. When there’s too much pressure on this nerve, you may experience pain, numbness, tingling, or weakness in your thumb and fingers.
  • Carpometacarpal Osteoarthritis, which is caused by degeneration of the bones and joints at the base of your finger

What are the causes of Carpometacarpal Arthritis?

There are many different causes of this inflammation, including repetitive motion and injury.

The most common cause is trauma to the hand or wrist. This can be from falling on an outstretched hand, overexertion, or a blow to the wrist. Carpal tunnel syndrome and tendonitis can also lead to carpal bone arthritis.

Carpal bone arthritis can also be caused by diseases like diabetes, rheumatoid arthritis, and gout. Other causes include psoriasis and thyroid problems.

What are the symptoms of Carpometacarpal Arthritis?

The symptoms of Carpometacarpal Arthritis (CPA) vary based on which joint is affected and what activities caused it to flare up.

Symptoms include:

  • Pain at rest and when performing daily activities
  • Swelling at night that lasts longer than 30 minutes after waking up
  • Pain that increases with use
  • Pain while using tools or gripping objects tightly

What are the risk factors for Carpometacarpal Arthritis?

It can be caused by several factors, including:

  • Repetitive stress on the wrist and hands (such as from heavy lifting or gripping)
  • Carrying heavy bags on one side of your body
  • Having rheumatoid arthritis or gout
  • Gout
  • Osteoarthritis
  • Trauma to the hand or wrist
  • Rheumatoid arthritis

What are the exercises for Carpometacarpal Arthritis?

Carpometacarpal arthritis is a common condition that affects the base of your thumb. It can cause swelling, pain and stiffness in the joint where the carpal bones meet the metacarpals (bones in your hand).

There are a number of exercises you can do to help ease symptoms, including:

Finger stretching – gently stretch out each finger, holding for 20 seconds each time

Finger abduction – hold your hand up at shoulder height with your palm facing down, then straighten out each finger one by one to stretch them out

Finger extension – hold your hand up at shoulder height with your palm facing down, and then straightening out each finger one by one.

What are the treatments for Carpometacarpal Arthritis?

There are a few different treatment options for carpometacarpal arthritis.

  • The first is rest, which is often the best treatment for carpal tunnel syndrome. This will help reduce symptoms and allow the body to repair itself.
  • Physical therapy may also be recommended, as it can help strengthen the hand muscles and improve range of motion.
  • Other treatments include corticosteroids, which can reduce inflammation; nonsteroidal anti-inflammatory drugs; splints; and surgery.

What brace or splint is used for Carpometacarpal Arthritis?

Carpometacarpal arthritis is a disease that affects the wrist, thumb, and hand. Carpometacarpal arthritis is caused by wear and tear on the cartilage that protects your joints from bone rubbing against bone.

There are several options for treating this type of arthritis. One option is a thumb spica splint. This splint is used to treat carpal tunnel syndrome, which often occurs with carpometacarpal arthritis. The thumb spica splint provides support for your thumb joint while still allowing you to move your wrist freely.

The thumb spica splint has straps that surround the top and bottom of your thumb, as well as one strap that goes around the base of your wrist. The straps are adjustable so they can be tightened or loosened as needed to provide optimal comfort and support while also ensuring proper fit.
