Thumb Base Arthritis Treatment in Surrey, B.C.

Thumb base arthritis is a common form of osteoarthritis that affects the joint connecting the thumb to the wrist. This joint is known medically as the first carpometacarpal (CMC) joint and plays a critical role in gripping, pinching, and performing fine motor tasks. As the cartilage within the joint gradually wears down over time, the bones begin to rub together. This can lead to pain, swelling, stiffness, and reduced strength in the thumb. Everyday activities such as opening jars, turning keys, or writing can become increasingly difficult. At PSG, treatment for thumb base arthritis is tailored to the severity of symptoms and the functional needs of each patient. Our goal is to relieve pain, preserve thumb mobility, and restore comfortable hand use whenever possible.

What Causes Thumb Arthritis?

Thumb base arthritis most commonly develops due to gradual wear and tear in the joint over many years. Repeated use of the thumb can eventually lead to breakdown of the protective cartilage that cushions the bones of the joint.

In some cases, previous injuries may increase the risk of developing arthritis. For example, fractures involving the thumb joint can alter joint mechanics and contribute to earlier cartilage degeneration.

Treatment Options for Thumb Arthritis

In the early stages of thumb arthritis, treatment often focuses on reducing strain on the joint. Modifying certain activities or using adaptive tools—such as thicker pens or ergonomic devices—can help decrease pressure on the thumb. Splinting is also commonly recommended to support the joint and reduce pain during daily activities. In some cases, injections may be used to help manage inflammation and discomfort. When conservative treatments are no longer effective and symptoms begin to interfere with daily life, surgical treatment may be considered.

Thumb Arthritis Surgery

Surgical treatment for first CMC arthritis focuses on relieving pain while preserving as much thumb function as possible. One option is joint fusion, which permanently stabilizes the joint. This procedure can effectively eliminate pain and provide a strong, stable thumb, but it reduces mobility in the joint. It is typically recommended for patients who place very heavy demands on their hands.

A more commonly performed procedure involves removing a small wrist bone called the trapezium and reconstructing support for the thumb using a tendon from the wrist or nearby hand muscles. This technique relieves joint pain while preserving a greater range of thumb motion. Your surgeon will discuss which surgical option is most appropriate based on your symptoms, hand function, and lifestyle needs.

Recovery

Recovery following thumb arthritis surgery requires patience and careful rehabilitation. Patients typically wear a cast or splint for three to nine weeks following the procedure to allow the joint to heal properly. Hand therapy is often an important part of recovery and helps restore movement, strength, and coordination. In many cases, it may take three to six months before the hand feels fully functional again.

Possible Complications

As with any surgical procedure, there is a risk of infection. Temporary numbness may occur after surgery, but usually improves over time. Some procedures require small pins to stabilize the bones during healing, and these pins are typically removed at a later stage.

If the hand is used too aggressively during early recovery, the pins may bend or break, which can make removal more difficult. Swelling and stiffness may persist for several months in some patients, and tenderness near the surgical site can take time to fully resolve. Your surgeon will review all potential risks and expected outcomes during your consultation.
