How is thumb arthritis managed?

Thumb arthritis, also known as basal joint arthritis, is a common condition that affects the joint at the base of the thumb, known as the carpometacarpal (CMC) joint. This joint allows for the thumb's wide range of motion, enabling tasks such as gripping, pinching, and grasping. Over time, wear and tear or injury to the joint can lead to the breakdown of cartilage, causing pain, stiffness, and swelling.

One of the earliest signs of thumb arthritis is discomfort at the base of the thumb, particularly during activities requiring pinching or gripping, such as opening jars or turning doorknobs. As the condition progresses, pain may persist even at rest, and swelling or tenderness around the joint may occur. In advanced stages, deformity of the thumb and loss of function can significantly impact daily activities.

The diagnosis of thumb arthritis typically involves a combination of a physical examination and imaging studies, such as X-rays, to assess the extent of cartilage loss and joint damage. Treatment options depend on the severity of symptoms and the impact on daily life. Non-surgical approaches are usually the first line of treatment and may include activity modification, splinting, physical therapy, and medications such as nonsteroidal anti-inflammatory drugs (NSAIDs) to reduce pain and inflammation. Corticosteroid injections can provide temporary relief for more severe symptoms.

If non-surgical measures fail to provide adequate relief, surgical options may be considered. Surgery may involve removing the damaged joint surfaces and reconstructing the joint with tendon tissue or performing a joint replacement to stabilise the thumb. Advances in surgical techniques have improved outcomes, often restoring function and reducing pain significantly.

Managing thumb arthritis often involves a combination of self-care, medical treatment, and, in some cases, surgery. Early diagnosis and intervention are key to preventing progression and maintaining thumb functionality. By working with a healthcare provider, individuals with thumb arthritis can develop a comprehensive treatment plan tailored to their needs, allowing them to continue enjoying their daily activities with minimal discomfort.
