Basal thumb arthritis, also known as thumb carpometacarpal (CMC) arthritis, occurs when the cartilage in the joint at the base of the thumb wears down. This leads to pain, stiffness, and difficulty with grip and pinch movements. It is a common condition, especially in older adults and those who perform repetitive hand activities.

Symptoms of Basal Thumb Arthritis:

• Pain and swelling at the base of the thumb
• Difficulty gripping, pinching, or opening jars
• Stiffness and reduced range of motion in the thumb
• A grinding or clicking sensation in the joint
• Progressive weakness in the thumb and hand

Causes and Risk Factors:

• Aging and natural wear-and-tear of the joint
• Repetitive thumb movements or overuse
• Family history of arthritis
• Previous thumb injuries
• More common in women over 40

Diagnosis:

Your surgeon will examine the thumb for pain, swelling, and mobility issues. X-rays may be used to assess joint damage and confirm the diagnosis.

Treatment Options:

Non-Surgical Treatments:

• Anti-inflammatory medications for pain relief
• Thumb splints or braces to support the joint
• Hand therapy and exercises to strengthen the thumb
• Corticosteroid injections to reduce inflammation
• Ice and heat therapy for symptom relief

Surgical Treatment

• In severe cases, procedures such as ligament reconstruction, joint fusion, or joint replacement may be considered to relieve pain and improve function.
