What is the first treatment for thumb arthritis?

Thumb arthritis commonly affects the joint at the base of the thumb, where the thumb meets the wrist. Pinching, opening jars, turning keys and sustained gripping can load this joint and trigger pain. Early care aims to support the joint, reduce irritating force and preserve useful hand movement.

A clinician may check pinch strength, thumb alignment, movement and tenderness. The support chosen should fit the painful joint and still allow safe use of the fingers. Hand therapy can also teach joint-protection techniques and ways to adjust everyday tasks.

A [Splinting](/treatments/trauma-and-fracture-care/splinting/) plan may support the thumb during tasks or periods of pain. Use wider handles, avoid forceful key pinch and carry objects with the palm when possible. Break demanding activities into shorter periods and stop before pain escalates.

If symptoms continue to limit function, your clinician may discuss [Cortisone Injection](/treatments/non-surgical-orthopedics/cortisone-injection/). Surgery such as [Joint Fusion Surgery](/treatments/reconstructive-orthopedic-surgery/joint-fusion-surgery/) is generally a later discussion for selected joint damage and functional needs, after an examination.

Arrange an assessment when thumb pain persists, grip is becoming weaker, or routine tasks are increasingly difficult. Seek prompt care after an injury with sudden swelling, deformity or loss of movement. New numbness, a cold or pale thumb, or rapidly worsening pain also needs urgent review.

Which thumb joint is affected? When should I wear the splint? How can I protect pinch strength, and when would an injection or surgery be considered?
