De Quervain’s tendinitis (tendinitis of the wrist) refers to inflammation of the tendons around the thumb. It is usually caused by repetitive stress, such as picking up a baby throughout the day. It is also commonly associated with conditions such as rheumatoid arthritis.

Treatment for de Quervain’s tenosynovitis focuses on conservative care, including anti-inflammatory medications and activity modifications. Thumb splints can be helpful at times to provide rest for the tendons in the wrist. Steroid injections may be indicated if symptoms do not improve with relative rest, therapy, and medications.
