Treating Basal Joint Arthritis
Your treatment will depend on how severe the pain is and how worn the joint is.
If arthritis is diagnosed early, it often responds to treatment without surgery. Your doctor may put a splint on your thumb for 3-6 weeks. This limits movement and helps reduce the inflammation. You may also be given oral anti-inflammatory medication, such as aspirin. If your symptoms don't improve, your doctor may give you injections of an anti-inflammatory, such as cortisone.
The diseased joint is removed and replaced with a tendon graft taken from your wrist or arm. You'll have less pain and be able to use your thumb again.
If nonsurgical treatment doesn't relieve the pain and stiffness, or if arthritis has destroyed the joint, your doctor may recommend surgery. The diseased joint is removed. Then the joint is rebuilt, usually with a piece of tendon (graft) taken from your arm or wrist. Your arm, or sometimes your entire body, is anesthetized so you don't feel anything during surgery. You can probably go home the day of surgery.
First your hand will be wrapped in a dressing. Then you'll have a cast or a splint on your thumb for 3-6 weeks. This keeps the thumb stable while it heals. Once you can move your thumb, your doctor will give you exercises, or refer you to a physical therapist, to help strengthen the muscles and make the joint more flexible. Regaining use of your thumb will take time.
