Basal Joint Arthritis / Thumb Arthritis Surgery

Basal joint arthritis is a degenerative process that takes place at the base of the thumb. It usually begins with intermittent pain in the thumb with repetitive or forceful motions. Patients may initially complain of pain with trying to open a tight jar or carrying a heavy load. As the arthritis progresses they may notice pain with opening doors, turning car keys, and may also feel a grinding sensation with thumb motion.


Generally, the disease process starts gradually beginning with intermittent symptoms that may become more frequent over time. Basal joint arthritis can affect one or both hands, but many times symptoms will be noticed earlier on in the dominant hand. This type of arthritis can be addressed in many ways depending on the severity and dysfunction the patient is experiencing. We will discuss the treatment options in further detail, but first we want you to gain a simple understanding of the disease process.

Cartilage is a smooth rubber-like tissue that cushions joint surfaces. Arthritis occurs when cartilage in a joint wears down. Eventually, the two bone surfaces are rubbing against each other when the joint moves. In basal joint arthritis, the base of the first metacarpal bone and the trapezium, a small carpal (wrist) bone beneath the thumb, begin to rub against each other. This rubbing is the source of the pain which may be felt as an aching, stabbing, or intermittent. Over time the space that was once between those bone disappears and they are resting against one another. Your thumb may feel weak and have decreased range of motion. This condition usually develops over time, but in some cases it may first be noticed after trauma or injury.

Basal joint arthritis can be diagnosed through careful examination of the hands and thumbs. X-rays are helpful in obtaining a definitive diagnosis and gives your doctor a better idea of how far the arthritis has progressed. X-rays will clearly show that the space between the two bones has deteriorated and may reveal bone spurs as a result. Our offices are equipped with fluoroscopy machines that allow us to take low dose radiation images of the hand during your appointment.


Treatment of basal joint arthritis depends on the patient, the severity of symptoms, and the stage of the disease process. Usually, initial treatment is conservative and consists of bracing and cortisone injections. Cortisone injections are given into the joint and help to decrease inflammation and pain in the area. Many times patients will have long term relief following an injection, but in more advanced cases the relief may not last as long or at all. Our doctors will image your hand through fluoroscopy while doing the injection to ensure the cortisone is injected into the exact location of your arthritis. If symptoms persist or worsen over time you may be a candidate for surgery.

Surgery usually involves removing a small carpal bone called the trapezium that sits at the base of your thumb and is the source of pain in basal joint arthritis. Removal of this bone does not alter the mobility or function of the thumb but does alleviate your pain. Once that bone is removed, the thumb metacarpal will be suspended in a variety of ways that may involve a tendon transfer, pinning or a tight rope suspension. All of these are appropriate options, although some may allow for earlier motion than others. Your doctor will discuss the surgery they think is right for you.


Physical therapy will be a large part of your rehabilitation process regardless of the specific type of surgery done. Hand therapists in particular are specifically trained in this type of rehabilitation. They will design a therapy program that is tailored to your needs and goals. They may also make a custom splint that can be worn during the beginning stages of recovery if advised by your doctor. Certified hand therapists have a wide array of skills, tools, and modalities that are specific to regaining fine motor skills, hand strength, and dexterity.

Thumb arthritis can be extremely painful and cause serious dysfunction for patients. Our goal at TOA is for you to return to the things you love!
