Hand Osteoarthritis: Causes, Symptoms and Diagnosis

Quick Answer

Hand osteoarthritis is wear-and-tear arthritis of the thumb base and the end and middle finger joints. It causes pain with use, short-lived morning stiffness and bony nodes, and it is diagnosed from the pattern of joints involved, an exam and X-rays.

Osteoarthritis of the hand slowly changes the small joints of the fingers and thumb. Doctors sometimes call it digital osteoarthritis, and you may see it written as "digital arthritis." This guide explains which joints it affects, what it feels like, how it differs from rheumatoid arthritis and how it is diagnosed. A short section near the end covers embolization, a newer procedure that is still at an early stage of research. If that is what you came for, our hand arthritis embolization page covers it in full.

What hand osteoarthritis is

Osteoarthritis (OA) is often described as wear-and-tear arthritis. The American Academy of Orthopaedic Surgeons (AAOS) notes that it is much more common than rheumatoid arthritis, that it generally affects older people, and that it shows up in a predictable pattern in certain joints.

It is also very common. The CDC estimates that about 33 million U.S. adults have osteoarthritis of some joint, and the hands are among the places it strikes most often. A 2018 review in Nature Reviews Rheumatology called the hand the most commonly affected site.

How likely is it over a lifetime? In the Johnston County Osteoarthritis Project, a study of 2,218 adults aged 45 and older, the estimated lifetime risk of hand osteoarthritis that causes symptoms was 39.8%. It was 47.2% for women and 24.6% for men. In the Framingham study of 1,041 people aged 71 to 100, 26.2% of women and 13.4% of men had symptomatic hand OA, and it was linked to about 10% lower maximal grip strength.

No treatment makes osteoarthritis go away. Care is aimed at easing pain and keeping your hands useful.

Which joints it affects

Hand OA tends to settle in three places:

The base of the thumb. This is the first carpometacarpal (CMC) joint, also called the trapeziometacarpal joint, where the thumb meets the wrist.
The end joint of a finger, closest to the fingertip. Doctors call it the distal interphalangeal (DIP) joint.
The middle joint of a finger, called the proximal interphalangeal (PIP) joint.

A 2022 review describes three broad types of hand OA: nodal OA of the finger joints, thumb-base OA, and erosive hand OA, which is covered below. You can have more than one. Thumb-base arthritis behaves differently enough that we cover it on its own page, thumb arthritis embolization.

Symptoms: what it feels like

According to the National Institutes of Health and AAOS, common symptoms include:

Pain when you use the joint, which may ease with rest. It can be dull or burning and often shows up hours after heavy use, or the next day.
Stiffness in the morning or after rest that usually lasts less than 30 minutes.
Swelling, warmth, or a grinding feeling in the joint.
In more advanced arthritis, pain that wakes you at night.

At the base of the thumb, pain usually comes with gripping and pinching. Turning a key and opening a jar are the classic triggers. Pinch can feel weak, and a bump may form at the base of the thumb. AAOS notes that women are 2 to 3 times more likely to get thumb-base arthritis, usually after age 50.

Nodes and cysts

Over time the finger joints can enlarge and change shape. Bony lumps near the fingertip joint are called Heberden's nodes. Lumps on the middle joint are called Bouchard's nodes. Some people also develop a mucous cyst, a small fluid-filled bump near the end joint that can leave a ridge or dent in the nail.

Who gets it, and why it hurts

Hand OA is more common in women, especially after age 50. Body weight seems to matter as well. In the Johnston County study, lifetime risk was 47.1% in people with obesity and 36.1% in those without.

Worn cartilage is only part of the pain story. Laboratory research on osteoarthritic joints shows that inflammation in the joint lining drives the growth of new small blood vessels, and that sensory nerves grow alongside those vessels. Researchers think this may contribute to pain. Most of that tissue research was done in joints other than the hand.

There is some evidence from the hand itself that inflammation matters. In a 2019 randomized trial of 92 people with painful hand OA and signs of inflammation, 10 mg of prednisolone a day for six weeks eased finger pain more than a placebo did. It was a short trial, and it tells us about the role of inflammation, not about long-term treatment.

Erosive hand osteoarthritis

Erosive hand OA is the most aggressive form. It mainly affects women. Instead of creeping in, it can start abruptly with pain, swelling and redness in the finger joints. X-rays show erosions in the center of the joint, with shapes radiologists describe as "saw-tooth" or "gull-wing." In rare cases the joint fuses on its own. A 2024 review describes it as a form that leads to significant disability.

Because it can start with swelling and redness, a sudden change in your hands deserves a proper evaluation. It is one of the main reasons a sudden change in your hands deserves a proper evaluation.

How it differs from rheumatoid arthritis

Both conditions affect the hands, but they are different diseases with different treatments.

	Osteoarthritis	Rheumatoid arthritis
What it is	Wear-and-tear arthritis	A chronic autoimmune disease that can affect many parts of the body
How common	Much more common	Less common
Typical pattern	A predictable set of joints: thumb base, end and middle finger joints	Often starts in the small joints of the hands and feet, usually the same joints on both sides of the body
What happens in the joint	Bony enlargement and shape change over time	The joint lining swells
Treatment	Splints, exercise, anti-inflammatory medicines, injections and sometimes surgery	Specialized drugs prescribed by rheumatologists

The table follows the AAOS patient guide on hand arthritis. The difference matters for every treatment decision. It also matters for embolization: the published hand studies enrolled people with osteoarthritis only, and at least one study and one registered trial excluded rheumatoid and other inflammatory arthritis.

How hand osteoarthritis is diagnosed

Diagnosis starts with the pattern. Which joints hurt, how long morning stiffness lasts, whether there are nodes, and whether both hands are involved in the same way all point toward or away from OA.

X-rays usually confirm it. In research studies, hand OA was confirmed on X-ray and classified using American College of Rheumatology criteria. Doctors grade what they see with scales. The Kellgren-Lawrence grade is used for finger joints, and the Eaton classification is used for the base of the thumb. One thumb-base study, for example, enrolled people with Eaton stage II or III arthritis.

X-rays and symptoms do not always match. AAOS points out that some people have no symptoms even though their X-rays show advanced arthritis. That is why a diagnosis rests on your symptoms and exam together with the images.

If the pattern suggests rheumatoid or another inflammatory arthritis, the next step is usually a rheumatologist, since those conditions are treated with different medicines.

When to see a doctor

It is reasonable to have your hands evaluated if:

Pain with gripping, pinching or fine work keeps coming back or limits what you can do.
Pain wakes you at night.
A finger joint becomes painful, swollen and red over a short time.
The same joints on both hands are swollen, or your feet are involved too.
A bump near the end joint is changing your nail.

One reassuring point from AAOS: some people find that thumb arthritis symptoms go away over time, with or without treatment. Getting evaluated does not commit you to a procedure.

Treatment, and where embolization fits

Standard care includes splints, hand exercises and anti-inflammatory medicines, and sometimes a steroid injection. Surgery is considered when other treatments are not helping and joint damage is extensive. Our guide to hand arthritis treatment without surgery walks through what the guidelines recommend.

Embolization is an emerging option, not a standard one. In the published studies, a doctor placed a small needle or catheter in an artery at the wrist and delivered a material, in most studies a short-acting one, that briefly reduces blood flow in the abnormal small vessels around painful joints. The idea builds on the vessel-and-nerve research described above, and for the hand it remains a hypothesis.

The evidence so far is five small studies with 204 patients in total. None had a comparison group, and there is no randomized trial. In the largest, a 2023 retrospective study of 92 patients treated in Japan, 77% had their pain score drop by at least 2 points at 12 months, and average pain went from 7.8 to 4.0 out of 10. Pain was reduced, not removed. Without a comparison group, it is not possible to say how much of that came from the procedure. The American and European hand osteoarthritis guidelines do not mention embolization, and a 2026 independent review described the hand data as "hypothesis-generating."

Dr. David Fox, a board-certified vascular surgeon in Manhattan, evaluates patients for hand embolization when OA pain has not responded to standard care. You can read what the studies found in our research summary, or see how it is used in other joints in the embolization guide.

Frequently Asked Questions

What are Heberden's and Bouchard's nodes?

They are bony lumps caused by hand osteoarthritis. Heberden's nodes form at the joint closest to the fingertip, and Bouchard's nodes form at the middle joint of the finger.

How long does morning stiffness last with hand osteoarthritis?

The National Institutes of Health describes osteoarthritis stiffness as usually lasting less than 30 minutes, in the morning or after rest.

Is hand osteoarthritis the same as rheumatoid arthritis?

No. Osteoarthritis is wear-and-tear arthritis that appears in a predictable set of joints. Rheumatoid arthritis is an autoimmune disease that usually affects the same joints on both sides of the body and is treated by rheumatologists with specialized medicines.

What is erosive hand osteoarthritis?

It is the most aggressive form of hand osteoarthritis. It mainly affects women and can begin abruptly with pain, swelling and redness, with erosions in the center of the joint on X-ray.

Is embolization a standard treatment for hand arthritis?

No. It is an emerging option supported by five small studies with no comparison groups, and the American and European hand osteoarthritis guidelines do not mention it.
