Osteoarthritis of the hand is the gradual breakdown of cartilage in the finger and thumb joints, leading to pain, stiffness, swelling and weakened grip. It most often affects the thumb base and the small finger joints. Hand therapy can reduce pain and protect function. SportsMed Physical Therapy provides hand and occupational therapy at New Jersey and Connecticut locations.
What Is Osteoarthritis of the Hand?
Osteoarthritis of the hand is a degenerative joint condition in which the smooth cartilage covering the ends of the small hand bones thins and wears away. As cartilage is lost, joint spaces narrow, bone spurs form and the surrounding capsule thickens. Three sites are most commonly involved: the carpometacarpal joint at the base of the thumb, the distal interphalangeal joints closest to the fingertips, and the proximal interphalangeal joints in the middle of the fingers.
The hand is one of the most frequently affected regions in the body. Radiographic hand osteoarthritis appears in a large share of adults over 60, and symptomatic thumb base arthritis is especially common in women after menopause. Bony enlargements called Heberden nodes at the fingertip joints and Bouchard nodes at the middle joints are hallmark findings. Because the hand performs hundreds of precise tasks a day, even mild changes can affect opening jars, turning keys, buttoning shirts and typing.
What Causes Osteoarthritis of the Hand?
Hand osteoarthritis develops when the load placed on a joint over years exceeds what its cartilage can repair. Genetics play a large role, which is why the condition often runs in families and appears in similar joints across generations. Hormonal changes after menopause, previous fractures or ligament injuries, and decades of high-demand hand use all contribute. Thumb base arthritis is particularly linked to the joint’s saddle shape, which trades stability for mobility and depends heavily on ligament support.
Common causes and risk factors include:
- Age over 50, with risk rising each decade
- Family history of hand osteoarthritis or finger nodes
- Female sex, especially after menopause
- Prior finger fracture, dislocation or ligament sprain
- Repetitive pinching, gripping or vibration exposure at work
- Joint hypermobility or laxity at the thumb base
- Obesity and metabolic conditions such as diabetes
What Are the Symptoms of Osteoarthritis of the Hand?
Symptoms build slowly over years. Many people first notice morning stiffness that eases within 30 minutes, then aching after tasks requiring sustained pinch, such as gardening or using scissors.
Typical symptoms include:
- Deep aching pain at the thumb base, made worse by pinching or twisting
- Stiffness in the fingers, worst in the morning or after rest
- Weak grip and dropping objects such as cups or keys
- Bony bumps at the finger joints, sometimes with mild swelling
- Grinding or clicking with thumb or finger movement
- Difficulty opening jars, turning keys or fastening buttons
- Gradual loss of the ability to fully straighten or bend a finger
Seek prompt medical attention if a joint becomes hot, red and severely swollen, if you develop fever, or if several joints swell symmetrically with more than an hour of morning stiffness, since these suggest infection or inflammatory arthritis rather than osteoarthritis.
How Is Osteoarthritis of the Hand Diagnosed?
Diagnosis is largely clinical. A therapist or physician examines each joint for tenderness, bony enlargement, swelling and alignment, then measures grip and pinch strength and joint range of motion. The grind test, which compresses and rotates the thumb base, reproduces pain when the carpometacarpal joint is involved. X-rays confirm joint space narrowing, spurs and thumb base subluxation, though imaging severity often does not match symptom severity. Blood tests are ordered only when inflammatory arthritis, gout or psoriatic arthritis needs to be ruled out.
How Physical Therapy Treats Osteoarthritis of the Hand
Hand osteoarthritis responds well to conservative care, and a combination of splinting, exercise and joint protection education is recommended before injections or surgery. Our hand and occupational therapy team works specifically with the small joints of the hand and wrist and can fabricate custom orthoses.
Care usually begins with a thumb spica or finger orthosis to rest the irritated joint during aggravating tasks, along with heat, gentle joint mobilization and soft tissue work for the thenar muscles. Paraffin baths and contrast baths help some patients loosen stiff morning hands before exercise.
From there, therapy adds targeted strengthening of the first dorsal interosseous and opponens muscles, which stabilize the thumb base, plus tendon gliding and graded range of motion work for stiff fingers. Exercises are kept short and frequent, often five minutes a few times a day, because arthritic joints tolerate small doses better than long sessions. Joint protection training then changes how you grip: using larger handles, spreading load across both hands, sliding rather than lifting, and swapping pinch for palm-based holds. Therapists also recommend adaptive tools for cooking, gardening and computer work. Broader conditioning through physical therapy helps patients with arthritis in other joints, and people whose jobs involve heavy or repetitive hand use benefit from workplace injury rehabilitation.

How Long Does Recovery Take?
Most patients notice less pain within three to four weeks of splinting and activity change, with grip and pinch strength improving over eight to twelve weeks. Osteoarthritis is a lasting structural condition, so the goal is comfortable, capable hands rather than reversal of joint changes. Progress moves faster when the orthosis is worn as prescribed, exercises are done daily in short sessions, and heavy pinching tasks are modified rather than powered through. Progress slows with advanced joint deformity, continued high-load pinch at work, and long gaps between therapy sessions.

Frequently Asked Questions About Osteoarthritis of the Hand
Q: Does hand therapy actually help arthritis, or is surgery the only fix?
A: Hand therapy helps most people. Guidelines recommend orthoses, exercise and joint protection as first-line care for hand and thumb osteoarthritis. Many patients gain enough pain relief and strength to avoid or delay surgery for years, and those who do proceed recover better with prior therapy.
A: Very soon. Most patients begin moving the day of or the day after surgery in the hospital, then start outpatient or in-home therapy within the first week or two. Early motion and muscle activation strongly influence final range of motion after knee replacement.
Q: Should I exercise my hands if they hurt?
A: Yes, with the right dose. Gentle range of motion and targeted strengthening reduce pain and improve grip over time, while total rest leads to stiffness and weakness. The rule of thumb is that soreness should settle within an hour of finishing your exercises.
Q: Do thumb splints work for arthritis at the base of the thumb?
A: They help many patients. A custom or prefabricated thumb spica orthosis rests the carpometacarpal joint during pinching tasks and often reduces pain within a few weeks. Most people wear it during aggravating activities and at night rather than all day, so muscles stay active.
Q: Will hand osteoarthritis get worse over time?
A: Osteoarthritis is progressive on imaging, but symptoms do not always follow. Many people plateau or improve with joint protection, strengthening and adaptive tools, and finger joint pain often settles once bony nodes have formed. Function matters more than the appearance of the X-ray.
Q: What tools make daily tasks easier with arthritic hands?
A: Built-up pen and utensil grips, jar openers, lever-style door handles, electric can openers and lightweight cookware all reduce pinch load. An occupational therapist can review your kitchen, workstation and hobbies and recommend specific adaptations that keep you doing the tasks you care about.
Q: Where can I find hand therapy near me in New Jersey?
A: SportsMed provides hand and occupational therapy at clinics throughout Middlesex, Monmouth and Morris Counties, including Red Bank, Middletown, Edison, Woodbridge, Colonia, Riverdale and Parsippany, as part of a clinic network spanning New Jersey and Connecticut.
