Quick Answer: Hallux rigidus is arthritis in the joint at the base of the big toe. It causes pain and stiffness that get worse when you walk, squat, or push off. Stiff-soled shoes, activity changes, and injections help many people, and surgery can help when those steps are not enough.
If your big toe aches and will not bend the way it used to, you may have hallux rigidus. Hallux rigidus is a form of arthritis in the big toe joint. It often starts slowly. At first, the toe feels a little stiff after a long walk. Over time, a bony bump can form on top of the joint, and even shoes can start to hurt.
Fall is a busy walking season in Southern California. Cooler mornings bring more people out on neighborhood walks in Pomona and Claremont, and the holidays mean long days on your feet and dressier shoes. These are often the moments when a stiff big toe becomes hard to ignore. The good news is that hallux rigidus is very treatable, especially when it is caught early.
What Is Hallux Rigidus?
Hallux rigidus is arthritis of the first metatarsophalangeal joint, often called the MTP joint. This is where the big toe meets the foot. The American Orthopaedic Foot and Ankle Society (AOFAS) notes that this joint is the most common place for arthritis to develop in the foot.
Your big toe bends upward every time you take a step. That motion lets your foot roll forward and push off the ground. When the smooth cartilage in the joint wears down, the bones start to rub, and the body may grow bone spurs along the top of the joint. The spurs block the toe from bending, which is why the toe feels "stuck."
Doctors sometimes call the early stage hallux limitus, which means the toe has limited motion. Hallux rigidus is the later stage, when the toe is very stiff. You can learn more about this condition on our hallux rigidus (stiff big toe) page.
Common Symptoms
Pain and stiffness in the big toe joint are the main signs. Many people also notice a bump on top of the joint that rubs against shoes. Pain is often worse when you walk uphill, climb stairs, squat, or wear high heels. Some people start walking on the outside of the foot to protect the toe, which can lead to pain in other parts of the foot, knee, or hip.
What Causes a Stiff Big Toe?
There is usually not one single cause. Several things can raise your risk:
Wear and tear over time is a common factor. The joint takes force with every step, so years of walking, running, and standing add up. Hallux rigidus most often shows up in adults between 30 and 60, according to the American Academy of Orthopaedic Surgeons (AAOS).
Past injury is another cause. A stubbed toe, a sprain such as turf toe, or a broken bone near the joint can damage the cartilage and lead to arthritis years later.
Foot shape also matters. A long first metatarsal bone or a flat foot can put extra strain on the big toe joint. Hallux rigidus can also run in families, partly because foot shape is inherited.
Other health conditions can play a role too. Inflammatory arthritis, such as rheumatoid arthritis, and gout can both affect the big toe joint. That is one reason a proper exam matters. Big toe pain is not always hallux rigidus, and the right treatment depends on the cause.
How Is Hallux Rigidus Diagnosed?
A foot and ankle specialist will ask about your symptoms and look at how your big toe moves. They will check for a bone spur, swelling, and pain when the toe bends. They may also watch you walk.
X-rays are the main test. They show how much joint space is left, where bone spurs have formed, and how far the arthritis has progressed. This helps your doctor decide which treatments make the most sense for you. Big toe arthritis is one part of a larger group of conditions covered on our foot and ankle arthritis page.
When to See a Specialist
Make an appointment if big toe pain lasts more than a few weeks, if you see a bump growing on top of the joint, if the toe is getting stiffer, or if you are changing the way you walk. You should also be seen if the joint becomes red, hot, and very painful overnight, since that can be a sign of gout or infection.
Hallux Rigidus Treatment Options
Most people start with nonsurgical treatment. The goal is to reduce pain and keep you moving.
Shoe Changes and Inserts
Shoes with a stiff sole and a roomy toe box limit how much the big toe has to bend. A rocker-bottom sole helps your foot roll forward without forcing the joint. Custom or over-the-counter inserts with a stiff plate under the big toe can also help. Avoid high heels and thin, flexible flats, especially during long holiday events.
Activity Changes and Medicine
Swapping high-impact activities for lower-impact ones, such as cycling or swimming, can calm a sore joint. Ice after activity may ease swelling. Over-the-counter anti-inflammatory medicine may help some people, but check with your doctor first, especially if you have stomach, kidney, or heart concerns.
Injections
A steroid injection into the joint can reduce pain and inflammation for a period of time. Injections do not cure arthritis, but they can give relief and make it easier to stay active.
Simple Exercises
Gentle range of motion exercises can help keep the joint moving. Try slowly bending the big toe up and down with your hand, or picking up a small towel with your toes. Stop if an exercise causes sharp pain. A physical therapist can suggest a program that fits your stage of arthritis.
Surgery
Surgery may be an option when pain keeps you from daily activities and other treatments have not worked. The right surgery depends on how much arthritis is present.
A cheilectomy removes the bone spur and part of the damaged bone. It is often used for mild to moderate arthritis and can improve motion and pain. For more severe arthritis, a fusion (arthrodesis) joins the bones so the joint no longer moves. Fusion is very good at relieving pain, and most people can still walk normally and wear regular shoes afterward. Some patients may be candidates for other joint procedures. Your surgeon will explain the pros and cons of each.
Recovery depends on the procedure. After a cheilectomy, many people walk in a special shoe within days. A fusion takes longer to heal, often a few months, and you may need to limit weight on the foot at first.

Conclusion
Hallux rigidus is a common cause of big toe pain and stiffness, and it tends to get worse slowly over time. Early care, the right shoes, and smart activity choices can keep many people comfortable for years. When those steps are not enough, surgery can relieve pain and help you walk with confidence again. Patients from Pomona, Claremont, La Verne, and across the Inland Empire can be seen at our Pomona office.
