Hallux rigidus is osteoarthritis of the joint at the base of the big toe. The joint becomes painful and stiff, often making push-off during walking difficult. The toe is not necessarily crooked; this differs from hallux valgus. Treatment aims to reduce pain and allow practical everyday walking. Whether joint-preserving surgery is appropriate depends, among other things, on remaining cartilage and movement.
A suddenly very red and hot big-toe joint, especially with fever, requires urgent assessment. Increasing redness, discharge or severe new pain after surgery are warning signs.
Causes and risk factors
Previous injuries, repeated loading, joint shape and family factors may play a role. As cartilage changes progress, bony spurs may form and further limit upward movement of the toe. There is not always a single cause. Careful assessment is useful because gout, other joint inflammation and sesamoid problems can also cause big-toe pain and need different treatment.
Typical symptoms
Pain with push-off, walking uphill or shoes pressing on the top of the joint is typical. A bony bump and reduced movement may be noticeable. Some people shift their weight to the outer edge of the foot and develop additional discomfort there. Advanced arthritis can hurt even without much movement. A suddenly very red, hot joint needs prompt examination rather than automatically being labelled arthritis.
Diagnosis
We assess walking, movement, pain location and surrounding structures. It matters whether pain occurs mainly at the end of movement or throughout the range. X-rays, often taken while weight-bearing, show joint space and bony spurs. Further imaging is needed only for specific questions. Treatment also depends on footwear, important activities and the impact on daily life.
Non-surgical treatment
Shoes with enough room, suitable sole stiffness or a rocker sole can reduce painful joint movement. Insoles or targeted stiffening of the forefoot may help depending on the findings. Short-term anti-inflammatory medication may be useful if suitable. Injections are discussed individually, including their limited duration of benefit and risks. Reversal of arthritis or reliable cartilage regrowth is not promised. The aim remains improved capacity for activity.
Surgical options
In selected early or moderate cases, cheilectomy removes bony spurs to create more room for movement. In advanced arthritis, fusion of the big-toe joint is often the more reliable pain-relieving option. Movement in this joint is lost and walking mechanics adapt. Following assessment and consent discussions, we establish which selected foot procedure suits your situation and can be performed at the external surgical centre.
Aftercare and rehabilitation
After surgery, permitted loading depends on the procedure, wound healing and any required bone healing. A special shoe may be needed temporarily. Elevation and wound checks support the early phase. Movement exercises are arranged after joint-preserving surgery; fusion requires different precautions. Swelling can persist longer than skin healing suggests. Work, longer walks and sport resume gradually after checking tolerance.
Common questions
Is hallux rigidus the same as hallux valgus?
No. Hallux rigidus mainly involves arthritis and stiffness; in hallux valgus the big toe deviates sideways.
Can I walk after fusion?
Usually, yes. The aim is less painful push-off. Footwear and individual needs are discussed beforehand.
Is surgery always necessary?
No. Suitable footwear and other non-surgical measures can provide sufficient relief.
Arrange a consultation
We discuss which treatment is suitable for your findings and which procedures are available within our outpatient service during a personal consultation. Outpatient operations take place at an external surgical centre.
