Hallux Rigidus and Big Toe Fusion
Overview
Hallux rigidus is osteoarthritis of the joint at the base of the big toe. It can cause pain, stiffness and a bony prominence on top of the joint during walking and push-off. Treatment starts with footwear, activity adjustment and selected medicines. Cheilectomy may help selected earlier disease by removing impinging bone. Fusion is an established option for advanced painful arthritis, but it permanently removes movement from that joint.
Symptoms
- Pain at the base of the big toe during push-off, hills, stairs, lunges or running.
- Stiffness and reduced ability to bend the toe upwards.
- A bony prominence on top of the joint that rubs in shoes.
- Swelling, grinding or pain through the middle range of motion in more advanced disease.
- Altered walking and transfer of load to the outer forefoot.
assessment
Examination assesses where pain is felt, how far the toe moves, whether movement grinds or hurts, alignment, the small sesamoid bones beneath the joint and the rest of the foot. Weight-bearing X-rays show joint-space loss, bone spurs, cysts and alignment. The amount of X-ray change does not by itself determine treatment.
Pain only at the end of upward movement may behave differently from pain throughout the whole arc of motion. This helps distinguish selected joint-preserving options from fusion.
Other causes of pain at the big-toe joint include gout, inflammatory arthritis, problems affecting the sesamoid bones, injury to cartilage and the underlying bone, stress injury and hallux valgus. Blood tests or advanced imaging are used selectively.
Non-surgical treatment
- Shoes with a wide toe box and a stiff or rocker sole to reduce painful joint bending.
- A carbon or rigid insert, where tolerated.
- Modify activities that repeatedly bend the big toe far upwards.
- Pain-relieving or anti-inflammatory medicine when medically appropriate.
- A corticosteroid (cortisone) injection may provide temporary relief in selected cases but does not reverse arthritis. Repeated injections require individual review.
Joint-preserving surgery
For earlier disease with pain mainly from a dorsal spur and reasonable remaining joint surface, cheilectomy may remove the impinging bone and improve upward movement. In selected cases, a small bone cut in the big toe can be added to improve clearance.
Cheilectomy does not remove arthritis from the whole joint. Pain may persist or arthritis may progress, and later fusion can still be required.
Big-toe joint fusion
Fusion is an established option for severe arthritis, major stiffness, deformity, instability or failed previous surgery. Damaged cartilage is removed, the toe is positioned for walking and footwear, and the bones are fixed with screws and/or a plate while they unite.
Fusion permanently removes movement at the arthritic joint. Most walking and many activities remain possible, but footwear with very high heels and activities requiring substantial big-toe bend may be limited. Position is important because a toe fused too high, low or rotated can cause shoe and pressure problems.
Recovery
A postoperative shoe or Moonboot is used, with weight-bearing based on fixation, bone quality and the individual plan. Elevation helps control early swelling. X-rays are used to assess union before unrestricted loading and higher-impact activity.
Swelling can remain for months. Return to driving and work depends on the side, footwear, walking safety, medication and work demands.
Risks and limitations
- Infection, wound problems, numbness or scar sensitivity.
- Delayed or failed bone healing, sometimes requiring further surgery.
- Malposition of the toe or fixation irritation.
- Persistent pain, transfer pain or adjacent-joint symptoms.
- Stiffness after joint-preserving surgery or progression of arthritis.
- Blood clots and anaesthetic complications.
Frequently asked questions
Is hallux rigidus the same as a bunion?
No. Hallux rigidus is arthritis and stiffness of the big-toe joint. Hallux valgus is an alignment deformity, although both can coexist.
Will fusion make me walk with a limp?
A well-positioned fusion usually allows comfortable walking, but the toe joint will no longer bend and some footwear or high-impact activities may be limited.
Can the joint be replaced instead of fused?
Joint-replacement implants exist, but suitability, bone preservation and durability vary. Fusion remains an established option for advanced disease. The trade-offs can be discussed for your individual circumstances.
Can arthritis return after fusion?
The fused joint itself no longer moves or develops joint pain, but failure of bone healing, irritation from the fixation or symptoms in nearby joints can occur.
Is cheilectomy suitable for severe arthritis?
Usually not when pain occurs throughout motion and joint space is substantially lost. Fusion is often more predictable in advanced disease.
