Understanding Hallux Rigidus vs Bunion Deformity
Many patients assume that a painful lump near the big toe is a bunion. However, in many cases, this may actually be big toe arthritis, also known as Hallux rigidus.
Understanding the difference between these two conditions is critical because the treatment approach is completely different.
What Is Hallux Rigidus?
Hallux rigidus is a form of arthritis affecting the first metatarsophalangeal (MTP) joint at the base of the big toe.
It develops gradually and leads to:
- Joint stiffness
- Pain during walking or activity
- Reduced range of motion
- A bony lump on top of the joint
This top-side bone growth is often mistaken for a bunion, which appears on the inner side of the foot.
Not Sure If It’s a Bunion or Arthritis?
If you’ve noticed a lump or stiffness in your big toe, don’t guess.

Hallux Rigidus vs Bunion: Key Differences
Patients often confuse arthritis with a bunion, but they are very different conditions.
Hallux Rigidus:
- Pain inside the joint
- Stiffness and limited movement
- Bone growth on top of the joint
Bunion (Hallux Valgus):
- A bony bump on the inner side of the foot
- Big toe leaning towards other toes
- Usually maintains joint movement (early stages)

What Causes a Stiff Big Toe Joint?
There is usually a combination of factors:
- Genetics
- Previous trauma (e.g. stubbing your toe)
- Repetitive stress (sports or activity)
- Tight or restrictive footwear
- Abnormal foot mechanics
Over time, this leads to cartilage damage and arthritis.
How Is Hallux Rigidus Diagnosed?
Diagnosis involves:
- Clinical examination
- X-rays to assess joint damage
- MRI scans (in early cases where X-rays are inconclusive)
At London Foot and Ankle Surgery, patients benefit from a full consultant-led assessment and access to advanced imaging where needed.

Non-Surgical Treatment Options
In early stages, symptoms can often be managed without surgery:
- Wider, stiff-soled footwear
- Custom orthotics (motion control insoles)
- Activity modification
- Steroid injections (temporary relief)

Minimally Invasive Surgery for Hallux Rigidus
When symptoms persist, surgery may be required.
Cheilectomy (Bone Spur Removal)
For early to moderate arthritis, a minimally invasive cheilectomy may be performed:
- Small incision (~4mm)
- Removal of bone spurs
- Joint preserved
- Faster recovery
Recovery timeline:
- Immediate mobilisation
- Rest 3–5 days
- Healing within ~10 days
- Quick return to activity

Minimally Invasive vs Open Surgery
Minimally invasive surgery offers:
- Less tissue trauma
- Smaller scars
- Faster recovery
- Lower risk of stiffness
Open surgery involves larger incisions and longer downtime.
Advanced Arthritis: Fusion Surgery
In severe cases, big toe joint fusion (arthrodesis) is the gold standard.
- Eliminates pain
- Improves foot stability
- Suitable for active patients
Minimally invasive fusion is increasingly used with strong outcomes.

Risks of Treatment
Cheilectomy:
- Symptoms may return over time
- Infection (rare)
- Delayed healing
Fusion:
- ~5% risk of non-union
- Possible hardware removal
All risks are assessed individually during consultation.
Can the Big Toe Joint Be Replaced?
Joint replacement is available, but typically for lower-activity patients.
- Implants may wear out after ~10 years
- Not ideal for high-impact lifestyles
When Should You See a Specialist?
If you’re experiencing:
- A painful lump near the big toe
- Stiffness or reduced movement
- Difficulty walking or exercising
…it’s time to get it checked properly.
