| Grade | Coughlin-Shurnas Classification | ROM (Dorsiflexion) | X-ray Findings | Symptoms |
|---|---|---|---|---|
| Grade 0 | Stiffness only; no radiographic changes | 40–60° (normal or mildly limited) | Normal | Morning stiffness; no pain at extremes |
| Grade 1 | Mild | 30–40° | Dorsal osteophyte; minimal joint space narrowing | Mild pain at extremes; dorsal bump palpable |

| Treatment | Grade Indication | Mechanism | Success Rate | Preserves Motion? |
|---|---|---|---|---|
| Stiff-soled / Carbon Fiber Insole | Grade 1–3 (conservative) | Reduces MTPJ dorsiflexion demand during gait | 50–65% symptom control | Yes — motion not affected |

| Cheilectomy (osteophyte removal) | Grade 1–2; functional limitation from dorsal impingement | Removes dorsal 25–30% of MT head + osteophytes; restores dorsiflexion arc | 70–80% good-excellent at 5–10 years; Grade 1–2 best outcomes | Yes — increases ROM 10–20° |
| Moberg Proximal Phalangeal Osteotomy | Grade 2–3; adjunct to cheilectomy in high-demand patient | Dorsiflexion osteotomy of base of proximal phalanx shifts ROM into functional range | 80–85% when combined with cheilectomy | Yes — redistributes ROM |
| MTPJ Arthrodesis (fusion) | Grade 3–4; failed cheilectomy; high-demand patient | Fuses first MTPJ in 15° dorsiflexion + 10–15° valgus; eliminates arthritic pain | 85–95% pain relief; gold standard | No — permanently eliminated |
| MTPJ Arthroplasty (implant) | Grade 3–4; elderly low-demand patient; motion preservation desired | Resurfacing or total implant replaces destroyed cartilage | 70–80%; less durable than arthrodesis at 10+ years | Yes — partial ROM preserved |

Quick Answer:
Quick Answer: Hallux rigidus is arthritis of the first metatarsophalangeal (MTP) joint — progressive loss of dorsiflexion (upward motion) of the big toe, causing pain with walking and push-off. Grade 1-2: cheilectomy (removal of dorsal bone spurs) restores motion and provides lasting relief. Grade 3-4 (severe): first MTP fusion (arthrodesis) eliminates the painful joint entirely — highly durable, the gold standard for severe hallux rigidus. Implant arthroplasty is an alternative to fusion with variable long-term outcomes.
Hallux rigidus — arthritis of the first metatarsophalangeal joint causing progressive stiffness and loss of big toe dorsiflexion — is the most common form of arthritis in the foot, affecting up to 2% of adults over 50. The condition impairs the normal “toe-off” phase of gait, causing pain, altered walking mechanics, and compensatory dysfunction throughout the lower extremity. At Balance Foot & Ankle PLLC, Dr. Tom Biernacki provides comprehensive hallux rigidus management from conservative care to definitive surgical correction matched to the patient’s severity, activity level, and goals.
Grading and Treatment Selection
Grade 1 (Mild): Mild loss of dorsiflexion (>50° remaining), minimal articular cartilage loss, dorsal osteophytes beginning. Conservative management: stiff-soled footwear with rocker bottom, cortisone injection, activity modification. If surgery indicated: cheilectomy alone. Grade 2-3 (Moderate-Severe): Progressive joint space narrowing, dorsal and lateral osteophyte formation, 25-50° of remaining dorsiflexion, significant pain with activity. Cheilectomy may be combined with Moberg osteotomy (dorsal closing wedge osteotomy of the proximal phalanx) to improve functional dorsiflexion arc. Grade 4 (End-Stage): Global cartilage loss, bone-on-bone arthritis, severe motion restriction. Surgical options: first MTP fusion (arthrodesis) or implant arthroplasty. Fusion is the gold standard for reliable, durable pain relief.
Cheilectomy
Cheilectomy removes the dorsal osteophytes (bone spurs) that block toe dorsiflexion — restoring motion, reducing impingement pain, and providing excellent outcomes in Grade 1-2 disease. 25-30% of the dorsal metatarsal head is resected. Recovery: immediate weightbearing in a surgical shoe, regular footwear at 4-6 weeks. Excellent patient satisfaction in properly selected patients. Recurrence of osteophytes is possible over years — the underlying arthritic process continues, but cheilectomy buys substantial functional time before fusion is needed.
First MTP Fusion
First MTP fusion for severe hallux rigidus eliminates the painful joint by achieving bone-to-bone healing at approximately 15-20° of dorsiflexion — the optimal functional position for normal toe-off gait. Internal fixation with a dorsal plate and screw provides rigid fixation. Union rates exceed 95%. Recovery: non-weightbearing 6 weeks, walking boot 6-8 weeks, regular footwear at 3-4 months. Excellent long-term outcomes — multiple studies demonstrate high satisfaction and durable pain relief at 10+ year follow-up.

✅ Pros / Benefits
- Cheilectomy provides excellent relief in Grade 1-2 hallux rigidus with quick recovery
- First MTP fusion has 95%+ union rate and exceptional long-term pain control
- Fusion position optimized for toe-off gait — most patients walk with minimal visible gait change
- Moberg osteotomy combined with cheilectomy extends functional range in moderate disease
❌ Cons / Risks
- First MTP fusion permanently eliminates joint motion — no running or high-heeled shoes after fusion
- Non-weightbearing phase (6 weeks) is required for fusion healing
- Implant arthroplasty carries revision risk — fusion is more durable for most patients
Dr. Tom Biernacki’s Recommendation
Hallux rigidus fusion is a procedure I’m asked about frequently because patients fear losing motion in their big toe. My honest answer: after fusion, the functional change is less than they expect. The toe is fused in the optimal walking position — most patients barely notice a gait change, and they’ve traded years of pain with every step for a comfortable, stable joint. A patient who couldn’t walk their dog now can. The functional trade-off in Grade 4 hallux rigidus is firmly in favor of fusion.

Frequently Asked Questions
What does hallux rigidus feel like?
Hallux rigidus presents as stiffness and pain at the base of the big toe — particularly with activities requiring upward toe bending (walking uphill, climbing stairs, squatting, running). Early hallux rigidus: pain only at the extremes of motion with a noticeable dorsal bony bump (osteophyte). Advanced hallux rigidus: pain throughout push-off with any walking, inability to wear heels, and visible toe stiffness. The hallmark: reduced big toe dorsiflexion on examination — less than 20-30° in advanced cases.
Can hallux rigidus be treated without surgery?
Yes — mild-to-moderate hallux rigidus often responds well to conservative treatment for years. Rocker-bottom footwear dramatically reduces first MTP dorsiflexion requirement during gait. Stiff-soled dress shoes with a low heel. Cortisone injection for acute flares. Activity modification — reducing hill running, high-heel wearing, and squatting. Custom orthotics with Morton’s extension (rigid extension under the hallux) further limits MTP dorsiflexion. Surgery is considered when conservative measures no longer provide adequate quality of life.
What is cheilectomy and how long does it last?
Cheilectomy is surgical removal of the dorsal bone spurs (osteophytes) at the first MTP joint that block big toe dorsiflexion — combined with resection of 25-30% of the dorsal metatarsal head. The procedure is most effective for Grade 1-2 hallux rigidus with preserved articular cartilage. Expected duration: 7-10+ years of improved function in properly selected patients. The underlying arthritic process continues — eventually, progression to Grade 4 may require fusion. Cheilectomy does not prevent future fusion if needed.
What happens to my foot after first MTP fusion?
After first MTP fusion: the joint is permanently stiff — you will not be able to dorsiflex the big toe, but this is the position it was fused in (15-20° of extension). Walking is normal — the rigid toe-off in the fused position is compatible with comfortable gait. Running is possible but different — the forefoot rocker is absent. High-heeled shoes over 1-inch heel height are not comfortable after fusion. Activities most affected: yoga, kneeling, squatting. Activities least affected: walking, cycling, swimming. Most patients are surprised by how well they walk after fusion.
