A 55-year-old man presents with progressive pain and stiffness of the first metatarsophalangeal joint. Examination shows limited dorsiflexion, dorsal osteophyte formation, and pain with passive extension. The most likely diagnosis is:
- A Gouty arthritis
- B Hallux rigidus ✓
- C Hallux valgus
- D Sesamoiditis
Correct answer: B. Hallux rigidus
Explanation
Hallux rigidus is degenerative arthritis of the first MTP joint presenting with pain, stiffness, limited dorsiflexion, and a dorsal osteophyte. The condition is distinguished from hallux valgus by the preserved or minimal valgus alignment and the predominant stiffness. Gout presents acutely with redness and warmth. Sesamoiditis causes plantar pain beneath the metatarsal head, not dorsal osteophyte formation.
