Hallux rigidus/ Hallux limitus

1. [noun] hallux rigidus literally means "stiff big toe," which is the main symptom of the disorder. Hallux rigidus is a form of degenerative arthritis, which can cause pain and stiffness in the metatarsophalangeal joint (the joint where your big toe—the hallux—joins your foot). Because hallux rigidus is a progressive condition (gets worse over time), the toe's motion decreases as time goes on, making walking or even standing painful. The pain and stiffness may get worse in cold, damp weather, and the joint may become swollen and inflamed. A bump, like a bunion or callus, often develops on the top of the foot and makes wearing shoes difficult. Hallux rigidus is the second most common disorder of the big toe, after hallux valgus (bunions). Hallux rigidus occurs in adolescents and adults and is most common in people between the ages of 30 and 60.
