Hallux
Hallux
Hallux (pronounced: /ˈhælʌks/), is the medical term for the big toe on the human foot. The term is derived from the Latin word 'hallus' which means 'big toe'.
Anatomy
The hallux is the most interior (or medial) digit of the foot and plays a crucial role in maintaining balance, walking, and running. It consists of two phalanges, the proximal phalanx and the distal phalanx, which are the bone segments of the toe. The hallux is connected to the first metatarsal bone via the metatarsophalangeal joint.
