Hallux rigidus, or stiff big toe, is a common degenerative joint disease of the foot. The affected joint is located at the base of the big toe and is composed of two bones: the proximal phalanx (part of the big toe) and the metatarsal bone (long foot bone). Repetitive micro trauma to the big toe is the main cause of this condition. Hallux rigidus is more common in males, athletes, dancers and manual workers.
Regarding symptoms, stiffness and pain on the top of the toe are the hallmark characteristics of this pathology. The big toe develops a big lump on the top which rubs on the shoe wear.
The diagnosis is performed by gathering a medical history, physical examination and requesting imaging studies like X-ray and MRI.
Treatment consist of non-operative and operative.
