[Hallux Rigidus: first metatarsophalangeal arthrosis Symptoms and current treatments].

Metatarsophalangeal arthritis of the first ray of the foot, also known as hallux rigidus, is an invalidating cause of walking that is still underestimated. It is associated to a local deformation of the first ray with a limitation of the dorsal mobilization of the joint, affecting thus the propulsion of the foot. Several stages of the disease exist, and symptoms as well as the treatment will depend on the moment of the consultation. In this paper, we present the different clinical pictures and adapted treatments according to the stage of the disease, and we share our results of a new modality of surgery that conserves the articular mobility of the joint.
