We advise you to consult and treat the flat foot before the onset of complications. Achilles tendonitis, stiffness, joint limitations.Tendon pain and instability (fibular dislocation).Ankle joint instability or (cuneometatarsal).Pain under the forefoot or metatarsalgia.Plantar fasciitis or fasciitis which may be associated with a heel spur.An evolved flat foot can lead to complications and related pathologies such as: In the absence of suitable treatment, the spontaneous evolution of the foot is the aggravation of deformities and pain. This classification is important for the surgeon because it directly informs the surgeries and the procedures to be performed. Finally, in the most advanced stage, we find ankle arthritis. In the more advanced clinical stages, the foot is deformed but it is no longer flexible : we speak of a fixed or non-reducible flat foot valgus. It can be painful and disabling on a daily basis, both feet are often affected. In the first stages of development, the flat foot is flexible : we speak of reducible or flexible foot (stage 1 and 2). There are several clinical stages of flat feet. Clinically, abnormalities of the hindfoot, midfoot and forefoot are observed in flexible flatfoot. We classically observe in the flat foot valgus : a valgus of the rear foot (heel which goes outwards), a collapse of the medial arch secondary to a failure of the posterior hamstring and the spring ligament as well as a supination compensating forefoot. The flat foot is the loss of the propeller and conversely in the hollow foot, the propeller is too twisted. Usually, the foot has the shape of a propeller. It mainly affects women between 40 and 60 years old.

The arch of the foot is formed by the architecture of the bone pieces, by ligament and muscle structures that fight against crushing under the weight of the body. Flatfoot is a biomechanical problem characterized by the sagging of the internal arch of the foot and the decrease in the arch of the foot (loss of curvature or arch of the foot).
