The main and the most common type of flat feet, both in children and in adults, is static flat feet, the main causes of which are weak muscle tone (in children), excessive fatigue due to prolonged standing on feet, excess weight, professional type of activity, features anatomical structure, frequent static and dynamic loads (in women during pregnancy), abuse of narrow high-heeled shoes, etc.

Flat feet associated with trauma are less common. This can be a fracture of the bones of the foot, ankles, or even a slight sprain of the ligaments.

Usually, after the treatment of the trauma, the complex system of the ligamentous apparatus of the foot and the ankle joint begins to work with its own biomechanics, which can lead to progressive deformation of the limb, therefore, the use of orthopedic aids and devices is a justified and necessary part of post-traumatic rehabilitation measures.

With longitudinal flat feet, the longitudinal arch of the foot is flattened, it often occurs in childhood, even at the stage of foot formation.

Transverse flatfoot is characterized by flattening of the front part of the foot.

It is very important to define the degree of flat foot because the severity of the problem and the necessary measures to be taken depend on it.
