There are congenital dislocations - which developed during the fetal life of the fetus, and acquired - as a result of trauma (traumatic dislocation) or a pathological process in the joint area (pathological dislocation).
The vast majority of congenital dislocations occur in the hip joint on one or, more often, on both sides. As a rule, they are noticed when the child begins to walk. Lameness, looseness of the joint, soreness in it, shortening of the leg are noted. For bilateral dislocation is characterized by a gait trailing ("duck"). The diagnosis is specified by x-ray.
