As a parent, have you ever observed your child’s legs and walking gait? After observation, you may find that your child’s legs are not straight together and he or she walks with an inward or outward figure-of-eight gait, which is often referred to as inversion or valgus knee. This is often referred to as inversion or ectropion of the knee. Inversion of the knee, also known as “O” shaped leg, is mainly manifested by outward bending of the lower limbs, wide distance between the knees, swaying walking, and inward bias of the toes. Knee valgus is also known as “X” shaped leg, or “K” shaped leg if it is unilateral, mainly manifesting as awkward walking, double knees colliding with each other when walking, easy to fall down, toes deviating inward; in lying position, lower limbs straight, patella facing upward, when both knees are together, the distance between the bilateral inner ankles The greater the distance, the heavier the inversion. Knee inversion and knee valgus are two common angular deformities of the lower extremities in children, which affect children’s participation in sports and normal walking, and sometimes cause pain in the lower extremities, which is often referred to as leg pain by children.
There are two types of valgus and valgus knee depending on the cause: developmental valgus and valgus knee, and pathological valgus and valgus knee. The so-called developmental knee inversion and knee valgus are natural phenomena during the growth and development of children. This is a physiological knee valgus and does not usually require treatment. Pathological valgus and valgus knees are caused by abnormal bone metabolism, endocrine disorders or trauma, and cannot be corrected with growth, such as rickets. Pathological inversions and ectropion require treatment for the cause and sometimes surgery for the residual deformity.
There are three types of developmental inversions and ectropion depending on the severity: mild with a knee and ankle spacing of 75px or less, moderate with 3-250px, and severe with 250px or more. Generally speaking, mild cases of knee entropion and knee valgus do not require treatment, while moderate cases of knee entropion or knee valgus deformity require treatment, and the following treatments are commonly used: 1. Manipulation correction: for younger children with mild degrees of entropion and rickets that have not yet healed. The upper and lower extremities of the affected limbs are fixed, and the most obvious deformity is gently pressed 20-30 times with moderate pressure, avoiding violence, 3-4 times a day, continuously, without interruption.
2, brace treatment: the three-point correction theory of the brace is used for treatment, according to the patient’s specific condition customized special orthopedic brace, and insist on wearing at night. Note the need for specialized brace maker, currently on the market more braces, the quality and effect varies greatly.
2, padded sole correction method: the sole of the medial or lateral padded 0, 8-1 cm, knee inversion padded sole of the lateral half, knee valgus padded sole of the medial half, to change the line of negative gravity when walking, so that the deformity gradually corrected.
3.Surgical correction method: Severe knee inversion and knee valgus, as well as pathological knee inversion and knee valgus needing surgical treatment, can use “8” plate semi-epiphyseal block surgery, the method uses the growth and development potential unique to children to regulate and correct the lower limb into the angle deformity. The method is an advanced concept, a minimally invasive procedure, and has good surgical results. Compared to traditional osteotomy, the procedure is less invasive, less painful for the child, faster recovery, and less risky, but the method is slower to work because it depends on the child’s growth potential to regulate. Only traditional osteotomy can be used to treat children who are mature or near mature.
