Congenital equinus varus harm you'd like to know, to understand what factors in the first place

by:Ideastep     2020-10-18

congenital equinus varus is a common congenital malformations, its incidence is 1/1000, the boy see more, slightly more than bilateral unilateral.

it's not difficult to diagnosis, appearance is very typical, can be found that birth of forefoot adduction, in turn, with varus deformity, water chestnuts and ankle bone tibia are within a merger. With the growth and development, with lateral crus.

equinus diagnosis

equinus generally occurs at birth or infantile period, after the patient is sick, will largely affect the patient's health. Generally has the following characteristics:

1, with one side or double parapodum department after the baby was born in plantar flexion deformity.

2, tibial internal rotation; The plantar passive correction can't back out.

3 walking, standing plantar outer load, serious when foot back edge weight, weight bearing area produce slippery bursa phlogistic and callus.

4, unilateral deformity, walking with a limp, bilateral deformity, swaying walk.

5, X-ray radiography: from the longitudinal axis of the first metatarsal bone and cross Angle is greater than 15 & deg; , heel and plantar surface of longitudinal axis Angle is less than 30 & deg; 。

congenital horseshoe varus foot is also a kind of common foot deformity, can find general child was born, if not corrected in time, will bring inconvenience to the whole life to a child. So, we can understand the influence factors of affect the horseshoe varus foot as much as possible to avoid the occurrence of the disease. So, what are the influence factors of congenital horseshoe varus foot?

what are the influence factors of congenital horseshoe varus foot: genetic factors, congenital horseshoe varus foot is also a kind of common foot deformity, can find general child was born, if not corrected in time, will bring inconvenience to the whole life to a child. So, we can understand the influence factors of affect the horseshoe varus foot as much as possible to avoid the occurrence of the disease. So, what are the influence factors of congenital horseshoe varus foot? First, genetic factors: 1, congenital horseshoe varus foot often with family history of a genetic relationship, such as Wynne - Pavis reports such as: the proportion of patients with a family history of 2. 9%; 2, in addition of identical twin of incidence of a disease is higher than double egg twins compared with 33:3. 3, although genetic is an important factor, but it is not sure recessive or dominant sex law of genetic inheritance.

what are the influence factors of congenital horseshoe varus foot: embryo factors in addition to the common genetic factors, the influence factors of congenital horseshoe varus foot and embryo factors, because the cause of the disease has not been in the medical profession, but many scientists put forward a hypothesis, so, here provide factors are established by medical hypothesis. Embryo factors: 1, Bohm think, embryo within 3 months, the foot in a horseshoe varus three original deformed state, namely prolapse, adduction and supination ( Varus) 。 2, since 4 months, the foot is in neutral rotation, metatarsus slightly adduction, also before along the long axis rotation, foot position close to normal. 3, any developmental disorders will keep the foot in the early embryo deformity.

what are the influence factors of congenital horseshoe varus foot: intrauterine factors in addition to that, in the womb of intrauterine factors also influence of congenital horseshoe varus foot of one of the elements. Intrauterine factors: 1, the fetus intrauterine postures, foot pressure, for a long time in the foot adduction, hang in the heel, and ankle. 2, accordingly crus and medial muscle shortening, medial thickening of joint capsule, make feet further deformities. [ The horseshoe varus foot causes of congenital horseshoe varus foot is caused by genetic]

what are the influence factors of congenital horseshoe varus foot: environmental factors, many scholars study found that the disease is associated with environmental factors, such as Duraswami insulin injections to cause water chestnut inside a developing embryo varus deformity. Concrete analysis: 1, someone proved that in the critical moment of the development of body in hypoxia may lead to water chestnut. 2, Stewart, found in many patients from Japan, because have the habit of sitting on varus foot pedal, particularly high incidence.

congenital horseshoe varus foot treatment: correction method 1, by technique modification, plaster fixed orthodontic treatment failure of the child, or a missed opportunity to orthodontic treatment of children, can be treated by surgery. Three to 15 years old of children, can use soft tissue release surgery. 2, after 15 years old of children, correction, soft tissue release surgery can not achieve the desired purpose, or severe strephenopodia prolapse did not treated children, can pass three joint fusion surgery, surgery with distance, plaster fixation to foot all the time so far away from the boat, with dice three joint fusion.
