The horseshoe varus foot disease is caused by what reason?
in most cases, the horseshoe varus foot reason is unclear, but it is in some families. Studies have reported that the incidence of congenital horseshoe varus foot is 1/800 or 1/1000. In some water chestnut varus foot is more common in the crowd. Cause the horseshoe varus foot risk factors as follows:
1. Genetic factors,
with family history of the disease is a genetic relationship, such as Wynne - Pavis reports such as: the proportion of patients with a family history of 2. 9%; The incidence of other identical twin is higher than double egg twins compared with 33:3. Although heredity is an important factor, but it is not sure recessive or dominant sex law of genetic inheritance.
2。 Embryo factors
Bohm believe that embryos within 3 months, the foot in a horseshoe varus three original deformed state, namely prolapse, adduction and supination ( Varus) 。 Since 4 months, the foot is in neutral rotation, metatarsus slightly adduction, also before along the long axis rotation, foot position close to normal. Any developmental disorders will keep the foot in the early embryo deformity.
3。 Intrauterine factor
in intrauterine fetal position, foot pressure, for a long time in the foot adduction, hang in the heel, and ankle. Accordingly crus and medial muscle shortening, thickening of the inside of the joint capsule, make feet further deformities.
4。 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. Someone to prove in the critical moment of the development of limbs in hypoxia may lead to water chestnut. Stewart found that in many patients from Japan, because have the habit of sitting on varus foot pedal, particularly high incidence.
it is naturally asked why they will produce equinus varus. Many parents want to know what they did cause the horseshoe varus foot, or is there any way to prevent the horseshoe varus foot. Although these risk factors make people are more likely to develop the horseshoe varus foot, but it cannot be predicted or prevented. It's nobody's fault, but treatment can help your child. If you're worried about regeneration a child will develop the horseshoe varus foot, please keep in mind that a second child from the horseshoe varus foot probability as high as 96%.
