congenital hallux varus
Introduction
Introduction to congenital hallux varus Congenital, varus (congenitalhalluxvarus), as opposed to eversion, is characterized by the fact that the toe is angled inward at the metatarsophalangeal joint, resulting in the separation of the toe from the second toe, accompanied by an increase in the angle between the first and second metatarsal . Most scholars believe that the deformity occurs in the uterus, and two primordia of the big toe appear on one foot, that is, an auxiliary big toe occurs on the inner side of the original big toe, which is dysplastic and combined with fibrous tissue to form a The tensioned bow-like contracture tissue gradually pulls the original big toe into a varus deformity. The conservative treatment of this disease is not effective, and surgery is generally required. Different procedures, such as Farmer surgery and McElvenny surgery, are performed depending on the degree of toe varus. If the osteoarthritis has occurred in the metatarsophalangeal joint, McKeever surgery can be used; for severe cases, the interception should be considered. basic knowledge The proportion of illness: 0.02% Susceptible people: children Mode of infection: non-infectious Complications: abnormal gait
Cause
Congenital hallux inversion
Causes:
Most scholars believe that the deformity occurs in the uterus, two on one foot, the toe primordial, that is, on the inner side of the original toe, a vice, toe, this vice, toe dysplasia, combined with fibrous tissue, forming a The tensioned bow-stringed contracture tissue gradually pulls the original, and the toe becomes a varus deformity.
Prevention
Congenital thumb varus prevention
Premarital examination: the first line of defense to prevent the birth of congenital malformations. Most congenital malformations are generally incurable once they are born, so it is very important to prevent the birth of a child.
Complication
Congenital hallux complication Complications gait abnormalities
The inner edge of the inverted toe is easily squeezed in the shoe, and there are symptoms such as swelling and pain. In severe cases, it is difficult to wear shoes and abnormal gait. Other diseases and symptoms will not be complicated.
Symptom
Congenital hallux varus symptoms Common symptoms Thumb unexplained pain Pain abnormalities can not stretch the thumb and foot swelling and tenderness
The inner edge of the inverted toe is easily squeezed in the shoe, and there are swelling, pain and other discomfort symptoms. In severe cases, it is difficult to wear shoes, and the gait is abnormal. According to the medical history, clinical manifestations and X-ray films, the diagnosis can be made.
Examine
Congenital thumb varus examination
X-ray film shows: 1st, the joint is angularly deformed to the inside, and the toe is separated from the second toe. Generally, the first and second metatarsal angles are increased, and the first metatarsal is short and thick.
Diagnosis
Diagnosis of congenital hallux varus
Congenital, varus should be caused by acquired factors, varus identification:
1. Trauma, muscle imbalance (weak muscle strength, strong muscle strength) or valgus deformity surgery overcorrection,
2. Various first toe infectious or non-infectious (aseptic) arthritis, such as septic arthritis, rheumatoid arthritis, etc., due to joint destruction, toe varus.
