Description

Corrective device for pediatric developmental dysplasia of the hip

technical field

The utility model relates to the technical field of medical care products, in particular to a device for correcting developmental dysplasia of the hip joint for children.

Background technique

Hip dysplasia is a collective term for congenital or developmental structural abnormalities of the hip joint in infancy and childhood, including acetabular dysplasia, dislocation, and subluxation. Early symptoms include asymmetric hip lines, asymmetric thigh lines and unequal lengths of lower limbs, etc. It is generally believed that the incidence of the disease is 0.1% to 0.3%, and there is a lack of comprehensive and authoritative statistical data in China. Girls were mostly girls, with a male to female ratio of 1:6, and 20% of the children had a family history. The etiology is unclear, but may be related to breech delivery, joint laxity, and family history.

For developmental dysplasia of the hip, early diagnosis and early treatment are needed, and the older the age, the worse the curative effect. For infants and young children, conservative treatment is mainly used for closed reduction. For example, infants and young children are given special stockings, Pavlik harnesses, or plaster racks to open and fix their thighs, so that their thighs can be fixed. In the abducted position to force the femoral head into the acetabulum as much as possible. For patients over 3 years old, surgery is required.

According to statistics, children who are treated in infancy and young children have the best prognosis, and the hip joint can fully return to normal in the future. Therefore, for newly born infants and young children, the corresponding diseases need early detection and early treatment.

For infants and young children, when using special pantyhose to wear them, because they are too soft like clothes, they cannot achieve the effect of stretching their thighs well, making the treatment effect poor. When using the Pavlik harness to wear it, because the Pavlik harness has more straps and is tied to the neck, chest, calf and sole of the feet, etc., the skin of infants and young children will have a lot of streaks and scars. It causes discomfort. When using a plaster frame to stretch and fix the thighs, the plaster frame needs to be specially made according to the size of the infant, making it unusable, and the plaster frame cannot be used according to the degree of recovery of the patient's hip dysplasia. Adjustment, so that the use effect is also not good.

Therefore, the tools used in the prior art conservative treatment need to be improved and optimized.
