Description

Closed reduction brace for dislocation of hip joint

Technical Field

The utility model relates to the technical field of medical equipment, concretely relates to hip joint dislocation closed brace that resets.

Background

Congenital hip joint dislocation is a common congenital deformity of children, and is characterized in that the femoral head loses the normal involution relation with the acetabulum in a joint capsule, so that the femoral head cannot normally develop before and after birth, walking is affected, and most patients have ischemic necrosis of the femoral head after adults with serious consequences and belong to disabling diseases. The treatment principle of the disease is to diagnose as early as possible and treat the disease in time. Treatment should be initiated immediately after birth once diagnosis of congenital hip dislocation is established; the greater the age at the start of treatment, the poorer the effect.

At present, the traditional treatment mode adopts conservative treatment or operation treatment, the conservative treatment adopts frog type position plaster or frog type orthotics and the like for fixing treatment, the frog type position plaster is fixed for the purpose of enabling the femoral head to be stably restored in the acetabulum and shaping the joint, but the femoral head can be separated again due to violent movement, the course of disease is long at the same time, the course of disease treatment needs 6 months, the patient takes a picture for rechecking once every month, the fixing device is adjusted, the nursing is difficult, and in the treatment period of 6 months, the infant is fixed in the frog type position, can only take the horizontal position, can not turn over, can not sit, can not crawl, influences the food intake and urine management, and seriously influences the growth and development of the infant; the frog type orthosis has the defects of insufficient external fixing force, easy looseness and the like, so that the femoral head of the affected hip joint is not effectively fixed after being reset, and the probability of re-dislocation is high; when in a frog type position, the femoral artery passing through the space between the adductor longus muscle and the iliocostalis muscle is pressed, so that the blood circulation of the femoral head is directly influenced; in a frog-type position, the enlarged labrum may compress the epiphyseal groove, resulting in impaired development of the femoral head and even deformity.
