Dynamic correction device and method for intervening abnormal development of children's hip joint

Abstract

The invention discloses a dynamic correction device and method for intervening abnormal development of children's hip joint. The dynamic correction device comprises a hip abduction contour structure,a hip extension contour structure and a femoral head contour structure; the hip abduction contour structure is connected with the hip extension contour structure; the hip extension contour structure is connected with the femoral head contour structure. The abduction and extorsion of the hip joint during extension are limited; the abducting function is limited by means of certain resistance and position adjustability; the moving range of the abduction angle and adduction angle is limited; resistance intervention can be provided within the limited range; the locked position can be limited; the extorsion of the hip joint is absolutely limited; certain deformation compensation is provided structurally for extorsion correction; the extorsion tendency is corrected under the reactive force of deformation.

Description

technical field [0001] The invention relates to the technical field of hip joint orthoses, in particular to a dynamic orthopedic method for interfering with abnormal development of children's hip joints. Background technique [0002] In the absence of standardized daily training guidance, children are likely to develop deformed lower limbs, such as excessive external rotation of the hip joint, anterior pelvis tilt, and asymmetrical walking posture on the left and right sides. The maturity of the hip joint can be restored to the normal structural shape under the external guidance intervention, and it will not affect the behavior after maturity. In clinical practice, orthopedic fixtures are generally used to correct the hip joint, and at the same time, staged rehabilitation training is carried out, but Orthopedics and training are carried out in time-sharing, and the treatment effect on the development of the hip joint is general. Currently, therapist's manual therapy is the m...

Problems solved by technology

[0003] The hip joint orthosis currently used limits the angle of hip abduction and adduction, which will cause hard extrusion for children with hip joint dysplasia. For cartilage damage, it is necessary to provide a device that can stably support the structure of joint movement, limit and ensure that the joint can move in one degree of freedom, and exercise can help promote the exercise capacity of the soft tissue around the joint, promote blood circulation, and ensure the growth of the joint adequate supply of nutrients
