Description

Knee, ankle and foot orthosis for children

Technical Field

The utility model belongs to the technical field of medical instrument's technique and specifically relates to a children knee ankle foot orthopedic ware is related to.

Background

At present, more and more children suffer from genu varum or genu valgus, and the popular expressions are X-shaped legs and O-shaped legs. The deformity of the leg not only affects the shape and the body building, but also has great influence on the health of human body, the knee eversion or the knee inversion destroys the normal force distribution of the knee joint, so that the stress borne by one side of the joint is increased, the opposite side is relatively reduced, and simultaneously, the friction between the patella and the femur is increased due to the change of the lower limb force line. When the time is long, pain may be caused when the knee joint walks, the movement of the joint may be affected, and osteoarthritis may easily occur. Therefore, the correction needs to be performed as early as possible. The orthoses commonly used at present are knee, ankle and foot orthoses for children.

Chinese patent with publication number CN208910623U discloses a knee ankle foot orthosis, which comprises a thigh fixing sleeve, a shank fixing sleeve and a foot fixing sleeve, wherein the shank fixing sleeve is connected with the foot fixing sleeve through a movable joint arranged on the foot fixing sleeve, the thigh fixing sleeve and the shank fixing sleeve are both of a U-shaped semi-surrounding structure, at least one rubber strip is respectively arranged on the thigh fixing sleeve and the shank fixing sleeve, at least two rubber strips are arranged on the foot fixing sleeve, fixing strips are arranged on both sides of the thigh fixing sleeve, supporting strips are arranged on both sides of the shank fixing sleeve, a U-shaped groove is arranged on one end of each fixing strip close to the shank fixing sleeve, one end of each supporting strip close to the thigh fixing sleeve is hinged to the U-shaped groove, and a fixing block.

Because children's size of body is different, in order to can be fine cooperation children's shank, reach good correction effect, knee ankle foot orthopedic ware often need closely to butt with children's shank and carry out the centre gripping. However, this arrangement results in a child being able to wear only a few thin undergarments when wearing the knee, ankle and foot orthosis.
