Foot valgus is a deformity caused by abnormal tendon development of the foot, accompanied by flat foot and scaphoid collapse. The middle point of the leg, the center of the Achilles tendon and the center of the calcaneus are in line.
The appearance of foot valgus not only affects people's image beauty, but also affects people's health. Nowadays, many people want to choose an effective way to treat the phenomenon of foot valgus. As a result, corrective heel cups
came into being.
In addition, foot valgus can also cause ankle valgus deformity, and some people believe that the cause of the disease is tibialis anterior muscle tension, and passive correction of ankle can be restored to a neutral position of 90 degrees. Others believe that the foot valgus caused by intrauterine compression of the fetus is not caused by tibialis anterior muscle tension. Patients with foot valgus incline outward when walking to support the medial foot touching the ground, and metatarsal flexion behaves the deformity. It can cause pain in the medial foot and significantly affect the supporting phase. When walking, the center of gravity of the body mainly falls on the anteromedial part of the ankle. Limited ankle dorsal flexion affects anterior and posterior tibial movement, which increases valgus. The talus and calf joints are painful and unstable. Early support phase may include knee joint overextension, lack of strength in pedal separation, and limb clearance obstacles in swing phase.
Corrective heel cups can effectively regulate the plantar pressure distribution, such as reducing the excessive load on metatarsal bone in diabetic patients and preventing foot ulcer. The corrective heel cups can also adjust the abnormal biomechanical changes of the foot, adjust the force lines of different axes, provide reasonable support, improve the function of the foot, improve the force lines of the ankle joint and the whole lower limb and trunk, improve the gait and so on.
