Arch foot

Introduction The arched foot refers to the arch of the foot is significantly deeper than the physiological state, and the foot is curved forward and backward. The arched foot system is caused by the long bones of the humerus and the long flexor contracture of the toe or the atrophy of the calf triceps. It is a fixed deformity of the longitudinal arch height beyond normal. Can have a family history, rare on one side, bilateral deformity symmetry, occasionally one side is more serious. The disease is progressive, symptoms appear after 3 to 4 years old, and the termination period is 17 to 18 years old, and the deformity no longer develops.

Cause

The arched foot system is caused by the long bones of the humerus and the long flexor contracture of the toe or the atrophy of the calf triceps. Intrinsic is common in lower extremity nerve palsy, hereditary ataxia and spina bifida.

Clinical examination:

The clinical manifestations of the longitudinal arch are arch bridge shape, often accompanied by claw-toe deformity, and may also have varus varus or mild valgus, and the humeral head surface forms painful spasm. The contracture of the fascia is visible on the sole of the foot.

Different types of high arch deformities due to different pathological changes: if the medial longitudinal arch is elevated and the lateral longitudinal arch is normal, the first metatarsal needle toe deformity of the first metatarsal can be seen. The high bow is accompanied by a contraction with a horseshoe high arch. The high bow with the gastrocnemius muscle and the soleus muscle paralysis is characterized by a high toe.

Differential diagnosis

Multiple examinations should be performed during diagnosis, and attention should be paid to the identification of sequelae of poliomyelitis.
