Giant feet

Introduction The giant foot is abnormally developed into a deformed tissue due to diseases such as congenital toe disease, which makes the patient's foot bigger than ordinary people. Congenital "Growth toe" is a very rare congenital lower extremity limb deformity with an incidence of about one in ten thousand. It is often found at birth or shortly after birth. The toe is thick and can be thickened with age. It grows longer, and the growth of the giant toe stops when the whole body develops basically stops. This disease often leads to ugly foot shape, unstable walking, and some nerve compression syndrome due to the lack of suitable shoes, resulting in limb numbness and even toe necrosis.

Cause

The cause of this disease formation is also very complicated. The main cause is the excessive growth hormone in the process of embryo growth, lack of growth inhibitory factor, and the variation of transfer factor is also related to its occurrence, but the exact pathogenesis is still not clear.

Diagnosis is based on clinical practice.

Clinical typing

Barsky (1967) divided the giant toe/fingery into two types:

1 Stable: The giant toe/finger is a congenital malformation, but grows in proportion to other toes/fingers after birth.

2 Progressive type: The giant toe/finger grows much faster than other toes/fingers, which is mainly caused by excessive fibrous adipose tissue proliferation.

Differential diagnosis

Differential diagnosis of giant feet:

1. Foot deformity: Foot deformity refers to the abnormal shape or structure of the foot. The shape of the normal human foot is maintained by the symmetrical outer and inner muscles. Some congenital or other disease causes can cause foot deformity. .

2, clubbing (toe): refers to the (toe) end of the soft tissue thickening like a drum-like expansion, arched bulge, a longitudinal ridge and transverse ridges are highly curved, the surface is glassy, called the clubbing (acropachy. Clubbing finger). Also known as the faded finger. The angle between the side nail and the nail skin of the healthy person's finger is 160 degrees. With the occurrence of the forest finger, the angle can be gradually increased to 180 degrees or more. Pressing the root of the nail can have a noticeable elasticity and tenderness. The finger-like fingers appearing in different diseases have different fingertip colors. The forest finger of the congenital heart disease of the hair group, the finger is often purple and black, the nail arc is reddish brown, the capillary of the nail bed is increased, and the blood flow at the finger end is increased. In patients with lung disease, the fingertips of the forest finger are dry and not smooth, yellowish white, and the blood vessel proliferation is not significant. Oral refers to the more common symptoms of certain diseases in the internal medicine.

3, and refers to (toe) deformity: the so-called toe (finger) deformity refers to the five toe (finger) between two or more sticking together and not separated, is born at birth innate Sexual abnormality.

4. Giant finger (toe): Giant finger (toe) is a congenital malformation characterized by an increase in the volume of the fingers or toes. The incidence in congenital malformations of the extremities is very low, about 0.9%.
