What are the congenital hand malformations and how many are the congenital malformations of the uppe

The cause of congenital hand malformations is not clear, and according to clinical data, it is believed that familial inheritance is one of the main causes of this disease, and congenital hand malformations are as follows: 1Giant Finger:

A rare deformity in which one finger, several fingers, or all hands are enlarged, and may be dysplasia or due to neurofibromatosis. Finger bones and soft tissues increase in length and width. Neurofibromatosis itself is often inconspicuous, while the hypertrophic part is prominent.

2.Short fingers: one or more fingers are shortened due to abnormal embryonic development, which may be accompanied by a decrease in the number of phalanges and a shortening of the metacarpal bones.

Malformations often occur with syndactyly or polydactyly. The shape and function of the fingers are generally normal.

3.Syndactyly: the light one has an incomplete webbed membrane only between the two fingers; In heavier cases**, the subcutaneous soft tissue merges, and the nails are separated.

In severe cases, the 2nd to 5th fingers are connected to each other, and the phalanges are incomplete and multiple joint deformities occur. The distal phalanx of the finger fuses with the nail while the rest of the finger is normal, which is called the terminal fusion type. Syndactyly occurs between the middle and ring fingers and is usually bilateral.

It may also be complicated by fused phalanx, short finger, polydactyly, syndactyly, or foot deformity. Multiple finger syndactyly, affecting the function of the hand. 4.

Polydactyly: often with syndactyly, brachydactyly, and other deformities. Polydactyly is most common with the thumb, followed by the little finger, and is sometimes bilateral.

There are 3 types of deformities: Abnormal soft tissue masses with no adhesions to bone. Repeat the fingers, containing phalanges, joints, tendons, etc., and the proximal phalanx form joints with the metacarpal head or bifurcated metacarpal bone.

Completely extra fingers, including a complete metacarpal bone with multiphalanges. 5.Floating thumb:

It is a congenital absence of the first metacarpal bone, poor development of the thumb, absence of the thenar muscle, and some mobility of the flexor and extensor muscles of the thumb.

1 Polydactyly: Polydactyly is the most common congenital anomaly of the hand, mostly in the thumb, followed by the little finger. 2 Syndactyly:

Syndactyly has a variety of manifestations, which can be sporadic and is inherited in an autosomal dominant manner. Its incidence is second only to polydactyly. 3 Short finger deformity:

It is a genetic disease. The metacarpal bones and phalanges of brachydactyly are quite numerous, but they are short, and the range of deformities can be a longitudinal row or series of phalanges or short metacarpal bones, or a horizontal row or a series of phalanges or short, which generally occurs in the first finger and can be sporadic. It is often accompanied by deformities such as syndactyly and absence of pectoralis major.

4 Absent finger deformity: hereditary. The thumb and thumb shortening are considered autosomal dominant.

It can be a partial absence of a finger, a finger or several fingers, and the anodactyly is often combined with a congenital annular sulcus malformation. 5 Giant finger deformity: the cause is unclear and rare.

Macrodactyly is an overgrowth of the affected finger, which can be one finger or several fingers.
