Congenital fasciculation syndrome is a common clinical case in which complete or incomplete depressions surrounding the soft tissues of the limbs are seen at birth, most often in the lower legs, toes. forearms, fingers, etc. Clinically, it is often divided into four degrees, 1 degree: the fascia is only embedded in the subcutaneous; 2 degrees: the fascia is deep into the fascia and does not affect the circulation of the distal limb; 3 degrees: the fascia is deep into the fascia and affects the circulation of the distal limb, and the limb end is swollen and has a change in color, which can also be accompanied by nerve damage; 4 degrees: congenital amputation. The main purpose of treatment is to remove the fascia compression, let the limb develop normally, improve limb edema, for the fascia compression of blood vessels, nerves should be early surgical treatment. The surgical method is to completely loosen the fascia and do Z-plasty with a dyadic skin flap. The traditional view is that the fascia should be operated in 2-3 stages to prevent necrosis of the skin flap and affect the blood flow of the limb. With the improvement of medical level and technical methods, we believe that it is completely possible to do Z-type forming directly for the release of the fascia in 1 stage of surgery, which reduces the number of surgeries, shortens the time of treatment, and enables the child to get good development.
