Finger girdle syndrome is a girdle syndrome that occurs in the finger area and is a specific congenital disorder with a low incidence that manifests as a ring-like narrowing of the finger area. The fasciculation syndrome is not hereditary and is a defect caused by the intrauterine environment of the embryo. After the rupture of the amniotic membrane in early pregnancy, resulting in a relative decrease in amniotic fluid, the fetus’s limbs are entangled and compressed by the ruptured band of amniotic membrane, and local ischemia forms fasciculations, with obstruction of venous and lymphatic reflux leading to edema or hypertrophy of distal limbs. Finger fasciculation syndrome is a special congenital disease, the finger area at birth can be seen completely or incompletely surrounding the soft tissue of the limb depression, most often in the calf, toes, forearms, fingers and other parts of the limb, can be accompanied by limb deformity. Finger girdle syndrome is recommended for early surgical treatment if the girdle compresses the nerves and blood vessels.
