Pestle finger is called pestle finger because the end of the finger is hyperplastic, hypertrophic and widened, abnormally enlarged and misshapen, shaped like a drumstick.
Pestle finger is a deformity of the finger. It may be related to chronic hypoxia, toxic injury, and metabolic disorders at the end of the limb. When the end of the finger is hypoxic, the capillaries are abnormally enlarged and dilated, and the soft tissues are proliferated, resulting in an abnormally enlarged deformity at the end of the finger and the formation of a pestle-shaped finger.
Acquired mortar and pestle finger can occur in a variety of respiratory, cardiovascular and nutritional disorders such as bronchopulmonary disease, subacute bacterial endocarditis, cyanotic congenital heart disease, cirrhosis, Crohn’s disease, and so on.
Once pestle finger is detected, it is important to consult a doctor to determine the cause of the disease and to intervene early to obtain better results.
