Clubbing is a clinical finding characterized by bulbous fusiform enlargement of the distal portion of a digit (see the image below). Clubbed fingernail. When the profile of the distal digit is viewed, the angle made by the proximal nail fold and nail plate (Lovibond angle) typically is less than or equal to 160Â°. In clubbing, the angle flattens out and increases as the severity of the clubbing increases. If the angle is greater than 180Â°, definitive clubbing exists.
The white blood cells or lymphocytes produced by these lymph nodes kill bacteria and viruses entering the body.
