Nail clubbing
(重定向自Clubbed fingers)



Nail clubbing, also known as digital clubbing, is a deformity of the finger or toe nails associated with a number of diseases, mostly of the heart and lungs. Clubbing for no obvious reason can also occur, but is rare. Hippocrates was probably the first to document clubbing as a sign of disease, and the phenomenon is therefore occasionally called Hippocratic fingers.
