What is clubbing in the body?

Clubbing is a physical sign characterized by bulbous enlargement of the ends of one or more fingers or toes (Figure 44.1). Proliferation and edema of connective tissue result in loss of the normal angle between the skin and nail plate and excessive sponginess of the nail base. Clubbing is usually acquired and is associated with certain cardiopulmonary and gastrointestinal disorders, but may occur in congenital or familial forms. Acropachy is an alternative term for clubbing. Acquired clubbing is often reversible when the associated condition is treated successfully.

What are the abnormalities of clubbing?

Early clubbing must be distinguished from several other abnormalities of the fingertip. These include: (1) increased nail curvature , a normal finding in many adults (especially blacks); (2) chronic paronychiae, in which the soft tissue at the base of the nail is inflammed and swollen; and (3) felons or abscesses of the terminal pulp space, in which there is swelling over the palmar surface of the fingertip. In none of these conditions, however, is the fundamental angle between nail and terminal phalanx altered. A simple maneuver (described by Schamroth) readily differentiates true clubbing from these pseudo-clubbing conditions. The examiner asks the patient to hold the two thumbs back to back with the two fingertips and interphalangeal joints aligned. Because the base angle is unaltered in these conditions, an elongated, diamond-shaped area of empty space is apparent. In true clubbing, this empty space is lost. (Schamroth, while himself ill with subacute bacterial endocarditis, noted this finding as one of the earliest signs of clubbing; he also reported that the window of empty space reappeared 2 months after his endocarditis had been treated successfully.)

What is the angle between the nail plate and the skin overlying the proximal part of the distal?

Normally, the angle between the nail plate and the skin overlying the proximal part of the distal phalanx is about 160 degrees or less. With clubbing, proliferation of tissue under the nail plate causes this angle to increase to more than 160 degrees. In fact, the angle may be entirely lost and the nail plate and skin lie in a straight line (180-degree angle). As clubbing progresses, the angle exceeds 180 degrees. Eventually, the profile of the fingertip becomes bulbous.

How to tell if a nail is floating?

With clubbing, the root is separated from bone by connective tissue and edema; pressure upon the nail plate moves it toward the bone.
