Quantitation of digital clubbing by shadowgram technique

Arch Dis Child. 1979 Feb;54(2):145-6. doi: 10.1136/adc.54.2.145.

Abstract

Finger clubbing was quantified from the magnified silhouette of the right index finger in controls and patients with clubbing, using a simple shadowgram technique. There was good correlation between clinical assessment and measurement of both the profile angle and the hyponychial angle. The hyponychial angle appeared to be a more accurate indicator of clubbing than the profile angle.
