Hyperconvex nail

What it means

When viewed on end (with the digit tip pointing toward the examiner's eye) the curve of the nail forms a tighter curve of convexity.

No objective standards were identified for this finding. Another way to describe this finding is to say that the observed curve has a smaller radius than does the typical nail. The affected digits should be specified.
