So imagine you're slicing a nice garlic-cheese bagel one morning, and you lacerate the distal phalanx of your pollex — in other words, you cut the tip of your thumb.
What it looks like I'm looking at here is potentially clubbing of the distal phalanges. It's an enlargement of the furthest part of your finger, where you actually have down sloping of the nail as well.
这看起来是指骨远端杵状突起 这是手指最远的部分的扩大 实际上指甲也向下倾斜。

The phalanges/fəˈlæŋdʒiːz/ (singular: phalanx/ˈfælæŋks/) are digital bones in the hands and feet of most vertebrates. In primates, the thumbs and big toes have two phalanges while the other digits have three phalanges. The phalanges are classed as long bones.
