Morphology

pseudarthrosis = arthrosis (transparent) = pseudo + arthr + osis

The word is transparently formed as pseudo- + arthrosis, yielding the literal sense of a false joint.

Etymology

Pseudarthrosis comes from pseudo- 'false' and arthrosis 'joint', the same arthro- you see in arthritis. So pseudarthrosis literally means 'false joint', which fits when a broken bone does not heal and instead forms a joint-like, movable area.
