A partial dislocation or misalignment of a joint is known as what?
lesya [120]
A partial dislocation or misalignment of a joint is known as subluxation

This is when a joint slides out of position but can slide back in on its own. This is different to a luxation (or full dislocation) where the joint completely comes out and has to be put back in with human assistance.

I hope this helps! I'm happy to answer any other questions you might have :)
