Why is the shoulder most likely to become dislocated?

The shoulder joint – a ball-in-socket mechanism, with the round top of the arm bone fitting into a groove in the shoulder blade – is the most mobile joint in the body. It can turn in several directions. Yet that mobility can leave the shoulder unstable, even though it’s anchored by muscles, tendons and ligaments. Of all the joints in the body, the shoulder is the most likely to become dislocated.
