8. what is the difference between a dislocation and a subluxation?

Brief Explanations:

A dislocation is a complete separation of the bones that form a joint, where the articular surfaces lose all contact. A subluxation is a partial separation, where the joint bones are shifted out of their normal position but still retain some contact with each other.

Answer:

A dislocation is a full separation of joint bones (no remaining contact between articular surfaces), while a subluxation is a partial separation of joint bones (some contact between articular surfaces is still maintained).
