Final answer:
A bony exostosis is a bone spur. Subluxation is a partial dislocation, while dislocation is a complete separation of joint surfaces. Both can cause pain, swelling, and limited movement.
Step-by-step explanation:
A bony exostosis is a type of bone spur that forms on the surface of a bone. It can cause pain and limited mobility in the affected area. Subluxation refers to a partial dislocation of a joint, where the joint surfaces are not fully separated. Dislocation, on the other hand, occurs when the joint surfaces are completely separated. In both cases of subluxation and dislocation, the joint loses its normal alignment, causing pain, swelling, and limited movement.
