Apophysis

The apophyses (singular: apophysis) are the normal bony outgrowths that arise from separate ossification centers and eventually fuse with the bone in time. The apophysis is a site of tendon or ligament attachment, as compared to the epiphysis which contributes to a joint.

When unfused, they can easily be mistaken for fractures.

Given the similar development with epiphyses, primary bone lesions that are typically located in the epiphyses can also occur in apophyses.
