Abstract

Caffey (6) states that "these all appear at approximately 16 years and fuse with their respective processes at approximately 25 years."

Twenty cases of early appearance of the annular vertebral ossification centers were collected from a review of approximately 400 cases seen over a ten-week period at Jackson Memorial Hospital, Miami, Fla.
