The metaphysis may be divided anatomically into three components based on tissue content: a cartilaginous component (epiphyseal plate), a bony component (metaphysis) and a fibrous component surrounding the periphery of the plate. The growth plate synchronizes chondrogenesis with osteogenesis or interstitial cartilage growth with both appositional bone elongation in conjunction with growth in width, so bearing load and responding to local and systemic forces and factors balance one another mechanically.
During childhood, the growth plate contains the connecting cartilage enabling the bone to grow; at adulthood (between the ages of 18 to 25 years), the components of the growth plate stop growing altogether and completely ossify into solid bone.[2] In an adult, the metaphysis functions to transfer loads from weight-bearing joint surfaces to the diaphysis.[3]
