During childhood, the long bones (in the arms, legs, and back) grow at the ends of the bones, whereas the flat bones (such as the skull) have a different pattern of growth. Adult bone actually continues to expand, although very slowly. Bone also continually undergoes .

Anatomic differences: child vs. adult. The long bone in a child is divided into four regions: the diaphysis (shaft or primary ossification centre), metaphysis (where the bone flares), physis (or growth plate) and the epiphysis (secondary ossification centre). In the adult, only the . Approximately 10% of the skeletal mass of an adult is remodeled each year. The bone remodeling period consists of the duration of the resorption, the osteoclastic reversal (the phase marked by shifting of resorption processes into formative processes), and the formation periods of .

Complete fractures. In children, the outer layer surrounding the bone, the periosteum, is much stronger than in adults but is loosely attached. Muscles arise from, and are inserted onto, the periosteum rather than the bone itself and this permits coordinated growth of the bone and the soft tissues.
