[The internal remodeling of compact bone in children]

The internal remodeling of bone in children is characterized by the presence of large osteones with irregular undermineralized deposits and large Havers canals. These Havers canals undergo a lateral displacement by progressive erosion of their internal side. These remodeling units decrease progressively in number and in dimensions and disappear after the age of 12 years. The metabolic necessities of childhood would explain the importance of the remodeling. The decentred form evokes a relation to strains imposed on the bone.
