Fig. 6. A putative explanation of faster growth in radial bone. Schematic cross
sections of tissues. (A) Laminar bone. Circumferential alignment of woven bone
struts results from a saltatory and discontinuous activity of the periosteum
(profiles expressed on the right of each section). Repeated onset and arrest
of production are suspected to be time-consuming. (B) Longitudinal bone. Same
phenomenon as in laminar bone (although less pronounced). (C) Radial bone.
Radially aligned bone struts are produced continuously by the periosteum.
Efficiency of growth is increased. This holds independent of bone
porosity.
