Bone consists of two forms: woven and lamella

Woven vs Lamellar Bone
Property	Woven Bone	Lamellar Bone
Definition	"Primitive", immature	"Mature" bone, remodelled from woven bone
Found in	Embryo and new-born, in fracture callus, metaphyseal region of growing bone, tumours, osteogenesis imperfecta, and pagetic bone.	Throughout the mature skeleton in both cancellous trabecular and cortical bone.
Composition	Dense coarse-fibred collagen, varied mineral content, greater turnover, more cells per unit volume with random arrangement, no lamellae.	Formed by intramembranous or endochondral ossification, contains collagen fibres.
Organisation	Randomly arranged collagen fibres, disorganised	Highly ordered, stress-oriented collagen fibres
Mechanical Properties	Isotropic	Anisotropic
Strength	Weaker, more flexible, more easily deformed	More stiffness and strength
