Trabeculae contribute to the strength of bone while minimizing material usage by forming a complex, three-dimensional latticework of interior struts.12

These bony processes are organized into an orderly pattern of intersecting plates and spicules that are specifically aligned parallel to the lines of major compressive or tensile force. By acting as cross-braced supports, trabeculae provide maximal rigidity and structural support while leaving open, honeycombed spaces that reduce the overall weight of the bone. This efficient architecture allows the human skeleton to maintain necessary strength and flexibility, with the open structure also serving to dampen sudden stresses during load transmission through the joints.21
