Introduction. Fracture Fixation is a balance of Biology and Mechanics. Race between Bone Healing and Construct Failure. Promote bone healing while considering the mechanical stability/durability of the fixation construct.
Components of Direct Bone Healing • Contact Healing – Direct contact between the fracture ends allows healing to be with lamellar bone immediately • Gap Healing – Gaps less than 200-500 microns are primarily filled with woven bone that is subsequently remodeled into lamellar bone
Depending on the type, severity of the fracture and distance between bone fragments, bones may heal directly by building new bone onto the fracture site (direct bone healing or contact healing) or may heal in a process like endochondral bone formation (indirect bone healing).
8 kwi 2023 · During this article, we will work through each of these steps in order and detail before touching on primary healing, factors affecting fracture healing, and methods of stimulation of fracture healing.

Fracture is a break in the structural continuity of bone. The healing of fracture is in many ways similiar to the healing in soft tissue wounds except that the end result is mineralised mesenchymal tissue i.e. BONE. Fracture healing starts as soon as bone breaks and continues modelling for many years Introduction
Bone Biomechanics. Bone is anisotropic - its modulus is dependent upon the direction of loading. Bone is weakest in shear, then tension, then compression. Ultimate Stress at Failure Cortical Bone.
