The paper presents methods and results of the assessment of elasticity modulus changes during fracture healing. Long bone fractures can be healed using external fixators - devices that stiffy fix fracture fragments using parallel to the bone, attached with pins frame. This method affords to take profits both from healing and diagnostics of fracture during osteogenesis. Osteogenesis can be precisely determined with mechanical properties like strength and elasticity inside the fracture slot. The treatment of long bone fractures by external fixators affords a unique opportunity to control the healing of the fracture by measuring the tension on the frame, that occurs under the load given to the bone and rely on the mechanical properties of the fracture. Elasticity modulus can be one of the best description methods of mechanical properties of the bone. It can also be used for more precise and direct description of changes of mechanical properties inside the fracture slot.
