Granulation tissue will withstand 100% strain whereas bone will only withstand 2% strain. Granulation tissue forms then your fibrous tissue than fibrocartilage and you then get cars forming and then you get the bone and that process slowly reduces the strain as you get less movement as all the tissues become a little bit more rigid which allows the formation of the next layer of tissue. To reduce the strain the gap can be widened - bone ends reabsorb all the fracture becomes progressively stiffer by the formation granulation tissue callous and finally bone. Formation of the callus creates greater stability and reduced movement at the fracture site and the strain decreases. Management of Strain: • Strain is equal to the change in length divided by the original length • The body will initially resorb the end of the bone to the fracture and now increases the fracture gap and therefore reduce the strain which aids the initial healing process. Post Operative Assessment: • Once we've done the fracture repair we have to take post-operative radiographs to make sure that • the fracture is completely aligned • The positioning of the implants • The encroachment of implanted joint a soft tissues of the bridging of growth plate in young animals § If this is not addressed it can lead to angular limb deformity. Monitoring: • This interval may be great if the animal is doing well and varies with the implants employed for example a external ______ may require a weekly examination is the complication rate is higher whereas a plate repair may only require an examination at monthly intervals if it is progressing well • Radiographic assessment should be made: • Prior to the removal of implants • If progression is not as anticipated • Or if there is evidence of sepsis Summary: • You want to assess the animal • You want to then take radiographs • You don't want to score the fracture • Then you want to consider what forces need be counteracted • Fix the fracture and then take post-operative radiographs so as to be confident that the fracture suitably repaired • Monitor the progress of the fracture clinically and radiographically particularly if the fracture healing appears prolonged an animal is not progressing as anticipated
