Rational Utilization of the Stress Shielding Effect of Implants

Fracture healing is an extremely complicated biological process. The primary factor affecting fracture healing is the blood supply to the fracture site, which is the basic assurance of successful treatment, and as well as sustained blood supply to the fracture site, a favorable local mechanical environment is also an essential requirement for fracture healing. Research in past years has shown that the mechanical environment favorable to fracture healing includes two aspects: stability of the fracture ends (exclusion of harmful movement and shear stress) and stimulation of physiological stress. In the past, clinical treatment of fractures focused on the means to ensure the stability of the fracture ends, while modern treatment for fracture gives more regard to the physiological requirements for fracture healing.
