Aseptic pin 100 sening is caused by bone injury which occours while insertion of the pins stresses or compressive by cyclic loading. These stress ses are mainly influenced by pin diameter and length. In this study, the function graphics of the mathematical formulas that used for calculations ofthe compressive stresses have been drawn by a computer. After evaluation of the se graphics we have concluded that the incidence of pin loosening could be lowered by using a fıxator geometry that allows usage of shorter and thicker pins.}, number={1}, publisher={Turkish Association of Orthopaedics and Traumatology}
