Advantages and Disadvantages of using Food Grate Stainless Steel Rods for Internal Fixation of Femoral Transverse Fractures in Rabbits (Review Study)

The present study designed to focus on the advantages and disadvantages of using food grate stainless steel rods (FGSR) as internal fixation methods for induced transverse fractures in the mid shift of the femoral bones in rabbits.200 cases were collected from 2007 to 2020, all these cases were employed to induced transverse fractures in the mid shift of femoral bone, 100 of them used the rods for internal fixation, 80 of the cases used the rods for fixation the natural xenbony implantation from sheep or calves, and the others 20 cases used the rods for internal fixation of the synthetics nano bony implantation .The physical, chemical, clinical and radiographic parameters were used for evaluation, the physical and chemical analysis showed that the rods not change during sterilization, implantation or when exposed to different types of ray besides the chemical constant is about the same level measurement of the medical intramedullary pins (IMP), while the clinical observation revealed that the rods can used strongly and successfully for fracture fixation and support the animal to bear the weight, the limb used for walking gradually after 24-48 hours p. o. with some cases shown the FGSR pulled from the bone, other suffer from infection with pus formation with lateral deviation of the stifle joint or re-fracture. While the radiological finding revealed that the FGSR insert and fix the fractures fragment and the bony implantation, the pins seemed stable and fit the intramedullary canal and fracture fragments, while some cases shows that the pin not insert properly inside the femoral bone with case of multible and comminuted fractures, other case shown the FGSR pass and penetrate the stifle joint. The conclusion is, there are many advantages with minor or very little disadvantages for using the FGSR as internal fixation of the induced transverse fractures in the mid shift of the femoral bones and for natural and synthetics bony implantation in rabbits.
