Using Food Grate Stainless Steel Rods for Internal Fixation of Transverse Fractures in Rabbits

This project was designed to replace the medical stainless steel pins (MSP) which used in internal fixation of the transverse fractures femoral bone in rabbits by the food grate stainless steel rods (FGSR) 2.25 and 2.5 mm which used in the food industry. 175 adult local bree d rabbits were used from 2008 – 2019, 60 of them used to induced transverse fractures in the mid shift of femoral bones, the o thers employed to remove 1cm of diaphysis bone and replaced by either xeno - bony sheep implantation in 26 rabbits, or replaced by xeno - bony bov ine implantation in 75 rabbits , while the others14 rabbits replaced by the synthetics bony nano scaffold implantation, then all fixed by FGSR as internal fixation devices for the induced femoral fractures or fixation the implanted devices. The parameters w hich were used for evaluation were, the p hysical and general examination , laborato ry analysis for elements ratio, clinical application with radiographic and histopathological examination . The results revealed FGSR easy to find and use and handling , with lo w prize and high economic values, and the chemical elemen ts ratio the same as in the MSP , nobody rejection or complication , not changed before and within and after implantation and sterilization , give stability, and support the body weight , and the rabbits quickly used affected limb in walking and running, the FGSR visible radio graphically with good alignment of fractures bones with normal healing radiographic finding, while the histopathological examination shows normal histopathological changes during fr actures healing processing . The conclusion FGSR size 2.25 – 2.5 mm can be used strongly and successfully in internal fixation of induced transverse mid shift fractures of femoral bones in rabbits instead of the MSP.
