Radiological Evaluation of Fractures Healing Processing Fixed by Food Grate Stainless Steel Rods in Rabbits

Abstract

This study was designed to follow up the radiological changes of the fracture healing process of the induced transverse femoral mid shift fracture in rabbits that fixed by food grate stainless steel rods (FGSR). Eight adult local breed rabbits were employed to induce complete transverse mid shift fracture in the femoral bone, under general anesthesia with highly aseptic technique. The fracture fragments fixed with FGSR, the study followed for more than two months by weekly radiographic examination, which revealed, the fracture healing occurs by secondary or indirect bone union, in which the new bone formation can be visible radiographically at the end of 2 nd week Post operati on (p. o.) around the fractures line which still visible, the callus formation increase in volume and density at the end of 3 rd week, at the end of 4 th weeks bony bridge formation and disappear of fracture line, at the end of the 6 th weeks radiological unio n occurs and the FGSR removed and remodeling phase started and continuous next week the conclusion the fracture healing processing of the induced fracture in the femoral bones in rabbits which fixed FGSR as internal fixation methods can be determined radio graphically.
