Twelve cases of femoral fractures in domestic cats were randomly allocated into two groups, each consisting of six cats. Group I cats were treated with the PAX plate, while Group II cats were treated with the locking reconstruction plate for fracture fixation. Anesthetic combination of diazepam was administered at a dose of 0.30 mg/kg body weight intravenously, and ketamine hydrochloride at a dose of 11 mg/kg body weight intravenously, while maintenance was done using isoflurane at an initial concentration of 5 per cent, followed by 1-2.50 per cent. Clinical, radiological, and biochemical parameters were assessed preoperatively and at various postoperative intervals up to 60 days. Both groups achieved accurate alignment and stabilization of fracture fragments, with satisfactory outcomes observed in terms of osseous callus formation, stable implant positioning, and reduced fracture gaps. Functional limb usage assessments revealed progressive improvement, with most cats achieving excellent limb function by day 60. Serum biochemical analyses indicated consistent trends within physiological ranges, suggesting successful healing processes with both fixation methods. Notably, the PAX system demonstrated a lower incidence of postoperative complications, while cases treated with the locking reconstruction plate exhibited complications such as plate bending and screw pullout. Overall, the study highlights the effectiveness of both fixation systems in femoral fracture repair in cats, with PAX showing superior performance in minimizing implant-related complications.EnglishThesis
