Abstract
This research evaluated the efficacy of two different locking plates, namely, the
polyaxial locking plate system (PAX) and the locking reconstruction plate, for femoral
fracture repair in cats. 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.
