Abstract:
The present clinical study was conducted on 6 dogs with long bone fractures using Polyaxial Locking plate System with ages ranging 5 to 20 months old. Four of the six dogs were male and two were female. Three dogs non-descript, Labrador, Lhasa Apso and Golden Retriever each. The body weight ranged from 10 to 20 kg. Orthopaedic examination, radiography and clinical symptoms were used to diagnose long bone fractures. These fractures were stabilized with 3.5 mm Polyaxial locking plates (PAX). Radial fractures appraoched cranio-medially, a cranio-lateral approach for femur and a cranio-medial approach for tibia, allowing for bone plating with Polyaxial Locking (PAX) system. Four dogs had good implant stability without any complications. Whereas plate bending was noticed on 30^th Post-operative day in two dogs. However, intermittent weight bearing was noticed by 45^th post- operative day.The dogs with grade V lameness were progressed to Grade I by the end of the 30^th post-operative day in four dogs, while two more had accomplished grade I at the end of the 60^th post-operative day. PAX system offers angulation of locking screws, prevent growth plates from being damaged in young dogs and screw penetration in fracture lines, resulting in a rigid stabilization. Limited contact with the bone resulted in preserving the periosteal vascular, which promoted early fracture healing, limb ambulation and an earlier return to normal range of motion.
