Abstract

Treatment of comminuted long bone fractures in dogs is burdened by the risk of bone healing complications. The immediate complications are due to soft tissue damage while the late complications of fracture healing include delayed union, nonunion and malunion. Bone grafting with locking compression bone plate and barrier membranes as guided bone regeneration aids in enhanced fracture healing with minimal complications.The aim of this study was to evaluate the use of hydroxyapatite bone graft with collagen membrane as guided bone regeneration in long bone comminuted fractures in dogs.

Six dogs irrespective of age, breed and sex and suffering from comminuted long bone fracture in Radius, Femur and Tibia were surgically repaired with suitable bone plate as internal fixation technique. The hydroxyapatite bone graft with collagen membrane was used as an adjunt to the fracture site.

Out of six dogs, one dog showed early bone healing, four dogs depicted slow healing on radiographic evaluation and one dog with femur fracture immobilized with LCP showed screw pull out by 15th post operative day.
