Evaluating low level laser therapy for fracture healing in dogs

Twelve dogs having long bone fracture were randomly divided into two groups. Fractures of both groups were immobilized by intramedullary pinning. Group I was the treatment group with immobilization along with low level laser irradiation therapy. Group II acted as control. A lesser degree of inflammation, exudation and pain was observed in group that undergone low level laser therapy. None of the animals of both groups was able to bear weight on their fractured limb on two post-operative day. Weight bearing progressively increased in both group but it was more in group I. Radiographic evaluation revealed initiation of periosteal reaction as early as 7^th post-operative day, marked callus was recorded on 21^st post-operative day and commencement of remodeling from 42^nd post-operative day in laser treated group.
