Abstract
Background: The use of synthetic bone substitute,b-tricalcium phosphate (β-TCP) as an osteo-conductive material and platelet-rich plasma (PRP) as an osteo-inductive material is the alternate strategies for replenishing bone loss. Thus, the present study was conducted to evaluate the bone healing efficacy of β-TCP and PRP combination in dogs with long bone fracture repaired with threaded intramedullary pinning. Methods: Fifteen dogs were selected, which were allotted to two groups irrespective of age, breed and sex. In six dogs of Group I intramedullary pinning was performed, while in nine dogs of Group II β-TCP and PRP was applied at fracture site after stabilising with intramedullary pin. Clinical and radiographic examinations were conducted preoperatively and postoperatively on 15th, 30th and 60th day. Result: The mean weight bearing and radiographic union scores were better in group II animals as compared to group I at different time intervals. The present findings suggest that β-TCP and PRP effectively enhances the bone healing in dogs with long bone fracture.
