INTEGRATED EFFICACY OF BIO-OSS® AND DEMINERALIZED BONE MATRIX FOR CRITICAL SIZED ULNA DEFECT HEALING IN A PIGEON (COLUMBA LIVIA)

Abstract

In order to know the mechanism of critical sized defect healing with bone grafts were investigated by radiology and histology in pigeon. Purpose of this study was to estimate the effect of Bio-Oss with DBM for critical sized ulna defect healing in pigeon. Total 12 physically healthy adult pigeons (Columba livia) underwent for defect healing using two different bone grafts. Birds were randomly divided into 3-groups of four pigeons in each. Osteotomy procedure was performed using Isoflurane inhalation anesthesia and mixed with O2. A 1-cm bone piece of left ulna was removed from mid-shaft and filled with Bio-Oss® and demineralized bone matrix (DBM). Birds were sacrificed at their end-point of 3, 6 and 12 weeks for radiographic and histological examinations. Results of this study suggest that combination of Bio-Oss® with DBM for new bone formation in pigeon ulna is effective treatment resulting improved defect healing without any complications. It is concluded that Bio-Oss with DBM may be used for defect healing and osteosynthesis in birds.
