EVALUATION OF RADIOLOGY AND HISTOPATHOLOGY OF ALTERNATIVE IM PIN AS FIXATION MATERIAL IN HUMERUS FRACTURE OF DOMESTIC PIGEON
(Columba livia domestica)
The aim of this research was to figure out the biocompatibility of alternative bone pin that made of monitor lizard’s costae as internal fixation of humerus fracture in pigeon through radiology and histopathology examination. This research used 10 male domestic pigeons age of 4 to 5 month weighing 300 to 500 g which randomly divided into two treatment groups, metal intramedulery pin (K-1) and others implanted with bone pin (K-2). Radiology examination performed on 7th, 14th, 21th, 28th, 35th and 42th post-surgery in ventrodorsal views. Furthermore, histopathology examination performed after euthanasia at the day of 60th of post-surgery. The result of radiology examination showed that internal fixation applied with bone pin has a similar potential with metal intramedulery pin. Histopathological evaluation indicated the amount of osteoclast, neovascularization and connective tissue of K-1 are greater than K-2 (P>0, 05). In other side, the number of osteocytes of K-2 are larger than K-1 (P>0, 05). It also showed statistically non-significant (P>0.05) of prosperous implant’s indicator between two treatment groups. As a result, metal intramedullary pin and bone pin could consider as internal fixation material of avian orthopedic case.
