Study of effect of free omental graft and white fat graft on bone healing rabbit

Osteogenesis, Osteoiduction, Osteoconduction are threeessential elements of bone regeneration along with final biding between host bones and grafting material.In this study, six-month-old male New Zealand rabbits with abody mass of about 2.5 kg were used. 15 rabbits randomlydivided into three groups. In group I in both hands ulna bonewas defected (3*1.5 mm) without any treatment. Just someomental and white fat cutted and removed. In group II ulnabone of right hand was defected (3*1.5 mm) and omentum of animal itself was used for grafting. In group III ulna bone of left hand was defected and white fat abdominal was used for grafting. Movements of animal were evaluated in days 3, 6, 9,12,15,20,25,30,40 of observation.In all three groups First radiography was done just afteroperation. And also in days 15, 30, 45of experiment. Accordingto data obtained all three type of callus in group II were vastly generated. Osteogenesis procedure in omentum group was higher than other groups.Histopathology results in group I showed Perriosteal and modularly bridging callus beside bone marrow and fibroses tissues were vastly generated. In group II Osteogenesis in sponge form and blood vascularatin was so much and small amount of Fibroses tissues were seen. Furthermore Perriosteal and modularly bridging callus were noticed. In group III Between fibroses tissue some fat tissue were also visible. Alongwith fibroses tissue Osteogenesis was in progress. Fibroblastschanged to octeocytes. Result obtained from histomorphometry indicates that differences among groups were meaningful (Pvalue
