In phase I, incidence study of long bone fractures in goats was undertaken. The incidence of long bone fractures among all surgical conditions in goats was 6.97%. Female goats were more commonly affected. Higher incidence of fractures was noticed in hindlimbs and in young goats between six months to one year of age. The most commonly affected bones were metatarsal and metacarpal. Majority of the goats had simple fractures; oblique fractures being more common. Majority of the long bone fractures in goats were due to automobile accidents. In phase II, the research was conducted in 18 clinical cases of goats affected with tibial fractures. The goats were randomly divided into three groups with six goats in each group. The feasibility of three different techniques of ORIF using 3.5mm locking plates applied as an “internal fixator” were evaluated using clinical, radiological and biochemical changes on pre-operative day, post-operative day 0, 15, 30, 60 and 120. In group I, LCP, in group II, locking SOP plate and in group III, locking reconstruction plates were applied. In all the groups, normal weight bearing was achieved by day 30. Functional weight bearing was observed in all the groups by day 60. Group I (LCP) showed slightly better weight bearing throughout the period of study compared to group II and group III. Radiological evaluation revealed that fracture healing in all the groups was through secondary callus formation. Initiation of periosteal callus was noticed on day 15 in all the groups. Apparent bridging of the fracture site was noticed in all the groups on day 30. Cortico-medullary union was established on day 60 and initiation of remodelling was observed on day 120. The complete union and initiation of remodelling of fracture was observed to be earlier in group III, followed by group II and group I. The physiological and biochemical parameters fluctuated within normal limits and no significant alterations were noticed. Intra-operative complications included iatrogenic fractures, monocortical placement of screws and accidental placement of screw at the fracture site. The post-operative complications noticed were limited to infection of operative site resulted in uneventful recovery of the cases. Implant related failures were not observed in any of the groups. The implants were removed between day 120 to 150 and no complications were noticed during implant removalEnglishThesis
