Abstract: The present study included 41 clinical cases suffering from 45 long bone fractures in dogs which were treated by intramedullary pinning using open and closed technique. The cases were divided into five groups. In Group Ia (n=4) and Group Ib (n=6) closed stabilization carried out using simple Steinmann pins and end threaded intramedullary pins, respectively. In Group IIa (n=8) and Group IIb (n=11) open stabilization carried out using simple Steinmann pins and end threaded intramedullary pins, respectively. In Group III (n=16) open stabilization of supracondylar and distal third fractures of long bone were treated using end threaded intramedullary pins. Higher fracture incidence was recorded in males (63.41%), dogs less than 6 months of age (40%) and weighing 10-20 Kg (35.55%). Automobile accident was the major etiology of fractures (46.34%) and non descript dogs were affected most commonly (29.27%). The C arm guided closed simple and end threaded pinning was feasible in 66.7% and 46.15% cases, respectively. Higher feasibility of closed intramedullary pinning was observed in dogs more than one year of age (77.78%), in transverse fractures (77.78%), and in mid shaft fractures (75%). Simple pinning was associated with more proximal migration complications (41.67%) whereas no such complication was seen in end threaded pinning. End threaded pinning provides better stability than simple intramedullary pinning even in unstable fractures and therefore, recommended for diaphyseal and supracondylar fractures of long bones. Closed intramedullary pinning is associated with shorter operative time, reduced postoperative care and minimum wound related complications but it is feasible only in recent cases of fractures with minimal overriding. Long term follow up was available for 41 fractures and 35 healed satisfactorily. In conclusion, end threaded pinning though tedious but provides more stability as compared to simple intramedullary pinning. The C arm directed closed intramedullary pinning is recommended in skeletally mature dogs with transverse, mid shaft fractures with minimal overriding.
