Methods: Between January 2007 and December 2013, one hundred and twelve patients of distal tibia that involved the distal 6 cm of the tibia were treated at our hospital with reamed intramedullary nailing with use of two distal interlocking screws and one proximal screw in dynamic mode. The augmentation was done with poller screws whenever it was necessary. The nailing of fibular fractures was done in 27 cases. There were 85 males and 27 females with a mean age of 30.9 (range: 20 to 72). Eighty fractures were closed whereas 32 were grade 1 open fractures. Results: The average time to union of the closed fracture was 15.4 weeks (range: 12 – 28 weeks). The healing times for the primarily nailed compound Grade I averaged 17.8 (range: 15 - 34 weeks). After minimum follow-up of one year, rate of primary union was in 97.32%. One case of broken nail required revision surgery. There were three cases of delayed union and two cases of non union. In one case there was deep infection which required exchange nailing with antibiotic impregnated nail. There was breakage of interlocking screws in three cases but fracture had united. In twenty two cases acceptable malalignment of the tibia was observed after union. The outcome was determined at a minimum of one year in our study based on the criteria of Johner and Wruhs. Out of 112 patients, 79 patients had excellent results, 29 had good results and 4 had fair results. Conclusions: The dynamic osteosynthesis of distal tibia by interlocking nail and judicious use of poller screws is an effective alternative for the treatment of distal metaphyseal tibial fractures.展开更多
