Role of Dynamization in Interlocking Nailing of Fractures of Tibia and Femur
Journal Title: Journal of Bone and Joint Diseases - Year 2018, Vol 0, Issue 0
Abstract
Introduction: Intramedullary interlocked nailing has been the most widely accepted and practiced strategy of the management of diaphyseal fractures of tibia and femur, however, associated with delayed and/or non-union in many cases. Dynamization forms one of the various methods proposed to overcome the problem of non-union. is study aims at assessing the need and effectiveness of dynamization in tibial and femoral diaphyseal fractures. Materials and Methods: A total of 218 diaphyseal fractures of femur (77) and tibia (141) were selected for the prospective study in the time frame of 01-06-2015 to 31-08-2016. All patients underwent closed or open interlocking nailing, and clinical and radiological follow-up was done for 1 year with the results being obtained on radiological assessment. Results: In femur interlocking nailing, the average union time was 22.4 weeks for non-dynamized and 21.6 weeks for dynamized nails. For tibial interlocking nails, it was observed to be 22.5 weeks for non-dynamized and 20.1 weeks for dynamized cases. Conclusion: Delayed and non-union continue to be a major problem associated with intramedullary interlocking nailing of diaphyseal fractures of tibia and femur, for which dynamization has been advised. In our study, the progress of union and the average time to union were observed in dynamized versus non-dynamized cases, and it was observed that dynamization had a denite role in enhancing tibial diaphyseal fracture union while having an equivocal effect on femoral diaphyseal fractures, as compared to nondynamized cases
