Intramedullary Nailing of Tibial Fractures. Is There a Relationship Between the Entry Point and Its Final Alignment?
Main Article Content
Abstract
Materials and Methods: We carried out a retrospective, descriptive, observational study between January 2015 and January 2019 of patients with diaphyseal fractures of the tibia, treated with intramedullary nailing. Radiographs were obtained in the immediate postoperative period and then every two months. The eighth-month radiograph, in which clear signs of bone consolidation could be observed, was taken into account to assess tibial alignment.
Results: When the nail entry point was central, there was only a 0.021 chance (or 2.1%) of any significant misalignment in the immediate postoperative period and after 8 months. In contrast, when it was medial, the chances of a valgus tendency were >0.85 (or 85%) already at the first image, i.e., post-surgery; and when it was lateral, this possibility was modified and deepened according to the time elapsed until the image achieved in the patient.
Conclusion: A marked and continuous relationship was observed between the entry point of the intramedullary nail and the alignment of the tibia after bone consolidation.
