    • Abstract:
      Background: Dynamic nailing by placing only one screw on one side of the nail shortens the surgical time and reduces the complications during surgery and secondary dynamization. This study aimed to investigate the healing of dynamic intramedullary nailing (IMN) of tibial fractures. Methods: This cross-sectional study was done on 67 patients with dynamic IMN in 5th Azar Hospital, Gorgan, Iran, in 2015-2018. Complications, union time, Radiographic Union Score of Tibia Fracture (RUST) score, and Johner-Wruhs criteria were analyzed based on their grouping in AO classification. Results: The average age of the patients was 33.2 ± 13.0 years. Most of the fractures were closed type (71.6%), type C (43.4%). The mean healing time was 14.62 ± 4.38 weeks and RUST score was 8.90 ± 1.26. There was no significant difference between locations of fracture and the healing time or RUST score (P > 0.05). The healing time in the comminuted fractures (e.g., type C) and open tibial fractures was statistically longer than the simpler type (e.g., type A or B) and the mean radiological score in type C fractures was significantly lower (P < 0.05). The mean Johner-Wruhs criteria score of fractures was 46.31 ± 4.49, so that 61 patients had excellent results, four patients had good results, and two patients had fair results. Conclusion: Dynamic IMN of closed and middle third tibial fractures and simpler types of fractures (e.g., type A or B) have faster healing. Nevertheless, it is better to be more cautious for fixation of open or comminuted fracture (e.g., type C). [ABSTRACT FROM AUTHOR]
