Functional Outcome of Solid Interlocking Nail in Open Tibial Fracture at a Tertiary Care Center: A Descriptive Cross-sectional Study.

Introduction: There is a high incidence of open fractures accounting 23% of all tibial fractures. The minimal soft tissue and precarious blood supply of the shaft of tibia make these fractures vulnerable to complications. The treatment should be decided through thoughtful analysis for personality of injuries and the status of the soft tissue. Intramedullary nailing allows stable fixation with minimal soft tissues dissection and preserve the soft tissue and allows early joint motion with higher rate of union. The purpose of our study was to find the outcome of open tibial fractures lower than Gustilo type IIIb, that were treated by unreamed solid interlocking intramedullary nails.

Methods: A descriptive cross-ectional study was conducted from December 2021 to June 2023 after taking approval from ethical committee. All 34 patients treated with solid interlocking intramedullary nail, without reaming for open tibial fracture during 18 months period were included in the study. Final follow up was done at one year and the outcome was assessed by Modified Ketenjian's criteria.

Results: The mean time of union rate was 15.82±3.95 weeks. Complications were: superficial infections in 4 (11.76%) patients and deep infection in 1 (2.94%) patient. Using Modified Ketenjian's Criteria, 26 (76.47%) patients had an excellent result followed by good in 7 (20.59%), fair in 1 (2.94%) and there was no case with  poor outcome.

Conclusions: Solid intramedullary interlocking nail is an effective treatment with minimal soft tissue dissection for open tibia fracture less than GA III B as it provides stable fixation with early mobilization and provides a high rate of union, less complication and early return to function.
