Abstract

Background: Intramedullary nailing is considered a superior method for treating patients with extra-articular tibial fractures. However, achieving and maintaining control of the distal fragment during the procedure can present significant challenges. The use of Poller screws has been shown to create a stable mechanical environment, thereby facilitating the healing process for acute fractures.
Aim of study: To assess the efficacy of intramedullary nailing with the use of poller screws for the treatment of tibial metaphyseal fractures.
Patients and methods: This prospective cohort study included 30 patients with displaced proximal or distal tibial metaphyseal fractures. All participants underwent intramedullary nailing enhanced by the application of Poller screws. The follow-up assessment focused on the range of motion in the knee and ankle, time to union, postoperative complications, and overall satisfaction with the treatment outcomes.
Results: The age of included patients was 35.5±3.5 years old. Tibial fractures were united in all cases. Knee range of motion was more than 120° in 50%, from 90-120° in 46.6%. The range of ankle plantar flexion was > 30° in 57% and 20-30° in 33.3%. The results were satisfied in the majority of patients. The most observed postoperative complications in were ankle swelling (20%) followed by pain (17%).
Conclusion:  The incorporation of Poller screws into the intramedullary nailing technique for tibial metaphyseal fractures proved effective in achieving optimal fracture alignment.
