Background: Tibial fractures are common long bone injuries caused by high-energy trauma such as road traffic accidents or falls. Managing fractures, particularly in the proximal and distal metaphyseal regions, is challenging due to complex biomechanics and the risk of malalignment. Poller screws (blocking screws) have been introduced as an adjunct to intramedullary nailing (IMN) to improve alignment and stability.Objectives: This study evaluates the effectiveness of Poller screws in stabilizing tibial metaphyseal fractures by assessing their impact on alignment, healing time, and functional outcomes.Material and Method: This prospective study, conducted over two years at a tertiary orthopedic center, included 40 patients with tibial metaphyseal fractures who met specific inclusion criteria. All patients underwent IMN with Poller screw augmentation. Data on fracture alignment, healing time, and functional outcomes were analyzed using statistical methods.Results: The mean age of the 40 patients was 38.2 years, with 80% of injuries caused by road traffic accidents. Postoperatively, varus/valgus angulation improved from 9.8° to 1.5° and remained stable at 1.7° at union. The mean union time was 11.2 weeks, with delayed union in 12.5% of cases. Functional outcomes were favorable, with 70% of patients achieving excellent results, 20% good, and 10% fair. No non-union cases were reported.Conclusion: Poller screws significantly improve fracture alignment, reduce malalignment risks, enhance biomechanical stability, and promote faster healing. Their use should be considered a standard adjunct in tibial metaphyseal fracture fixation.
