Background: Aseptic nonunion is a challenging complication of humeral shaft fractures, with reported rates ranging from 1% to 10% depending on the initial treatment method. Surgical management aims to restore stability and promote biological healing. Objective: To analyze the epidemiological, clinical, radiological, therapeutic, and functional outcomes of aseptic humeral shaft nonunion treated with plate fixation and bone grafting. Methods: We conducted a retrospective single-center study including 50 patients treated surgically for aseptic humeral shaft nonunion between February 2011 and February 2021. All patients underwent plate osteosynthesis combined with autologous bone grafting. Clinical, radiological, and functional outcomes were evaluated. Results: The prevalence of aseptic nonunion was 11.9%. The mean patient age was 42 years. Road traffic accidents were the most common cause of injury. Union was achieved in all patients, after the initial procedure in 48 cases and after revision surgery in two cases. The mean time to union was 5 months. Functional outcomes were excellent or good in most patients. Complications were limited to transient radial nerve palsy and minor donor-site morbidity. Conclusion: Plate fixation combined with autologous bone grafting remains a reliable and effective treatment for aseptic humeral shaft nonunion, providing a high union rate and satisfactory functional outcomes.
