Outcomes of Non-vascularized Fibular Grafts in Proximal Humerus Aneurysmal Bone Cysts.

Introduction This study focuses on the management of primary aneurysmal bone cysts (ABCs) through comprehensive curettage, hydrogen peroxide lavage, and non-vascularized strut fibular grafting. Methods The research encompassed 20 cases, predominantly males (80%), with an average age of 11.35 years. Patient assessment involved thorough history-taking, clinical examinations, and radiological evaluations, including plain radiographs, CT scans, and MRI. The study evaluated healing, bone consolidation, and complications, with patients assessed using the Musculoskeletal Tumor Society (MSTS) upper limb score. Results and discussion The results demonstrated a mean MSTS score of 91.55%, indicating favorable outcomes compared to prior studies. The utilization of non-vascularized autogenous fibular grafts offered effective mechanical stabilization and facilitated an early return to normal function, even prior to complete cavity filling. Our research underscores the efficacy of this treatment approach for primary ABC, particularly in achieving satisfactory functional outcomes. Moreover, the findings contribute to the understanding of optimal management strategies for ABC, considering factors such as patient age, lesion location, vascularity, and size. Conclusion The study advocates for the adoption of thorough curettage, hydrogen peroxide lavage, and non-vascularized strut fibular grafting as a reliable treatment modality for primary ABC. This approach highlights its potential to enhance patient outcomes and functional recovery.
