Background Despite the improved rate of union reported in tibial shaft fractures, there continues to be a small number of patients with delayed union and nonunion who present a dilemma to the surgeons. Because the spectrum of injuries to the tibia is so great, many methods of treatment are available to treat tibial nonunions. Aim The aim of the study was to evaluate partial fibulectomy as an easy, simple, and effective treatment option in the treatment of certain types of tibial nonunions. Patients and methods This prospective study included 20 patients with established tibial nonunion. All patients were evaluated clinically in laboratory and radiologically before surgery and followed up until after complete union of the tibial fractures. Results All fractures were united at an average duration of 15 weeks (range 10–19 weeks) after partial fibulectomy, with acceptable alignment in the coronal and sagittal planes. There were no neurovascular complications, no limitation of joint motion, and no problems at the fibulectomy site. Conclusion The results were very satisfactory and were significantly in favor of using this easy, simple procedure in the treatment of certain patients of tibial nonunions.
