Introduction: Bone is considered a tissue with good healing properties, and many bone defects can heal spontaneously under appropriate conditions. Extreme bone loss can hinder remodeling and regenerative processes, leading to bone nonunion. This condition negatively impacts the patient's quality of life with a severe socioeconomic burden. Many treatment options have been proposed, but none can be defined as a gold standard, mainly due to the variety of clinical presentation, bone loss, and quality.
Presentation of case: We present a 15-year-old case of tibial nonunion following multiple traumas. The patient was treated non-surgically at the beginning, but the external fixator positioning was required due to a delay in the healing process. Following further trauma, the patient showed progressive anterolateral angulation, severe lateral procurvation, and a progressive worsening of the pseudoarthrosis. The severe bone loss and poor quality of the bone surrounding the defect required a special technique called Huntington procedure that consists in a vascularized bone autograft from the ipsilateral fibula to achieve mechanical and biological healing of the pseudoarthrosis. The patient recovered well and returned to full weight bearing without a mobility aid.
Discussion: We report this case of complex tibial nonunion and malalignment, developed after subsequent traumas. Due to the multiple complications, and the poor biology a Huntington procedure was required to provide mechanical stability and a biological boost to the bone defect.
Conclusion: This case report shows a complicated case requiring several surgeries and treatment options and confirms the potential benefit of the Huntington procedure for treating a tibial severe bone loss.
