Vascularized proximal fibular epiphyseal transfer: Two cases

SummaryVascularized proximal fibular epiphyseal transfer in children enables reconstruction of long-bone epiphyseal defect, while conserving axial growth potential. This technique was applied in two children for diaphyseal-epiphyseal reconstruction of the proximal humerus and distal radius respectively, using a graft vascularized only by the anterior tibial artery. There were no major complications during harvesting. Both cases showed transplant growth, of a mean 0.5 cm/year. Joint function in the proximal humerus reconstruction was satisfactory, with functional range of motion. In the distal radius reconstruction, range of motion was almost zero; insufficient transplant growth induced radial club hand, requiring partial correction by progressive lengthening using an external fixator. In case of severe bone loss, fibular epiphyseal-diaphyseal graft vascularized only by the anterior tibial artery is a feasible attitude.
