Novel Dual Bicolumnar Fibula Graft Reconstruction of Distal Humerus in Pediatric Patients After Massive Bone Resection: A Report of Two Cases.

CASE: We describe 2 case studies, involving a 10-year-old girl with an aneurysmal bone cyst and a 12-year-old adolescent boy with Ewing sarcoma. The patient with Ewing sarcoma was previously managed with wide surgical excision and fibular graft reconstruction and subsequently experienced significant graft resorption, hardware failure, and fracture 24 months after operation. A revision limb salvage attempt was undertaken. In both cases, fibular strut grafts were harvested and fixed with intramedullary k-wires to recreate the medial and lateral columns of the distal humeral triangle.

CONCLUSION

The technique achieved complete osseous integration, structural support, and functional restoration of the elbow in both cases, with good functional outcomes.
