Several microsurgical techniques have been described for the treatment of osteonecrosis of the talus (ONT). Recently reported in children, vascularized periosteal grafts showed promising revascularizing properties. We report a novel technique using a pedicled periosteal graft from the first metatarsal bone to treat steroid-induced early Ficat-Arlet stage III ONT in an 11-year-old boy. The patient presented initial favorable clinical and radiological results which were maintained at 34 months during the last follow-up. Through this original technique, and basing on the powerful osteogenic and vasculogenic propreties of periosteal flaps, we could effectively induce bone revascularization and prevent further collapse of the talar dome.

Literature on the reconstruction of the proximal femur in skeletally immature patients with the use of an epiphyseal transplant is scarce and with variable results depending on the indication. We report successful outcomes using a modified vascularized fibular epiphyseal transplant in a 4-year-old boy with an oncologic lesion. We discuss the advantages of supplementing the standard graft with a vascularized fibular periosteal tissue. The vascularized fibular epiphyseal transplant (VFET) is an effective option in the reconstruction of the epiphysis in skeletally immature patients, owing to the advantage of restoring both the joint function and the growth potential in a single surgical operation. Multiple reported cases demonstrate the effectiveness of this complex technique in upper extremity reconstruction. However, literature is scarce regarding its use for the reconstruction of the proximal femur and hip joint. Through this article, we report the use of a VFET in the reconstruction of a proximal femur in a 4-year-old boy after an intra-articular wide excision of an epithelioid hemangioendotelioma. We also discuss the advantages of designing the flap as a composite vascularized epiphyseo-osteo-periosteal flap.
