Prophylactic Intramedullary Rodding After Femoral Lengthening in Patients With Achondroplasia and Hypochondroplasia.

Background: Femoral fracture after femoral lengthening in patients with achondroplasia and hypochondroplasia is a frequent complication, occurring in up to 30%. The purpose of this study is to demonstrate the effectiveness of prophylactic intramedullary rodding in preventing this complication.

Methods: Multicenter retrospective study involving 86 femoral lengthening procedures in 43 patients with achondroplasia or hypochondroplasia.

[Optimization of radiological scoliosis assessment].

Most scoliosis are idiopathic (80%) and occur more frequently in adolescent girls. Plain radiography is the imaging method of choice, both for the initial study and follow-up studies but has the disadvantage of using ionizing radiation. The breasts are exposed to x-ray along these repeated examinations.

Vascularized periosteal graft from the first metatarsal bone: a new technique to prevent collapse of osteonecrosis of the talus in children. A case report.

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.

Composite vascularized fibular epiphyseo-osteo-periosteal transfer for hip reconstruction after proximal femoral tumoral resection in a 4-year-old child.

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.

Treatment of congenital pseudarthrosis of the tibia with vascularized fibular periosteal transplant.

The vascularized fibular periosteal flap has been recently described and showed solid angio and osteogenic features. We report the use of a free vascularized fibular periosteal transplant in the treatment of a El-Rosasy-Paley Type III congenital pseudarthrosis of the tibia in a 7-year-old boy, with a prior unsuccessful surgery at the age of three. The contralateral fibular periosteum was used to replace two-thirds of the hamartomatous tibial periosteum.
