Abstract

Abstract: Osteosarcoma is a relatively uncommon diagnosis that often requires limb salvage techniques in young patients. Due to the potential long‐life expectancy of these patients, techniques which avoid prostheses are preferred to limit the need for future revision surgeries. This case report presents a 9‐year‐old male diagnosed with intramedullary well‐differentiated osteosarcoma of the tibial diaphysis. This limb salvage procedure utilized a rotational ipsilateral vascularized double barrel fibula autograft measuring a total of 24.5 cm when harvested but osteotomized to lengths of 11 and 12.5 cm limbs to reconstruct an 11 cm tibial shaft defect. Anterior chamfer cuts were performed on one limb allowing it to be inserted intramedullary while the second limb was then placed with an inlay technique posterolaterally and then compressed with a carbon fiber plate. The patient recovered well initially postoperatively but was taken back for revision of the carbon fiber plate 10 weeks postoperatively secondary to asymptomatic loosening of the proximal screws. The patient subsequently healed and experienced full graft incorporation with expected hypertrophy of the graft. At most recent follow‐up at 19 months, the patient reported no pain and was utilizing the extremity in a normal fashion with no activity limitations. In this report, we present a case of the use of an ipsilateral rotational double‐barrel fibula autograft for limb salvage in a pediatric patient with lower extremity intramedullary osteosarcoma.
