GENTILE, Luciano et al. Defectos óseos diafisarios postraumáticos en la extremidad superior de niños. Rev. Asoc. Argent. Ortop. Traumatol. [online]. 2017, vol.82, n.4, pp.277-293. ISSN 1852-7434.

Introduction: The aim of this study was to evaluate the results achieved in children with chronic segmental bone defects at the humerus or forearm. Methods: Nine children, treated between 2005 and 2015, presenting long bone upper extremity fractures that got infected resulting in segmentary bone defects were retrospectively evaluated; all lesions had 6 or more months from trauma. Seven patients were male and two female, with an average age of 9.9 years. Four defects were located at the humerus, three at the ulna, and two at the radius. All patients had had previous surgical interventions (average 3.7), originating bony defects that averaged 4.5 cm. Time from initial trauma to definitive surgery averaged 21.8 months. Results: Follow-up averaged 2.2 years. Union was achieved in all patients. A cement spacer was used in one case, in another case a free fibular bone graft was used. Two patients with humeral defects had significant shortening. All patients returned to their recreational and sports activities without limitations. Conclusions: The combination of different types of bone autograft, various plaques placed bypassing the lesion and the induced membrane technique allowed us to obtain consolidation and return to normal activity in the nine children with segmental bone defects in humerus, ulna or radius.
