Plating and autologous bone grafting resulted in union in only 75 % of persistent non-union of the humeral shaft. The persistent nature of the humeral shaft non-union could be attributed to deviating from validated rules for surgical treatment and/or the presence of a surgical site infection.
An 18-year-old male with neurofibromatosis type I was treated for congenital pseudarthrosis of the tibia using the Masquelet induced-membrane technique with internal fixation by retrograde implantation of a transplantar intramedullary nail. Bone healing was obtained at the expense of malunion with external rotation and 5.5cm of lower limb shortening. A motorised intramedullary-lengthening nail (Fitbone, Wittenstein, Igersheim, Germany) was implanted. This treatment was successful in correcting the rotational malalignment and limb length discrepancy. The motorised nail Fitbone may be a valid option for treating complex cases of limb length discrepancy, including those combined with limb deformities.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
