Megaprosthesis use in Paprosky III/IV femoral defects in non-oncological patients: analysis of survival, clinical, and functional outcomes after an average follow-up of five years.

The MEG for reconstruct III-IV femoral defects is a good therapeutic option that offers an acceptable clinical-functional result. Short-term and medium-term survival was greater than 80%. The most frequent complications are seromas and MEG dislocation. The use of constrained liner and abductor system reconstruction is essential to prevent the dislocation.
