Femoral fracture after harvesting of autologous bone graft using a reamer/irrigator/aspirator.

Abstract

A case of postoperative fracture in the donor femur after obtaining autologous bone graft with a reamer/irrigator/aspirator is presented. This procedure was successful in healing a difficult femoral nonunion, but the patient sustained a fracture of the contralateral (bone graft donor) femur 20 days after surgery. A mechanical analysis is conducted of this case and recommendations are made. Unrestricted weightbearing on a limb that has undergone reamer/irrigator/aspirator bone graft harvesting, particularly in a noncompliant patient, is probably inadvisable. If possible, one should obtain bone graft from the same limb as the fracture being treated because this will leave the patient with one unaltered limb for mobilization.
