To The Editor:I was very interested to read the article "Femoral Component Revision
with Use of Impaction Bone-Grafting and a Cemented Polished Stem"
(2005;87:2499-507), by Schreurs
et al. They found a 100% survival rate after a mean of 10.4 years of
follow-up, which is impressive despite there being only thirty-three hips in
the study.My enquiry is regarding the preparation of the bone graft. The authors
commented that a Novio Magus bone mill (Spierings Medische Techniek, Nijmegen,
The Netherlands) was used to produce particles with a diameter of 2 to 5 mm,
but they did not report any other treatment of the graft. In particular, was
the morsellized bone washed or defatted?
