Complete range of modular and
fixed-head reamers to match
surgeon preference and optimize
O. R. efficiency, presented in fully
sterilizable cases.
Studies
1
have demonstrated that
the pressures developed within
the medullary cavity through the
introduction of unreamed IMnails can
be far greater than those devel oped
during reaming − but this depends
very much upon the design of the
reamer.
After a three year development study
2
involving several universities, the
factors that determine the pressures
and temperatures developed during
reaming were clearly established.
These factors were applied to the de -
velopment of advanced reamers that
demonstrate significantly better per -
form ance than the best of previous
designs

Large clearance rate resulting from reduced number
of reamer blades coupled with reduced length of
reamer head to allow for effective relief of pressure
and effi cient removal of material

Forward- and side-cutting face combination produces
effi cient material removal and rapid clearance

Double-wound shaft transmits torque effectively and
with high reliability. Low-friction surface fi nish aids
rapid debris clearance

Smaller, 6 and 8mm shaft diameters are designed to
reduce IM pressure.
