Effect of electromagnetic field on surface bone remodeling.
described. Figure 5.24 lists the corresponding variation of inner radius with
time
t.
It can be seen from Figures 5.23 and 5.24 that an electromagnetic
field also has a significant effect on the bone remodeling process. When
the applied electric potential is relatively small—say, φ = 0 or 5 V—both the
bone porosity and inner radius can increase quickly with the time
t,
whereas
the bone porosity remains nearly constant when the applied electric potential
increases to φ = 10 V and above. The variation of inner radius has a similar
trend to that of bone porosity.
