process. The results for the effects of mechanical loading, inserted pin,
and material inhomogeneity on the surface remodeling behavior are omit-
ted here; they can be found in Qin et al. [1]. We distinguish five loading
cases:
• Case 1:

) =
n
× 2 MPa
(
n
= 0.8, 0.9, 1, 1.1, and 1.2),
P
(

) = 1500 N, and
no other type of load is applied
• The extended results for this loading case are shown in Figure 4.2
to study the effect of external pressure on the bone remodeling
