Cancellous bone graft was harvested from opposite side iliac crest and ipsilateral side distal femoral canal.
The peak stress in the cortical and cancellous bones decreased markedly as shown in L1 models [Figure 2]a, whereas cancellous bone alone showed an increase in L2 and C2 models [Figure 2]b.
A morphological study was conducted to measure the width of buccal cortical bone, inferior cortical bone, lingual cortical bone, cancellous bone and height of mandibular symphysis in adult subjects aged between 18 and 30 years with skeletal class I (Angle's class I) and class III (Angle's class III) with mandibular prognathism.
After getting the cortical bone geometry the cancellous part was modeled by subtracting the tibia model with the shell model to obtain cancellous bone geometry as shown in Fig.
As bone graft source the standard bone graft is autogenous particulate cancellous bone and marrow (PCBM) from the ilium.
The 29 mm diameter flat-back Delta III baseplate removed the second most cancellous bone and the second most overall glenoid bone (3.
Another possible solution, investigated in this paper with the use of finite element analysis (FEA) is to modify the screw implant trajectory for providing more contact with the cortical, rather than cancellous bone.
2 mid-body wings for increased fixation in cancellous bone and six proximal "teeth" for optimal cortical bone purchase.
00 mm distal to the growth plate were evaluated regarding the bone mineral density of the whole tibia metaphysis, the cancellous bone density and the cortical bone density.

Computed tomography (CT) detected a widening of the frontal bone with osteolytic changes of the cancellous bone of the diploe.
Based on the micro CT data, the mean cancellous bone volume was significantly higher (45%) among women treated with PTH, compared with the placebo group.
