The risk of lower bone density was increased according to the increase in BCd levels after adjusting for eGFR and covariates, in which a significant interaction between BCd and eGFR existed.
At 3, 12 and 48 weeks of age bone density was increased in vertebral spine, but was, as shown before, statistically indistinguishable from wild type at 24 weeks of age ([12]; Figure 1B).
Bone mineral density was increased in IL-15R-deficient mice and was not reduced after ovariectomy.
Interestingly, however, when wild-type mice were infected with an avirulent Salmonella strain, which can induce OPG, osteoclast development was suppressed and bone mineral density was increased.
The present study manifests the following: in the 1 mm coronal bone defect area surrounding the implant, bone mass and density were increased merely by the SLA implant surface, but in the open bone defect area, 0.5 and 1.0 mg/mL concentrations of rhBMP-2 were more effective at promoting bone regeneration and osseointegration.
Whether the observed increased bone density is spurious or relates to increased weight gain, weight bearing or other factors is unclear.
While the terminology suggests that the decrease in bone density is brought about by increased cortical resorption activity [ 30, 34], an alternative pathway to bone density reduction would be a strong increase in vascularization, leading to the periosteal bone being primarily cancellous.
While ultimately repairing or avoiding damage to the bone structure and increasing bone density both improve mechanical properties, increasing bone density is the more important contributor to bone strength.
The higher radiology scores in Devogelaer grading the more pronounced redistribution of bone, ie. loss of vertebral bodies trabecular bone density is accompanied by an increase in density of the outer layer of spine.
We hypothesize that S2 bone density is inferior to that of S1, increasing the chances of screw loosening and fixation failure despite screw placement consistent with accepted methods in the literature.
