Journal ArticleDOI
Predicting the compressive mechanical behavior of bone
TL;DR: The results indicate that the mathematical dependency of bone compressive mechanical properties on composition is closely dependent upon the density and mineral content range examined and, in terms of a single compositional measure, is best predicted by apparent ash density expressed as a power function.
Journal ArticleDOI
Relationship between vertical ground reaction force and speed during walking, slow jogging, and running
TL;DR: The results suggest that vertical GRF norms can be established for male and female subjects alike, and that slow or fast running with a lower, fixed centre of gravity decreases impact forces.
Journal ArticleDOI
The influence of bone volume fraction and ash fraction on bone strength and modulus.
Christopher J. Hernandez,Christopher J. Hernandez,Gary S. Beaupre,Gary S. Beaupre,Tony S. Keller,Dennis R. Carter,Dennis R. Carter +6 more
TL;DR: The exponent related to ash fraction was typically larger than that associated with bone volume fraction, suggesting that a change in mineral content will, in general, generate a larger change in bone strength and stiffness than a similar change inBone volume fraction.
Journal ArticleDOI
Porous ceramics as bone graft substitutes in long bone defects: a biomechanical, histological, and radiographic analysis.
Kenneth D. Johnson,Kerek E. Frierson,Tony S. Keller,Charles Cook,Robert Scheinberg,Joseph E. Zerwekh,Laura Meyers,Marcus F. Sciadini +7 more
TL;DR: Biomechanical testing and radiographic evauation revealed that the addition of bone marrow aspirate was essential for tricalcium phosphate and hydroxyapatite to achieve results comparable with those of cancellous bone, and this degradation took place only after a degree of mechanical competence necessary for weight‐bearing was achieved.
Journal ArticleDOI
Influence of spine morphology on intervertebral disc loads and stresses in asymptomatic adults: implications for the ideal spine.
TL;DR: It is suggested that sagittal spine balance and curvature are important parameters for postural load balance in healthy male and female subjects.
