Correlation between ultrasound velocity and densitometry in fresh and demineralized cortical bone.

Objective:: To compare ultrasound propagation velocity with densitometry in the diaphyseal compact cortical bone of whole sheep metatarsals.

Methods:: The transverse ultrasound velocity and bone mineral density of 5-cm-long diaphyseal bone segments were first measured. The bone segments were then divided into four groups of 15 segments each and demineralized in an aqueous 0.

Morphological evaluation of eccentric sets guide-plates of dcp-l 4.5 mm.

Objective: To carry out isolated and comparative evaluations of the measurements of the set eccentric guide plates used in 4.5mm surgical implants, and to determine the effect of these measurements on compression strength.

Methods: Four eccentric guides, four large dynamic compression plates (L-DCP) from four local manufacturers, and a Vonder(®) 200 mm caliper brand were used.
