The mean stiffness of osteotomized specimens plated with unicortical locked fixation showed a decrease of 44% when compared to specimens plated with bicortical non-locked fixation (0.12 N⋅m per degree versus 0.21 N⋅m per degree, P<0.013).
Maximum torque at failure for unicortical locked fixation was 59% less than specimens plated with bicortical non-locked plate fixation (2.67 N⋅m versus 6.57 N⋅m, P<0.002).
Osteotomized specimens that were reconstructed using unicortical locked plates showed an average increased stiffness of 21% when compared to those specimens plated using bicortical fixation (185 N⋅mm−1 versus 153 N⋅mm−1, P<0.03).
Then, crush tests of a specimen (plate with ribs) made by rubber toughened polypropylene are carried out to prepare benchmark data.
Now that the completely preserved right side of the Messel specimen (plate A) is known and described herein, it is clear that Darwinius masillae n.gen., n.sp.sp
The Oslo specimen, plate A, clarifies exactly which parts of plate B were faked, including notably, hands and feet (where some proportions of constructions may have been based on reversed photos of A) and the tail vertebral column.
When Franzen described the counterpart specimen (plate B) and assigned it to Godinotia neglecta from Geiseltal [1], the permanent dentition of the Messel specimen was only represented by a fragmentary left M1 and an incomplete forelimb and lower leg without hands and feet.
Thirdly, the conversion formula of dynamic stability between cylindrical specimen and plate specimen was established according to the correlation between the test results of two kinds of specimens.
Extensometer measurements displayed a steady increase in the relative displacement between the specimen plates due to fatigue degradation of the bolt holes and the composite plates.
Specimen plates manufactured from a carbon fibre/epoxy material system were joined by fasteners of three different types: composite, titanium torque-set, and titanium Huck-comp.
