57 kDa PS; 25 kDa PMMA; m ~494; n ~520 PS Mn = 57 ± 6 kg/mol PMMA Mn = 25 ± 3 kg/mol PDI of the overall block copolymer <1.2 PS molecular weight verified by SEC (taking an aliquot from the reaction mixture) and the PMMA molecular weight by NMR spectroscopy. The overall block copolymer molecular weight distribution would be determined by SEC.

The outcome of a cemented hip arthroplasty is partly dependent on the type of cement which is used. The production of an interface gap between the stem and the cement mantle as a result of shrinkage of the cement, may
In a cadaver study, we prepared 29 paired human cadaver femora using 3 different broaches of identical geometry but different surface characteristics. In one group of 20 pairs, preparation with chipped-toothed broaches was compared to diamond-shaped broaches; in the other
