摘要： A femoral stem including a stem member having a distal part of the stem member which is inserted in a medullary cavity of a femur and fixed therein and a proximal part of the stem member which has a neck for fixing an artificial head and is positioned at a proximal end of the distal part. The distal part and the proximal part are integrated or separable. Also, a plate fixing portion is detachably attached at a top of the proximal part, and a greater trochanter plate is provided for depressing the greater trochanter. The greater trochanter is fixed to the plate fixing portion at a certain angle or is fixed to the plate fixing portion so as to adjust an angle of the trochanter plate.

摘要： Alkyl 4,4'-(ethylenedioxy)bis-benzoates having improved properties such as anti-oxidation and anti-coloration are prepared in high yield and selectivity by, at the first step, reacting an excess alkyl p-hydroxybenzoate with a recycling alkyl p-(2-chloro-ethoxy)benzoate with heating in the presence of an alkali carbonate and an inert organic solvent until almost said alkyl p-(2-chloroethoxy)benzoate is consumed to produce an alkyl 4,4'-(ethylenedioxy)bis-benzoate and at the second step adding ethylene dichloride to the reaction system and continuing the heating to produce an alkyl p-(2-chloroethoxy)benzoate which is recycled, and separating the alkyl 4,4'-(ethylenedioxy)bis-benzoate produced.
