Abstract 1446097 Moulding bone prosthesis CERAUER 9 Jan 1974 [18 Jan 1973] 01121/74 Heading B5A [Also in Division A5] In a method of manufacturing a bone prosthesis, a porous bone contacting part thereof is formed by heating ceramic grains having dimensions of at least 0À5 mm. to a temperature lower than their sintering temperature, crushing the grains after cooling, subjecting the grains together with a binder to a pressure of at least 1 ton/sq. cm. to form a unitary mass and sintering the mass. The porosity of the bone contacting part may be 30%, and the pore dimension between 100-200 microns. The prosthesis may comprise a part 1 fixed to a hip 2, and a part 3 fixed to a thigh bone 4. The part 7 contacting the hip bone is produced in the manner described and is secured to a part 5 of compact sintered alumina with a polished surface 6. The part 3 includes a metallic rod portion 12 with pieces 13 produced as described.
