Acrylic resin, which is harmiess to the living body and unchangeable in the on account of its superior physical, chemical, and mechanical characteristics, is now widely appslied in the various fields of clinics. But this resin has the disadvantages being fusible at rather low er degree of the heat and difficult to be sterilised.I made the Judet's artificial femoral head of acrylic resin in accordance with the general method by which a tooth-plate is made, using as its material polymethyl-metacrylate made in our country. The point to which I had to pay the most careful attention in the making of this artificial femoral head was how to cure the material and get best article having no foam in it. For this purpose, I at first boiled the material untill the heat of 70°C spending about an hour, and then kept it being boiled at the same heat for an hour and at the heat of 100°C for the same hour respectively; spending three hours in all.The femoral head of my own device has 8 holes of 0.3cm diametre at its rin, by which its fixation can be strengthened.
