Low viscosity bone cement is an acrylic cement-like substance which permits seating and securing of a prosthesis into living bone. It comprises a mixture of a liquid monomer component and a polymer powder component. It maintains a low viscosity for a longer period of time. This cement is intended for syringe or injector gun use only as it is to be used before the cement becomes doughy. It has a viscosity of approximately 20 degrees C., of less than 1500 poise, and preferably less than 1000 poise up to the sixth or seventh minute after the two components are mixed.
