Abstract
A seal member for fitting over and sealing the opening of a cavity in a bone to allow pressurization of cement in the cavity has an aperture for sealingly receiving a cement delivery nozzle. The seal member may be a balloon seal, which may be inflatable and expandable, or a solid body of conformable material. In use, the seal member is urged against the opening, e.g. by force applied by the barrel of a cement delivery gun on an abutment means having an apertured pressure piece shaped to urge the seal member against the mouth of the opening.
