摘要: A bone cement plug for fitting into the intramedullary canal within a bone to restrict flow of bone cement during surgery comprises a sleeve (2) whose wall is circumferentially continuous and has an outer surface (10) for contacting the wall (32) of the canal. The sleeve (2) is formed from a deformable material so that it can be expanded transversely to contact the surface (32) of the canal. The plug includes an expander which can be drawn through the cavity (12) in a direction generally along the axis of the sleeve (2), to cause the sleeve (2) to expand transversely to contact the surface (32) of the canal. The inner surfaces of the wall converge towards the end (16) of the sleeve (2) towards which the expander is drawn to cause the sleeve (2) to expand to contact the surface (32) of the canal.

摘要: An assembly for use in fixing a first component of a joint prosthesis, having a bone facing surface and an exposed surface which faces towards a second component of the joint prosthesis when implanted on a patient's bone. The assembly includes a skirt which can be temporarily fixed to the edge of the first component extending along the edge thereof from a remote portion of the edge to an accessible portion of the edge. The skirt provides at least one opening through which cement located between the bone facing surface of the component and the surface of the bone can be displaced. The opening is located so that cement is prevented from being displaced at the remote portion of the edge and is instead displaced at the accessible portion of the edge.

摘要: An instrument for controlling the distribution of bone cement on the surface of the head of a bone to prepare the bone to receive a re-surfacing prosthesis comprises a hollow shell which can be fitted on to the head of the bone to define a space around the head. The shell is rotationally symmetrical and has a spike like projection extending axially from the internal surface of the shell. At least one rib is located on the internal surface of the shell, extending from the spike like projection or from close to it, towards the open face of the shell, which contacts cement on the head of the bone in a sweeping action when the shell is rotated around its axis on the head of the bone.
