Abstract
An acetabular prosthesis for use in an artificial hip joint. Because acetabula vary in size, it is not practicable to produce a single prosthesis for each acetabulum, being preferable to provide a blank which can be manually trimmed to fit each acetabulum. Here a blank is used in the formation of an acetabular prosthesis comprising a body surrounding and defining a part-spherical socket whose entrance is surrounded by an annular rim and having a flange extending outwardly and rearwardly from the periphery of the rim and made of a material capable of being manually trimmed to be asymmetrical. The flange may be marked with cutting lines to indicate where it should be trimmed to fit a left or right acetabulum.
