Abstract

The invention provides an impactor for transmitting an assembly force to a component of an orthopaedic implant. The impactor has first and second telescoping parts which are biased apart by means of a main spring. The main spring is compressed when an assembly force is applied to the parts. An indicator is latched against movement until it is released when the extent of the compression of the main spring by the application of an assembly force exceeds a threshold. The indicator then moves to provide the user with an indication that a minimum assembly force has been applied.
