An orthopaedic assembly includes a first portion or an acetabular cup and a second connecting portion or a cup inserter. The acetabular cup includes a cavity for receiving a femoral head and a pole defining a longitudinal axis through the cavity. The acetabular cup further includes an annular face which bounds the cavity and has a plurality of notches extending therein. Each notch includes an undercut wall. The annular face further includes a projection receiving device. A cup inserter includes a body with an end face and a plurality of fingers extending from the end face. Each finger is insertable into a corresponding one of the notches in a direction parallel to the longitudinal axis and is rotatable around the longitudinal axis to a locking position. Each finger includes a transverse surface which matingly engages with a corresponding one of the undercut walls when the finger is in the locking position. The cup inserter further includes a projection and a biasing device. The projection is slidably carried within the body and is movable between a retracted position and an extended position. The biasing device biases the projection toward the extended position. The projection is biased to the extended position and received within the projection receiving device of the cup when each finger is in the locking position.
