A bent trial femoral neck (400) and method for visually assessing the orientation of an acetabular cup implanted in a pelvis of a patient are described. The bent trial femoral neck comprises a body (402) extending along a femoral neck axis, an attachment formation (408, 410) extending from the body for releasably attaching the trial femoral neck to a femoral part received with a femur of the patient and a taper (404). The taper extends along a taper axis and the taper axis is tilted anteriorly relative to the femoral neck axis by an angle configured to position a trial femoral head having an indicium on an outer surface so that the indicium is parallel to a plane of a rim of the acetabular cup, or a rim of a liner within the acetabular cup, when the acetabular cup is oriented in the pelvis of the patient with a target orientation and the hip joint is in a predetermined position.
