摘要:
A femoral trialling kit and method for assessing acetabular cup orientation during a left hip joint surgical procedure and a right hip joint surgical procedure are described. The kit includes a trial femoral head (104, 414, 514, 614, 814) having an inner wall defining a cavity extending along a head axis and a visual alignment guide on an outer surface of the trial femoral head and a trial femoral neck (126, 412, 512, 612, 812) having a taper at a free end, the taper being receivable within the cavity. One of the taper and the inner wall has a first anti-rotation feature (684, 698) and a second anti-rotation feature (686, 700), the first anti-rotation feature and the second anti-rotation feature being inclined, and the other of the taper and the inner wall has a third anti-rotation feature (702). The trial femoral head is attachable to the trial femoral neck in a first angular configuration corresponding to a right hip joint, in which the third anti-rotation feature and the first anti-rotation feature engage, and a second angular configuration corresponding to a left hip joint, wherein the third anti-rotation feature and the second anti-rotation feature engage.
