A surgical alignment guide for hip replacement or revision surgery includes a support (12) for a prosthetic acetabular cup, the support being connected to one end of a carrier shaft (10). The support (12) has a bore (14) angled relative to the shaft so that a prosthetic acetabular cup secured to the support (12) has the correct orientation. An arm (26) extends from the shaft (10) at a position spaced from the support (12), and an adjustment arrangement (17, 21) is associated with the shaft (10) to enable adjustment of the angular position of the bore (14) with respect to the arm (26). In one form, an outer end of the arm (26) is connected to a gauge (28) which provides an alignment orientation indication of the cup support (12) and a prosthetic acetabular cup attached thereto. The adjustment arrangement may have two radial fingers (17) extending from the shaft (10) and engagable with teeth (24) associated with the arm (26). |
