Abstract: A surgical jig and method of use in image guided and non-guided surgery are described. The jig is for use in determining an axis of a body part. The jig includes a handle at a proximal end and a mouth at a distal end. The mouth is engagable about the body part and defines a substantially flat plane. A guide has a channel with an axis substantially perpendicular to the plane and a support attaches the guide to the jig. The guide can be translatable relative to the mouth while maintaining the axis substantially perpendicular to the plane. The method determines an axis relative to a body part using the jig. The method comprises engaging the mouth about the body part and translating the guide relative to the mouth so as to align the axis of the channel with the axis of the body part.

Abstract: A drill guide assembly for determining the axis for drilling a bore in a generally dome-shaped bone to receive a component of an orthopaedic joint prosthesis is described. The drill guide assembly includes a drill guide sleeve, a carriage and a platform. The drill guide sleeve is mounted in the carriage towards a first end so that the angular orientation of the drill guide sleeve relative to the carriage can be adjusted about at least one axis. The carriage includes at least one threaded angle-adjustment screw which extends between the carriage and the drill guide sleeve by which the angular orientation of the drill guide sleeve can be adjusted. The platform is fastenable to the bone, and includes at least three feet depending from the platform to engage the surface of the bone with the bone extending towards the platform into the space between the feet.
