Abstract: The present invention includes a measurement/assessment technique based upon a collection of angular and distance measurements taken with respect to x-ray visible osteo-anatomical artifacts to arrive at accurate and easily reproducible component placement. In the context of hip arthroplasty surgery the method of the present invention involves determinations, from two different two-dimensional views, of the angles and distances from osteo-anatomical artifacts, to allow a surgeon to approach a hip resurfacing operation with the distance and angular measurements to be translated into actual markings and device settings to be able to accurately ream the femoral head structure, position and affix the femoral cap and acetabular cup components in accordance with the pre-determined distance and angular measurements.
