Abstract
The invention is directed to an orthopaedic template system for use with a bone (14) having a shaft and a bearing surface at an end of the shaft. A first template (30) is attachable to the bone end adjacent to the bearing surface, and includes a first saw guide surface or slot (40). A joint locator (10) is used to position the first template (30) relative to the bearing surface. A second template (50) is pivotally attachable to the first template (30), whereby the second template (50) may be selectively positioned at one of a plurality of angular orientations relative to the first template. A third template (70) includes a second saw guide surface or slot (78), and is attachable to the first template (30) at a plurality of locations (72, 74, 76), whereby the second saw guide slot (78) may be selectively positioned relative to the first saw guide slot (40).
