摘要: An acetabular reaming system is disclosed of the type having a driver and a tool held together by a quick-release coupling mechanism. The tool (10) has a hollow body (12) defining a domed shape with a rotational axis (14), an apex (16) aligned with the axis (14) and a hemispherical wall (18) extending from the apex (16) to an equatorial rim (20) spaced 90 degrees from the axis (14). The rim (20) has an edge (22) visible to the user that indicates the position of the tool (10) relative to the bone. A first plurality of cutting sites (24) is arrayed along the body (12) and a second plurality of cutting sites (28) is arrayed circumferentially along the edge (22). Preferably, the first plurality of cutting sites (24) present raised first teeth (30, 130, 230, 330) having a profile selected from continuous squared (30), continuous rounded (130), discontinuous squared (230) and tongued (330) profiles. Also preferably, the second plurality of cutting sites (28) present raised second teeth (32, 132, 232, 332, 432) selected from continuous squared (32), continuous rounded (132), discontinuous squared (232), tongued (332) and bladed (432) profiles.
