A surgical reamer (10) for cutting a bone socket is provided, defining a drive axis, an apex. The reamer (10) further includes (a) a fixed support portion (12) aligned with the drive axis and having at least one radial cutting blade (16c); (b) a pivoting portion (20) aligned with the drive axis and pivotable about this axis, the pivoting portion supporting at least one radial cutting blade (20c); and (c) a pivoting joint (22) wherein the pivoting portion may be pivoted toward and away from the fixed portion (12) so as to expand or contract the reamer in relative overall size and wherein the reamer has a cutting orientation in which the cutting blades (16c, 20c) are supported against relative rotational movement when cutting bone. A surgical kit and method employing the inventive reamer are also disclosed.
