Abstract
A reamer comprises a handle, a first shaft extending from the handle in a fixed manner, first and second pivoting blades connected to a distal end of the first shaft, a second shaft extending from the handle in a translatable manner, wherein the handle is rotatable to adjust a position between the first and second shafts to adjust a cutting diameter of the pivoting blades, and a locking mechanism to lock the pivoting blades into different cutting diameters. The pivoting blades can comprise double-sided blades. A method of reaming a bone with an expandable reamer comprises adjusting a cutting diameter of a cutting tip to a first diameter, locking the cutting tip at the first diameter, reaming a first diameter bore into the bone, unlocking the cutting tip, expanding the cutting diameter to a second diameter, relocking the cutting tip, and expanding the first diameter bore.
