Claim:
1. A surgical planing instrument with an adjustable profile, the planing instrument comprising: a rotatable cutting head comprising a proximal end, a distal end and an axis of rotation about which the cutting head is rotatable; a cutting face positioned on the distal end of the cutting head, the cutting face conforming to a plane extending generally perpendicular to the axis of rotation; at least one radially displaceable cutting element having a cutting edge, the cutting edge projecting in a distal direction from the cutting face; a generally cylindrical collar located substantially adjacent to the at least one radially displaceable cutting element, the collar located in the center of the cutting face and defining a centering mechanism; and an adjustment element operably engaged with the at least one radially displaceable cutting element, the adjustment element being operable in a first operation to displace the at least one radially displaceable cutting element radially inwardly with respect to the axis of rotation, and toward a fully retracted state in which the cutting head has a minimum cutting head profile, the adjustment element also being operable in a second operation to displace the at least one radially displaceable cutting element radially outwardly with respect to the axis of rotation, and toward a fully expanded state in which the cutting head has a maximum cutting head profile.
