Abstract:
An orthopedic instrument system for reaming a long bone comprising:a fixed length elongate reamer having a proximal portion, a bone contacting outer surface, at least one bone cutting element integral with the bone contacting outer surface, and a single stop engaging element disposed thereon; anda stop indicating sleeve comprising a substantially cylindrical sleeve defining an axial bore, the sleeve being removably disposed about the elongate reamer and having a bone contacting distal end and a stop element, the stop element being selectively movable between a first, disengaged position in which the stop element does not engage the stop engaging element on the reamer, and a second, engaged position wherein the stop element engages the stop engaging element to prevent proximal motion of the stop indicating sleeve relative to the reamer;wherein the stop element is biased to the second, engaged position; andwherein, at a predetermined reaming depth, the bone contacting distal end of the sleeve contacts a portion of the long bone not reamed by the elongate reamer and the stop element on the sleeve engages the stop engaging element disposed on the reamer to prevent the reamer from reaming the long bone further than the predetermined reaming depth.
