<p>A device for determining possible impingement of a replacement tissue graft with a portion of a bone at a joint, the replacement tissue graft of the type to be inserted and secured within a bone passage at the joint. The device includes (1) an elongated support shaft having a longitudinal axis and (2) a head disposed at a distal end of the support shaft. The head has (a) an engagement passage having an axis, the engagement passage configured to engage a guide wire disposed within the bone; and (b) an impingement surface corresponding to the shape of a portion of the replacement tissue graft, the impingement surface spaced from the axis of the groove by a pre-determined distance corresponding to a dimension of the tissue graft.</p> |
