Abstract:
1. An instrument for aligning a cut guide in a particular angular arrangement with respect to a bone, the bone extending between a distal end and a proximal end, the instrument comprising: a body having a proximal body end, a distal body end and a body longitudinal axis, the distal body end adapted to be fixed to the distal end of the bone, the body including a coupling shaft; a coupling head pivotably coupled to the coupling shaft, the coupling head pivotable about a pivot axis; a spring disposed between the coupling head and the coupling shaft, the spring biasing the coupling head against rotation with respect to the coupling shaft; a fixation arm comprising: a cut guide coupled to the body, the cut guide defining a fixed angular orientation with respect to the body, the cut guide defining a variable angular orientation with respect to the fixation arm.
