Method of using a guide-pin placement device

A method of placing an orthopedic instrument in a desired position relative to a bony target using an imaging device;

• providing a housing with a guide passageway through which said instrument is passed;
• providing at least one targeting arm member fixed to said housing, said targeting member containing at least one relatively radio-opaque target marker that establishes a plane that is co-planar with an axis of said passageway;
• manipulating said targeting arm member until the plane established by the targeting arm member is co-planar with a beam from an imaging device and a desired location or trajectory relative to a bony target in one view;
• moving the targeting arm and the imaging device so that they are oriented in an orthogonal position with respect to their co-planar position and manipulating said targeting member until the plane established by the targeting arm member is co-planar with a beam from said imaging device and a desired location or trajectory relative to a bony target;
• and
• passing said instrument through said passageway.
