Abstract
An instrument for guide pin placement in a femoral head and neck of a patient, the instrument having a reference pin guide member and a retrograde pin guide member adjustably attached to the reference pin guide member. The reference pin guide member has a bore configured for use in positioning and guiding an external reference pin. The retrograde pin guide member has a plurality of retrograde pin bores for use in positioning and guiding a retrograde reference pin into the femoral neck and head of the patient using a retrograde approach. If an initial retrograde reference pin is not positioned properly, one of the plurality of retrograde pin bores is used to insert another retrograde reference pin in a more desirable position using a retrograde approach.
