1. A patient-specific guiding system for guiding an instrument relative to a portion of an anatomical feature of a patient, the patient-specific guiding system comprising:

  • a patient-specific guide having;

    a first portion having a first patient-specific inner surface that is configured to conform to and mate with a first surface of the anatomical feature in only one position and an outer surface opposite the first patient-specific inner surface, the first portion including a guide surface for use in guiding the instrument relative to the anatomical feature and a fixation feature for coupling the first portion to the first surface of the anatomical feature; and

    a second portion having a second patient-specific inner surface that is configured to conform to and mate with a second surface of the anatomical feature in only one position and an outer surface opposite the second patient-specific inner surface, the second portion being removably connected to the first portion;

    wherein the first and second patient-specific inner surfaces each have a three dimensional contour that is configured to nest and closely conform to the first and second surfaces, respectively, of the anatomical features, to align the guide relative to the anatomical feature; and

    wherein the first and second portions are non-adjustably conformable with the first and second surfaces when the first and second portions are connected to each other to facilitate engagement in a single desired orientation; and

    wherein the guide surface is an opening in the first patient-specific inner surface that is configured to receive the instrument.
