Methods for inhibiting sensory responses in the skin such as pain and itch using topical formulations containing aqueous-soluble divalent strontium cation in a suitable topical keratinized skin formulation vehicle are disclosed. The kit comprises one shape wire, two side wires, one shape sheet and one domed support pad. The total internal reflection of the laserincident light is collected with a differential position or intensity sensitive photo-detecting device instead of a single cell or an array of photo-detectors that are widely used in previous works. A third resection guide is mounted on the third surface of the first resection guide and extends in a medial-lateral direction therefrom across at least part of the resected distal femoral surface. The display in which an icon is located can be rearranged as a result of the icon being resized.
