1. A surgical instrument system for treatment of an anatomical structure comprising a first patient specific instrument and a second patient specific instrument, each configured to be attached to the anatomical structure, and an instrument for performing the treatment on the anatomical structure, wherein the first patient specific instrument and the second patient specific instrument are configured as patient matched devices to directly register the anatomical structure of a patient's anatomy comprising a first anatomical structure and a second anatomical structure, wherein the first patient specific instrument is configured to be attached to the first anatomical structure, and wherein the second patient specific instrument is configured to be attached to the second anatomical structure, wherein the first patient specific instrument comprises an integrated measurement system to track a position of the second anatomical structure relative to the first anatomical structure, wherein the integrated measurement system is also configured to track the instrument, and wherein the second patient specific instrument comprises a light source, wherein the integrated measurement system comprises a patient specific instrument sensor, such that a first patient specific instrument position information is obtainable, wherein the patient specific instrument sensor comprises an imaging device and wherein a shadow-generating device is arranged between the light source and the imaging device, wherein the integrated measurement system is configured to compute an elevation of the light source from a pattern cast by a shadow generated by the shadow-generating device on a surface of the imaging device in response to light from the light source being projected onto the shadow-generating device, and wherein an initial position of one of the first patient specific instrument or second patient specific instrument is registerable by the patient specific instrument sensor in a three-dimensional coordinate system such that the position of the second anatomical structure is obtainable.
