ABSTRACT:
A laser diffraction apparatus for measuring muscle sarcomere length IN VIVO, primarily useful for tendon transfer procedures, includes a screen and laser assembly adapted to direct a laser beam through a muscle tissue supported by a 180.degree. deflection prism towards the screen which receives the resultant diffraction pattern. This diffraction pattern determines the length of the muscle's sarcomere. A mechanism is provided for adjustably positioning the laser assembly and the 180.degree. deflection muscle tissue supporting prism relative to the operative field.
