Design of patient-specific instrumentation device to fit glenoid face. The glenoid guide is designed to perfectly reflect each glenoid's morphology. Green arrow is y axis and red arrow is x axis in two-dimensional space. Yellow shape displays the outline of the patient-specific instrumentation guide. Blue displays a portion of a circle drawn using the origin of x and y axes as the center. The completed hollow cylinder (bottom right) directs placement of the central guide pin in the desired trajectory.
