3D Printed Anatomy-Specific Fixture for Consistent Glenoid Cavity Position in Shoulder Simulator

Figure 1

Glenoid cavity centroid: (a) the bearing surface is defined by a plane that rests on the three most distal vertices; (b) a circle is fitted to the defined bearing surface; (c) the normal distance is measured from the circle centroid to glenoid cavity surface; (d) the glenoid cavity centroid is then calculated.
