Fig. 4From: Reconstruction of recurrent shoulder dislocation with glenoid bone defect with 3D-printed titanium alloy pad: outcomes at 2-year minimum follow-up3D printed pad mock-up installation. (A) A Kirschner wire was inserted into the middle guide hole of the 3D-printed guide plate. (B) The 4.5Â mm hollow drill was used to enlarge the bone channel. (C) The central column of the pad is driven into the shoulder glenoid through the bone channel. (D) Simulation drawing of 3D printing pad after installationBack to article page
