Fig. 1From: Evaluation of the inter and intraobserver reproducibility of the “defect coverage index method”, a new computed tomography assessment method of sagittal graft positioning in arthroscopic bone block proceduresa CT en-face image of the left shoulder of a subject with anterior shoulder instability and apparent anterior glenoid bone loss. The glenoid bone defect is measured using the PICO method. A best-fit circle is drawn around the posteroinferior cortical margin of the glenoid. The defect is manually drawn and measured using the area toolBack to article page
