Fig. 2From: 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 postoperative CT en-face image of the left shoulder of a subject with anterior shoulder instability following an arthroscopic bone block procedure. The bone-block position is evaluated using the “Defect coverage index method”. First the length of the bone defect is measured (green line, B) (A). Secondly, the amount of graft covering the glenoid defect is quantifiedBack to article page
