Fig. 4From: A guideline for screw fixation of coracoid process base fracture by 3D simulationThe measurement of distance L1, L2, L3 and L4. The yellow outline represents the boundary of the horizontal part of the coracoid process. The distances from the medial and lateral screw insertion points to the closest point of the coracoid were recorded as distance L1 and L3, respectively. The vertical distances from the medial and lateral screw insertion points to the posterior border line of the horizontal part of the coracoid were recorded as distance L2 and L4, respectivelyBack to article page
