Fig. 3From: The study of screw placement parameters for Ogawa type I acromial fractures by 3D simulationObserve the largest length and position of the screws. A, B Observed from the above and below of the opaque 3D model, respectively. The screws had the largest lengths and diameters just penetrating the cortical bone. a, b The screws position were observed from the above and below of the translucent 3D model.Back to article page
