Fig. 3From: A large animal model for standardized testing of bone regeneration strategiesa Definition of the measurements for the characterisation of the anatomical properties of the experimental site in the shoulder blade of sheep: Total height of the medial bulge (1), cortical thickness of the medial wall (2), cortical thickness of the lateral wall (3), width of the medial bulge (4), minimal necessary distance from caudal margin (5), height of experimental space (6). The experimental space in which the defect should be placed to achieve controlled and reliable results is marked by a green inlay. b Cranially displaced drill hole breached both cortical walls. c Caudally displaced drill hole located too close to the caudal cortical wallBack to article page
