[Abstract]:Objective: to study the anatomical characteristics of coracoid and articular pelvis and the relationship between them by CT 3D reconstruction data and Mimcs software reconstruction technique, and to provide anatomical data of coracoid process and glenoid structure for arthrologists. To guide the clinical application of Bristow-Lartarjet coracoid process transposition osteotomy. Methods: 61 cases (35 males and 26 females), aged 48.7 years, were collected from 61 patients (35 males and 26 females) from January 1 to June 2016.The imaging data were obtained from 61 patients who needed 3D CT reconstruction of shoulder joint because of their condition. The DICM format data were imported into Mimcs software to reconstruct the coracoid process model. The total length of coracoid process, the width and height of 1.5cm below the tip of coracoid process, the distance between coracoid tip and middle point of coracoid process, the width and height of middle point of coracoid process, the maximum anteroposterior diameter of scapula glenoid were measured by computer software, and the measured data were collected. The ratio of width and height of 1.5cm to the maximum anteroposterior diameter of scapular glenoid was calculated to guide the application of Bristow-Lartarjet operation. Results: in 61 cases of coracoid process reconstruction model, The average width of 1.5cm below the coracoid process is 13.45 鹵2.19mm.The average height of 1.5cm below the coracoid process is 9.27 鹵1.84mm4 and the average distance from the coracoid process to the middle point of the coracoid process is 20.83 鹵2.16mm.The average width of the middle point of the coracoid process is 15.48 鹵1.69mm. The average height of the midpoint of the tip was 11.60 鹵1.97mm, the width of 1.5cm below the coracoid process was 26.58 鹵1.92mm, the distance between the maximum anterior and posterior diameters of the articular pelvis was 26.58 鹵1.92mm. The ratio of height to maximum anteroposterior diameter of scapular pelvis was 35% (25-43%) and 51% (39-66%) respectively. The cross-sectional height of coracoid process 1.5cm was 9.27 鹵1.84 mm, in which the inner diameter of cancellous bone was 5.56 鹵0.92 mm, the thickness of unilateral cortical bone was 1.85 鹵0.13 mm, and the thickness of unilateral cortical bone was about 20 mm. The average width of 1.5cm below coracoid tip was 13.45 鹵2.19 mm, in which the diameter of cancellous bone was 8.61 鹵1.74 mm, the thickness of unilateral cortical bone was 2.42 鹵0.18 mm, and the thickness of unilateral cortical bone was 2.42 鹵0.18 mm. The thickness of bone is about 18% of the cross section. Conclusion: there is a significant linear positive correlation between the width and thickness of the coracoid process and the maximum anteroposterior diameter of the articular pelvis. With the increase of the maximum distance between the anterior and posterior diameter of the articular pelvis, the width and height of the coracoid process tip are also larger. When coracoid bone was taken to repair the defect of anterior glenoid bone, the proper operation method should be selected according to the actual injury.
