Abstract

Abstract: Objective　To investigate the anatomic morphology and clinical significance of the spinoglenoid notch based on dry scapular bones.　Methods　In a total of 282 scapular bones (left 134, right 148), the following data were measured using Vernier caliper and Goniometer: the width of spinoglenoid notch (the distance from medial aspect of the glenoid to the scapular), the thickness of the spinoglenoid notch (the thickness of the nadir of the spinoglenoid notch), the depth of spinoglenoid notch, the angles of the spinoglenoid notch. 　Results　The average width and depth of the spinoglenoid notch were (12.75±1.06) mm and (11.65±1.89) mm. There was statistical difference between the two sides of body (P<0.05). The average thickness of spinoglenoid notch was (9.93±1.57) mm. The distance from the spinoglenoid notch to the suprascapular notch was (18.73±3.18) mm (P>0.05). There was statistical difference of the angles of the spinoglenoid notch between the two sides of body (40.24±8.69) (P<0.05).　Conclusion　The width, thickness and depth of the spinoglenoid notch are all the risk factors contributing to the suprascapular nerve entrapment syndrome. The smaller the angles of the spinoglenoid notch, the greater the chance of scapular nerve compression. The data presented in this study can provide a reference for clinicians to choose the best surgical approach and the internal fixation site to reduce the risk of intraoperative nerve injury, thus minimizing intraoperative risks.
