摘要/Abstract

摘要： 目的探讨CT三维重建的肩胛骨关节盂形态学特点及其临床意义。方法搜集290例关节盂三维重建影像资料，观察关节盂形态特点，测量关节盂上下径、前后径及关节盂窝深度，关节盂倾斜角、扭转角的度数。结果 CT三维重建图像显示，肩胛骨关节盂大致有4种类型：引号型56.90%（165例）、椭圆型22.41%（65例）、水滴型17.59%（51例）、葫芦型3.10%（9例）。椭圆型的关节盂上下径、盂窝深度及关节盂倾斜角、扭转角与引号型、水滴型及葫芦型有统计学差异；水滴型的关节盂倾斜角大于引号型；葫芦型的关节盂上下径小于引号型及水滴型；椭圆型及水滴型的关节盂前后径长于引号型及葫芦型；引号型的关节盂前后径长于葫芦型；引号型的关节盂窝深度小于水滴型及葫芦型；关节盂上下径、前后径、关节盂窝深度、关节盂倾斜角，不同性别有统计学差异，以上差异均P<0.05。结论基于CT三维重建结果，肩胛骨关节盂可分为4个类型，以引号型为主，葫芦型少见，其形态学分型具有一定的临床指导意义。

Abstract: Objective　To explore the morphological classification and clinical significance of glenoid based on CT 3D reconstruction.　Methods　Data of 290 cases of scapular bones data were collected from People's Hospital of Lu Xian County. The morphological characteristics of the glenoid pelvis were observed, and the upper and lower diameters, anterior and posterior diameters of the glenoid pelvis, the depth of the glenoid fossa, the degree of tilt angle and torsion angle of the glenoid pelvis were measured. Results　The result of CT three- dimensional reconstruction showed that, the glenoid was classified into four types: namely, quotation marks-type (165 cases, accounting for 56.90%); oval-type(65 cases, accounting for 22.41%); water drops-type ( 51 cases, accounting for 17.59 %); gourd-type(9 cases, accounting for 3.10 %). There were statistical differences in the upper and lower diameters of the glenoid pelvis, the depth of the glenoid fossa, the degree of tilt angle and torsion angle of the glenoid pelvis between the oval-type and the quotation marks-type, water drops-type and gourd-type(P<0.05). The degree of tilt angle in water drops-type was greater than that of quotation marks-type. The upper and lower diameters of the glenoid pelvis in gourd-type were less than that of quotation marks-type and water drops-type. The anterior and posterior diameters of the glenoid pelvis in oval-type and water drops-type were greater than that of quotation marks-type and gourd-type. The anterior and posterior diameters of the glenoid pelvis in quotation marks-type was greater than that of gourd-type. The depth of the glenoid fossa in quotation marks-type was less than that of water drops-type and gourd-type. There were statistical differences in genders among the upper and lower diameters, anterior and posterior diameters of the glenoid pelvis, the depth of the glenoid fossa, the degree of tilt angle and torsion angle of the glenoid pelvis (all P<0.05).　Conclusions　Based on the results of three-dimensional CT reconstruction, the glenoid can be divided into four types, with the quotation marks-type as the main type and gourd-type as the rare type, and the morphology and classification of which are of certain clinical guiding significance.
