喙突内外径及前后径与关节盂宽度的关系

Relation between the mediolateral diameter and anterior-posterior distance of the coracoid process and the breadth of the glenoid cavity

目的:测定喙突内外径和前后径以及关节盂最大前后距离(关节盂宽度),探究喙突内外径及前后径与关节盂宽度在数值上的关系,为用喙突重建关节盂骨质缺损提供解剖学数据。方法:对成年肩胛骨的喙突最大内外径、最大前后径和关节盂宽度进行测量,然后分析其相关性。结果:关节盂宽度为(26.96±4.17)mm,喙突内外径为(14.87±3.38)mm,喙突内外径是关节盂宽度的55%±6%,相关性分析显示,两者具有相关性。喙突前后径为(9.71±3.27)mm,与关节盂宽度无相关性。结论:喙突内外径和关节盂宽度有相关性,提示喙突内外径越大,关节盂宽度也越大。这为用喙突重建复发性肩关节脱臼导致的关节盂骨质缺损提供解剖学数据。

Objective： To measure mediolateral （M-L） and antero-posterior （A-P） diameter of the coracoid process as well as the widest anterior-posterior distance of the glenoid cavity （glenoid cavity breadth） and to provide anatomical data for reconstructing the bone defect of the glenoid cavity with the coracoid process. Methods： The M-L diameter and A-P diameter of the coracoid process and the glenoid cavity breadth of 74 unpaired adult human cadaveric scapulae were measured to analyze their statistical relationship. Results： The breadth of the glenoid cavity was （26.96±4.17） mm and the M-L diameter of the coracoid cavity was （14. 87±3.38） mm. The coracoid process accounted for 49% to 61% breadth of the glenoid cavity （55% ±6%）. and there was obvious correlation between them. The A-P diameter of the coraeoid process was （9.71±3.27） mm, but A-P diameter of the eoracoid process was not correlated with the breadth breadth cavity. Conclusion： There is a linear relationship between M-L diameter of the coracoid process and the A-P breadth of the glenoid cavity. The larger the A-P and M-L diameter of the coracoid process, the larger the breadth of the glenoid cavity. It provides anatomical data for reconstructing recurrent shoulder bone defects of the glenoid cavity with the coronoid process.
