To quantify the size and angle of the medial and lateral facets of the ulnar coronoid process by reformatted computed tomography (CT) imaging.
Elbow CT images were retrospectively selected from the picture archiving and communication system in our hospital over a 5-year period (January 2011 to December 2015). The widths, heights, gradient and tilt angles of both the medial and lateral facet of the ulnar coronoid process were measured using two-dimensional (2D) reformations of CT images.
Our database research yielded 120 elbow joints (53 right, 67 left) of 120 patients (54 males, 66 females) which fulfilled our criteria. The average width of the two facets of the ulnar coronoid process were 13.34±1.85 mm for the medial facet and 8.39±1.29 mm for the lateral facet. The average height of the medial facet was 18.45±3.38 mm and the lateral facet was 17.55±3.81 mm. The average tilt angles of medial and lateral facet were 80.34°±7.71° and 98.78°±5.71° respectively. The average gradient angles of the medial and lateral facet ridge were 60.02°±8.78° and 36.97°±4.99° respectively. The length of the lateral facet ridge was longer than the medial facet ridge.
Reformatted CT images allow for multiple, accurate measurements of facets on the ulnar coronoid process. These measurements can be applied to guiding appropriate surgical interventions for fractures in this area.
通过重组计算机断层扫描（CT）成像来量化尺骨冠突内侧和外侧小关节面的大小和角度。
回顾性选取我院图片存档与通信系统中5年期间（2011年1月至2015年12月）的肘部CT图像。使用CT图像的二维（2D）重组测量尺骨冠突内侧和外侧小关节面的宽度、高度、倾斜度和倾斜角度。
我们的数据库研究得到了符合标准的120例患者（54例男性，66例女性）的120个肘关节（53个右侧，67个左侧）。尺骨冠突两个小关节面的平均宽度，内侧小关节面为13.34±1.85毫米，外侧小关节面为8.39±1.29毫米。内侧小关节面的平均高度为18.45±3.38毫米，外侧小关节面为17.55±3.81毫米。内侧和外侧小关节面的平均倾斜角度分别为80.34°±7.71°和98.78°±5.71°。内侧和外侧小关节面嵴的平均倾斜角度分别为60.02°±8.78°和36.97°±4.99°。外侧小关节面嵴的长度比内侧小关节面嵴长。
重组CT图像能够对尺骨冠突上的小关节面进行多次准确测量。这些测量结果可用于指导该区域骨折的适当手术干预。
