摘要目的通过测量尺骨鹰嘴的影像学数据，为尺骨鹰嘴骨折张力带手术克氏针置入方向、角度及宽度提供理论参考。方法回顾性收集2020年9月至2020年12月我院60例成人正常肘关节正侧位X线片，其中男30例，女30例；男性平均年龄(37.63±13.75)岁，女性平均年龄(39.70±14.60)岁。分别测量并记录肘关节正位尺骨近端内翻角、鹰嘴最狭窄处宽度，肘关节侧位鹰嘴尖端过鹰嘴窝切线与尺骨轴线的夹角。结果尺骨近端内翻角男性平均为(10.71±2.77)°，女性平均(9.97±2.89)°，两组比较差异无统计学意义(P＝0.70)；男性鹰嘴最狭窄处宽度(1.90±0.96)mm，女性(1.61±0.12)mm，两组比较差异有统计学意义(P＝0.00)；鹰嘴尖端过鹰嘴窝切线与尺骨轴线的夹角男性平均(25.42±2.31)°，女性平均(23.12±2.64)°，两组比较差异无统计学意义(P＝0.10)。结论通过测量的尺骨鹰嘴影像学参数，为鹰嘴骨折张力带手术时克氏针进针方向、角度及宽度提供参考，提高手术准确度。

Abstract：Objective To provide a theoretical reference for tension band fixation of olecranon fractures by measuring the anatomical parameters of the ulna olecranon. Methods From September 2020 to December 2020，anteroposterior and lateral radiographs of the elbow were obtained for anatomic measurement in the retrospective study，including 30 males and 30 females.The mean age of males was (37.63±13.75)years，and that of females was (39.70±14.60)years.The following parameters were measured：the proximal ulna varus angle，the ulna olecranon width，and the angle between the tangent line of the olecranon fossa and ulna axis.Results The mean value for the proximal ulna varus angle was (10.71±2.77)°in males and (9.97±2.89)°in females，and no significant difference was observed between the two groups (P＝0.70).The widths of the ulna olecranon in men(1.90±0.96)mm were significantly larger than those of females (1.61±0.12)mm (P＝0.00).The angle between the tangent line of the olecranon fossa and the ulna axis was (25.42±2.31)° in males and (23.12±2.64)° in females，and no significant difference was seen between the two genders (P＝0.10).Conclusion Anatomical parameters of the olecranon were measured to provide a reference for the direction，angle and width of the K-wire during tension band operations for olecranon fractures，which will improve the accuracy of such procedures.
