摘要
目的通过测量成人胫骨解剖轴与前缘骨皮质间的夹角,了解两者相对位置关系,以指导人工全膝关节置换术中胫骨髓外定位杆的放置。方法以100名成年健康志愿者为研究对象,男52名,女48名。年龄20～86岁,平均45.2岁;其中20～35岁29名,35～50岁32名,≥50岁39名。左膝49名,右膝51名。摄标准胫腓骨侧位X线片,采用AutoCAD2004软件测量胫骨解剖轴与前缘骨皮质夹角角度;分别按照性别、年龄、侧别分组进行统计学分析。结果成人胫骨解剖轴与前缘骨皮质夹角为3.007～3.021°,平均3.001°。其中,男性为(2.965±0.361)°,女性为(3.041±0.311)°;左膝为(2.996±0.332)°,右膝为(3.006±0.347)°;20～35岁为(2.918±0.346)°,35～50岁为(3.060±0.330)°,≥50岁为(3.014±0.336)°;不同性别、侧别及年龄组间比较,差异均无统计学意义(P>0.05)。结论成人胫骨解剖轴与前缘骨皮质夹角约为3°,人工全膝关节置换术中胫骨髓外定位杆与前方骨皮质保持3°左右夹角为宜。
Objective To measure the included angle between tibia anatomical axis and anterior cortex,and to define the relative position of them in order to give direction in placement of tibia extra-medullary alignment bar during total knee arthroplasty.Methods A total of 100 healthy volunteers were included（49 left knees and 51 right knees）.There were 52 males and 48 females,aged 20-86 years with an average age of 45.2 years（20-35 years in 29 cases,35-50 years in 32 cases,and over 50 years in 39 cases）.The tibiofibular lateral X-ray films were taken to measure the included angle between tibia anatomical axis and anterior cortex with AutoCAD2004 system.The samples were grouped according to gender,age,and side.Results The included angles between tibia anatomical axis and anterior cortex ranged from 3.007 to 3.021° with an average of 3.001°;the angles were（2.965 ± 0.361）° in male and（3.041 ± 0.311）° in female;the angles were（2.996 ± 0.332）° in the left knee and（3.006？± 0.347）° in the right knee;and the angles were（2.918 ± 0.346）° in 20-35 years age group,（3.060 ± 0.330）° in 35-50 years age group,and（3.014？± 0.336）° in over 50 years age group.No significant difference was found in the included angle between tibia anatomical axis and anterior cortex between male and female,among different ages,and between left and right knees（P？ 0.05）.Conclusion The included angle between tibia anatomical axis and anterior cortex is about 3°,so tibia extra-medullary alignment bar should be placed at the angle of 3° with anterior cortex during total knee arthroplasty.
