双侧股骨内外侧髁解剖学

Anatomy of bilateral femoral lateral condyle

目的测量股骨髁的某些形态参数,确定股骨髁在形态方面是否存在左右差异。方法收集郑州大学解剖学教研室的股骨111个(左侧64个和右侧47个),用游标卡尺测量相关数据。结果股骨的平均双髁宽度为左侧(7.79±0.56)cm,右侧(7.66±0.40)cm(P>0.05)。内侧髁长度相对值是左侧(6.09±0.53)cm和右侧(5.97±0.41)cm(P>0.05);外侧髁长度为左侧(6.06±0.43)cm和右侧(6.00±0.41)cm(P>0.05);髁间宽度为左侧(1.92±0.24)cm和右侧(1.83±0.16)cm(P>0.05);髁间深度为左侧(2.94±0.25)cm和右侧(2.90±0.25)cm(P>0.05)。提示双侧的股骨髁各项数据在统计学上没有明显的差别。结论双侧股骨髁的一致性可能是设计全膝关节假体的理论基础,健侧膝关节可用于术前制作患侧模板。

Objective To perform a direct measurement of Chinese processed bones and to record certain parameters of the femoral condyle for determining femoral condyle about whether there are differences in form. Methods The femurs provided by the Anatomy Department of Zhengzhou University were measured with a vernier caliper 111 （ left side 64 and right 47）. Results The average width of the femoral condyle was （7.79 ± 0.56） cm on the left, （7.66 ± 0.40） cm on the right （P 〉 0.05 ）. Relative value of the length of the medial condyle was （6.09 ± 0. 53） cm on the left and （5.97 ± 0. 41 ） cm on the right （ P 〉 0. 05 ）. The length of the lateral epicondyle （ 6. 06 ± 0.43 ） cm （left） and （ 6. 00 ± 0.41 ） cm （right） （P 〉 0. 05 ）. Intercondylar width on the left was （ 1.92 ± 0. 24） cm and on the right （ 1.83 ± 0. 16 ） cm （P 〉 0. 05）. Intercondylar depth was （2.94 ± 0. 25） cm on the left and （2. 90 ± 0. 25 ） cm on the right （ P 〉 0. 05）. The difference of bilateral femoral condyles were not statistically significant. Conclusion The consistency of bilateral femoral condyle may be the design theory of total knee prosthesis, and the contralateral joint can be used to make patients before the template.
