摘要

目的　基于中国南方人群股骨外翻角（femoral valgus angle，FVA）和股骨弯曲角（femoral bending angel，FBA）的定量分析，探究下肢旋转体位改变对不同形态股骨的FVA测量值的影响，提高膝关节置换手术的安全性。方法　收集我院75位（113侧）无膝关节骨性关节炎患者的下肢全长CTA扫描数据。通过三维重建和定位，测量FBA和FVA。根据FBA分为4组：严重内翻畸形组：FBA＞4°；轻度内翻畸形组：1°＜FBA≤4°；无畸形组：-1°≤FBA＜1°；外翻畸形组：FBA≤-1°，对比各组的FVA，确定FBA与FVA之间的相关性。应用三维模拟技术，以股骨后髁连线与X轴平行时作为股骨中立位，每10°为一个档位，调节股骨轴向旋转角度从内旋20°至外旋40°，记录FBA与FVA测量值，并作相关统计分析。结果　总体FVA平均值为（5.3±1.4）°，4组FVA分别为（7.2±1.1）°，（3.4±0.8）°，（5.6±0.87）°及（4.7±1.0）°，各组间存在统计学差异（P<0.05）；FBA与FVA存在显著相关性（R2＝0.6，P<0.001）。下肢从内旋20°至外旋40°，各组的FVA呈增大趋势，各组间无统计学差异（P>0.05）。结论　股骨干形态存在内翻或外翻畸形时，直接影响股骨外翻角的大小。股骨外翻角的测量需综合考虑股骨干形态及下肢旋转体位的影响。

Abstract

Objective　To explore the effects of rotation position change of lower limbs on the femoral valgus angel (FVA) measurement of different forms of femur and to improve the safety of knee replacement surgery based on the quantitative analysis of the FVA and femoral bending angel (FBA) in patients from southern China. Methods Computed tomography angiography (CTA) scan data of 75 patients (113 sides) without osteoarthritis (OA) in our hospital were collected. Femoral bowing angle (FBA) and femoral valgus angle (FVA) were measured by 3D reconstruction and location.. The following four groups were divided according to FBA: a severe varus deformity group: FBA>4°; a mild varus deformity group: 1°0.05). Conclusions　Valgus or varus deformity of femoral shaft has direct influences on the value of FVA. The measurement of FVA should always consider the influence of femoral shape and rotation angle.
