文题释义:
下肢力线的概念:下肢力线(膝内翻角)[Lower limbs lines of force]:即股骨机械轴与胫骨机械轴的夹角,理想的角度为0°-5°,国人参考值为:男性(2.2±2.7)°,女性(2.2±2.5)°。股骨机械轴为股骨头圆心与股骨髁间窝顶点的连线,胫骨机械轴为胫骨髁间嵴中点与踝关节中心的连线,踝关节中心取内外踝的中点。从生物力学来说,下肢力线就是“双腿的重力线”。从解剖学来看,下肢力线就是“下肢各器官的结构学连接线”。通俗来讲,下肢力线就是“双腿的线条”。
下肢力线体表测量法:下肢力线的体表测量目前有3种方法:①自股骨头中心至踝关节中心拉一直线,髌骨中点位于此直线上;②自髂前上棘与踝关节拉一直线,该直线通过髌骨中心至髌骨外缘之间,髌骨中点位于其内侧;③自髂前上棘至第1、2趾间拉一直线,髌骨中点位于或接近此直线。
 
摘要
背景:下肢力学轴线角的改变与骨关节炎的发生发展存在着一定的关联性。
目的:分析下肢力线的改变与膝骨性关节炎患者疼痛部位的相关性。
方法:选取膝骨性关节炎疼痛组患者65例和健康对照组患者30例,均行膝关节正侧位片的拍摄,在PACS影像学系统上分别采集Insall 指数(髌骨位置)、股胫关节半脱位程度、股胫内外侧关节间隙比值、股骨角、胫骨角、股胫角这6个影像学指标;将膝骨性关节炎患者疼痛部位分为临床常见的膝前区和膝内侧2个区域。
结果与结论:①膝骨性关节炎疼痛组与健康组患者在Insall 指数、股胫关节半脱位程度、股胫内外侧关节间隙比值的影像学指标比较,差异存在统计学意义;在股骨角、胫骨角和股胫角的比较,差异无显著性意义;②在膝骨性关节炎疼痛组患者的膝内侧和前区的部位比较上,股胫关节半脱位程度的差异有显著性意义;③结果说明,膝骨性关节炎伴膝关节疼痛患者多存在高位髌骨,股胫关节半脱位程度加重,股胫内外侧关节间隙变窄。其中膝前区疼痛患者的股胫关节半脱位程度较膝内侧更加严重。

Abstract:

BACKGROUND: The change of the axial angle of the lower limb is related to the occurrence and development of osteoarthritis.

OBJECTIVE: To analyze the correlation between the change of lower limb power line and pain area in the knee osteoarthritis patients.
METHODS: Totally 65 knee osteoarthritis patients were selected as pain group and 30 healthy people were selected as control group. All the participants took anteroposterior and lateral knee radiographs through PACS imaging systems to collect six imaging indexes, including install index, the degree of tibiofemoral joint subluxation, tibiofemoral inside and outside joint clearance ratio, femoral angle, tibial angle and tibiofemoral angle. Knee osteoarthritis patients in pain group were divided into two common clinical pain areas which were proparea and medial area.
RESULTS AND CONCLUSION: (1) The insall index, the degree of tibiofemoral joint subluxation, tibiofemoral inside and outside joint clearance ratio between knee osteoarthritis patients in pain group and people in healthy control group had significant differences. There was no statistical significance in the femoral angle, tibial angle and tibiofemoral angle. (2) In terms of the comparison between proparea and medial area in knee osteoarthritis patients in pain group, tibiofemoral joint subluxation degree was statistically different. (3) These findings suggest that there was a higher patella in knee osteoarthritis patients who were in pain, more severe in the degree of tibiofemoral joint subluxation, and more limited in tibiofemoral inside and outside joint clearance ratio. The degree of tibiofemoral joint subluxation of proparea was more severe than medial area in pain group.
