概括

功能性膝盖校准在步态分析中,通过结合大腿前转和轴角度,改善了脑儿童部旋转的预测. 然而,仅靠骨形态学并不能完全解释步行过程中的部旋转.

科学领域:

整形外科整形外科整形外科
生物力学生物力学
儿科康复儿童康复中心

背景情况:

股骨形态,包括大三叉体位置,对于步行期间的部绑架至关重要.
脑性麻 (CP) 儿童的股骨形状异常可能会影响下肢功能.
临床步态分析对于儿科CP患者的手术规划至关重要.

研究的目的:

重新检查3D下肢骨形态和关节旋转动力学在CP儿童的步行过程中的关系.
评估功能膝盖校准算法对这种关系的影响.

主要方法:

对121名CP儿童的数据进行二次分析.
使用双平面,低剂量数字X射线系统评估的3D骨形态.
步态分析采用了传统的步态模型,有或没有两个功能性膝盖校准算法.

主要成果:

功能性膝盖校准增强了由线性回归模型解释的差异,将3D骨形态与步行期间的平均部旋转联系起来.
在校准模型中,腿部部前转和部轴角度成为显著的预测因素.
仅靠骨形态并不完全解释部旋转,这表明其他因素的参与.

结论:

功能性膝盖校准提高了骨形态的预测能力,在CP的儿童中,在步行过程中部旋转.
虽然重要,股骨形态并不是唯一决定部旋转的决定因素.
功能校准的局限性,例如软组织工件,需要进一步调查.

Bones of the Lower Limb: Femur and Patella

Bones of the Lower Limb: Femur and Patella

The femur is the body's longest and strongest bone spanning the thigh region. Its head articulates with the acetabulum of the hip bone to form the hip joint. A minor indentation on the medial side of the femoral head, called the fovea capitis, serves as the site of attachment for the ligament of the head of the femur. This weak ligament spans the femur and acetabulum and supports the hip joint. The narrowed region below the head is the neck of the femur. The inclination angle between the...
