The human femur is commonly considered as a subsystem of the locomotor apparatus with four conspicuous levels of organization. This phenomenon is the result of the evolution of the locomotor apparatus, which encompasses both constitutional and individual variability. The work therein reported, therefore, underlies the significance of observing anatomical system analysis of the proximal femur meta-epiphysis in normal conditions, according to the anatomic positioning with respect to the right or left side of the body, and the presence of system asymmetry in the meta-epiphysis structure, thus indicating structural and functional asymmetry.
A total of 160 femur bones of both sexes were compiled and a morphological study of 15 linear and angulated parameters of proximal femur epiphysis was produced, thus defining the linear/angulated size of tubular bones. The parameters were divided into linear and angulated groups, while maintaining the motion of the hip joint and transmission of stress to the unwanted parts of the limb. Furthermore, the straight and vertical diameters of the femoral head and the length of the femoral neck were also studied. The angle between the neck and diaphysis, the neck antiversion and angle of rotation of the femoral neck were subsequently measured. Finally, the condylo-diaphyseal angle with respect to the axis of extremity was determined. To visualize the force of intersystem ties, we have used the method of correlation galaxy construction.
The absolute numeral values of each linear parameter were transformed to relative values. The values of superfluidity coefficient for each parameter in the right and left femoral bone groups were estimated and Pearson's correlation coefficient has been calculated (> 0.60). Retrospectively, the observed results have confirmed the presence of functional asymmetry in the proximal femur meta-epiphysis. On the basis of compliance or insignificant difference in the confidence interval of the linear parameters, we have revealed, therefore, a discrepancy in values between the neck and the diaphysis angle and the angle of femoral neck rotation (range displacement of confident interval to a greater degree to the right).
This study assessed the observations of a systemic anatomical study encompassing the proximal femur meta-epiphysis behavior in normal condition. This work has significance in medical practice as the theoretical basis is also required in knowing the decreased frequency and degree of severity of osteoarthritic pathologies in the dominant lower extremity.
人类股骨通常被认为是运动器官的一个子系统，具有四个明显的组织层次。这种现象是运动器官进化的结果，既包括体质变异，也包括个体变异。因此，报告中的工作强调了在正常情况下观察近端股骨骺端的解剖系统分析的重要性，这种分析是根据身体左右侧的解剖定位以及骺端结构中系统不对称的存在来进行的，从而表明结构和功能的不对称性。
共编译了 160 根男女股骨，并对近端股骨骺端的 15 个线性和角度参数进行了形态学研究，从而确定了管状骨的线性/角度大小。这些参数被分为线性和角度两组，同时保持髋关节的运动和向肢体非期望部位传递应力。此外，还研究了股骨头的直径和垂直直径以及股骨颈的长度。测量了颈干角、颈扭转和股骨颈旋转角度。最后，确定了与肢体轴的髁干角。为了可视化系统间联系的力，我们使用了相关星系构建的方法。
每个线性参数的绝对值都被转换为相对值。估计了右侧和左侧股骨组中每个参数的超流系数，并计算了 Pearson 相关系数（>0.60）。回顾性地，观察结果证实了近端股骨骺端存在功能不对称。基于线性参数置信区间的合规性或不显著差异，我们发现颈干角和股骨颈旋转角度之间存在差异（置信区间范围向右侧更大程度地移位）。
本研究评估了对正常条件下近端股骨骺端行为的系统解剖学研究的观察结果。这项工作在医学实践中具有重要意义，因为也需要理论基础来了解优势下肢骨关节炎病理的发生频率和严重程度降低。
