To assess morphological parameters of proximal femur and acetabulum in Thai population with three-dimensional measurement technique, and to analysis of collateral side symmetric, gender difference, and correlation between morphometric parameters.
Investigation was performed in 240 femurs. All three-dimensional femur models were acquitted from 64-slice spiral CT scanner. Morphometric parameters under consideration included acetabular diameter, femoral head diameter, shaft isthmus location, intramedullary canal diameter, diaphyseal diameter, femoral head height, femoral neck isthmus, femoral neck length, neck shaft angle, bow angle, and anteversion angle. All parameters were measured based on functions and least-square regression function in CAD software. Obtained measured data were then used for analysis of collateral side symmetric, gender difference, correlation between morphometric parameters, and compared with other populations.
Female had a smaller dimension compared with male in most of the parameters. No significant difference was observed between left and right femurs. High correlation pairs of morphometric parameters included femoral head diameter-acetabular diameter, femoral head diameter-neck isthmus diameter, femoral head diameter-diaphyseal diameter at shaft isthmus level, acetabular diameter-neck isthmus diameter, neck isthmus diameter-diaphyseal diameter at shaft isthmus level, and acetabular diameter-diaphyseal diameter at shaft isthmus level. Some morphometric parameters of Thai are smaller than other Caucasian, and some Asian nation, i.e. femoral head diameter, femoral neck length, and femoral head height.
This study provides essential morphometric data for various orthopedic implant designs relating to proximal femur region.
采用三维测量技术评估泰国人群股骨近端和髋臼的形态学参数，并分析双侧对称性、性别差异以及形态学参数之间的相关性。
对240个股骨进行研究。所有三维股骨模型均来自64层螺旋CT扫描仪。所考虑的形态学参数包括髋臼直径、股骨头直径、骨干峡部位置、髓腔直径、骨干直径、股骨头高度、股骨颈峡部、股骨颈长度、颈干角、弓角和前倾角。所有参数均基于CAD软件中的功能和最小二乘回归函数进行测量。然后将获得的测量数据用于双侧对称性分析、性别差异分析、形态学参数之间的相关性分析，并与其他人群进行比较。
在大多数参数方面，女性的尺寸比男性小。左右股骨之间未观察到显著差异。形态学参数的高相关对包括股骨头直径 - 髋臼直径、股骨头直径 - 股骨颈峡部直径、股骨头直径 - 骨干峡部水平的骨干直径、髋臼直径 - 股骨颈峡部直径、股骨颈峡部直径 - 骨干峡部水平的骨干直径以及髋臼直径 - 骨干峡部水平的骨干直径。泰国人的一些形态学参数小于其他白种人和一些亚洲国家，即股骨头直径、股骨颈长度和股骨头高度。
本研究为与股骨近端区域相关的各种骨科植入物设计提供了重要的形态学数据。
