ABSTRACT
To design custom-made prosthesis in a certain population, the morphometry needs to be measured. The results of this study were expected to provide basic data to design the ideal size of the total hip arthoplasty prosthesis for Indonesian population. This was an anthropometric study conducted on sex matched 100 healthy Indonesian mongoloid race subjects based on Computer Tomographic (CT) imaging on the proximal femur. The parameters being used in this study were Femoral Head Offset (FHO), Femoral Head Position (FHP), Femoral Head Diameter (FHD), Neck-Shaft Angle (NSA), Anteroposterior Width (APW) and Mediolateral Width at 3 different locations, and Canal Flare Index (CFI). This study showed that Indonesian has smaller proximal femur morphometry as compared to Western population. The mean value of all parameters in male were larger than female. Moreover, FHO and FHP showed significant difference among male and female indicating the location of male femoral head center lies superiorly as compared to female. The dimension of femoral canal was found to be mediolaterally oval, 1.43, 1.28, and 1,34, respectively, in 3 different cutting (20 mm above and 40 mm below lesser trochanter, and isthmus). CFI of Indonesian was classified to be stovepipe femoral canal (2.99) that is the suggestion to use cemented femoral stem. This study showed that Indonesian proximal femur dimension has smaller build compared with Western counterpart. The proposed dimensions can be used as the basic data to design the ideal size of the femoral stem for Indonesian population.
RESUMEN
Para diseñar prótesis a medida en una población determinada, la morfometría necesita ser conocida. El objetivo de este estudio fue obtener resultados que sean útiles en la investigación para diseñar el tamaño ideal de una prótesis total de artroplastía de cadera para la población de Indonesia. Fue realizado un estudio antropométrico en 100 sujetos sanos de raza mongoloide de Indonesia, en los que se estudió la parte proximal del fémur por tomografía computadorizada (TC). Se consideraron como parámetros la cabeza del fémur (CF), posición de la cabeza del fémur (PCF), diámetro de la cabeza del fémur (DCF), ángulo cérvicodiafisario (ACD), ancho anteroposterior (AAP) y ancho-lateral en 3 lugares diferentes. La población Indonesia tiene una morfometría menor del fémur proximal en comparación con la población occidental. El valor medio de todos los parámetros en hombres fueron mayores a las mujeres. Por otra parte, CF y PCF mostraron diferencia significativa entre hombres y mujeres e indicó una ubicación superior del centro de la cabeza del fémur en hombres, en comparación con las mujeres. Se encontró que la dimensión del canal femoral fue mediolateral oval, 1,43, 1,28, y 1,34, en 3 cortes diferentes, respectivamente (20 mm superior y 40 mm inferior del trocánter menor e istmo). La dimensión del fémur proximal en la población de Indonesia es de menor tamaño en comparación con la contraparte occidental. Las dimensiones propuestas se pueden utilizar como datos básicos para el diseño de un tamaño ideal de vástago femoral para la población Indonesia.
