ABSTRACT
Brazilian populational aging besides higher life expectancy has increased the incidence of proximal femoral fractures. Treatment of those fractures uses implants which are based in measurements performed in caucasians, including the 135 degrees cervical-diaphyseal angle. Knowing femoral morphometry allows evaluating implants adequability. We performed our study using 110 Brazilian human femurs (49 right and 61 left). We excluded from the study bones submitted to osteosyntesis, to prosthetization or those showing abnormalities or malformations which could affect its structure and shape. Bones were submitted to roetgenographic analysis and the images were scanned and transferred to personal computer. Measurements were obtained by AutoCad software and statistics by Graph Pad Instat software. Our data were compared using Kolmogorov-Smirnov and "t-test". The following parameters were evaluated femoral head diameter (FHD), femoral neck length (FNL), femoral neck width (FNW), femoral axis length (FAL), off-set (OS) and cervical-diaphyseal angle (CDA). The findings were as follows (mean +/- SD), right and left sides respectively FHD, 31.1 +/- 2.7 mm and 30.8 +/- 3.0 mm; FNL, 30.1 +/- 4.3 mm and 30.5 +/- 4.1mm; FNW, 30.96 +/- 2.94 mm; FAL, 98.2 +/- 5.9 mm and 97.4 +/- 7.13 mm; OS, 42.6 +/- 6.1 mm and 42.0 +/- 5.6 mm; CDA, 132.0 +/- 7.2 e 131.8 +/- 5.2. Median cervical-diaphyseal angle, obtained in this study presented some variation, which was not statistically significant. Linear data are constant, according to other studies, except the off-set, which has varied.
RESUMEN
Junto al envejecimiento de la población de Brasil, producto de la mayor expectativa de vida, ha aumentado la incidencia en las fractura de la parte proximal del fémur. Para el tratamiento de estas fracturas se utilizan implantes, los que están basados en mediciones realizadas en caucásicos, incluido los 135 grados del ángulo cervico-diafisario. Conocer la morfometría femoral permite evaluar adecuabilidad de los implantes. Se realizó este estudio con 110 fémures humanos (49 derechos y 61 izquierdos) de individuos brasileños. Se excluyeron del estudio los huesos sometidos a osteosíntesis, a prótesis o en los que se detectaron anormalidades o malformaciones que pudieran afectar su estructura y forma. Los huesos fueron sometidos a análisis radiográfico y las imágenes digitalizadas y transferidas a un computador personal. Las mediciones se obtuvieron mediante el software AutoCAD y las estadísticas con el software Instat. Nuestros datos se compararon con la prueba de Kolmogorov-Smirnov y "t-test". Los siguientes parámetros fueron evaluados diámetro de la cabeza del fémur (FHD), longitud del cuello femoral (FNL), ancho del cuello femoral (FNW), longitud del eje del fémur (FAL), off-set (OS) y el ángulo cérvico-diafisario (CDA). Los resultados fueron los siguientes (media +/- SD), a la derecha e izquierda respectivamente FHD, 31,1 +/- 2,7mm y 30,8 +/- 3,0 mm; FNL 30,1 +/- 4,3 mm y 30,5 +/- 4,1mm; FNW 30,96 +/- 2,94mm; FAL 98,2 +/- 5,9mm y 97,4 +/- 7,13mm; OS 42,6 +/- 6,1mm y 42,0 +/- 5,6mm; CDA 132,0 +/- 7,2 y 131,8 +/- 5,2. Los ángulos cérvico-diafisarios medianos obtenidos en este estudio presentaron alguna variación, que no fue estadísticamente significativa. Los datos lineales fueron constantes en acuerdo con otros estudios, excepto el off-set, que ha variado.
