Exploración ecográfica de las caderas del bebé en mochilas de porteo / Evaluation by ultrasound of the hips of babies carried in baby carriers

Antecedentes y objetivo: La displasia de cadera se ha asociado con factores de riesgo como la presentación de nalgas, el sexo femenino o los antecedentes familiares. Sin embargo, factores externos, como los sistemas de porteo, parecen influir en el desarrollo de la cadera en los primeros meses de vida. El objetivo del presente trabajo es valorar por imagen ecográfica la posición de las caderas en bebés colocados en diferentes tipos de mochilas portabebés. Método: Se ha realizado un estudio ecográfico de las caderas de bebés sanos entre 1,5 y 3,5meses de edad, cuando el niño es porteado en tres diferentes mochilas portabebés que proporcionan diferentes grados de sujeción de los muslos del bebé. Todas las caderas eran tipoI de Graf. Se han valorado tres parámetros ecográficos: el ángulo alfa de Graf, la cobertura acetabular y la distancia a pubis en situación basal (mesa de exploración) y en las tres diferentes mochilas de porteo. Resultados: En todos los casos los bebés mostraron valores de normalidad en los tres parámetros estudiados, sin diferencias estadísticamente significativas entre ninguna de las situaciones. Tampoco se encontraron diferencias en los parámetros ecográficos relacionadas con el sexo, la edad o el peso del bebé. Conclusiones: La cadera derecha del bebé mantiene unos parámetros ecográficos de normalidad cuando es colocada en cualquiera de los modelos de mochila estudiados

Background and objective: Hip dysplasia has been associated with risk factors such as breech presentation, female gender or family history. However, external factors, such as the use of baby carriers, seem to influence the development of the hip in the first months of life. The aim of this study is to evaluate the position of the hips of babies placed in different types of baby carriers by ultrasound image. Method: An ultrasound study of the hips of healthy babies between 1.5 and 3.5 months of age was carried out, when the children were carried in three different baby backpacks, which provide different degrees of support for the babies' thighs. All hips were typeI according to the Graf classification. Graf's alpha angle, acetabular coverage and distance to the pubis were assessed at baseline (examination table) and when the children were carried in the three different backpacks. Results: In all cases, the babies showed normal values in the three studied parameters, without statistically significant differences between any of the situations. There were also no differences in the ultrasound parameters related to the sex, age or weight of the baby. Conclusions: The right hip of the babies shows normal ultrasound parameters when placed in any of the baby carriers studied
