Ángulo acetábulo-epifisario y luxación de cadera en la parálisis cerebral: Estudio preliminar / Acetabular-epiphyseal angle and hip dislocation in cerebral palsy: a preliminary study

Objetivo: Relacionar, en sujetos con parálisis cerebral no deambulantes, el porcentaje de migración de Reimers con medidas radiológicas estandarizadas, incluyendo el ángulo acetábulo-epifisario. Método: Estudio descriptivo, observacional y transversal de 15 individuos, de edades comprendidas entre 3 y 9 años, con parálisis cerebral, pertenecientes a los niveles IV y V del Gross Motor Function Classification System. Se realizaron medidas radiológicas del índice acetabular, el ángulo epifisario de Hilgenreiner, el ángulo acetábulo-epifisario, el ángulo cérvico-diafisario y el porcentaje de migración de Reimers de cada una de las caderas. Resultados: Se obtuvieron correlaciones entre el índice acetabular, el ángulo epifisario y el ángulo acetábulo-epifisario respecto al porcentaje de migración de Reimers. Para las caderas con un porcentaje de migración igual o menor del 15% se observó correlación positiva entre los ángulos acetabular y epifisario. Conclusiones: En nuestra población, la medida entre la inclinación acetabular y epifisaria es la que mayor asociación presenta con el porcentaje de migración de la cadera

Objective: To relate, in non-ambulatory subjects with palsy, Reimers' migration percentage with standardized radiological measurements, including the acetabular-epiphyseal angle. Method: Descriptive, observational and transversal study of 15 individuals with cerebral palsy at levels IV and V of the Gross Motor Function Classification System, aged between 3 and 9 years. Radiological measurements of the acetabular index, Hilgenreiner's epiphyseal angle, acetabular-epiphyseal angle, neck-shaft angle and Reimers’ migration percentage of each of the hips were performed. Results: Correlations between acetabular index, epiphyseal angle and acetabular-epiphyseal angle were obtained with respect to the Reimers migration percentage. For hips with a migration rate of 15% or less, a positive correlation was observed between acetabular and epiphyseal angles. Conclusions: In our population, the measurement between acetabular and epiphyseal inclination represents the highest association with the hip migration percentage
