Relación entre medidas radiológicas y morfología de cadera en individuos con parálisis cerebral: serie de casos

Abstract

BackgroundIn cerebral palsy (CP), there are different processes and muscle forces that affect the biomechanical developmental behaviour of the hip joint. This study aims to present the differences between radiological measurements as regards peri-articular hip musculature and the bone morphology. Materials and methodsDescriptive, observational and cross-sectional study of 14 individuals, aged between 6 and 10 years, with CP at levels IV and V of the Gross Motor Function Classification System (28 hips). Radiological measurements were performed on the gluteus medius, gluteus minimus, quadratus femoris, and pectineus. Reimer's migration percentage and neck-shaft angle for each of the hips were also evaluated. ResultsA direct relationship was observed between distances as regards the gluteus medius and minimus, with respect to pectineus, and an inverse one of all with respect to quadratus femoris. The neck shaft angle showed an inverse relationship with the proportions for the quadratus femoris, both in proportion to the gluteus medius and pectineus. DiscussionIn the studied population, there is an association between an adequate length of the pelvic-trochanteric musculature with respect to the abductor and adductor and near-normal neck shaft angles, with measurements of shortening of the quadratus femoris being negative. Evidence levelIV.
