Método para la Medición Tomográfica 3D. Caso de Estudio: Displasia de Cadera en niños

Palabras Clave— Cadera, Displasia, Metodo, Tomografia, Tridimensional. Abstract— The display surface of the acetabular hip Computed Axial Tomography 3D in patients over three years with hip dysplasia evidence more accurately the anatomy of this, allowing the overall three-dimensional reconstruction of the pelvis, provides more detailed information anatomy and can help better understand the abnormalities in children. That is why the need for hip scans of patients with this condition arises; with the aim of developing a method that allows us to measure and analyze the entire surface of the acetabulum, as well as having elements to improve patient diagnosis and treatment. A pilot study where scans of 6 patients with longstanding unilateral dysplasia were analyzed by means of design software, and the application of statistical tests performed. The results of our pilot study showed no significant difference between operated and contralateral acetabular acetabular volume volume, but this difference is shown between the surgery performed in different years and the acetabular volume (operated and contralateral). What we can observe is that the percentage difference between the operated and contralateral acetabulum is at three and four years of performing surgery, 8% and 10% respectively. Compared with other patients, where the difference is greater. The method presented in this article simplifies the measurement technique. It is based on the entire geometry of the acetabular structures, compared with two- dimensional images (measurement angles). Providing sufficient for the morphological analysis of postoperative patients with this type of condition elements.
