A Comparative Study of Sagittal Spinal-Pelvic Parameters Between Patients with Adolescent Idiopathic Scoliosis and Healthy Controls

Abstract

This study aimed to investigate the sagittal spinal-pelvic morphological changes, as well as the relationship between pelvic anatomical changes and the spinal-pelvic plane in patients with adolescent idiopathic scoliosis (AIS), in order to provide guidelines for orthopedic surgery in AIS. X-ray data were collected for retrospective analysis from 30 patients diagnosed as AIS in the Departments of Radiology at the Second Affiliated Hospital of Inner Mongolia Medical University and the Inner Mongolia International Mongolian Medical Hospital from April 2014 to November 2018, along with 30 normal adolescents as control. Pelvic parameters, including pelvic incidence (PI), pelvic tilt (PT), and sacral slope (SS), a spinal parameter, lumbar lordosis (LL), and anatomical parameters, including sacral width (SW) and femoral head-sacrum distance (FH-S), were measured. The spinal-pelvic parameters were compared between AIS patients and normal controls and also between male and female AIS patients. Pearson correlation was performed to analyze correlation between spinal-pelvic parameters and between spinal-pelvic parameters and anatomical parameters in both AIS patients and normal controls. PT was significantly lower in AIS patients than in normal controls (P < 0.05), whereas no significant difference was found in the other spinal-pelvic parameters, i. e. , LL, PI, and SS. There was a significant difference in PT between sexes in AIS patients. SS was significantly correlated with LL in EIA patients (P < 0.05, r > 0.5). SS was significantly correlated with LL and PI, and PT with LL, PI, and SS in normal controls (all P < 0.05), and there was no significant correlation between the other sagittal spinal-pelvic parameters (P > 0.05). FH-S was significantly correlated with LL, PI, SS, and PT in AIS patients (all P < 0.05). AIS affects some of the sagittal spinalpelvic parameters and anatomical parameters. In AIS, there is a significant correlation between the spinal-pelvic parameters, and the anatomical parameter is significantly correlated with multiple spinal-pelvic parameters.

The Influence of Martial Arts on Spine CT Image Morphological Structure Based on Optimized Ant Colony Algorithm

“…As can be seen from formula (13), the heuristic function increases with the increase of cluster radius, that is, the probability of selecting the corresponding cluster center increases. In addition, the heuristic function decreases with the increase of the distance between the pixel and the cluster center, that is, the probability of ant individuals selecting the corresponding cluster for merging decreases.…”

“…Through the improved CT image segmentation method of the optimized ant colony algorithm, this paper analyzes all aspects of the experimental object's spinal CT images before and after the experiment [ 12 ]. This paper is mainly divided into three parts [ 13 ]. The first part expounds the influencing factors of spinal morphological structure development and the harm of abnormal development; the second part is the construction of the spine development evaluation model based on optimized ant colony; the third part is the experimental results and analysis of the influence of spine shape and structure of Wushu team based on the optimized ant colony algorithm [ 14 ].…”
