Three-dimensional Reconstruction Of Congenital Hip Dysplasia In The Application Of Value

Objective:Through a review of clinical studies, three-dimensional CT reconstruction through thehip bone of the anatomical structures observed cases of hip dysplasia and hipstructure compared with the normal structure to understand the disease of hipdysplasia hip structural alterations, For the treatment of hip dysplasia, structuralrepair to provide accurate reference data.Subjects and methods:For nearly 2 years in our hospital,32 patients with unilateral congenital hip dysplasiawere retrospectively reviewed the clinical study. According to literature, design their own measure, the eligible patients are divided into Treatment group of hips, health hip into control group, by calculating two sets of acetabular index, femoral head height, femoral neck anteversion, femoral head size, and then On two sets of data for statistical analysisusing SPSS13.0 preliminary study of congenital hip dysplasia and proximal femoralacetabular development impacts, and increased with age and proximal femoralacetabular morphology.Results:1.The study included 32 cases of patients aged 0 to 8 years old,0-1 years 4cases,1-2 years 4cases,2-3years 4cases,3-4 years 4cases,4-5 years 4cases,5-6 years 4cases,6-7 years 4 cases,7-8years 4cases. male 3, female 29;hips to the right side in 9 cases,23 cases of hips to the left.2.After the three-dimensional reconstruction from CT images observed ipsilateralacetabular bone defects in different degrees,9 cases in the acetabulum before thetop of the acetabulum in 18 cases at the top, after the 5 patients in the top of the acetabulum.3. After omparing the data measured after the same patients suffering from hip and health hip acetabular index, femoral neck anteversion, femoral head sizes aresignificantly different, the femoral head was no significant difference in height;risk ofhip acetabular indes 1-4 Slight decrease at the age of 8 years old,4-acetabular indexwas not changed.The age of the femoral head height was no significant difference infemoral neck anteversion decreased 1-3 years,4-8,no significant changes in femoral head volume increases with age, but the magnitude of the increase Compared with thecontralateral Significantly reduced;contralateral hip acetabular index, femoral neck anteversion decreased during development, height and femoral head femoral headvolume increased gradually during development, increased.Conclusion:1. congenital hip dysplasia in patients with head and acetabulum due to loss ofnormal relationship between the acetabulum without the femoral head stress anddefects of different degrees, the femoral head of the external force not slow development of acetabular, femoral neck anteversion The effect of abnormalbiomechanical point of view is too large.2.0-3 years of age suffering from hip acetabular index,femoral neck anteversion and femoral head size of a self-healing ability, with age a significant difference of each index,3-8-year-old is in the slow growth period, no significant differences in the indicators.3. In this study, age contralateral hip acetabular index decreased during development (29.11to14.77), femoral neck anteversion has also decreased during development(45.96to19.89),height and size of the femoral head Increases with age.
