Morphological research at the proximal femur on the three-dimensional reconstruction leaded by MRI for the adult developmental hip dysplasia
Abstract
The three-dimensional reconstruction is beneficial to observe the injured portion better. It provided the all-around treatment choices. Our study aimed to discuss the effect of the three-dimensional reconstruction leaded by MRI on the morphology. The iconographical assessment was performed for patients by LCEA (Front and rear view), acetabular inclination (AI) (Front and rear view), and anterior central margin angle (ACEA). Patients with dysgenesis at different degree was detected through HE and IHC. The principal component analysis was performed by DDH leaded under MRI. The baseline characteristics of patients was consistent basically. The center of caput femoris was lateral obviously in patients with DDH mild form and proximal notably in patients with DDH heavy type under MRI. There was more extensive vascularization and inflammatory cell infiltration in the synovial membrane of hip joint in the development of DDH from the moderate type to heavy type. The staining strength of SP and CGRP in patients with heavy type DDH was significantly higher than those in patients with moderate type DDH and control group. The patients with DDH were treated through the three-dimensional reconstruction leaded by MRI which could improve the intertrochanteric osteotomy combined with periacetabular osteotomy. The thighbone is adjusted moderately so as to improve the coverage of caput femoris and recover or maintain the limb alignment
