Computer-Assisted Comparative Analysis of Acetabular Volume and Surface Morphology in Pediatric Acetabular Osteotomies (Salter, Dega, San Diego, and Pemberton)

What this Trial Is About

Researchers are studying how four different acetabular osteotomy techniques—Salter, Dega, San Diego, and Pemberton—affect the shape and volume of the hip socket in children and adolescents with developmental dysplasia of the hip or residual acetabular dysplasia. This observational study aims to compare virtual simulations of these osteotomies with early postoperative MRI scans to understand how closely the virtual models match actual surgical outcomes. Participants will undergo routine clinical care involving one of the four acetabular osteotomy procedures selected by their surgeon based on their specific hip deformity. Before surgery, a three-dimensional model of the pelvis and acetabulum will be created from an MRI taken within 6 weeks. Virtual versions of each osteotomy technique will be applied to this model to predict changes in hip socket morphology. Early postoperative MRI scans taken 3 to 8 weeks after surgery will be used to compare the actual surgical results with the virtual predictions. During the study, researchers will analyze differences in hip socket volume and surface shape among the osteotomy methods, measure agreement between virtual and actual postoperative morphology, and assess measurement reliability. They will also evaluate the time and success rate of the imaging and analysis process. Participants will have their preoperative and postoperative MRIs assessed, and the total study involvement includes imaging and data analysis over a period extending up to about 14 weeks.
