How closely does the virtual result of the osteotomy actually performed match the early postoperative magnetic resonance imaging (MRI)?\n\nParticipants will have a three-dimensional pelvis-acetabulum model created from preoperative MRI. Researchers will perform virtual Salter, Dega, San Diego, and Pemberton osteotomies on that model and measure the resulting acetabular morphology. The virtual result of the osteotomy actually performed will then be compared with the participant's early postoperative MRI.",[26,27,28],"Developmental Dysplasia of the Hip (DDH)","Developmental Dysplasia of the Hip","Acetabular Dysplasia",[30,31,32,33,34,35,36,37,38,39],"Salter osteotomy","Dega osteotomy","San Diego osteotomy","Pemberton osteotomy","Developmental dysplasia of the hip","Acetabular dysplasia","Magnetic resonance imaging","Three dimensional modeling","Acetabular morphometry","Methodological validation","RECRUITING","2026-06-24",{"date":43,"type":44},"2026-06-26","ACTUAL",{"date":46,"type":44},"2026-05-10",{"date":48,"type":22},"2026-10-15",{"name":50,"class":51},"Istanbul University","OTHER"]
