Aim: Since the joints of adult patients with developmental dysplasia of the hip (DDH) differ significantly from normal anatomy, surgery in these patients poses many additional challenges. The aim of this study was to quantify the anatomical differences between the hips of individuals with normal hips on one side and high hip dislocation on the other side.Material and Methods: Twenty computed tomography images of unoperated patients with one normal hip and one high hip dislocation (Hartofilakidis type C) were retrospectively analyzed. The acetabulum was analyzed with seven measurements and the femur with 16 measurements.Results: The mean acetabular volume of the normal side was 2.3 times that of the dislocated side, the depth was 1.5 times that of the dislocated side, the anteroposterior diameter was 1.58 times that of the dislocated side, and the mean posterior lip thickness was 3.61 times that of the dislocated side. The femoral cortical thickness of the dislocated hip was thinner, the femoral anteversion angle was higher and the trochanter minor was more retroverted than the normal side. Although the total length of the dislocated side was less, we observed that the femur of the dislocated side was longer distally than the trochanter minor.Discussion: Patients with unilateral high DDH had significant changes in both the acetabulum and the intact side. We recommend a thorough pre-assessment and preparation to prevent complications during total hip arthroplasty surgery as part of DDH treatment.
