Abstract EN
Periacetabular osteotomy (PAO) is a complex surgical procedure to restore acetabular coverage in the dysplastic hip, and the amount of acetabular rotation during PAO plays a key role.
Using computational simulations, this study assessed the optimal direction and amount of the acetabular rotation in three dimensions for a patient undergoing PAO.
Anatomy-specific finite element (FE) models of the hip were constructed based on clinical CT images.
The calculated acetabular rotation during PAO were 9.7°, 18°, and 4.3° in sagittal, coronal, and transverse planes, respectively.
Based on the actual acetabular rotations, twelve postoperative FE models were generated.
An optimal position was found by gradually varying the amount of the acetabular rotations in each anatomical plane.
The coronal plane was found to be the principal rotational plane, which showed the strongest effects on joint contact pressure compared to other planes.
It is suggested that rotation in the coronal plane of the osteotomized acetabulum is one of the primary surgical parameters to achieve the optimal clinical outcome for a given patient.
