  • When the acetabular cup is placed at the level of the true acetabulum, the bone defect caused by acetabular dysplasia may result in poor cup coverage (CC) in THA 1 , 2 , thus leading to unsatisfactory initial stability and low long-term survival rate 3 - 5 . (researchsquare.com)
  • The high hip center (HHC) technique placing the acetabular cup above the true acetabulum during acetabular reconstruction, is suitable for DDH patients, because it can make full use of the bone above the true acetabulum to ensure adequate host bone coverage of the cup 12 , 13 . (researchsquare.com)
  • In the present study, we firstly evaluated the CC of acetabular cup models with different sizes in patients with Crowe type Ⅱ and type Ⅲ DDH using the HHC technique to reconstruct the acetabulum, then analyzed the CC of host bone in all hips when reconstructing acetabulum at the true acetabulum with 44-mm acetabular cup models.
