Total Hip Replacement Using Hemi-Circumferential Interposition Acetabuloplasty for Acetabular Deficiency in Post-Perthes Deformities: Technique and Long-Term Results
Abstract:We describe a technique of hemi-circumferential interposition grafting that allows placement of the cup in the anatomical position of the original acetabulum in the rare cases of post-Perthes or Perthes-like deformities of the femoral head combined with a steep and shallow acetabulum. This technique was performed on 10 hips (9 patients, with an average age of 56 years). One revision was performed for septic loosening after 2.1 years; however, the graft was well integrated and provided sufficient support for th… Show more
