Deformities of the Hip: Surgical Therapy

1st order

  • Reduction (bringing back to a (near) normal position or normal position).
    • In hip dysplasia:
      • Open reduction – at 4-5 months of age using the anterior (front) approach; as with conservative therapy, retention is in a Fettweis cast (plaster cast for treatment of hip dysplasia or Subluxation of infant hips in dysplasia)Note: Early open reduction (before 12 months of age) reduces the risk of femoral head necrosis (death of bone tissue; due to reduced blood flow, the hip bone demineralizes and loses its stability).
      • Arthroscopic reduction (by arthroscopy) – alternative to open reduction.
      • Proximal femoral osteotomies (thigh realignments) – established surgical technique for hip repositions and residual dysplasia.
    • In acute hip dislocation (dislocation or dislocation of the hip joint).
  • In the case of late effects, corrective surgery and the insertion of a hip endoprosthesis (replacement of a damaged hip joint with an implant) may be necessary.
