Osteoarthritis secondary to congenital hip dysplasia or dislocation poses great difficulties for the surgeon reconstructing the hip. Cases with little deformity do not differ practically from conventional primary reconstruction. At the opposite end there are cases with severe acetabulum hypoplasia, poor femoral development, complete dislocation, significant limb discrepancy, and great thrust of the greater trochanter. Due to the enormous difficulties that they can represent for surgery, we set the objective of discussing our case, with the considerations and results of the chosen treatment. A 54-year-old female patient is reported, she has previous health history, and she came for consultation with severe congenital deformity, shortening of her right lower limb (6 cm) and painful limitation of all hip movements. Congenital dislocation grade C of Hartofilakidis and IV of Crowe was confirmed, which showed as part of the treatment, the total arthroplasty with autologous graft and reimplantation of the cup in the true acetabulum, to recover the center of rotation of the acetabulum and the shortening femoral osteotomy for implantation of the femoral stem. Requirements, technical procedures and results achieved are informed.
