Los casos con escasa deformidad no difieren prácticamente de la reconstrucción primaria convencional. En el extremo opuesto están los casos con graves hipoplasias del acetábulo, escaso desarrollo femoral, luxación completa, discrepancia importante de las extremidades y gran cabalgamiento del trocánter mayor. Por las enormes dificultades que pueden representar para la cirugía, nos trazamos el objetivo de discutir nuestro caso, con las consideraciones y resultados del tratamiento elegido. Se presenta paciente femenina de 54 años de edad, con antecedentes de salud previa, que nos llegó a consulta con una grave deformidad congénita, acortamiento del miembro inferior derecho (6 cm) y limitación dolorosa de todos los movimientos de la cadera. Se constata una luxación congénita grado C de Hartofilakidis y IV de Crowe, que muestra como parte del tratamiento, la artroplastia total con injerto autólogo y reimplantación del cótilo en el acetábulo verdadero, para recuperar el centro de rotación del acetábulo y la osteotomía femoral de acortamiento para la implantación del vástago femoral. Se exponen los requerimientos, procederes técnicos y resultados alcanzados.]]></p></abstract>
<abstract abstract-type="short" xml:lang="en"><p><![CDATA[ABSTRACT 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.]]></p></abstract>
