“…In the interest of defect downsizing, impaction bone grafting should be applied. Several publications report good mid-and long-term results and the observation of bone mineral density changes, which can be interpreted as a progressive apposition of vital new host bone [4,14,15]. Impaction bone grafting has proven itself to be a valid method of treatment and should be used in contained defects or severe defects in combination with other methods of reconstruction.…”

Introduction The treatment of severe acetabular bone loss remains a difficult challenge. No classification system is available that combines intuitive use, structured design and offers a therapeutic recommendation according to the current literature and modern state of the art treatment options. The goal of this study is to introduce an intuitive, reproducible and reliable guideline for the evaluation and treatment of acetabular defects. Methods The proposed Acetabular Defect Classification (ADC) is based on the integrity of the acetabular rim and supporting structures. It consists of 4 main types of defects ascending in severity and subdivisions narrowing down-defect location. Type 1 presents an intact acetabular rim, type 2 includes a noncontained defect of the acetabular rim ≤ 10 mm, in type 3 the rim defect exceeds 10 mm and type 4 includes different kinds of pelvic discontinuity. A collective of 207 preoperative radiographs were graded according to ADC and correlated with intraoperative findings. Additionally, a randomized sample of 80 patients was graded according to ADC by 5 observers to account for inter-and intra-rater reliability. Results We evaluated the agreement of preoperative, radiographic grading and intraoperative findings presenting with a k value of 0.74. Interobserver agreement presented with a k value of 0.62 and intraobserver at a k value of 0.78. Conclusion The ADC offers an intuitive, reliable and reproducible classification system. It guides the surgeon pre-and intraoperatively through a complex field of practice.

“…La literatura describe varias técnicas para alcanzar un adecuado press-fit cuando se emplean copas no cementadas, desde un underreaming de 2 mm, hasta un reaming de 1 mm de línea a línea. [28][29][30] En nuestra experiencia utilizamos 1 mm de underreaming con una copa completamente hemisférica y no elíptica técnica validada en la literatura para el implante que utilizamos. [30][31][32] En nuestro caso, el componente de prueba es considerado imprescindible para estos pacientes, para asegurarse que la cantidad de injerto a utilizar en el fondo es adecuada.…”

“…[34][35][36][37] El uso de copas no cementadas, como es la práctica más frecuente en nuestro país, también tiene un resultado exitoso respaldado en la literatura. [29][30][31] La serie más relevante fue publicada por el grupo de la Clínica Mayo, 38 que demostró 85% de sobrevida de copas no cementadas. Es destacable que el 40% de estas copas fueron posicionadas sin tornillos, confiando absolutamente en el press-fit alcanzado durante la cirugía.…”

ResumenLos pacientes candidatos a artroplastía total de cadera con protrusio acetabular asociada generan distintos desafíos en los equipos quirúrgicos. Múltiples estrategias han sido utilizadas a lo largo de los años para optimizar los resultados. Mediante una revisión de la evidencia actualizada disponible, proponemos diez tácticas a realizar en el manejo de estos pacientes que pueden mejorar y hacer predecible el tratamiento de un paciente con protrusio acetabular al que se le realiza una artroplastía total de cadera. Nivel de Evidencia V.
