Se realizó una evaluación de la reducción radiográfica y resultado funcional de los pacientes con fractura compleja de acetábulo sometidos a abordaje combinado Kocher-Langenbeck y Stoppa.  Material y métodos:  Diseño transversal, descriptivo, ambispectivo. Se incluyeron pacientes con fractura compleja de acetábulo que se sometieron a abordaje combinado Kocher-Langenbeck y Stoppa entre 2016 y 2020. Se revisaron los expedientes clínicos y se evaluó la calidad de la reducción radiográfica según criterios de Matta. Además, se realizó evaluación funcional con la escala de Merle d&#8217;Aubigné y Postel pasados por lo menos 12 meses de la lesión.  Resultados:  De los 31 pacientes, el tiempo promedio entre la fecha de fractura y la intervención quirúrgica fue de 13.7 días (de tres a 38 días). En la evaluación radiográfica según criterios de Matta, 21 pacientes tuvieron resultados radiográficos anatómicos (67.7%), siete casi anatómicos (22.5%) y tres imperfectos (9.6%). Los resultados funcionales según la escala Merle d&#8217;Aubigné y Postel dieron como resultado ocho pacientes (25.8%) con resultados excelentes, 16 (51.6%) con resultado bueno, con resultado moderado cinco (22.5%) y con resultado malo dos (16.1%). Hubo correlación estadística entre la edad del paciente con el resultado funcional (p = 0.029), también entre el índice de masa corporal y pérdida sanguínea (p = 0.027).  Conclusión:  Los abordajes combinados Kocher-Langenbeck y Stoppa son una alternativa en estas lesiones, en su mayoría con resultados radiográficos anatómicos y casi anatómicos, según la escala radiográfica de Matta, y con excelentes y buenos resultados funcionales, según la escala de Merle d&#8217;Aubigné y Postel.]]></p></abstract>
<abstract abstract-type="short" xml:lang="en"><p><![CDATA[Abstract:  Introduction:  Complex acetabulum fractures are a challenge for orthopedic surgeons. An evaluation of the radiographic reduction and functional result of the patients with complex fracture of the acetabulum who underwent the combined Kocher-Langenbeck and Stoppa approach was carried out.  Material and methods:  Cross-sectional, descriptive, ambispective design. Patients with complex acetabulum fracture who underwent the combined Kocher-Langenbeck approach plus Stoppa between 2016 and 2020 were included. The clinical records were reviewed, and the quality of the radiographic reduction was evaluated according to Matta criteria. In addition, a functional evaluation was performed with the Merle d&#8217;Aubigne and Postel scale at least 12 months after the injury.  Results:  Of the 31 patients, the average time between the date of fractures and the surgical intervention was 13.7 days (3-38 days). In the radiographic evaluation according to Matta criteria, 21 anatomical patients (67.7%), 7 almost anatomical (22.5%), 3 imperfect (9.6%). Functional results according to the Merle d&#8217;Aubigne and Postel scale resulted in 8 (25.8%) with excellent results, 16 (51.6%) with good results, 5 (22.5%) moderate and 2 (16.1%) poor patients. There was a statistical correlation between the age of the patient and the functional result (p = 0.029), also between the body mass index and blood loss (p = 0.027).  Conclusion:  The combined Kocher-Langenbeck plus Stoppa approaches are a valid alternative in these lesions, mostly with anatomical and almost anatomical radiographic results according to the Matta radiographic scale, and with excellent and good functional results according to the Merle d&#8217;Aubigne and Postel scale.]]></p></abstract>
