    Objetivo: Comparar el riesgo de luxación de la prótesis bipolar de cadera con los abordajes posterolateral y anterolateral en el tratamiento de una fractura de cuello femoral.

    Materiales y Métodos: Se incluyó a pacientes >60 años operados con una prótesis bipolar de cadera por fractura de cuello femoral durante 2021 y 2022. Se determinó la cantidad de luxaciones de prótesis coloca- das con los abordajes posterolateral o anterolateral.

    Resultados: Se incluyeron 79 casos: 46 (58,8%) operados con un abordaje posterolateral y 33 (41,8%) con un abordaje anterolateral. Se produjeron 3 luxaciones con el abordaje posterolateral y 2 con el anterolateral, no se hallaron diferencias significativas (p = 0,655).

    Conclusiones: No se hallaron diferencias entre los abordajes posterolateral y anterolateral respecto del riesgo de luxación de la prótesis bipolar en el tratamiento de una fractura de cuello femoral en el adulto mayor.

    Objective: To compare the risk of bipolar hip hemiarthroplasty dislocation after femoral neck fracture using the posterolateral versus the anterolateral approach.Materials and Methods: Patients older than 60 years who underwent bipolar hip hemiarthro-plasty for femoral neck fracture between 2021 and 2022 were included. The number of dislocations following the posterolateral or anterolateral approach was recorded.Results: Seventy-nine cases were included: 46 (58.8%) were treated with the posterolateral approach and 33 (41.8%) with the anterolateral approach. There were 3 dislocations in the posterolateral group and 2 in the an-terolateral group; no significant differences were found (p = 0.655).Conclusions: There were no differences in the risk of bipolar hemiarthroplasty dislocation between the posterolateral and anterolateral approaches in the treatment of femoral neck fractures in the elderly.
