    Actividad Sexual en Pacientes con Pinzamiento Femoroacetabular. Revisión Narrativa de la Literatura
    (2025) Lira Salas, María Jesús; Klaber Rosenberg, Ianiv; Vidal Olate, Catalina Victoria; Mery I., Pamela; Schweitzer Fernandez, Daniel Alberto
    Introducción: El pinzamiento femoroacetabular (PFA) es una causa común de coxalgia en pacientes jóvenes, afectando movimientos de flexión y rotación profunda, incluyendo las actividades sexuales (AS). El objetivo del estudio fue sintetizar la evidencia sobre RS en pacientes con PFA. Métodos: Se realizó una revisión narrativa de la literatura en las bases de datos Pubmed, Scielo, PEDro y Epistemonikos. Se incluyeron estudios primarios sobre relaciones sexuales en pacientes con PFA.Resultados: Se encontraron siete trabajos publicados entre los años 2014-2024 sobre RS en pacientes con PFA. En los estudios publicados, se han descrito dificultades en las RS asociadas al PFA en el 61 a 91% de los pacientes, siendo las causas principales dolor y rigidez, que inician uno a dos meses después de los síntomas. Se han descrito mejoras post-cirugía en el 29% a 89% de los pacientes, con un reinicio de la actividad sexual entre 29 y 48 días. Las posiciones sexuales con flexión y abducción son las que causan mayores dificultades. No se encontró evidencia sobre la evaluación de las RS en pacientes con PFA por parte de los traumatólogos en la práctica clínica (ejemplo: frecuencia, dificultades, dolor, entre otros). Por último, existe escasa evidencia sobre la educación realizada por parte de los especialistas a los pacientes sobre las relaciones sexuales.Conclusión: El PFA impacta significativamente la actividad sexual, con mejoras reportadas tras la artroscopía en un grupo de pacientes. Las RS son un tema poco abordado por los cirujanos tanto en la evaluación de los pacientes, como en su educación.

    Chilean Cross-Cultural Adaptation and Validation of the Hip Disability and Osteoarthritis Outcome Score
    (2025) Carmona Castillo, Maximiliano; Vidal Olate, Catalina Victoria; Irarrázaval Domínguez, Sebastián; Vial Irarrázabal, Raimundo; Besa Vial, Pablo Jose; Lira Salas, María Jesús; Mery I., Pamela; Guillemin, Francis
    Background The Hip disability and Osteoarthritis Outcome Score (HOOS) has been used for the evaluation of patients who have hip osteoarthritis. It is one of the most frequently used instruments for the follow-up of patients operated on for total hip arthroplasty (THA) in different national registries. The purpose of this study was to carry out the transcultural adaptation and validation of the Chilean version of the HOOS questionnaire in patients who have hip osteoarthritis. Methods The translation and cross-cultural adaptation process were based on international guidelines to obtain a Chilean version of the HOOS questionnaire. The Chilean version was evaluated in the pretest phase and then in the validation phase with patients in the outpatient setting, from patients who had initial osteoarthritis to patients who had end-stage disease waiting for surgery. We assessed the psychometric properties as convergent validity, evaluating correlations with the Short Form 12 Health Survey (SF12) questionnaire and the World Health Organization Disability Assessment Schedule 2.0 (WHODAS2.0) tool; structural validity by conducting a confirmatory factor analysis; and internal consistency using Cronbach’s alpha. Results There were 30 outpatients who participated in the pre-test phase and 111 in the validation phase. There was a positive correlation between the HOOS score in the dimensions of activities of daily living, pain, and symptoms with the physical dimension of the SF12 (r > 0.7; P < 0.001). In the same way, the HOOS quality of life item was correlated with the mental dimension of the SF12 (r = 0.51; P < 0.001). The WHODAS2.0 tool had a moderate negative correlation with all the HOOS dimensions (P < 0.001). Confirmatory factor analysis confirmed good construct validity. Cronbach's alpha was 0.97 for the global questionnaire. Conclusions The Chilean version of the HOOS questionnaire showed adequate validity and reliability, with adequate psychometric properties. This could have relevance in the evaluation and treatment of patients who have hip osteoarthritis and in the evaluation of the results of patients undergoing THA.

    Disparity in access to orthopedic surgery between public and private healthcare insurance: a nationwide population-based study
    (Springer Nature, 2025) Lira Salas, María Jesús; Pino Pommer, Paula; Vidal Olate, Catalina Victoria; Mery I., Pamela; Irarrázaval, Sebastián; Cerda, Jaime; Vergara Leyton, Jorge
    Background This study aimed to evaluate if access to orthopedic surgery differs by healthcare coverage in a country with a dual healthcare system adjusted by age, sex, and urgent and elective conditions. We hypothesize that differential access would exist according to the type of healthcare coverage. This difference would accentuate when analyzing access to elective orthopedic surgery. Methods A cross-sectional, population-based design was used to investigate orthopedic surgery rates in Chile in 2018. The rates of orthopedic surgeries provided under the private and public healthcare systems were calculated per 1,000 inhabitants based on data collected from the Hospital Discharge Registry provided by the Chilean Ministry of Health. ICD-10 diagnoses were classified as urgent or elective, categories into which the public/private surgery rates were also sorted. Results The overall rate of orthopedic surgery was 7.54 per 1000 inhabitants in 2018. Patients covered under private insurance had an orthopedic surgery rate 2.23 times higher than patients within the public system (p-value < 0.001). This difference became more accentuated when sorting by elective surgeries, with private healthcare having a rate 2.97 times higher than public healthcare (p-value < 0.001). In the multivariate analysis, significant differences were observed in the rates of orthopedic surgery, being higher in the private system, elective surgeries, and older adults. No significant differences were observed according to sex (p-value 0.270). Conclusions In Chile, access disparity to orthopedic surgical care existed between private and public healthcare systems, elective surgeries, and older age groups. Disparity in access became greater when separately analyzing the rates of elective and urgent orthopedic surgeries. Level of evidence III.
