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.

(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.
¿Cómo es la calidad de vida reportada por los estudiantes de Medicina?
(2018) Irribarra Trivelli, Luis Alfonso; Mery I., Pamela; Lira Salas, María Jesús; Campos Daziano, Mauricio Andrés; González L., Francisca; Irarrázaval, Sebastián
Background: The high academic burden may hamper the quality of life of medical students. Aim: To evaluate the quality of life (QOL) for medical students attending a Chilean university. Material and Methods: Four hundred eleven medical students aged 22 ± 2 years (51% women), studying in Santiago, Chile, answered online a validated Spanish version of the WHOQOL-BREF quality of life survey (scored from 0 to 100). Overall scores were assessed for the questionnaire domains Physical health, Psychological health, Interpersonal relationships, and Environment. Results: The global scores were 65.1 for Physical health, 63.1 for Psychological health, 61.3 for Interpersonal relationships and 67.2 for Environment. Students in clinical practice, females, those with sedentary behaviors and consuming modafinil had lower Physical health scores. Students coming from outside Santiago, with sedentary behaviors and who consumed modafinil had poorer Psychological health scores. Students coming from outside Santiago, males and those with sedentary behaviors had Lower Interpersonal relationship scores. Environment scores were also lower among students who were sedentary or from outside Santiago. Conclusions: The variables that had a greater negative impact in the quality of life of these students were the transition from theoretical courses to clinical practice, being from outside Santiago, being overweight or obese and consuming modafinil. Students that were physically active had better quality of life scores.
Contamination rate of the surgical gowns during total hip arthroplasty
(2019) Klaber Rosenberg, Ianiv Walter; Ruiz, Pablo; Schweitzer Fernandez, Daniel Alberto; Lira Salas, María Jesús; Botello Correa, Eduardo Andrés; Wozniak Banchero, Aniela
Introduction: Surgical instrument contamination during total joint replacement is a matter of major concern. Available recommendations suggest changing suction tips, gloves and avoiding light handle manipulation during the procedure. There is a paucity of data regarding surgical gown contamination. The aim of the present study was to evaluate the contamination rate of surgical gowns (SGs) during total hip arthroplasty (THA) and secondarily compare it with other orthopedic procedures. Materials and methods: One hundred and forty surgical gowns (from 70 surgeries) were screened for bacterial contamination using thioglycolate (a high-sensitivity culture broth). The THA contamination rate was compared with those of knee and spine procedures. Controls were obtained at the beginning of every surgery and from the culture broth. The procedure’s duration and the level of training of the surgeon were evaluated as potential risk factors for contamination. Results: Bacterial contamination was identified on 12% of surgical gowns (22% of surgical procedures). The contamination rate during THA was 4.1% (2% in primary THA and 8.3% in revisions) vs 21.67% during other surgeries (spine and knee) (OR 6.15, p = 0.012). There were no contaminated SGs during THAs performed in ≤ 2 h (0/33 SGs) vs 7.5% (3/40) for THAs that took ≥ 2 h (p = 0.25). Conclusion: There was a high rate of SG contamination during orthopedic procedures that was higher during non-arthroplasty procedures and prolonged THAs. There were no contaminated surgical gowns in THAs under 120 min, efforts should point keeping primary THAs under this cutoff time. As a general recommendation, SGs should be changed every time there is concern about potential contamination. © 2019, Springer-Verlag GmbH Germany, part of Springer Nature.
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.

(2023) Morales Diaz, Sergio Luis; Valdivia Cabrera, Gonzalo Sergio; Botello Correa, Eduardo Andrés; Klaber Rosenberg, Ianiv Walter; Carmona Castillo, Maximiliano; Lira Salas, María Jesús
Propósito del estudio: Describir las preferencias educativas de los beneficiarios de las Garantías Explicitas en Salud (GES) que fueron sometidos a una cirugía de endoprótesis total de cadera. Material y método: Se diseñó una encuesta que exploró las preferencias educativas referentes a cada etapa del proceso quirúrgico de adultos mayores sometidos a endoprótesis total de cadera en un centro hospitalario universitario. Se seleccionó el total de pacientes operados en el centro durante el año 2019. La encuesta se aplicó de manera telefónica por un encuestador entrenado. El tiempo entre la aplicación de la encuesta y la cirugía fue entre 2 y 14 meses. Resultados: Se incluyeron 63 pacientes, cuya edad promedio fue 72,5 años y el 69,8% correspondía al sexo femenino. Con respecto a su cobertura de salud el 57,2% era beneficiario de FONASA y el 42,7% de ISAPRE. Las preferencias de información descritas en nuestra muestra con respecto al proceso quirúrgico desde su inicio a fin, señalan la cirugía (40,4%) y los cuidados post operatorios (29,3%) como los temas de más interés. Los temas de menor interés fueron los cuidados preoperatorios (45,2%) y la información relacionada a la hospitalización (31,7%). Los pacientes encuestados valoraron la información entregada previa a su cirugía como adecuada, útil y fácil de entender. Conclusiones: Los adultos mayores sometidos a endoprótesis señalaron la información específica referente a la cirugía y los cuidados post operatorios como los temas educativos de mayor interés. La información estándar entregada por los médicos tratantes fue bien recibida por los pacientes.
Evaluation of the Chilean National Orthopaedic Examination Over 11 Years: Progress and Outcomes of National and International Examinees
(LIPPINCOTT WILLIAMS & WILKINS, 2024) Lira Salas, María Jesús; Besa Vial, Pablo José; Irarrázaval Dominguez, Sebastián; Ruz Laurent, Cristian Andrés; Walbaum, Garcia Cristóbal; Montecinos, Carla; Amenabar, Diego; Orrego Luzoro, Mario Santiago
Introduction: The National Orthopaedics Examination (EMNOT) was initially designed for Chilean orthopaedic program graduates and is now a crucial component of the revalidation process for international orthopaedic surgeons seeking practice in Chile. This study aims to describe participation and performance of EMNOT examinees based on their origin and to analyze the difficulty and discrimination indexes during its first 11 years of implementation. Methods: A retrospective assessment was conducted on all EMNOT results from 2009 to 2019. The study evaluated the participation and performance of examinees according to their origin and examined the difficulty and discrimination indexes of the examination.Results: A total of 975 examinees were evaluated, with 41.23% from national resident programs (National Medical Graduates) and 58.77% from international examinees (International Medical Graduates). The number of participating universities increased from 4 in 2009 to 17 in 2019. National Medical Graduates examinees achieved a mean score of 66.52 +/- 8.67 (0 to 100 points) while International Medical Graduates examinees scored 55.13 +/- 11.42 (P , 0.001). The difficulty and discrimination indexes remained adequate throughout this period. Discussion: Over the course of 11 years, the number of EMNOT examinees exhibited notable growth. The examination effectively differentiates between candidates based on their origin and maintains appropriate levels of difficulty and discrimination.
Increasing incidence of rotator cuff surgery : a nationwide registry study in Chile
(2021) Vidal Olate, Catalina Victoria; Lira Salas, María Jesús; Marinis Acle, Rodrigo Ignacio de; Liendo Verdugo, Rodrigo Javier; Contreras, Julio J.
Background: The rotator cuff surgery (RCS) incidence is rising rapidly in North America, Europe, Asia, and Australia. Despite this, multiple factors limit patients’ access to surgery. In Latin America, barriers to orthopedic surgery have been largely ignored. The purpose of this study was to calculate the rate of RCS in Chile between 2008 and 2018, investigating possible associated factors to access such as age, sex, and the health insurance. Methods: An ecological study was carried out with nationwide data obtained from the Database of Hospital Discharges of the Department of Statistics. All Chilean inhabitants aged 25 years or more were included. We used the ICD-10 codes M751, M754, and S460. The annual incidence rate of surgeries and the incidence rate for the period studied per 100,000 inhabitants were calculated. Data were analyzed stratified by age, sex, year of study, and the health insurance. Negative binomial regression was used to compare rates. Statistical analyzes were performed with Stata v.14 software. Results: 39,366 RCSs were performed, with a total rate for the period of 32.36 per 100,000 inhabitants. The annual rate of surgeries from 2008 to 2018 increased from 24.55 to 49.11 per 100,000/year. When adjusting for year, an annual increase in surgery rates of 8.19% (95% CI 6.7–9.6) and 101% growth between 2008 and 2018 (95% CI 90–109%, p < 0.001) was observed. When comparing the global rates according to the health insurance, the public system corresponds to 21.3 per 100,000 and the private system to 72 per 100,000, the latter being 3.4-times higher (95% CI 2.7–4.4; p < 0.001). Conclusion: RCS rates are increasing in Chile concordantly with previous reports of other western countries. The most important factor associated with RCS rate found was the patients’ health insurance, with higher rates observed for the private sector.
Increasing surgical rate of clavicle fractures and acromioclavicular dislocations in Chile: analysis over the last 15 years reveals disparities in access according to insurance type
(Springer Nature, 2025) Vidal Olate, Catalina Victoria; Marinis Acle, Rodrigo Ignacio de; Liendo Verdugo, Rodrigo Javier; Silva Canales, Isadora Camila del Carmen; Lira Salas, María Jesús; Contreras Fernández, Julio José
Background In recent years, an increase in surgeries to treat clavicle injuries has been reported. It has been hypothesized that the studies regarding the beneficial effect of surgery in patients with displaced clavicle fractures may have contributed to raise the surgical rates for injuries around the clavicle. To our knowledge, there is a lack of data from Latin American countries on surgical rates of clavicle-related surgeries. The aim of this study is to describe the rate of clavicle surgeries, including clavicle fracture and acromioclavicular dislocation, in the last 15 years and to analyze the possible effect of sex, age, and health insurance in those rates. Methods An observational cross-sectional study was carried out. Patients over 18 years old diagnosed with the following ICD-10 codes were selected: S420 "Clavicle fracture", S431 "Dislocation of the acromioclavicular joint", and S435 "Sprains and strains of the acromioclavicular joint". We collected information on the year of surgery, sex, age and type of insurance. The annual rate of surgeries and the rate for the period studied per 100,000 people were calculated. The rate was compared through negative binomial regression, reporting Incidence Rate Ratios (IRR) with 95% confidence interval (95% CI). Results During a 15 years period of observation, 24,570 surgeries were performed. For clavicle fractures an 8.0 × 100,000 surgical rate was observed, and a 4.7 × 100,000 rate was found for acromioclavicular dislocations. The surgical rate for clavicular injuries increased from 2.8 in 2005 to 19.1 in 2019. Rates were higher in men, and ages between 20 and 35 years. The surgical rate for clavicular injuries in the public system was 11.1 × 100,000 and 30.9 × 100,000 in the private system, which represents a difference of 2.8 times between those healthcare systems. Conclusion There has been a significant increase in clavicle and acromioclavicular dislocation surgeries in Chile, with disparities influenced by age, gender, and type of health insurance.

Background: The delay in the diagnosis of AIDS results in higher treatment costs. Aim: To reveal the experiences of people who were diagnosed in the AIDS stage about the access to the ELISA test. Material and Methods: In depth interviews were carried out to 15 participants from public hospitals who were in the AIDS stage at the moment of the diagnosis. The main questions asked were about the motivations to take the test, the barriers found and the help received from the health care personnel. All interviews were recorded and analyzed according to Kripperdorff. Results: The three categories that emerged were the motivations to take the test, the facilitators found and the difficulties to access to the test. The main motivation was a condition of vulnerability due to the suspicion or certainty of being infected. The main facilitator was the sensation of being accepted and not discriminated. The main difficulties were the fear of having a positive test and of being discriminated and the lack of information. Conclusions: Knowing these experiences will help to improve the early detection of HIV infections.
