    Introduction: Anterior dislocations, the most common type of shoulder dislocation, are often complicated by subsequent instability. With recurrent dislocations there often is attrition of the labrum and progressive loss of the anterior bony contour of the glenoid. Treatment options for this pathology involve either soft tissue repair or bony augmentation procedure. The optimal management remains unknown and current clinical practice is highly varied. Methods and analysis:The Shoulder instability Trial comparing Arthroscopic stabilization Benefits compared with Latarjet procedure Evaluation (STABLE) is an ongoing multi-centre, pilot randomized controlled trial of 82 patients who have been diagnosed with recurrent anterior shoulder instability and subcritical glenoid bone loss. Patients are randomized to either soft tissue repair (Bankart + Remplissage) or bony augmentation (Latarjet procedure). The primary outcome for this pilot is to assess trial feasibility and secondary outcomes include recurrent instability as well as functional outcomes up to two years post-operatively. Conclusions: This trial will help to identify the optimal treatment for patients with recurrent shoulder instability with a focus on determining which treatment option results in reduced risk of recurrent dislocation and improved patient outcomes. Findings from this trial will guide clinical practice and improve care for patients with shoulder instability. Ethics and dissemination: This study has ethics approval from the McMaster University/Hamilton Health Sciences Research Ethics Board (REB) (approval #4942). Successful completion will significantly impact the global management of patients with recurrent instability. This trial will develop a network of collaboration for future high-quality trials in shoulder instability.

    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.

    (2024) Arteaga, Matías; Vidal Olate, Catalina Victoria; Ruz, Cristián; Zilleruelo Cañas, Raúl Andrés; Pino Piemonte, Ernesto Arnaldo; Dauvergne Ogaz, Javier Alejandro; Besa Vial, Pablo José; Irarrázaval, Sebastián
    Background: Pathologies of the locomotor system are frequent and can cause disability and impact the quality of life of the people affected. In recent years, online training and feedback have emerged as learning tools in many fields of medicine. Objective: This study aims to evaluate medical interns’ musculoskeletal examination performance after completing an online training and feedback module. Methods: This study employed a quasi-experimental design. Medical interns were invited to complete a 4-week musculoskeletal physical examination training and feedback module via an e-learning platform. The course included written and audiovisual content pertaining to medical history, physical examination, and specific tests for the diagnosis of the most common knee, spine, shoulder, ankle, and foot conditions. Before and after completing the module, their ability to perform the physical examination was evaluated using an objective structured clinical examination (OSCE) with simulated patients that took place face-to-face. A control group of experts was assessed using the OSCE, and their performance was compared to that of the interns before and after the training. At the end of the module feedback on the OSCE was provided to participants through the platform asynchronously and two evaluation questions about the user experience were conducted at the end of the study. Results: A total of 35 subjects were assessed using the OSCE, including 29 interns and 6 experts. At the beginning of the training module, the group of interns obtained an average score of 50.6±15.1. At the end of the module, 18 interns retook the OSCE, and their performance increased significantly to an average of 76.6±12.8 (p<0.01). Prior to the training, the experts performed significantly better than the interns (71.2 vs. 50.6; p=0.01). After the interns received the training and feedback, there were no significant differences between the two groups (71.2 vs. 76.6; p=0.43). Two evaluation questions were conducted at the end of the study, revealing that 93% of the participants affirm that the training module will be useful in their clinical practice, and 100% of the participants would recommend the training module to a colleague. Conclusión: The online training and feedback module enhances the musculoskeletal examination performance of medical interns.

    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.

    (2024) Vidal Olate, Catalina Victoria; Poblete Arrué, Fernando Cristian; Rivera González, Sofia Viviana; Besa Vial, Pablo José; Andia Kohnenkampf, Marcelo Edgardo
    Introducción: en el contexto de la implementación de la herramienta de gestión y financiamiento de Grupos Relacionados a Diagnóstico (GRD) en Chile y el aumento de las cirugías por artrosis en Chile; el objetivo de este estudio fue analizar la estancia hospitalaria en pacientes con prótesis de cadera y rodilla en Chile entre el 2019 y 2021 y sus factores asociados. Metodología: se realizó un estudio observacional retrospectivo con datos obtenidos de la base de datos del Grupo Relacionado de Diagnóstico (GRD) de FONASA. Se seleccionaron pacientes con egresos con procedimiento quirúrgico nomenclatura CIE-9 de prótesis y se consideró como criterio de exclusión diagnóstico principal con codificado con nomenclatura CIE-10 relacionada a fracturas. Se recogió información sobre el año de la cirugía, edad, sexo y procedimiento. Se describieron los GRD encontrados y la mediana de estancia para cada uno. Resultados: durante el periodo hubo 7.148 egresos hospitalarios con procedimiento de prótesis de cadera y 4.090 de rodilla. El promedio de edad fue de 66,2 ± 11,9 años y el 62% de las pacientes son de sexo femenino. En pacientes con prótesis de cadera y rodilla se encontró una mediana de estancia hospitalaria de 4 días (0-275) y 3 días (0-101) respectivamente (p<0,001). Se encontró una distribución asimétrica de la estancia dentro de las distintas severidades de un GRD. Conclusión: en el periodo de estudio existió variabilidad en las estancias hospitalarias asociadas a un mismo GRD en pacientes con procedimientos por prótesis de rodilla y cadera.

    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.

    Shoulder surgery in Chile: how far we have come and our future challenges
    (Elsevier Inc., 2025) Marinis Acle, Rodrigo Ignacio de; Vidal Olate, Catalina Victoria; Correa Rivas, Ignacio Andrés; Contreras Fernández, Julio José; Kuroiwa Rivero, Aron Rriky; Calvo Palma, Claudio; Liendo Verdugo, Rodrigo Javier; Cerda, Jaime; Soza Rex, José Francisco
    Shoulder surgery in Chile has seen a remarkable development in the last 2 decades. From a handful of overseas-trained pioneers, Chilean shoulder surgeons now have a growing and robust society with more than 150 members with 8 fellowship programs and around 10 new fellowship-trained shoulder surgeons graduating every year. Academic activity has been steadily improving in both quality and quantity, aspiring to reach the standards of Europe and North America. State-of-the-art clinical practice is the standard in larger cities with considerable access issues in more remote areas of the country. In the broader picture, the country has a mixed public-private insurance system with a health budget that accounts for 9% of the gross domestic product (GDP).27 Although private insurance is accessible to only approximately 18% of the population, the elevated out-of-pocket cost of health care is a growing issue, especially for elective surgery. In this narrative review, we provide an overview of the development of shoulder surgery in Chile. We will discuss our health care system, surgical rates, and waiting lists issues and address the challenges along with opportunities for future developments. By discussing our strengths, limitations, opportunities, and threats, we aim to provide the reader with useful insights into global health care issues around shoulder surgery and exemplify potential solutions and barriers.

    Objetivo: Describir el uso de los cuestionarios reportados por pacientes (patient-reported outcome measures, PROMs, en inglés) en cirugía de tobillo y pie en Chile.Materiales y métodos Estudio descriptivo, transversal, en el que se diseñó y se aplicó una encuesta para conocer el uso de PROMs en Chile. Se invitó a participar a los traumatólogos cuya actividad principal fuese la cirugía de tobillo y pie.Resultados En total, 73 de 110 traumatólogos contestaron la encuesta. El 75% de los encuestados ha utilizado PROMs al menos una vez, y el 50% los utiliza de manera regular. La finalidad con la que se utilizan es principalmente de investigación (83%), y su aplicación es realizada la mayoría de las veces por los médicos del equipo (94%). Se identificaron 15 cuestionarios distintos aplicados en nuestro medio, siendo los más utilizados la Escala Visual Análoga (EVA), la Escala de Tobillo y Retropié de la American Orthopaedic Foot and Ankle Society (AOFAS), el 36-item Short Form Health Survey (SF-36), y la Escala de Resultados de Tobillo y Pie (Ankle and Foot Outcome Score, FAOS, en inglés). Los encuestados que no han utilizado estos cuestionarios señalaron como principales limitantes la falta de información, de tiempo y de personal capacitado.Conclusión El 75% de los traumatólogos dedicados a la cirugía de tobillo y pie encuestados ha utilizado PROMs en su práctica clínica. Existe una amplia variedad de cuestionarios aplicados, y el presente estudio constituye la primera aproximación de su aplicación en nuestro medio.

    Validación de medidas de resultados informados por los pacientes en ortopedia y traumatología
    (2022) Vidal Olate, Catalina Victoria; Lira Salas, María Jesús; Besa, Pablo; Carmona, Maximiliano; Irarrazaval Dominguez, Sebastian
    En los últimos años, ha habido un aumento en la aplicación de cuestionarios diseñados para la medición de resultados (o desenlaces) clínicos en la práctica médica. Para aplicar un cuestionario en una población distinta a la cual fue originalmente creado y diseñado, es necesario llevar a cabo un proceso riguroso de adaptación, con una determinada metodología. El objetivo de esta guía metodológica es describir el proceso de traducción, adaptación transcultural y validación de medidas de resultados informados por los pacientes (MRIPs) en Ortopedia y Traumatología.
