Resumen: Introducción: La hemiartroplastía bipolar (HA) es una alternativa para el tratamiento de las fracturas desplazadas de cuello femoral en pacientes de edad avanzada con baja demanda funcional y comorbilidades asociadas. El objetivo fue describir la funcionalidad en pacientes mayores de 65 años con fracturas intracapsulares de cadera tratados con HA. Material y métodos: Revisión retrospectiva de pacientes mayores de 65 años entre Enero de 2012 y Mayo de 2017. Se evaluó con la escala de Harris (HHS) y Oxford a los seis meses y al año posterior a la cirugía. Se documentaron las complicaciones y la mortalidad durante el primer año postquirúrgico. Resultados: 48 casos (12 hombres; 36 mujeres), edad promedio de 80.8 ± 7.7 años. Comorbilidades más frecuentes: hipertensión arterial (77.1%), osteoporosis (37.5%), diabetes (33.3%) e hipotiroidismo (29.2%). El porcentaje de complicaciones postoperatorias asociadas fue de 8.3% (cuatro casos). La mediana del HHS a los seis y 12 meses fue de: 90.5 (DE: 77.5-96.0) y 96 (DE: 92-98), respectivamente. La escala de Oxford fue de 45.5 (DE: 38.5-48.0) a los seis meses y de 47.0 (DE: 43.5-48) al año postoperatorio. El 4.2% (dos casos) fallecieron durante el primer año postquirúrgico y ninguno estuvo asociado al procedimiento. Discusión: La HA ofrece buenos resultados funcionales en pacientes mayores de 65 años, con una tasa baja de complicaciones. En nuestra serie y en el corto plazo no se observó mortalidad asociada al procedimiento quirúrgico.

Abstract: Introduction: Bipolar hemiarthroplasty is an alternative for the treatment of displaced femoral neck fractures in elderly patients with low functional demand and associated comorbidities. The goal was to describe functionality in patients over 65 years of age with intracapsular fractures of the hip. Material and methods: Retrospective review of patients over 65 years of age between January 2012 and May 2017. It was evaluated with the Harris Hip Score (HHS) and Oxford scale at six months and the year after surgery. Complications and mortality were documented during the first post-surgical year. Results: 48 cases (12 men; 36 women), average age of 80.8 ± 7.7 years. Most common diseases: high blood pressure (77.1%), osteoporosis (37.5%), diabetes (33.3%) hypothyroidism (29.2%). The percentage of associated postoperative complications was 8.3% (four cases). The median HHS at six and 12 months was: 90.5 (DE: 77.5-96.0) and 96 (DE: 92-98), respectively. The Oxford scale was 45.5 (DE: 38.5-48.0) at six months and 47.0 (DE: 43.5-48.0) per postoperative year. 4.2% (two cases) died during the first post-surgical year and none were associated with the procedure. Discussion: HA provides good functional outcomes in patients over 65 years of age, with a low rate of complications. No mortality associated with the surgical procedure was observed in our series and in the short term.

Use of cuff tear arthroplasty head prosthesis for rotator cuff arthropathy treatment in elderly patients with comorbidities / Utilização de prótese do tipo cabeça cuff tear arthroplasty para o tratamento de artropatia do manguito rotador em pacientes idosos e com comorbidades

ABSTRACT Objective To evaluate the clinical and functional behavior of patients undergoing cuff tear arthroplasty at different stages of the disease. Methods Cuff tear arthroplasty hemiarthroplasties were performed in 34 patients with rotator cuff arthropathy and associated comorbidities, classified according to Seebauer. The mean age was 76.3 years, and the sample comprised 23 females (67.6%) and 11 males (32.4%). The mean follow-up period was 21.7 months, and evaluations were performed using the Visual Analog Scale for pain and the Constant scale. Results There were no statistically significant differences in the mean reduction in the Visual Analog Scale or in the Constant scale increase between the female and male groups. The variation between the pre- and postoperative Visual Analog Scale and Constant scale evaluations was significant. There was also no statistically significant difference between the Seebauer classification groups regarding the mean Visual Analog Scale reduction, or the mean Constant scale increase. Conclusion Cuff tear arthroplasty shoulder hemiarthroplasty is a good option for rotator cuff arthropathy in patients with comorbidities.

RESUMO Objetivo Avaliar o comportamento clínico e funcional dos pacientes submetidos à artroplastia do tipo cuff tear arthroplasty para o tratamento da artropatia do manguito rotador em diferentes estágios da afecção. Métodos Foram realizadas 34 hemiartroplastias do tipo cuff tear arthroplasty em 34 pacientes com artropatia do manguito rotador e comorbidades associadas, classificadas de acordo com Seebauer. A média de idade foi de 76,3 anos, sendo 23 pacientes do sexo feminino (67,6%) e 11 do sexo masculino (32,4%). O seguimento médio foi de 21,7 meses e a avaliação foi realizada por meio da Escala Visual Analógica da dor e pela escala de Constant. Resultados Não houve diferença estatisticamente significante entre os grupos feminino e masculino, tanto nas médias de redução na Escala Visual Analógica quanto nas de aumento na escala de Constant. A variação entre as avaliações da Escala Visual Analógica e da escala de Constant pré e pós-operatórias foi significante. Não houve diferença estatisticamente significante entre os grupos de classificação de Seebauer quanto às médias de redução na Escala Visual Analógica e nem quanto às médias de aumento na escala de Constant, e não houve casos de infecção. Conclusão A hemiartroplastia do ombro tipo cuff tear arthroplasty é boa uma opção nos pacientes com artropatia do manguito rotador, especialmente em pacientes com comorbidades.

Hemiprótesis de Austin Moore en fracturas mediales de cadera desplazadas. Tasa de mortalidad, infección y luxación en 91 pacientes con mal estado general / Austin Moore hemiprosthesis for intracapsular hip fracture. Analysis of mortality, infection and dislocation in 91 patients

Introducción: Las fracturas de cadera son muy frecuentes en ancianos. La hemiartroplastia es un tratamiento aceptado para las fracturas mediales desplazadas en pacientes ancianos y con baja demanda funcional. El objetivo de este trabajo es documentar la tasa de mortalidad a los 30 días y al año, y las complicaciones asociadas en pacientes con mal estado general. Materiales y Métodos: Desde 2003 hasta 2010, se operaron 1134 pacientes con diagnóstico de fractura medial de cadera. El 9% (101) fue tratado con hemiprótesis de Austin Moore, y 91 de ellos fueron incluidos en esta serie. Todos eran deambuladores intradomiciliarios y tenían múltiples comorbilidades asociadas. La supervivencia fue evaluada con el método de Kaplan-Meier; y la asociación entre mortalidad y sexo, infección y luxación, con un modelo de regresión de riesgos proporcionales de Cox. Resultados: Setenta pacientes eran mujeres (77 %) y la media de la edad era de 85 años. La mortalidad fue del 7 % a los 30 días y del 36 % al año. Diez pacientes (11 %) presentaron algún episodio de luxación protésica y 13 (14,3 %) sufrieron una complicación infecciosa. La asociación entre infección/mortalidad y sexo masculino/mortalidad fue estadísticamente significativa (p = 0,009 y p = 0,013). Los pacientes con infección tuvieron una tasa más alta de luxación (p = 0,00001). Conclusión: La hemiartroplastia con prótesis de Austin Moore es una alternativa válida para pacientes con fractura medial desplazada, baja demanda funcional y mal estado general, pues es un procedimiento rápido, que elimina el dolor, y permite una movilidad precoz...

Background: Hip fractures are common in elderly people. Hemiarthroplasty is an accepted treatment for intracapsular fractures of the hip in elderly patients with low functional demands. The objective of this study is to show the 30-day and 1-year mortality rates and associated complications in patients with bad performance status. Methods: Between 2003 and 2010, 1,134 patients with intracapsular fractures of the hip were treated. One hundred and one patients (9 %) were treated with Austin Moore hemiprosthesis and 91 of them were included in this series. All were toddlers in their homes and they had multiple comorbidities. Kaplan-Meier estimator was used to evaluate survival. Mortality was then related to sex, age, infection and dislocation using a Cox proportional hazards regression model. Results: Seventy patients were women (77 %) and the mean age of the series was 85 years. The 30-day and 1-year mortality rates were 7 % and 36 %, respectively. Ten patients (11 %) had an episode of prosthetic dislocation and 13 (14.3 %) had an infectious complication. Infection/mortality and male/mortality associations were statistically significant (p = 0.009 and p = 0.013). Patients who suffered an infection had a higher rate of dislocation (p = 0.00001). Conclusion: Hemiarthroplasty with Austin Moore prosthesis is a good option for patients with displaced intracapsular hip fractures, low activity demand and multiple comorbidities, since it is a quick procedure that eliminates pain, allowing early mobility...
