Factores relacionados con el éxito en la protetización de amputados de extremidad inferior de etiología vascular / Factors related to success in the prosthetic fitting of lower limb amputees from vascular etiology

Objetivos: Recuperar la capacidad de deambulación con prótesis en los amputados de extremidad inferior es fundamental para mejorar su independencia funcional. El objetivo de este trabajo ha sido conocer qué factores intervienen en conseguir la protetización de pacientes amputados vasculares. Material y método: Estudio longitudinal observacional de los pacientes con amputación mayor de extremidad inferior de etiología vascular realizada desde el 1 de abril de 2017 hasta el 1 de abril de 2020. Se compararon las siguientes variables entre los pacientes que fueron protetizados y los que no: edad, sexo, índice de masa corporal, comorbilidades (escala de Charlson), independencia en las actividades de la vida diaria básicas (índice de Barthel) y capacidad de marcha (FAC) previas y al año de la amputación. La utilización de la prótesis al año se midió con el instrumento de Houghton. Resultados: Fueron amputados 80 pacientes con una edad media de 70,5 años, el 78,8% eran varones. El nivel de amputación fue supracondíleo en 42 pacientes y en 38 infracondíleo; se protetizaron 35. Las variables relacionadas con la posibilidad de protetización fueron la menor edad (p=0,020), presentar menos comorbilidad (p=0,00), la amputación infracondílea (p=0,024) y tener una mayor independencia funcional y de marcha previas a la amputación (p=0,00). Al año habían fallecido 22 pacientes, solo uno de los que fueron protetizados. Conclusión: Aunque no existen unas recomendaciones claras para determinar qué amputado ha de ser protetizado, en nuestros pacientes, tener menos comorbilidades, una buena situación funcional previa, menor edad y un nivel de amputación infracondíleo se relacionaron con un mayor éxito en conseguir dicho objetivo.(AU)

Objective: Restoring the ambulation ability with prostheses in lower limb amputeesis essential to improve their functional independence. The aim of this study was to determine the factors involved in achieving prosthesis fitting in vascular amputees. Material and method: Observational longitudinal study of patients with major lower limb amputation of vascular etiology performed from April 1st 2017 to April 1st 2020. The following variables were compared between the group of patients who were prosthetized and those who were not: age, gender, body-mass index, comorbidity (Charlson index), independence in the activities of daily living (Barthel index) and ambulation ability (FAC test) before and a year after the amputation. The prosthetic use after a year was measured with the Houghton scale. Results: A total of 80 patients were amputated with a mean age of 70.5 years old, 78.8% were male. The amputation level was supracondilealin 42 patients and infracondilealin 38 patients. The number of prosthetized patients was 35. The variables related to the possibility of prosthesis fitting were: younger age (P=0.020), less comorbidity (P=0.000), infracondileal amputation (P=0.024) and greater functional independence and ambulation ability prior to amputation (P=0.000). After a year 22 patients had died, only one of those who had been prosthetized. Conclusions: Although there are no clear recommendations to determine which amputees should be prosthetic fitting, in our patients the presence of fewer comorbidities and a good previous functional situation, younger age and infracondileal amputation, are related to greater success in achieving this objective.(AU)
